You sure about that? When I went from stock 32"mt's to 35" Cooper STT's I noticed a pull to the left too. I also tried everything in the book, 3 different alignment shops, rotations, even running more psi in the left front tire, nothing worked. Disconnected my Bilstein SS and voila', no more pull. Pretty sure the only reason I noticed the pull after the tire change was simply because my rolling resistance changed considerably when I changed size.
Of course, ymmv.

Yup,

I had the STT's on my 2013 Ram (no steering stabilizer) and it pulled left. Tried everything to get rid of the pull and could not. Switched to a different tire and the pull was gone, in fact because of everything I did to correct the pull to left, the tire change caused a slight pull to the right. Undo the corrections and truck tracked staight as it should. Put the STT's back on and the pull was back. Discount Tire even tried a whole new set and the pull was still there. 37x12.50R17's and then went to 37x13.50R17's.

In your case, it sounds like everything you did to get rid of the pull helped. A gas charged stabilizer would put a small amount of pressure in the steering to the left and in your case with everything done to compensate for the radial pull, it was enough to correct it once that small amount of pressure was removed.

Thank goodness the new STT Pro's (which is what this thread is about) does not have the dreaded radial pull the old STT's did.

I doubt my steering stabilizer is causing it because it is the stock rubicon stabilizer which caused no issues prior to the tires. Thanks for the suggestion though because I know this can sometimes be the cause. I'm glad to hear that the STT Pro seems to not do this.

Regardless I will still try disconnecting the stabilizer one day just so I never have that doubt.

Do you even remember the ride home last night? From what's hanging off your front armor, it looks like you may have had a bit much to drink and waffled a water buffalo or something. On that note, do the treads clear themselves well of meat chunks like a good MT should?

Lol, I was thinking the same thing when I saw that pic. I had just come back from watching the new Vacation movie, where he drove through the cow with an atv ...

It was a bad coating that's pealing off. And I tested these tires on the rock today amazing at 10 psi

I went with the Mastercraft Coursers MXT over the sst pro's. Only because I did not want another set of E rated tires.
