In my relatively short experience with Auto-x, I have realized that one of the first things you do for being competitive is to have a good set of tires.

In street tire classes, a set of Falken Azenis had made a huge difference for me from regular street tires. Now its time to move on to R compound tires and see what I am capable of. Car is a 99 Integra GSR running on 400 Front and 450 RearGC's and Koni yellows. Type-R rear sway bar, corner weighed, typical IHE mods etc


1) What's the best tire for Auto-x (name, size etc) => Considering price and performance, also considering that I am just starting to drive on R comps etc

2) I will be using a comparatively light weight 15x7 wheel. Is this a good wheel size?

 

what class you running...

if u really wanna competitive.. assuming your running DSP i would run the smallest wheel that fits over your brakes i think lensos fit... and for tire
kumho v710s would be a good choice...
but Hoosier a6 is the tire to have

 

Saying the A6 is the tire to have is a bit of a stretch. There were many winners with Kumho's. Both tires have their advantages and disadvantages.

I have a set of Lenso's with 710's on them for sale. Ran them this last year and they are a very good tire. The only reason I'm selling is because I want to go with better brakes and do more track days.

13's are not the only choice of course. 225 45 15 Hoosiers will get you a wide tire and the gearing will remain very close to stock.

 

ya well i just wanted to get the ball rolling haha

It worked...

 

Yes, I will be running in DSP
Will the 225 45 15 Hoosiers fit on a 15x7 wheel? In that case no need for a new set of Lenso wheels

 

V710's and a garden sprayer.

They are cheaper, tend to last longer, and seem to be less sensitive to tire pressures and overdriving than the HooHoo's.

 

It's not the best set up obviously but yes they will fit.

 

What is the best set up, if I want to continue using the stock brakes?

Also, for a 15" wheel, I think the V710's are the best option available?

 

So far the 285 30 18 is the best set up but for us folks that can't afford a 3k set of wheels and tires...just use what you have as long as it's safe. If you could get a 8" or a 8.5" that tire would do a bit better but if you have a 7" just use it and have fun.

Too bad too, I think you just missed out on the 15x8 sale Heeltoe was having.

That's debatable. This may have been THE setup were the Nationals still on Forbes field concrete and in early September. With the new low-grip HPT surface and the fact that the event has been moved to the last week of September, getting any heat into those pavement rollers may become a huge issue. I think you may see more and more competitors moving to SMALLER tires in the future. Hell i couldnt get any heat into the 215-50-13 V710s at the Nationals. Ok, it was cooler than normal for that time of year and my car was like 1650lbs, but still...

Now, if your local site is super grippy concrete, by all means go ahead and knock your self (or your wallet) out and get the monster tires.

 

The winner in DSP was on 285 30 18's this last year. I don't see it changing any time soon, even with the surface change. Plus once the surface wears some, the slick like tar will go away more and more.

In terms of rotational mass it does slow our cars down but the overall increase of traction in the corners is so much more theres no question about it.

Our local group runs on pavement. My tires are over heated after the first run (215 50 13 710's). The pavement is also several years old.

But we shall see.

1. For an introduction to R-compounds you might want to look at 205/50-15 Nitto NT-01's... they are streetable, have good wear characteristics, and hold up well on track as well as at autocrosses (no need to spray them with water.) Makes no sense to jump into DOT R with the Kumho's / Hoosier's tire life will be half of the Nitto for not that much of a difference... start off with a less expensive and longer lasting tire to get your moneys worth on the first set.

2. Wheel width to run is determined by tire size choice and suspension setup preferences. I would just run the same size you've been running on the street tires to get a direct comparison on the capability differences of DOT-R tires.

ummm winner of DSP is a BMW...

how does that... relate to his integra?

 

Because Integrs are also using 285 30 18's and doing very well...that's how.

 

For DSP it would seem like you want to go big or go small. Either the 18" wide foot print or a 225/x/13. Going with a 13" wheel seems to make the most sense - light, low rotational mass, lowers the car 1".

But if you want to stay with 15" wheels then the 225/45/15 Hoosier A6 will fit on a 15x7 rim easy (I put the same tire on my 15x6 rims. Keep in mind that clearance to the rear LTA can be an issue. You probably have to roll fenders and go with smaller offset rims to fit.
