Could you please measure the height of those tires? I've read that they run small are closer to 35.5"

They run small like almost all others.

37x12.50R17 Cooper SST Pro, with 1.75" spidertrax wheel spacers.

I was thinking that the KO2's will be best for me using the JLUR as a daily driver with some Colorado off roading but the Cooper SST Pro's on your jeep and the one in that extreme video that I saw yesterday look really good and have me considering those.

I have 33’s Cooper Stt pros on my 94 YJ and they are awesome. Going to buy another set for my JLUR. Very quiet tire and don’t hum like other mud tires. Previous had BFG and so glad I made the switch.

Pics as requested. My driveway is a slope if the side picture looks wierd. Camera doesn't pick that up well.

What has been your MPG since you put the 37s on?

I am interested in the answer to this as well, but I don't think you can trust what the computer is telling you unless you were able to re calibrate it somehow.

Good to know. I have no experience in this area. Thanks!

Mine is at about 15-16 mpg.

Haven't had recalibration yet but average around 13.5 vs 15.6 before

You must have a heavy foot, no? I get 17.8-18.0 on stock tires on my JLUR. But not a lot of hills around here either.

Not really. Hills but nothing large. Most of my drive is around 60mph.

We have 37" tires on our JLUR at ARTEC Industries the wheel is a 20x9 Raceline defender when hitting bumps too fast the tire would rub the inner liners and lower half of the flares which opened up more space . we can fully articulate the suspension to where it sits on bumpstops and the tire has about 1/2" of space all the way around the opening in the rear

Bad looking Jeep!!
