I had the same problem with the old style STT's in a 37 on my Ram. No such issue at all with the new STT Pro's.

ID:	628105 37x13.5x20 stt pro on 20x10 xd heist. They ride well on road with no pull aired at 31psi. When i first got them mounted they over aired them to 40psi and then only did my jeep wander. So check tire pressure if alignment is good.

I've got Cooper STTs on my JK in the 37" size. I have almost 50K on them and they will be getting replaced soon. I do a 5 tire rotation including my spare. Absolutely no complaints. They look great and functioned just as well. I plan on getting the STT pro as I can't imagine that the quality went backwards.

Great tire!!

I will most likely replace my STT's with these when it's time. I truly like Coopers and they did a great job on this design. Mastetcraft Coursers look good too. Thanks for the suggestions. I only run about 28 psi myself.

I saw a set of these in 37 R20's at the tire dealer a couple weeks ago. I suspect these tires will get a very similar life span/ride quality/ off road performance as the Mastercraft MXT's. I really like them. Rather or not I go with these or MXT's when mine wear out will be solely based on price.

Did you try disconnecting you steering stabilizer? Most are gas charged shocks and will push you tie-rod to the left. I want with the Fox ATS and my left pull went away.

Its radial pull caused by the tire/tread pattern.
