I want to run 275-45 on a 18x10.5 would it be too meaty i have a 350z doing 700hp so i need meaty tires
@@that350zdude6 the offset is definitely needed to know if they'll fit well. I have 265/35R18s on 18x9.5+40 on my BRZ and the tires fit very square, so a 275 on a 10.5 would probably be closer to a small stretch, but different tire manufacturers fit differently for a given nominal size. I know the Nismo 370Z has 285 width tires on the back from factory, so taking an uneducated guess yours should fit
Chris Smedley they are 18x10.5 +22 offset I really don’t know much about tires
315/35r20 on a 10 is an absolute winner
*Normal stance stretches*
*205/40* 8.5" wheel
*215/35* 9.5" wheel
*225/40* 10.5 wheel
I run a 195/45 on a 9
Ratchet FA5 Tyre stretch guide does
195/45 on 15x8 (pretty normal on miatas at least)
Jordan FitCarGuy im trinna run 165/45 on 9.5 so im trinna get an idea of what it might look like
I have 16x9 wheels

I was running a 215/40/17 on my 17x10.5 on my 2007 Volkswagen Rabbit and I never had any problems 👌
Good stuff man. We appreciate all your hard work and knowledge.
🙏🏼❤️
*I'm not much of a stance or tire stretching guy, but I love the round tire look!*
I am get new mags 18 8.5 but tyres
225/45R18 9.5 w and will that be stretch my other mags 18 9.5w will that one be stretch want to know
I dont like stance either, but ima have to stretch my wheels, since i bought them a bit small by accident, not to much tho.
Tom Kevin You can't stretch wheels only tires.
Me too
“But officer alex from fitment industries told me how to do it”
😂😂
Lol that's so funny
Where does a 215/35/19x9.5 +22 set up fall under??
If you guys will make a “stretch/meaty calculator” in your website; that would be great! But nice video, this was helpful! I’m on the meaty side tho. But stage 1 stretch looks tempting:)
willtheyfit.com annnnnnnd there ya go
martin villaflor there is a webiste called tyrestretch.com that you can find all the different size stretches on
Jeremey Perez cool! Thanks for the tip. I just wanted to share some insights to help Fitment industries. After all it can help their customers as well rather than having their customers to use other websites or competitors.
ir4kk thanks!
You must be new to the internet .. you don’t know google?
Exactly the video I’ve been waiting for...love you guys💜
before watching this video i was a little nervous about how my 225/40 18s came out on my 18x9.5s but now i feel better with only being at a stage 1 setup. it looks great but im glad there is minimal safety concerns (or so i hope lol)
Awesome work bro, thanks for your time and knowledge 💯
This is perfect! This video helped me understand tire sizing
🙏🏼
2 things I found after running stretched tire for over 40k miles.
Some tires do not stretch equally on both sides.
Inside vs outside will look different depending on how the sidewall flexes.
Also
All your worries of debeading a tire goes away after you powder coat the wheels. Makes the tire fit a lot tighter. In fact, so tight, I'd have trouble getting them off with a shop tire machine while installing new tires.
Most informative FI vid thus far IMO. Thank you!
Thank you! 🙏🏼
If fitment industries themselves give a disclaimer to begin with, it's probably a stupid thing to do
Peter Chhan all the fun things in life come with a disclaimer.
No such thing as "stages" they just make their own rulebook.
@@ssholeEater No sir, you're wrong: my wife did not come with a disclaimer. All spouses arrive in "as is" condition, and your mileage will definitely vary.
As for the "stretched" tire thing... it's bad practice [and I hate it], but not as dangerous to roadworthiness as putting in wheel spacers along side lowering springs - suspension parts start begging to break when people do that. I can't think of one reason to have wide rims in search of less contact patch by using an undersize tire - just buy smaller rims.
If youre using wheel spacer you should be using longer studs
no
Dude I was ready for some crazy ass equation, thank you...
A very interesting video indeed. Stretching isn't my thing at all, but your explanations of stages and the technical aspects were really interesting.
Been waiting for this for a while. TY.
lmfaooo that disclaimer is why I love you guys
Never expected to see one of my clips on here. Thanks guys! 1:10
WetttMedia clean car
My summer tires are STAGE -3 (225/50 17x7.5) and I still watch these videos.
Thanks and learned more in this video than all my self-research...
