Tire Growth
I used to run MT ET Street bias ply 26 11.50 17, in which the tire on their site actually says the tire is 26.5 tall. I'm going back with another drag setup but this time it will be 15's instead of 17's so I have different selection of tires.
I am contemplating running another 26 which will actually be 26 to 26.3 or a 27. Car is a non Z51 LS2 with 4.10's in the rear. Redline is set at 7100. I've done the gear ratio calculator and the if I get the tire that measures 26.3 before tire growth it will give me 135mph in the 1/4. That should be enough since I plan to do 133-134. I called MT and they say their bias ply at that mph will probably grow 1-1.25". Say it grows to 27.3 that will put me at 141mph which is plenty. I want to have a buffer on the mph so I'm hitting the rev limiter when going through the traps since I don't want to raise it. Would you go with a 26 and hope it grows enough for the extra mph or would you go with the 27 to be safe?
Thanks,
Andrew
