What tires do you use for racing?
I'm in the market for a set of tires for tracking and autocrossing. But first I'm just curious as to what some of you guys use, or if you can reccommend anything.
I dont know much about tires or about which ones would probably suit me best, so any help is appreciated.
Thanks.![Thumbs Up](https://www.northamericanmotoring.com/forums/images/smilies/thumb-up.gif)
btw, these tires will be used on track only, not on the street.

Get them here and tell Bryan I sent you!
This is a great handling and about the longest lasting R compound tire out there. VERY LIGHT also.

New to racing ... What does shaving the tire do for you ? Wouldn't it wear faster?
Here is a visual on the shaved results : lower right of page:

Here is some more Data I found here: http://www.rogerkrausracing.com/toyoRa1.html
It is recommended to shave the tires to 3/32" to 4/32" for serious competition use

Shaving to less than 3/32" will increase performance but reduce tire life
Hot pressures in competition will run from a minimum of 36# hot to a max of 46# hot, 40# hot is a good starting point
Running 2# to 4# higher pressures in the front tires will reduce understeer in most cases
Remember that the tires will build up pressure in competition. Usual pressure build up is from 3# to 9#, this must be taken in account when setting cold pressures

im going with rt615 next season.. hopefully they'd have 215/45-16 then

Most people suggest not getting r-compounds as your first racing tire because it hides a lot of mistakes a novice driver makes. I would say get a grippy street tire, get some experience and move up later.
Thanks to those who have posted so far. Others, keep em coming!

They rate tires based on tread ?compound? I have lost the right word. Anyway a street tire has to have a tread compound of about 200. While a racing tire is less that 200. R-compounds can be as low as 50.
Also, street tires are more predictable, they will give you a heads up on when they are about to let go.

Toyo RA1s are DOT street legal tires that many do use on the street.

I have heard decent stuff about the Kumho MX's. They are just regualr street tires (max performance summer), but seem to have great tendencies. They will let you know when they are about to break loose, unlike in many R-compounds that just let go without much warning. Personally, i would go with some high performance street rubber before stepping up if this is your first time to the track. After a season under your belt (and the tires are all worn out), get some R-compounds. I've had great luck with the Nitto 555rII on my Inifiniti. Unfortunately, they only come in 275-40-17 which really won't help you much. I've heard they started making some other sizes. Of course, you can go wit hthe old stand by Kumho Victoracer. A lot of people around here seem to use them with great results.

I have used Kumho V700 Victoracers (205-50-15) (on many cars including the Mini) and Kumho V710's (215-40-16) (only driven these on my mini). I have never tracked the 710's, I save them for autocross. They are fantastic autocross tires. This is THE tire to run if you want to be fast on the autocross course.
The Victoracer is a great tire, too. It's pretty cheap and takes lots of abuse. They don't make a good 16" size in the Victoracer for the Mini. These are probably a good choice if you also plan on doing track days on your sticky tires.
By the way, the SCCA currently draws the line between a "street tire" and an "r compound tire" at a treadwear rating of 140. Last I saw, the ST* rules also had a list of excluded tires, too, in addition to the treadwear rule.
For stock autocross classes in the SCCA (as well as street prepared and probably street mod), you have to have a DOT approved tire but can use any treadwear rating. For Prepared and Modified, you can use non-DOT slicks.
