Rear alignment?

[Cougar_Marauder]

I am about to put new tires on all around and have the front aligned to carfixers specs but was wondering if there is anything that can be done to prevent the uneven, inner wear of the rear tires. I thought I read something about adjusting the rear toe or something at one time... (can that even be done? I don't know much about that stuff). I haven't found anything in my searches, maybe it was all a wonderful dream. Are our cars doomed with this forever?

Other than increasing the rear tire pressure to the 38-40 PSI range, I have not seen anything else here in 6 years that addresses the center tire wear on the OEMs.

^^^^^ What Charlie said ^^^^^

The OEM rears are prone to accelerated center wear. Running higher pressures helps somewhat, but the only "real" fix I've found is going to an aftermarket tire. I'm running General Grabber UHPs and they're wearing great.

I'm running large Continentals on the back at 42psi and experiencing excellent, even wear.

Rears don't wear on the inner edge like the fronts, they wear in the center. Increase the pressure and it helps.

Rear alignment can really only be done on cars with IRS (independent rear suspension) instead of a live axle. When they align our fronts they also connect to the rear wheels for a reference point to adjust the front suspension so the car doesn't track sideways down the road.

Yep, 4 sensors laser aligned on all 4 wheels... Ah good old alignments :puke:

We had the ancient ghetto alignment machine where it was a drive on rack, then you had to chock the rear tires, lift the whole rack, lift the front, then lift the rear, lower the whole rack, mount the sensors, calibrate everything, lift the whole rack AGAIN, then lower the rear, lower the front, drop the whole rack.....

and THEN... THEN you could get a reading. :lol:

Thanks for the input all. I am going with KDWS all around, I will increase the pressure up some and let y'all know if I have any problems with em.

Don't forget, the rears are different size from the fronts.

Thats how we do it at work.

If you've got inner tire wear on the rears you may have bent something.

Did you have to run the "strings" too?

Yep everything had cords lol :shake:

It's a PITA, especially in winter.
