How to Groove and Sipe Asphalt Pull-off Tires for a Race Car and talking my History and Experiences
ฝัง
- เผยแพร่เมื่อ 5 เม.ย. 2021
- We are processing a used asphalt tire for use on dirt by grooving and siping, covering tire grooving iron setup durometer readings and and discussing differences in synthetic or natural rubber tires. Additionally I am going into detail about some of my history racing and why it is very important we support new and struggling racers.

This sport will chew you up and spit you out as a new racer. If it wasn't for folks like you, Rabbit, Brian, and Ashley helping me out, I can't say I'd have stuck it out. Can't tell ya how much I appreciate it!
I love tire prep! So relaxing. I would put on some music or TH-cam videos and knock out a whole set in one sitting.
Yep, I like to put on some racing on TH-cam and just go at it. Its a good time to just focus on racing a d what you need to do to improve.
You are spot on with the comments about helping. Our class went from a 350 class to a 400 class and when it was a 350 class we had 20 to 30 cars a night, After changing to a 400 class they are lucky to get 5.
I have 7 tracks that are in a circle about 2 hours drive for me and I can see this difference track to track also.
Just like many other comments I've seen; I'm grateful that you are sharing your knowledge and experiences. Even in 2022 a lot of local tracks make it difficult to gather the information required to break into the entry level. I feel that's a big down fall.
Also, understandably a lot of drivers and crews keep their knowledge and experiences as a safe guarded secret. Which again makes the entry level so daunting to break into.
Thank you for all your time and effort.
Love that you try to help the new people
Thanks Steve, I wish I could do more and make more videos than what I am doing but I do what I can.
Thanks for this channel. Getting in a dirt car is moving it’s way up to the top of my bucket list at a rapid pace.
Thats great to hear Ross, I wish you the best in this epic adventure of dirt racing :)
Good stuff sir. Learned a ton. Thank you.
Thank you for watching sir
Love it bud. Keep up the good work.
Thanks Wolfpack
Appreciate all your shared knowledge. I've been watching all your videos trying to get caught up. The only issue I'm having is that your videos are making me second guess the safety in my wife's car, so I keep adding things to it, pushing me back further but I think we'll be ready by next year. And it's all for the best I couldn't handle it if mama got hurt
i know the feeling there. When I put my kid in the camaro the first thing was getting her a full containment seat, sfi5 suit, head restraint, etc before anything else.
Hey dirt race Life! I love your videos! I've been in and around racing for around 30 years off n on. And I gotta say you are one of my favorite type of folks to learn from! You always explain what you say. I Can usually tell when someone is teaching, if they are teaching from their own experience and theory or if they are just repeating something that someone told them and they really don't even know what they are saying lol. No you are not the latter... Don't get me wrong, nothing wrong with the latter except sometimes that's crap I loose sleep over trying to reverse engineer and figure why 😂. For most part, I won't do anything to my car with out understanding the logic. Of course sometimes if I fight something so long, then I start throwing logic out.
So it's really nice having a teacher that speaks and I don't have to loose sleep trying to figure the lesson 😂
Thank you sir!
Jay
Very kind words Jay that are much appreciated. I am aware I am not an expert and am still learning. That's the reason I focus so hard on being completely candid and explain exactly how I came to each conclusion I make. As you watch me work through the new coil car setup over last season you can see my understanding evolving and I hope others can relate to that learning process and it helps them as well.
Again thanks.
Thank you for your videos. I’m just getting back into racing after years away from it. I also a leaf spring guy. Cut my teeth running Camaros in Northern California. Dirt racing has changed a lot since then. Back then the tires were Lewis and Clark retreads. I’m learning all over again, especially since I’m trying to set up a modified. Those bar cars are a whole different animal
Glad to hear it Matt and hope it goes well for you. And thanks so much for watching our channel! I hope you find some of the episodes helpful.
Thanks !! That was interesting....
appreciate it sir, Just made the one video like that out of all of them.
So very true!
Steve's going back and hitting some of my first videos :)
Appreciate ya
Yes sir
Thank you for the videos and it's helpful when you mention about turning right as that's the way our formula race in the UK as our cars are right hand drive.
Thats Awesome David, thanks for watching.
Sorry to bother you but do you have any advice on using street tyres? We run on both shale and tarmac and it seems like a dark art trying to sort tyre pressure and stuff out. We don't get to practice before racing. Unless you pay to go practice and our formula is a contact sport so suspension gets bent and it's hard to tell what has worked. Thank you
I ran radials earlier in my career and have a LITTLE BIT of knowledge.
Strictly have to get stagger by using different tire sizes. The steel belts don't give.
You need to look at buying an temp gage to dial in your air psi. It doesn't have to be fancy to get close. www.harborfreight.com/121-infrared-laser-thermometer-63985.html
If you are 5 degrees or more hot in the center of the tread compared to the edges go less psi. If its 5 degrees or more less then go more psi. Have a buddy put the temp gage in their pocket and do it As soon as possible when coming off a speed lap. I have taken it with me and gone to the infield post race just to get good readings and see where I am at.
