Speedo change with new 35 MTRs

I just got new rims and tires put on and I wondered how to get a corrected MPH speedometer reading? What can I expect the MPH diffrence to be from 32 to a 35 inch tire?

 

You're running the Dana 20 TC, so you are out of luck so far as a simple TC gear change goes. AFAIK there are no aftermarket gear corrections available.

The easiest is to install a cheap tach, get yourself an accurate tire diameter measurement (35's are rarely a true 35" in diameter) and hit a calculator like here

Or you could do the GPS thing.

I've also heard of adapting a programable wireless bicycle calculator to work. At least in theory, this should also work.

Short of switching TC's to something newer, those are about your only options.

 

What programable speedo due you recommend? do you run this in addition to the original speedo, and does it keep track of your mileage?

 

Now that you have 35" tires on can you take a measurement for me from the higest point. I am building a 73 and am planning to put 35" on mine but I need to put in a taller garage door and really need to know roughly how tall it is going to be

 

I measured 79.5 inches @ the highest point being the center of the roll cage... My garage (track home) is 83 inches and was supposed to be a 7 ft garage door and the jeep fits perfect.... I plan to add a 1 inch body lift to help with the clearance of my new fender flares... Just anyone recommend a specific 1 piece body lift?

 

thanks for the height info. A 7 foot door was what i was hoping for.
