Default BottleCaps with Yokohama A032R for Auto-x - Thoughts?

I'm thinking about getting a set of caps for auto-x. What do you guys think about getting a set of these tires in 195/60HR14?



My next question...

They give you 3 different tires to choose from in the size I mentioned above:

Heat Cycled
Shaved 4/32nds
S-Compound

Which one of those would be best?

Thanks guys!

i would go with a little wider tire, maybe a 205, i had those on for awhile and they had great traction, too bad they were 50000mile tires and i wore them out in about 20000 i had fun doin it though just my 2 cents...

The Yokohamas are not a good autocross tire, and 14" Bottlecaps are not a good autocross size. There are larger, wider, grippier, faster autocross tires you can get that'll make you a lot quicker than Yokos on Bottlecaps, and it depends on a lot of things like what organization you'll be running with, what class your car will be in, and if you want to buy better wheels to go with your better tires.

I have to agree with Randy, folks around here don't have much good to say about those yoko's for auto-x... If your set on going the bottlecap route, I still have 4 with fresh powder coat and 2 have Kumho's mounted with only 1 autox day on them... Just incase your in the market... If not, ignore everything except the first sentence...

True , those Yoko's might not be the best choice .
Plus those 225/50 street tires would give you more grip than the Yokos in a 195/60 .
on the bottlecaps you'd want to run at least a 205/60 but you would be doping yourself a huge favor by using a set of 15's for auto-x .

Thanks guys!

Tire choice is all about how competitive you want to be and how much money you want to spend.

Regardless of tire brand or size heat cycling will make your wallet lighter immediately, but provide longer life to tires because they will be harder and consequently quite possibly slower. Shaving supposedly makes the tire last longer by eliminating some of the thread squirm that is present with full thread tire. Likewise on the wallet/tire life/performance relationship.

There are H- and S- compounds for this Yoko. "S" is for "Soft" and "H" is (you guessed it) for "H" hard compounds. For autocross "S" will be better due to increased traction on lighter cars according to Yokohama.

Nice thing about these Yokos is that their contigency program, AFAIK covers more events than Hoosier or Kumho.

If you want the best tire for autocross you'll have to choose between Kumho Ecsta V710 or Hoosier A3SO4 based on last year results. Some people were convinced that Kumho was actually faster than Hoosier after they came out with updated design.

As far as size Randy is correct that 195 would be rather narrow. 225 would be more appropriate. If you aren't going to lower your car by much or run on really bumpy lots you can get away with 225s on 15x8 rims. Worst case you'll have to roll the inside lips a little.

Thanks for all the input, guys.

I'm really liking those Hoosier A3SO4s.



What do you think is the widest tire that you could get away with on IE stage 3 race springs and a fender roll? (think ideal offset)

The fastest autocross tire isn't necessarily the best autocross tire

If you're going to be casually autocrossing mostly for fun the Falken Azenis is a sturdy and surprisingly fast autocross tire. It's cheap and lasts longer than any other popular autocross tire.

But it really boils down to which organization you're going to be autocrossing with (BMW CCA or SCCA) and exactly which class your car will be in. Whatever class you run in, there will be at least one good tire choice and you should go with that. I've run Hoosiers and Victoracers, but the most fun tire is the Falken Azenis even though it's not nearly as fast as the R-compounds. I bumped down from DSP to STX just so i could run this tire and i'm having a blast on em. Plus i can leave the tires on all year instead of changing from streets to race tires every weekend.

So will this be with BMW CCA or SCCA? And if it's both, which one do you want to be the most compeitive in?

And what class will the car be in? Stock, STX, or Street Prepared etc?
