Autocross Tires

No sizes that wide and on Nationals they looked much worse. There are people that like them but they seem little off pace of RE-71Rs.

With 19" tires that are that wide, there are no top autocross tires available. For Rivals, he would have to go down to 18". Widest RE is 305 if I am not mistaken.

ah, yea, the rim size would be an issue then. i know 71s and rivals owned nats

Agreed. The 285/325 is a great staggered setup for street oriented enthusiasts, but the lack of worthy track compounds is precisely why we recommend 18" and 19" square fitments for track/AutoX use. The ability to rotate wheels and tires effectively, while mitigating the cars tendency to understeer really makes it an attractive option.

Some good extreme summer and r-compound options depending on desired tire size:

18x10" ET43 square
- 275/40-18 RE-71R, NT01, R888
- 285/35-18 RS-4
- 295/30-18 R888R, Trofeo R, Pilot Sport Cup2

18x11" ET52 square
- 295/30-18 R888R, Trofeo R, Pilot Sport Cup2
- 305/35-18 NT01, R888
- 315/30-18 Rival S, NT01, R888R

19x10" ET40 square
- 285/35-19 NT01, Pilot Sport Cup2
- 295/30-19 Pilot Sport Cup2

19x11" ET52 square
- 295/30-19 Pilot Sport Cup2
- 305/30-19 RE-71R, NT01, Pilot Sport Cup2

That last one is what you want ;) 25mm spacer up front.

Thats been the ticket for many of our customers. Perfect for the GT350 as well

Lots of good feedback on the MPSS4 tires. Costco also has an instant $70 rebate and 1 cent per tire installation going on for Michelins.

Is this for "Stock sizes" though? Last time I went to buy tires (MPSS) from costco their promotion were only for "stock sizes". Annoying.

What specs are the wheels brotha?

The MPS4S is getting great feedback

I have used the RE-11 they were great as well. Personally the best is the RE71R tire

So right now I'm on the RE-71R ticket. The top 2 guys in my class are running them (Actually used to be 1 until another guy got the RE-71R's).
Although the MP4S (and the old MPSS) are good tires, aren't they more street tires and the RE's more dedicated sport tires? Case in point being the
200 Treadwear of the RE's and the MPSS being 300? Not too sure what the MP4S is though...

If you are looking for a tire that can handle repetitive lapping, providing you with superior grip without getting greasy or
deteriorating, I would urge you to explore other tire options. While the RE-11 and PS4S are fantastic tires for the street and spirited driving, there are much
better options for HPDE's. Assuming you want to stick with Extreme Summer tires, I would suggest Bridgestone RE71R, Hankook RS-4, Dunlop Star Spec ZII,
Yokohama AD08R or the BFG Rival S.

As Paul mentioned, we would need to know what your wheel spec's are and what your desired tire size is? Tire availability changes quite a bit from size to size.

Also, do you have adjustable camber plates installed?

Great insight Ryan. How would The Hankook, Dunlops, Yoko's and Rivals all differ each other and the Bridgestones? Thanks in advance.

Harvey the hurricane made me replace my rear tires early & I found Bridgestone S-04 pole position's for $195.00 that have 280 treadwear rating. Price wasn't great but I was in a bind. They rated 2nd behind Michelin in 2013 Car & Driver testing. I like them for the twisty's.Sizes I don't know?

So the whole questions comes to how serious OP is about autocross. All the tires you proposed except REs are not street class legal, so if someone is really serious, would be dumb to not go Hoosiers - they're not exactly daily driver tires either.

MPSS / S04 and other proposals are nice daily driver tires but not a top autocross tire and not even close.

Generally for a serious autocrosser, tire choice and availability determines wheel size (+ classing obviously but not the case here sounds like).

I am thinking a 2nd set of wheels might get involved to have a street set and a track set. Thanks for all the info!

Honestly, that is the only way to do it. Good call.

I intended to get a second set of wheels for autocross, but came across a crackhead deal on 20's. Now I can't get the tires I wan't in 20's either. You will definately be better off matching your wheels and tires before just jumping in.

Not sure what kind of deal you got, but there isn't much out there that beats the 19x11 SVE GT350 wheels. I got mine for 875.

Keep in mind there isn't a governing body to regulate tire manufactures and their treadwear claims. The RE-71 is absolutely the fastest tire amongst the few mentioned in your post, however they also wear out much quicker than the rest. On that note, I have found that the RE-71R with a 200twr wears quicker than the NT01's, and those are considered an r-compound with a 100twr.

It really comes down to personal preferences, desired longevity, driving styles, location/weather etc. If performance/lap time is top of mind or you are competing in a class with a mandatory twr of 180+ or 200+, look no further than the RE-71R as others have mentioned. All of the top finishers will be on them. If you would like fantastic performance with more longevity, the Hankook RS-3 (now RS-4), Dunlop Star Spec ZII, and Yoko AD08R are all very good options. These tires will still be up to the task of repetitive lapping, put down some fast lap times in the right hands, and will most importantly outlast the RE-71R by a long shot. Some enthusiasts are more than willing to trade a small difference in lap time for almost double the life. BTW, the Star Specs have the best wet grip of the tires mentioned should you frequent HPDE's where rain is possible.

Always a good idea, as compromises must be made one way or another when one wheel and tire setup is used for double duty. From a logistical standpoint, it is also nice to have a set of street wheels and tires ready to roll once a track day is complete. Worrying about how you will get home if your tire(s) are compromised on track is never a good feeling, and will ultimately effect your driving.

TysHenry, those are a 50 mm offset. Do you run a spacer on the front. You know my car, I'm on GT350 springs now and just ordered camber plates from Terry,

I'm going to order the SVE 350 wheels for next season, and want to fit 305 RE71's

Many of our customers (including GT350 owners) run the 19x11" ET52 square fitment with 305 tires, and although it does depend on your suspension, ride height and tire type, 20 - 25mm spacers are typically used up front along with extended studs to safely support them. Negative camber is encouraged up front as well to avoid rubbing the outer front fenders.

I ran 305 square setup for the STP class at SCCA solo nationals. RE71R tire is a great choice.
