Hey guys, I realized on my Tune I have I calibrated my speedo for the 4.10 gears but I never accounted for the 18" rims and new 295/35/R18 Tires I have on the rear! Anyone know the revs per miles so I can get my speedo correct!? Most sites online say revs per miles are 772.2 so I made it 770 which was the closest I could get. But my bama email tuner said as close to 798 as possible? Am I missing something what is the right answer here!

Only 1 way to find out for sure. Measure out a mile and start rolling

Oh god lol! Does know one know for sure!? What do you mean faster the higher number? Because Calculation sites say 772, and the tuner said the 798. So im so confused!

Smaller circumference tire will have higher number of revs per mile than a larger circumference tire. Looks like the tuner is based on a smaller tire circumference than what you're running, hence the higher number ? Just guessing.

Tires vary in size somewhat, even the same size from two different manufacturers. The best bet is to go to the website of the company that made your tire, and check the specs. Revs per mile is usually listed.

Thanks guys! I found it, all is solved!

That's great, don't leave us hanging, what was the problem?

Not really a big issue just the speedo always seemed off and I couldn't get the revs per miles right but with a little digging on the BFG site it was there in small print lol
