There are tons of threads about this, but it all depends on your car. Like with my 215-35zr18 i hit 135 and with my stockies i hit 125ish. I highly recommend not doing that unless you want your car to look like mine did after having a bad day
Click Here What you can't see is that my wheels were turned in the complete different ways. Trust me it's not fun i have so many problems with clicking sounds and the steering isin't right anymore and they fact that i indangered the 3 kids and 1 adult in the car i hit on the highway. Be smart not a dumb ass, and the highway was empty just took one person to cut in front of me and 135mph.
