Tires were rotated; now rides rough

prussell · 10-23-2009, 07:37 PM

I purchased about 3 weeks ago a 94 4.0, 6" lift, 33X12.50, Detroit lockers YJ. I just had the tires rotated and the jeep now rides really rough. Before, I could get up to 2400 RPMs in 5th gear and it ran really smooth. Now after the tire rotation, the jeep shakes and struggles to get there. Is this normal? Will it work its self out or do I need to have the tires rotated back. thanks.

probably uneven wear on the tires, most likelythe fronts, or they are out of balance.

I hestiated on getting them rotated without a tire balance. the whole underside of the dash rattles something fierce, even at low speeds.

Did they swap front to back, or did they swap front to back then cross the fronts? If they crossed them, put em back, we always have problems with crossing at work. Once you have a radial tire running one way, you shouldn't change that. Get them balance too. I had some bad death wobble on certain turns around town, balanced my tires and it's gone.

I am not sure on the order of the rotation, but I will get with them to have the tires balanced.

This is especially true of AT type tires because the rubber tread lugs actually develop a bit of an angle.

I try to rotate avery 3k when I get the oil changed. even at this small milage, the mud grips will wear with a slop on every lug, so when you rotate left to right, it reverses the tire rotation, and now the angle on the lugs is slapping the road, they will wear back down with milage.

So it looks like it would be best to leave the tires as is and after driving awhile they will even out? the rough ride should smooth out over time.

You can try to switch the front tires to see if they were crossed when you had them rotated, but what most are saying is over time the vibrations will get better and not to cross radials when rotating. I also rotate my tires every time I change the oil and have had no vibrations. The balance of the tire should be good as long as you had them done when you purchased the tires. Some may lose a weight, but chances are not.

If you just bought it then the previous owner probably had bad wear on the fronts and decided to rotate to the back. Then you came along and rotated them back to the front. Check to see what your alignment is at, there are some places that will check it for free(and try to push it if it's needed). I used to work at a tire place...
That's just a guess though, but it sounds logical to me
