I'll be recieving these in 35x11.50R20 tomorrow and need to adjust my speedo. Nittos website does not state the rev per mile to adjust. Am I missing something or does anyone know the number I am looking for?

I am not positive what software you're using to update your speedometer, but with mine it asked for the height of the tire, not the revs.

I would say 600 revs.

I'm using the SCT X4 tuner, I'm pretty sure it's done in revs per mile.

Is that a guess or is that the actual number? I'd like to get it right on if possible.

This says 594.

Thanks I didn't know I could do that, I wonder if I can punch in 34.76" diameter lol. I'll have to play around with it.

When you set it, check with an accurate GPS . Different manufacturers are mostly all different in the dimensions..dunno why but they are

Good thinking thanks

I would start at 600 then go up or down 5 revs/per/mile depending on if the speedo is reading to fast or to slow.