Crazy how long tire stretching has been around for. My dad used to stretch the hell out of tires on a set of 15x12 wheels back in 94' on his Toyota pickup truck.
gabrielxhavok yeah in europe vw, bmw and opel guys have been doing it since the 80’s. it’s really nothing new lol
Old man stretch ain't nothing to mess with.
Low riders stretch trailer tires
thats that lowrider mini truck
Gabrelxhavok what size tires did your dad use on his 15x12's
GREAT VIDEO AND INFO!!! YOU SIR, ARE A GOD!!!!!
This is qhat i was looking for. Finally lol. I have stock tires 265/70r18 tires for my silverado. I went to a 18x10 rim. So im gonna be stretching just a little bit
I got 15 x 8 with 195 /50 15s and it’s a great look . Not too much stretch and I can still slam corners .
Sounds dope we would love to see it on our gallery! bit.ly/2Ma4oca 👍
Fitment Industries I was actually going to send a video and pics in . It’s not completely done yet but it’s nice and clean and has a ton of suspension work and some motor work . Trying to keep it jdm .
Fitment Industries so I keep trying to upload in add my ride but the site keeps kicking me off before it’s done uploading ? Any ideas what’s up with it ?
What a coincidence that y’all dropped this cause I was wondering what I was going to run on my next set up 😂
We are mind readers 😬👀😂
Video saved. This is good information...
Genius & Very Great Explanation, Thanks 🤗👍
My rule of thumb for stretching tires is to try not go with more than a 1/2" difference between the wheel width and tire width.
I have 20x8 I want stage 2 low profile look what size
@@tmoore4356 225/30 is the smallest you can get, or 215/40 but then the sidewall gets bigger. There are no 20" tiers small enough to streach on a 8" rim unfortinetely.
@XFOX1996 so it is a 20x8 rim and I want a stretch look so 225/30 what about 225/35 ?
@@tmoore4356 you can not get strech on 20×8, there are no tiers that small for 20", 20×9 is minumum if you want strech. Both 225/30 and 225/35 will be flush, 0% strech, only the sidewalls differs.
@@tmoore4356 you would have to get a custom 205/35/20 tier made for you to get a stage 2 looking strech on a 20×8.
I knew some real basics... but this is insane
Whoa I know the guy from the first video insert! It's an old video but I believe he still goes by the name of KEEK. Has a cool bagged Mk4 Golf nowadays :)
Very helpful, looks like im going stage 3 meat with the track setup (if it will fit) 17x9 with a 255/40/17 tire
245/45 in the front and 275/45 in the rear on an 18/9.5 square setup. Got very slight stretch on the front and looks meaty in the rears 👍
Sounds sick man you should upload your ride to our gallery! 🙌bit.ly/2Ma4oca
Shouldn't have any stretch on the front, must be the tyres your using.
@@paulythedropbear.3969 Yeah most likely. Nankang tires.
I have 215/45 tyres on 18" by 8" wheels, and they are almost a perfect fit. 225 would better though, the Goldilock zone for that wheel size. Buy wheels to suit the tyre size you want instead of just making them fit. Unless you are more interested in looks vs performance. If you prefer the former, then don't complain when you crash.
215/35r19 on a 19x9.5 haven't had any issues as long as I keep my psi about 45psi with -12 degrees of camber. Sidewall ridin!
Very helpful video thank you very much!
Came here for the comments section. Love the disclaimer at the beginning of the video.
6:50 perfectly timed for the ads. To cut in XD!
Thanks, my bmx is going to look sick on stretched tires😁👍
Cool I learned something new.I’m a tire expert now.
What would you say a 215/50 on an 8.5 wide wheel? I love the setup and it's still meaty but has a tad bit of stretch I feel
Its a bit of stretch not terrible if that is the look you are going for there might possibly be a chance of rubbing at turns as well! Have you checked out our online gallery? We have a super nice filter that allows you to find cars with the specs you are looking for check it out! ----> bit.ly/2NAR31I
Karate chop on articulate :)))...Man I've seen like stage 8 stretches in Japan lol
Great info.
I subscribed to this channel.. I don't regret it.
Thank you! 🙏🏼
I'm running a 225 35 on my 10.5 and a 235 35 on a 11.5
Fitment industry , I have 15x12's on a slammed F -150 and want to run a streched tire on my rim any tire size suggestions.
I've seen a lot of 225/40r18 on 18x9 wheels on your website and they are all quite stretched. I understand that 225mm = 8.8", but pictures show a much different reality.
He's an awesome teacher

