I just lifted my Jeep and put on a set of 35in trail grappler's. The Jeep had a serious pull to the left. I had my alignment checked and it was good so I just had a friend come over with his Jeep and we switch tires and wheels. My Jeep drove straight as an arrow. Prior to this I had switched my tires left to right and front to back but it always pulled to the left.

Logic suggest that if you are pulling to the left and your tires have radial pull, you should be able to switch them left to right and it should pull the other direction but it doesn't. It still pulls to the left under every scenario expect when I ran a different set of tires which fixed the problem.

What is the deal? Have any of you heard of this before? I have searched the Internet and people report problems with trail grappler's pulling to the left but, again, if you move the tires around it should affect the direction of pull, right?

 

borrow a friends tires and see if you're still pulling to the left. If it is the tread pattern that is causing the pull rotating them won't do anything.

Some suggestions from previous threads on this were to: run higher/lower psi on one side. Some gas charged stabilizers are known to push in one direction, so that may be an option to counteract it. Or the alignment is set up to push a bit to one side to counter the crown in the road, so that might be an option to look into as well.

 

I respond to one of these threads once a week, I really don't bother reading beyond "trail grapplers pulling left"

 

Is it just the luck of the draw with Nitto? Will some run true and others pull left? I hate to compromise the setup to make a bad tire perform ok.

I also realize you respond to a lot of threads and I appreciate your help. I read all the threads I could find on most Jeep forums and I have heard about tire pressure, steering stabilizers and alignment corrections. I have tried all of that. Today after I switched tires with my buddy I realized that my suspension was good and it must be the tires. I thought it was radial pull but that's not possible. I guess it could be tread pattern but that would mean that the problem is much more wide spread.

I would like to know if you think it is the tread design that causes this problem.

 

Did your buddies jeep pull to the left with your grapplers on it?

 

Seems like it, I've searched about it and it seems pretty common. I'm running 35s TGs right now and need to tires soon and was going to step up to TGs in 37s, but the pull is getting annoying so I'm looking at other options.

 

We didn't try. I just put is on mine. His Jeep was stock so I wasn't sure if 35's would have fit or not. That would have been a good idea.

 

I'm no engineer or tire expert, but to me it definitely has to be the tread pattern. The fact that the lugs point one way and pull left, and every set of toyo mt's I've had pulls right and the lugs point the opposite way of the trail grapplers makes enough sense for me.
