tire size question
tire size question This might be a stupid question but I need some help anyway.
When I took my car to the track this spring, I had on 305 35 zr18 Nitto DR's
The car is an m6 with a 12 bolt and 4.11's in it.
I had to shift into 5th before the finish line to keep it from bouncing off of the 6,500rpm limiter.
What size slick would I need to put on for it to give me the extra length needed to not have to shift that one final time?
Thanks in advance

Bringing it up to 7,000 would give you about 134 before tapping the limiter on the current tire.
As it stands, its bouncing on 124 mph
The limiter might be at 7,000rpm but I shift at 6k so I dont screw up and bend a rod.

Check on some high growth tires (slicks). You keep the same gearing down low, but on top from centrifical force you have a high growth tire you gain some gearing for the top end.
I'v done this before with GoodYears and have worked great! I just don't know if they make a size that will fit you application.

Would it hurt too much to just turn up the limiter to see where you cross the line at in 4th once or twice to see where you are at? What do you cross the line at in 5th? I'm guessing a 28" will work, you would be able to trap low 130's with that. What do you run now?
