Hey total newbie question here.....I have a 4.5" AEV lift 5.13 gears (with an auto). I need new tires in the next couple months. I'm running 35x12.5 17 ProComp extremes now and considering 37s. I comute to work 8 miles every 3rd day but do travel on the highway on the weekends. Am I going to hate 37s?

I have 4.10 gears and 37's. I hate my gears but love my tires.

Actually, it's not that bad. I would love to regear but it's not on the top of my list.

I think it will be fine with 5.13's. You could always run a smaller 37" like a km2 if your concerned

Plug some numbers into the rpm chart in the drivetrain faq's to get an idea.


Assuming a 36" actual height:
Auto, 5.13, 36" = 2313 rpm @ 70
--- auto jk's have a .69 OD
2313 / .69 = 3352 rpm @ 70 w/OD Off (or a downshift to 3rd)

Lighter tires would be better than heavier, and 5.38's would be a better choice for OD rpm's, but it won't be horrible.

Hey man!! I use the Bfgoodrich at in 37" flavor and love them. Awesome road manners and only about 66lbs. Do run little smaller than say a mtr or Toyo but to the naked eye not much difference. Hope this helps. Stay safe bro!

AEV 4.5" with 37s, 4.10s and love it. I do need to regear, but don't regret 37s at all. It's my DD too

I love my 37s for daily driving.

Haha I have 38s and stock gearing, it's not that bad.

I don't have that setup but they always say if your thinking about it, you'll regret not doing it.

I actually stayed with the 35s.....was planning to do the gears and backed out. *sad* But I'm running pitbull rockers now and they are awesome!!!!
