tire rotation

[sledhead]

I have all new shocks for the drives,tags on the way ,replaced the front shocks late last year. Now my 4 drive tires have a small amount of saw tooth on them and was thinking of rotating them from left side to right side (change direction ). Tires are only 4 years old and have lots of tread left. Will this help or hurt ?                          thanks     dave

what brand of tire and tread profile?

Dave,

If sawtooth means the treads are feathered to one side on all the tires on the drive, I would think the rearend is out of alignment.

Changing them to the other side will not correct the problem. It might make those tires last longer or wear
the tread to the other side of the tire. But the initial problem would remain.
I know less about MCI's than any other bus. Most have radius rods to adjust.

The tires are firestone fs 400 315 80r 22.5 , you can't see the feathered edge but you can feel it if you run your hand from back to front. It feels like the tire is bouncing when driving at about 73 mph. All tires have bean balanced and I have balance rings on the front tires.I am hopeing the shocks will stop this .The old shocks don't leak but it's time to be replaced . thanks    dave

If the tires are all the same-rotate them whichever way you want. The old belief that radials can only rotate one direction is not true anymore. Good Luck, TomC

Was thinkin of the left side (inner,outer ) move to the right side and vise versa on the right side to the left. All tires are same age,size                  thanks   dave
