RPM Tire size

[shawn13]

I'm looking for a chart too find out what size tire to run ?
I want to go threw the traps around 6300rpm.
I have 4.10 gears 5 speed manual .
Thanks

You can't do it that way because your rpm is based on speed, not distance.

You have to know what your approximate trap speed is in order to go with the right gear/tire.

Well hell I think I'll try the 28"tall tire first.

How much rwhp do you have and how much does your car weigh?

Actually, why don't we do this: we will work backwards.

This calculator shows that a 28 tall tire, a 4.10 gear is 127.9 mph at 6300 rpm. Now whether your car has the rwhp to reach 127.9 mph at the end of the 1/4 mile is a totally different story......

I ran a 28" MT drag trap at 5800 and 26" MT ET at 6300 126.7 mph with 410s manual.
