Tire size with 3.73s

[DaBigBone]

Curious to see what combo people are running. About to order new wheels and tires for the track

Car is a '14 M6 with 3.73s. Obviously I don't want to shift into 5th in the quarter. Was planning on a 28x11.5x15. Anybody with a similar combo able to chime in?? What speeds and rpm are you crossing the traps?

Currently trapping about 112-114 but will be adding more mods soon

3.73s and a 28" tire will take you to about 125 mph in 4th gear at just under 7500 rpm.

Unless you're adding boost, that tire would work great.

Thanks for the help!

So 305/45/18 is the way to go I assume? For someone in a 18x10
