If anyone is running this setup what are your RPM's at 70-75mph with a 22re. Just to nip it in the bud, I don't care about 35's with 4.88's or 38's with 5.29's. Title specific only please. And for legal/environmental reasons it's running on the salt flats of Florida and it's treading lightly.

 

Dont have em, but my fancy "geek math" excell program says about 3023 at 70 and 3239 at 75, this is using a 35" rolling diameter, which is about 1.3" shorter than the actuall 36" swamper... so about right.

 

Here's the fancy one: http://www.grimmjeeper.com/gears.html

 

yeah my excell program pretty much does all that with fewer inputs since its for toyota stuff. I also have one with 05+ taco and 03+ 4runner tranny ratios...

oh yeah and mine lets you use odd sizes like 33.7", which is really what my 35's are when you look at rolling diameter.

 

im in fla and im about to have that same setup (5.29's and 36x13.5 iroks) on my 84 with a 22r. ill let you know how it does but im thinking by the calculations it will be damn near the stock tire/ gear ratio

 

thats probaly a good combo i have 5.29's with 35's and i feel my 5th gear is a bit to overgeared...but keep in mind most 36's measure almost to be a 35" tire. i know my spare 36x14/50 TSL is the same diameter as my 35x12.50 trxus m/t
