I call BULLSHIT! I'm running those 315/70R17 Goodyear Duratracs (largest 17" size they make) they are 33.8" brand new..... I love the tires performance but I definitely DON'T like how small they are. Mine are about half way worn maybe slightly more and there measuring 32.9" now :thumbdown:

I'm dreaming about a Duratrac 37x12.50R17 in C load range.

I just jumped from 285's to 37x12.5x17

It takes a lot of prep to support 37's vs 35's

That said, 37's are awesome!

I haven't actually driven my JK because I'm waiting for some custom drive shafts...

But just sitting in my driveway they are extremely impressive

They'd probably measure 35.5" tall. :-D

I missed my 285's when I went to 37's but there is always the MTR/K's

I sold the Duratrac's in less than 24 hours

I went with 285/70/17s and I am happy I did NOT go with 315/75/17s. The wider tire is worse on gas mileage and deeper snow.

I have 285/70/17 (11.2"x32.8" ) duratracs on wheels with 5.2" backspacing and they fit perfect. I know everyone always says you need 4.5" backspace, but AEV wheels are also 5.2". When these wear out I will probably go up to 285/75/17 (11.2"x33.8" ) Toyo AT2 extreme. The extreme versions are more aggressive looking AT tire like the duratracs, but have a 3 ply sidewall.

True AEV wheels backspacing is 4.7'' tape mesured not 5.2'' like AEV says.

How do you think a Goodyear MTR/K 37"x12.5"x17 will do in the snow?

Air down or put higher pressure?
