Gear speed calculator

Postby Sailor » Fri Nov 11, 2011 4:47 pm

I've been looking at what tyre I'll need to fit to my NC to get close to the same rpm/speed as std for cruising if I install a 4.1 diff for trackwork.
Found this easy to use program which although in MPH is good enough.

Looks like a 235/45/17 is close and would give a limo ride :)

Looks good - tks!

If you've not seen it, useful from a slightly different perspective, especially for multiple comparisons: http://www.1010tires.com/tiresizecalculator.asp