Rolling on 245/45/20 is that consider a stage 1
Cause originally I was going to go with a 255/40/20 but tires do get more expensive.
Let me know if I have a proper setup.
there wouldn't be an issue with that!
That would be a meat stretch stage 1 i believe since it's a 10" wide wheel. You went one down in width and two up in aspect ration so one minus and two pluses
My stock wheel is 6.5 and I’m looking at a 7 wheel is that half inch a big deal or should it be perfectly fine?
I adore this channel
🙏🏼
This should be a requirement for graduation in high school math, Ged, sat's, the bar, mcat's, etc. Loved it!
I'm over here trying to get the big of a tire I can fit. 235/55 on a 6.5" wide wheel... I need road contact for traction. I would go wider but it starts to become jello when turning.
I see what you're saying it can get difficult figuring out what size tires you should get. You should check out our gallery when looking for the perfect fitment our website is designed for that! 🙌 bit.ly/2Ma4oca
What do you guys recommend for a "meaty" setup for 17x12s and 17x10s?
I would say maybe for a meaty set up a 315 / 35 but you can check out our online gallery to see what other people are running for a tire size with that setup on our gallery here! ----> bit.ly/2SfpuK6
On my C63 I've ran 305/35 on 19x10, a 275/25 on 20x10 (cracked a wheel), and a 285/30 on 20x10.5. Just got a set of bc forged 19x11 and deciding on tires right now
use a thicker aspect ratio , save your wheels use 40-45 series still a low profile i use 60 series.
Thank you for posting this.
I want 18x9.5 +38-+42 or 18x9 +33 wheels, but I don't want to go beyond a 245 tire width. Trying to be as close to stage 0. Which by the math is the perfect width for a 9.5 inch wheel.
But I've seen 245 40 18s in 9.5 appear stretched...on the OEM 8.5 wheel, that tire appears stage 0. In most people's setups it appears that a 265 35 tire is flush for 9.5 inch wheels...
k_wrx_ I’m running 245/40 on my RPF-1’s. 18x9.5+38, 2015 WRX. I took the tires from a 16 STi, I’ll be getting 255/35 soon