Thank you for the reply will try that. Do you sleep thought it would be middle of the night over there it's 6pm here. I was worried using a tyre heat gun as I didn't know if running camber or toe would make the edge of the tyre hotter. And everything I've read said equal ( going be fun trying to sneak the use of a heat gun)
Just 6 hours difference.
As for camber, yes if the outside or inside is very different then you are way off on Camber. I just average the two edges. For example, if I was at 140f outside 135f inside i would call that 137.5. Typically a radial will hold the shape at higher psi but will cup like a bias if too low. So my gut says you are looking to find that perfect lowest spot where the centers of the tires isnt running colder.
Keep in mind , you are outside my expertise and these are just my thoughts on what I'd try
Get feed back about helping others to get started. I for one will even help someone that is beating me on the track to fix there car if it got something wrong with it during a heat race my school of thought is I'm not beating the better car or drive if there not out there running with me . I'm pretty new to it and still have a ton to learn but I can learn from the better car buy seeing the way he or she is driving and I feel that has helped me two improve
I sure agree with this too! It makes me think of a night a couple years ago when a fellow racer was having issues with his car ignition and couldn't run the feature. I pulled out my spare dizzy and took it too them and they looked at me like I was crazy when I said "let's get busy, where's the timing light!". They beat me that night. . . . But I gain SO MUCH MORE in satisfaction of seeing somebody else have a terrible night turn around and be great and also made some good friends for life even though I race hard against them.
So yes, I agree.
I enjoy your video
Thank you sir!
Also could you make a detailed list of the stuff you used for your tire spinner would help me out alot thanks for the information you are providing
I also made one up similar. Go to my channel and look at the videos I did there’s several then get back with me and I can also help you with materials
I looked back at my amazon history and copied the links. Some of these items are higher now. You have to shop around in there.

@@DIRTRACELIFE mine I got a gear reduction motor off eBay. The engine stand was an old one our group had several
Hey there, stumbled onto your channel and have been working my way through the series a video at a time. I do 90% of my own work (only thing I don't do is build motors) and I've been looking for educational videos just like this. I feel the same way about helping with what I know and try to do the same out here in California, been racing Hobby Stock for 9 years now and we've got the class pretty big now at Marysville Raceway. Also raced at Silver Dollar Speedway, Orland Raceway, Placerville Speedway, American Valley Speedway, Diamond Mountain Speedway, there's actually a lot of tracks in NorCal believe it or not. I live in Oregon now, will probably race Street Stock there next season but also contemplating moving out your way so I've been trying to educate myself on how y'all do it out there. One of my buddies moved to Paris, TN and raced a Factory Stock at Camden Speedway this year and loves it. I'll wrap this story up by saying that I've known Cherezian since he started racing and he's the real deal, cool to see you guys promoting each other and whatnot.
Thanks for reaching out Shannon! I guarantee you I probably either know or at least have watched your friend race at Camden. Glad you are enjoying the videos and stay tuned.
@@DIRTRACELIFE Skidmore, #33 I believe. Thanks for the reply.
Also if you want to run the heavy and rough tracks you need to come out my way. Here in northern california all the tracks are usually hooked up but rougher than sh**
I'd love it but you can bet I'd be putting some steel leafs on in place of my camaro's composites before I tried some of the stuff I see you race on in your videos.
th-cam.com/video/cQoiuhQlrug/w-d-xo.html
@@DIRTRACELIFE hey that was actually a dry and somewhat smooth track for around here! We have a guy running composite leafs around here and he absolutely dominates on a hooked up track.
Late to the party here, but I remember when I first started racing in 2008 I was 20 I bought a 76 el Camino out of a river bottom that was already a dirt car from the 80s for next to nothing.. my second time on track was a practice night and I had never ran around the track super wet. First turn I slid up and hit the wall and broke the right rear axle.. I remember getting wreckered to my trailer and then my brother and I fighting for an hour trying to get the car on the trailer with a floor jack and backing the trailer under it etc.. all while all the local guys stood by their cars about 50ft away pointing and laughing and enjoying the show.. not one person offered to help load the car or offer me advice on what I did wrong or how to improve in the future.. I didn’t stop racing but I definitely had a chip on my shoulder towards those guys for years.. eventually I earned their respect but none of them ever offered any help.
Been there, for me it was buying a 76 monte for $800 and going to practice day at a track with the tires that were on the car sitting in the yard for the last ten years. I set those four 235/75/15s on the car all at 30 psi. What a catastrophe.
I made sure the class they called "Slow Street" lived up to its name!
@@DIRTRACELIFE haha that’s funny, I ran on the old tires too they were old cracked up American racers. Had to air them up when I got to the track cause they went down on the haul over.
Belt sander makes sense
I am using the belt sander in the shop and now I am using a wood shaper head on a grinder at the track. (It was too much drama when I broke a belt at the track and REALLY needed to get done in the next few minutes)
Great videos, thanks! Did you make that tire machine out of an engine stand?
Yes sir, that was a Harbor Freight stand.
