Tire prep basics - Part 1

As promised, I am going to talk a bit about the very important subject of tire prep. I’ve decided to divide this subject into two videos, for the reason that, most big events worldwide today are run with a spec additive rule, which limits the opportunity to “play” with tire prep. And thus, I will make separate video, to be released next week, which offers some guidelines for events where there is an “open additive” rule. Today, I’m going to share some basics for racing where there is a spec additive rule. Enjoy!
The tire additive featured in this video is the HUDY Tire Gripper Red. A very strong additive which works well on both carpet and asphalt. Part number 106261.

Thanks for including the asphalt racing comments, really useful here in Cape Town!

Great information. Thanks for sharing

Good advice here, thanks👍

Hi alexander i love your vids and your car please can you tell me a good gearing to start with on a hotbodies cyclone i'm running 17.5 blinky and on a u.k tarmac track with twisty turns i'd be very grateful for any help

[@hagberg]

4.1 FDR and 46 endbell timing. That's on the Hobbywing G3R

[@billimono4480]

how long do you cook the tires? and what temperature, for outdoor tracks? any recommendation for a good starting place?

[@hagberg]

10 minutes at 60 degrees C is a good starting point!

[@yapjason8546]

Hi Alex , after I cook my tires for 10 min should I wipe the excess additive away ?

[@hagberg]

Yes! You should wipe off the excess additive before going to the track!

Hello, you clean your tires before à run, not after? Am I right?
Thanks for your videos

[@hagberg]

Correct, I clean before but not after !

[@maximedurand2214]

@@hagberg thanks, I was wrong, I was doing the opposite 😅

[@starlinggibson4117]

Hello, I just ordered the HUDY red gripper and plan to run on low traction asphalt, is this a Oil bar traction compound, than you

[@hagberg]

The Red one is a carpet additive (not oil based). For asphalt, I recommend the HUDY Asphalt additive, part number 106262.

[@starlinggibson4117]

@@hagberg Is this they best HUDY option for next to nothing Asphalt traction

[@hagberg]

@@starlinggibson4117 yes!

How can we reduce “ring of death”?

[@hagberg]

There's not a whole lot you can do which will help. If the tire is soft enough, and racing speeds are high enough, there will be inevitable tire wear. But, if your main goal is to try and reduce/delay the ring of death, try looking into the following solutions:
Lower roll center
Softer springs and/or shock oil
Less camber gain, especially in front
Less static camber
More chassis flex
Less aggressive tire additive (more oil content)
Less tire warming
Shorter additive timing

@@hagberg Thanks for info. Will try it out. Currently get around 25 packs before it got torn on Rush 36X at SACC track KL. Running 13.5 blinky with FDR 3.7x. Camber -1. 😁

[@HL-OOI]

ROD not visible anymore after lowering roll center, traction compound and tire warming 🤣 camber set back to -2..