Oppps my 215/40 fell onto my 10.5 🙈
This was a very informative video but should have another disclaimer that changing the side wall and width of there tires there changing the rotation of there wheels which will throw the speedometer off on there vehicle if not done properly
Good suggestion man very good point! 🤟
Shorter tire height , better acceleration, speedometer will read fast.
Taller tire height,more top speed, speedometer will read slow.
Altering your tire height has the same effect as swapping the ring and pinion in the differential, and is cheaper.
It all makes sense now!!!!!!!
Here's an idea if you don't know what to call it just called at GS basically means a grip stretch which sounds pretty simple and it doesn't sound weird just use the term grip stretch cuz you stretching the tire but the same time you still have that strong grip
The geek voice suites you so well. sounds the way you look perfectly.
Giving stretch a “stage”
Hey Alex love the videos from FI. Keep it up, do u mind doing a video based on all those numbers eg 18x10.5 - noob to the rims game
Check out our sub channel Fitment Industries Garage! It is perfect for what you are looking for!
Oh hi!
Thanks guys, awesome vid!
PS: I'm also called Alex. Alexes rock.
You rock
We aren’t rolling fenders we are cutting them “next year tho”
How about a 215/70/15 on a 10" wheel
I wouldn't run extremely stretch but I do want a little bit just because I think it looks clean. I think meaty tire setups can look clean too but I have a stock fender Z and I also don't want to throw off the weight/speedo potentially by running fat tires.
I had 245/45/18 on my xxr 521 18×10" I liked the stretch I had. I'd do it again
also forgot to mention some tires look different than others my 275/35 nankang look more narrow than my 275/35 michelin which look more meaty.
kevin sanchez I think that’s where the previous video explaining what brands are best to stretch would come into play.
Yes Michelin are generally more of a meaty tire.
Yes, that's true. I've had some pirelli that were square and changed them to the same size from a different brand and those were a bit stretched.
Some of the 4 wheelin coal rollin trucks around here seem to have found the tire stretch calculator 🤔
Can you do a video on how to know what set up or know what off set of size wheels for cars
Aspect ration comes into it too!
My brain hurts. 🙃
Stage 2 for me I think lol, 235/40/19x10.5
stage 1
You’re mounting and balancing my setup again, second time buying a setup from you . This time I bought the now questions asked warranty. Does this cover my wheels even though I am stretched. Mounted and balanced by FI.
That is correct!
im running 205/45/17s on my 17x9s on my mk4 jetta with coilovers, it is mint
I apologize if this question sounds crazy I'm still learning. I understand you can stretch the width of a tire but can you stretch the diameter? My tire specs are 225/45/17. Can I stretch that on to an 18x8.5 wheel? If not, can I stretch it on to a 18x8 wheel? My tires are designed for 17x7 wheels but I really want an 18 inch wheel with a wider tire but nothing past 8.5. If anybody can help me with this I would appreciate it a lot. I'll even send a dollar to you on PayPal😂
Matt Parker not sure if i‘m using the right terminology. Not a native speaker.
You can’t put a 17 inch tire on an 18 inch wheel because the bead that keeps the tire on the wheel is partly made of steel. And steel won’t stretch.
So if you want to run an 18 inch wheel you will need new tires. In this case 225/40R18 (wich a run aswell). My wheels have a 7,5 inch width wich is basically this square look.
If I understood Alex right you could go up to 9 inch on this tire (for a stage 3 stretch) before you get problems with debeading
@@lucagrundmann9469 Thank you for making it clear to me. I will go with 17x8.5 wheels now. Do you have PayPal? I will send you that dollar no problem cause I really wanted to know 😂
Matt Parker it’s no Problem. Just make sure you get the right offset or you have to use spacers. Otherwise you‘ll hit your suspension with the wheel inside
@@lucagrundmann9469 I know about the offset but thanks dude
That's where u like living in Germany .... Not only all those inches and mm and stuff but the law going to it as well u dont need to think about an 205 / 40 on an 8,5 wheel cause our law says that 215/40 to an 8,5 '' wheel is the max + the fact that ur new tire size need's to match up with the old one so ur speedometer doesnt tell u an wrong number u are allowed to go 100 km/h when ur speedometer says ur going 104 km/h but u are only allowed to go 100 km/h when ur speedometer says ur going 99 km/h so law can get u in trouble thinking about tire sizes as well
You can spie check it with your phone.
Its true Alex, this do common that the installer very often forgetting to inform the customer that stretching is outside the waranty of the tire..
This is a dope video
2:44 *Me trying to explain how close the race was to my friends
im a stage 2 meaty
I see you guys are still answering comments on this even 4 years later, that's crazy.
I've got a question for tires with meatier sidewalls like race slicks. So for example I've got a set of 295/35R15 Hoosier R7 Autocross tires, and I'm trying to pick between 15x13 or 15x14 wheels. With the 14" barrel I'd be at a Stage 4 stretch (show car, goes on a trailer, don't worry about it) would that be different since it's a slick and they tend to run a little wider than street tires?
And thanks for the video and the gallery, you guys have saved me a lot of time researching setups in the past.
The only thing with the bigger sidewall is you may run into fitment/clearance issues depending on your setup
love this

How am i running 215-35-18? It's max stretched out tough" 🤣
The integration of the meme at 0:55 killed me LOL
I have a 18 x 7 wheel currently and I just bought new enkei wheels that are 18 x 8.5. I’m keeping my recently bought tires that are 225/40/18. Would this be consider a “stage one” stretch? I’m not into stretching tires but I’m wondering if my tires would work (they are stated to work with 7.5-9 widths)
You explained how and now you should explain why...
There is no why. At least no positive why.
soon people gonna be putting motorcycle tires on their 17x10s lmao
Hey, at least with bike tyres you don't have to worry about camber!
@@SoulTouchMusic93 LOL

I have a 15"x9" rim I'm looking for a stage 1 or 2 stretch and help on what size tires I will need
Didn’t know there was supposed to be calculations for this, I just bought 235/35 for an 11j and hoped it would work
🤷♂️😂
🤦😭 sent!
Guess I have stage 1 meaty
So I would be a stage 4? 215/35 18 on a 10.5?

Would I be able to run a 265/70 (stock 06 Silverado 1500) on a 17x8 (the stock rim is 17/7) so the stretch shouldn’t be that big of a difference right?
Thank you!
DUDE 315/30? on a 19x14? WHO TF IS RUNNING THAT 🤣🤣

Exactly, it's only for show, or to be a cheap ass. Not for performance.
What about a 265/35/22 on a 10.5 wide is that a stage 1 stretch or a straight up and down sidewall
