|Tiki_Al||mighty helpful thread, i've got 32" tall tires and my speedo is out, and with all the average speed cameras we have to deal with here in the UK it's best i get it sorted ! Just hope my local dealer can get the speedo gear i need|

Also when replacing the speedo gear. MAKE SURE YOU DONT RIP THE ORING. I have a spare that i got from ace hardware for i think 40 cents vs 2-3 bucks from the rest of the stores specifically for jeeps.

|Warpman89||I don't want to hijack this thread, but what speedo gear would be best for 34" tires? I found some TSL's that are 33.8", but listed as 34", so what speedo gear would you recommend?|

Here's a chart of the right speedo gears for common tire sizes and axle ratios... it also gives instructions on how to change the speedometer gear which takes 5 minutes to do.

1.14 from derek but it sounds about right.. what tires did you have before? 30s or 29s?
mine from 30s to 35s was 17% off and i was darn close. I measured distance with my jeep and then with my gfs car and i got 17% difference. Now i have corrected speedo gear and i'm getting the exact same distance as her

|debruins||it will be 33/29 so multiple what the speed is on the speedometer by 1.14 and thats the real speed|

|jeepcop1||should be about 5-7 MPH. That's what mine was with 33x12.50's when I was going about 50 MPH.|

WOW, that was a fast reply. Thanks, I didn't think it was a big deal, but why not get some input.
YES THEY DO!

From a 30 to a 31, no you really don't need to.
BTW - Social Distortion rocks!

|CVFD76||i got a 05, 4.56 gears, 35's, and my sppeometer is only off by like 7 mph, so personally it doesnt bother me, no bigger change than u made i dont imagin it would be off by much|

Bigger tires, do I need to change the speedo?
So I have an 06 Wrangler 6cyl, 3.07 gear, no lift. I just changed from 30x9.50 to 31x10.50s. Do I need to change anything else, so the mphs and odometer stay the same? Hope this makes sense, thanks guys.
