I plan on using my Stock set of 18" wheels on my brembo G. What tires & sizes should I get that are readily available. Toyo's, Hoosiers, Kuhmo, BFG ????

Thanks for the help.

 

If you are staying in BS I believe you have to get the exact same size tires.

 

I can use ANY size tire on the Stock Rim Size. I was planning on using a 245/40-18 or a 255/35-18. I just don't know what tires ppl are using on the 18" x 8" wheels.

 

Actually, per SCCA rule book, you MUST stay in STOCK sizes or optional sizes that come with the car for that year. You can not upgrade the wheel size, go wider, or anything with the wheel or TIRE. It must be equal to the stock sizes.

Here is a tire that is becoming very popular in the scca world...

Very sticky tire.

 

Too bad that it doesn't come in an 18" diameter.

 

As per 2005 SCCA AutoX Rulebook page 64 and I quote:
Tire must fit the allowable wheels and fender wells without modification.

 

Dunlop AutoX Tires

Can I use these 255/35-18 all the way around on stock 18"x8" wheels?

 

I believe the proper size on a 8" wide wheel is 245mm, a 255mm will fit but it was intended for 8.5" wide wheels.

 

I'm running 275's on my race 17's, so I think you'll be ok with the 255's on the 8"

As for staying in BS, I think they're right. However, it doesn't sound like you care what class you're in...