@@DIRTRACELIFE That's awesome. Can you share any details on how to build it, I'm trying to figure out an in expensive solution. I'm racing Factory Stock in Texas. Thanks
No problem Sonny, here is the link to a facebook post I made with much more details. And thank you for watching our channel!

Jason any Camaro or Firebirds around your neck of the woods I'm up in the Chicago area and if you find one it's either a mint ride or just a total rusted out piece thanx
When I was searching for frames last fall on FB marketplace I kept running across camaro front stubs. Apparently people were smart enough to at least pull those off before crushing the rest. But yeah, getting rare.
I never knew some use asphalt pull offs. My area is either H500 or American Racers
Some tracks I visit are "either/or" and some are just one of them. I switch back and forth according to where we go and what class we want to run.
Thanks for the feedback and watching.
I'm really enjoying your videos. There is so much knowledge in them that it's hard not to listen. Keep up the great work. Looking forward to see the new car being built and hitting the track
Can I get a video or pictures explaining this tire prep stand please I need to make me one
I have it on facebook with some details to help. Here is the link.
That is the biggest problem with racing... nobody will help anybody (unless they're family or good buddies) around here and I feel its probably that way in many places. I agree with you its not good for the long term health of the sport.
My fear isnt being slow in the beginning and trying to learn to get better... its wasting time and money in the beginning for no reason doing or not doing things I have no idea about. Its frustrating.
I think next to winning, playing with numbers and tracking and comparing numbers and information is the second best part of racing. Experimenting with ideas probably third.
I just dont wanna end up sucking for no other reason than I just didnt know the things other racers consider the plain ol "basics"... wasting time and money. Idk, I needed to rant a bit I reckon.
WB3, you have the right mindset to sustain long term improvements in your racing program. I understand why teams have the need to be very secretive but I too get very frustrated with those who act like wolves in sheep's clothing and mislead new racers right at the moment when they need good direction. It's overwhelming for new racers to figure out how to break into the sport and the last thing we should do is run them off with silly games. I appreciate your thoughts.
Thanks. It's all good, I just needed to vent a bit that night.
Just curious I noticed late model steer tires last night and the are grooved from the inside track up. / Is that different from what you do or did I just get it backwards ? 😂🤦🏻♂️
The angle should be the same as what I do but I'm not sure what tire and then some may be cutting backwards grooves for some reason that works. Since all my street stock tires may be rotated front to back I make sure to put left hand turn traction angles in them all.
This may sound stupid but it cuz I'm an asphalt guy but why don't you take a plastic drum or something to that size of the tire and cut a gig of Grove patern in it so you can slid it on and mark it out and cut it. 🤔
I think that has merit. Maybe a 2 inch wide band from a drum and then notch it every 2 inches. I hmmmm... i think I got a plastic barrel around here.....
:)
Just thinking outside the box brother
According to hoosier, front tire should be grooved from the front outside to the back inside.
They have given me some good advice on some items.
Grooving however is different per tire carcass and car class application. Hoosier has no recommendations for grooving a used asphalt tire for dirt because its simply is not a dirt tire. Their suggestions for grooving are regarding late model dirt tires that already have a tread pattern molded in and is suggesting additional patterns you can add depending on where the tire is used on the car and track conditions.
Most Hoosier asphalt tires brand new have only 6/32 of tread, where you finding tires with more than that?
I have a friend who brings them down from Wisconsin end of season. My last load I bought was in 2020. On the 3035s and 3045s pretty much everything he had always had at least five or six thirtseconds but I did very well at digging several out that had eight thirtyseconds. It probably differs according to tire model but no issue at all on those 3035s and 3045s.
As hard as tires are to get now though. . . . Shoot everyone probably runs them to the cords!
Can u redo hoosier 970s as well
Shawn, I've never grooved a 970 but since its just an asphalt tire for an 8 inch wheel instead of 10 I don't see why it would be an issue. Should groove great provided there's some rubber left to cut.
@@DIRTRACELIFE I race asphalt... is it bad to regroove for asphalt an would a guys still benefit from it. Thanks for the quick reply ...
Sorry Shawn but I my experience so far has just been on Dirt and grooving up used asphalt tires for running on dirt. I love all circle track racing but all my experience is on dirt so I sure don't want to mislead you about tires. Thank you for watching my channel.
That angle is incorrect at 29 minutes mark. Once the tire rotates over to the contact patch it is backwards from what you want. When growing on top the Grove needs to go from left rear on inner corner to right front on outside of tire.
You described what it needs to be on bottom touching the ground. Up top of course you are looking at it reversed.
@DIRTRACELIFE no, when it rolls over to the bottom I want it to give the tire a bitting edge . The way you are doing it once the tire rolls over to the contact patch it will just be a line on the ground that goes from the RF to the LR. If you do it my way the tire has a biting edge on the ground that is gripping during cornering. I have been over it on a lift many times and had to show people
ok
Could u take a some pictures of the tire machine without a tire in it?
Sorry for the delay Landon. I can do that. I'll do something and put it on the Facebook page tomorrow. Thanks
@@DIRTRACELIFE I cannot find ur fb is it the same as your TH-cam page
I uploaded some details Landon. Here's the link to the FB post and thanks for watching!
