Since the restriction is that the tire should be rolled in only one direction, would it be okay to unmount a tire, mount it on the wheel reversed, then rotate diagonally? Has anyone done that? That switches between inside and outside sidewalls, so is not aesthetically desirable for colored sidewalls, but I see no other problem. Presumably, one should rebalance the wheels. -- George Tomasevich, ihnp4!twitch!grt AT&T Bell Laboratories, Holmdel, NJ

I seem to recall GM anouncing about a year ago that they now recommend the standard X rotation for radials. (84 or > GM owners, check your owners manual) -------------------------------------------- Brian Millham AT & T Information Systems Denver, Co. ...!inhp4!drutx!review

i still have a 1974 dodge ramcharger 4x4 and got well over 50k miles on the tires by rotating them LF <-> LR and RF <-> RR every 5k miles. At about 30 k, i noticed some asymetrical wear on the outside edge, so i swapped LF <-> RF by dismounting the tires from the wheels, remounting them with the whitewalls on the INSIDE and putting the tires on the opposite sides of the car so the tires would rotate in the same direction. I did LR <-> RR the same way, and had no problems. cdash

I'll probably be raked over the coals for this opinion, but... I don't believe in rotating tires. My first set of radial tires lasted 65K. I replaced them because winter was coming on. They would probably have lasted another 5-10K. The second set for that car (Honda Civic) went 45K. I sold the car with those tires in good shape. Again, no rotation. Now I own a Honda Prelude. When the dealer rotated my current set, the car developed vibrations it never had before. I immediately went back, said: "Unrotate!". They did and the car was fine again. I have 20K on the current set with no noticeable wear. "But the tires will wear more evenly if you rotate." Bunk. Why wear out all your tires instead of just one. If the car is out of line, get it in line, and replace the one bad tire. You want to rotate? Fine. But I think you'll have to give me a good reason to do it. ...bob garmise...at&t bell labs, columbus...

You wouldn't get raked over any coals in the UK for two reasons. 1) Arthur Scargill wouldn't let you have any coal and 2) It is simply accepted that you do not rotate radial tyres. I had a Ford Escort (when they made them properly with rear wheel drive) which I sold after 3 years 42,000 miles with very good tyres still on it. My next car (which I still have) was a Datsun 120Y coupe (probably known here as a 210 coupe?) which is on its second set of radials at 89,000; they will easily see 100,000 and have not been rotated. It is, of course, accepted that with cross-ply tyres you should rotate. (Don't ask me why, I only report what is accepted) Drive safely! -- anything herein expressed is my views not those of my employer ihlpg!jcgowl Roger R.

Case 1: Say you have ~30K miles on a set of radials and you notice abnormal wear on only one rear tire. If you replace only that tire, you could have a difference in tire diameter from left to right by maybe 1/8 in. This does not seem like much, but it causes the spider gears in the differiential to always be turning (as if you were constantly going around a slight corner). Also the torque excerted by the tire and wheel on the brake unit would differ from the left to right side of the car. This could really cause uneven braking when the difference is between the front tires. Case 2: If you every buy a 4-wheel drive vehicle, you must rotate the tires. Any difference in tire diameter from front to back will cause the transfer case to bind, except on the most slippery surfaces. Also your opinion goes against all tire manufactures recommendations. Also tires and wheels should be checked for balance at least every other tire rotation.
