I am planning to hit a few Time Trials this year with my Golf R. For NASA time trials, the car is classed in TTD with 14 base points. The stock tire size is a 245 wide tire. If I go with a 225 wide tire, I can get -4 off the points base, which takes me down to 10 points, and I have 9 left over before going up a class. That leaves me the option to use a Toyo RR, which I've used plenty of times before. Except, they don't make that tire in the size I need. Next up was the Hankook TD race tire. Closest tire is a 225/45/17, but then I'd have to buy 17" wheels for it, and I'm not 100% sure if a 17" wheel will fit on the R Golf.
I can go down a notch and head for the Nitto NT01, which they do make in a 225/40/18. I'm just not sure how good the tire is (no experience with it). The other choices in the +7 category are:
The following DOT-approved R-compound tires and those with a UTQG treadwear rating of
50 to 130: Maxxis RC-1 (ex. Kumho V700, Michelin Pilot Sport Cup, Nitto NT01, Pirelli
PZero Corsa, Toyo R888, Toyo RA-1, Yokahama A048, etc.) +7
The RA1 is an ok tire, but gets greasy when hot. The Golf R is a heavy'ish car for its size and a 225 wide tire may not be great for lower performance tires, which is why I'd like to go with the closest thing to a race tire so it will take the heat a bit better.
So far, the only tire I can seem to find in that 225/40/18 size is the Nitto. Are there any other good tires?
I would love to buy a Hoosier R6, but that is +10 points and would bump me a class, so unless I can find a way to remove any other points from my classification base, I'm stuck. Oddly Hoosier does make a R6 in the size I want.
