Got my Speedo corrected and about 200 miles of driving since Saturday night when I figured out what was wrong with my Jscan. Speedo is dead on using 3 apps and Google maps. I'm sitting at 16.6mpgs and that's about 80% city and 20%Hwy driving. After today my interstate driving should increase back to the normal 50/50 city/HWy. I'm feeling pretty good about that. I think I can get it over 17 which was my goal, it's steady climbing

What size did you set your MTRs to? I set my MXTs to 36.7, which is the spec on their website, but my speedo is still off over 5mph. I need to reset my Tazer.
From reading, I know the MTRs are a big 37" tire, like my MXTs. They barely fit the spare tire holder but not inbetween the frame rails.
Thanks for any info.

36.2 got mine dead on. They measured slightly taller but I just set it at what the measured at mounted on the guys wheels. It ended up being right first try. Mine are worn a little about 70% tread left. I'd try 36.2 and work your way up if you need to.

Just got it to 17mpgs on my way home from work. That's where I wanted to be at, I'm super happy. On Cooper AT3 XLTs I should be able to do even better.

Here they are, super happy with them. On a side note my dang Jscan bluetooth adapter isn't working, it want pickup the Bluetooth on my phone. I guess my computer will be off for a few days, we will see how that goes. Love the 37's , hour ride back to test them out

Added almost 2" of height over all in the center of the jeep. I'll probably air them up a bit, they have them at 30psi right now. I'm at 22" in the center of the truck now
Did you have a lift when you added these? If not, I'd be curious to see how they look without it. Thanks!

Yes, I already had a 2.5" ReadyLift kit and Rubicon front springs. I ran my 35" BFG KO2s without a lift kit for a few days. Based on the amount of space with the 35's I would of probably been pushing it on 37's, these are at least 2 inches taller mounted than the BFGs were.
