Regearing, need speedo gear?

slickemhoundd · September 19, 2012

Im running 3:73's and putting in 4:56's. Im now running a 33" tire and might be slapping in 35's in a couple weeks. Want to know if i should swap the speedo gear or if i should be okay. As of now its off from 35 mph and up going from 1 mph off up to 10 mph off at 80 when reading 70

I'm pretty sure 35"s and 4.56 will give you pretty close to stock readings...but I'm not quite sure on that. I've read multiple times that 4.10 and 32"s/33"s give you close to stock readings, so yeah.

EDIT: oooo charts are fun! http://www.jeep4x4center.com/jeep-tires/tire-gear-ratio-chart.htm

I like that link, kept me occupied tire shopping! My only question with that chart is it being based off of a jeep trans BUT i believe they arent to far off

It's calculated from a 1:1 ratio, so if you have overdrive these will be higher than what yours reads, but it's still a good guide. I see it as if the rpms are fine on this chart, they'll definitely be fine on my truck with the overdrive.
