Meaty tires. Anything less is salami slicing. 4, 345's. The 2 on the left are worn PPS's. The 2 on the right are Mich Cup. :tup: The Cup tires have a stiffer sidewall.

Rears are easy. Get crazy up front and then let's talk. :rofl2:

335's in the front

My dream is 325's on the front. :tup:

Does it have a big difference in Autox? In race tracks it is not worth it as it make the car slower in long straights, but Autox is a different story, but I am still beginner for wide tires, the most I fitted was 285 on front :rofl2:

Yes it does. For autox you typically want the widest possible tire you fit on the car and stay within the class rules. Some classes have max wheel and tire widths and others have weight penalties for wheels over a certain width. In my class there aren't any restrictions beyond how much fender you can cut for clearance.

The one downside I've seen moving from 315's to 335's is generating tire temperature. That extra inch of width per tire makes a huge difference.

V1 Nismo rear wheels extended To 12.5 in width, anybody here?

Wonder what the specs are? And how much room between the sidewall and shock? If I read that right. They're using modded Nimso rims.

Looking at the picture, I don't see any spring buckets either. Must be on true type coilovers. If I can get the spec I feel the need for 2 new rims on the rear to fit bigger tires.
I am not modifying my Nismo wheels.

On 2nd thought, I will just go with a slick.

That's Ben's car. It just made a little over 900whp with a Vortech V7 supercharger

The only problem with getting crazy with the tire size is they weigh a ton. It will decrease your performance significantly if you are NA. A boosted car will loose some hp but it is gained back with better traction. I noticed a performance difference when I put the R888r's on my car before it went in for the TT upgrade. The RE11's were not bad at all.
