Cant help you, but curious to the MPGs you are getting with those 37"s for research purposedI am currently running 37/12.50/20 on my Gladiator. I am wondering if there is a 37 inch tire that fits in the 245/75/17 spare rim? Or do I have to purchase a new rim as well?
With my setup, my JTR (3.6, 8-speed auto, 4.10 gears) on 37's and 20x10's, with the Tazer JL Mini recalibrating my ECM to the 37" tires, and the iDrive unit set to U-7 mode, I'm averaging 14.6 MPG's around town...Can't tell you highway, as I haven't been on the highway since the night i brought it home (I don't travel much anymore). Brand new in stock form on factory 33" Falken WP M/T's, I was only averaging around 12.5 MPG around town.Cant help you, but curious to the MPGs you are getting with those 37"s for research purposed

Some folks say the Tazer and iDrive are a waste of money, but I'm getting over 2 MPG better around town, with WAY heavier tires & wheels... Not to mention the excellent acceleration performance increase from the iDrive unit... So to me, that's well worth the money.
