Welll took the car in for B1 service. Oil change, tire rotation, and inspection. Well i marked my tires, and i checked when i came back home, and they didnt rotate my tires right. They didnt cross the front 1, to the back, and didnt cross the back ones to the front. They just put the front right tire on the rear right tire. And the left front to the back left tire. What could happen.

 

normal for a dealership to do this

 

sounds ok to me -- do you have unidirectional tires?

 

Normal at the dealer, even if the tires are not directional.

Word to the wise - don't cross rotate them later; keep doing it the same way you start.

 

is that to maintain the camber?

 

This is the right way. You can this way or cross way

 

It even says so in the manual.

However, the X rotation cannot be used for directional tires.

 

Idk, every good mechanical place says ur supposed to cross the tires. And thier stock mx tires, so i dont think thier undirenctional.

 

Incorrect way to rotate non directional tires.If one were to look at their owner's manual, it shows the rotation for both directional as well as non directional tires.

As far as starting a cross rotation, it certainly won't cause any problems, unless the camber/toe is out of specs, and that would be a problem on the first cross rotation anyway.

 

Why?

 

Guys,

The manual tells you how to do it criss-cross for a reason. Tires that roll one direction get "cupped" and they have high spots. Eventually they get noisy and rough if left this way. Rotating them files down the cupped area because eventually you will be turning all of them the opposite direction.

On uni-directional tires you have no choice but my stock Michelins can be. My tires look great with even wear and run smoothly.

If your alignment is altered by winter etc., the tires that get roatated will get worn unevenly too, so bear this in mind.

I'm no expert, but this philosophy has served me well on all my rides.

If your tires have a >>>ROTATION marking indicating which way they are designed to rotate, then you can't move them to a different side

 

Well, maybe I should've said, "Not surprised, they did the same thing at my dealer." I called 'em on it. They said that's the only way they do it - directional or non-directional tires. I was running stock MXM4 at the time, 9500 miles on the odo.

I continued that way (NOT cross rotating) for a couple of tire rotations. I noticed a little excess wear on the inner(?) edges, probably camber from the drop.

So, I figured I'd cross-rotate and hopefully even out the wear. BIG mistake. Tons of vibration and created/amplified rattles galore.

So, my suggestion is: do it one way or the other, but don't start out NOT cross-rotating, then later change your mind.

 

Just what I said about vibration with irregular tire wear, but you should have encounter a slight vibration even when moving from to back as the wear patterns on each corner is probably different in this case. Got to pay if you're going to play by dropping the car and not having it aligned into the proper specifications.

If alignment, front and rear, are within specifications as indicated by trear wear pattern, no abnormality should be expected, other than possibly a rebalance regardless of the time of cross rotation.

 

On non-directional tires, I would usually cross the fronts to the rear and move the rears straight forward.

 

Just do your OWN tire rotation........

 

Agree. The camber was out slightly; known to be out and chose not to have a camber kit. Tire life/tread depth seemed to be fine, tires would've made 30k easy. The little bit of wear was not really significant.

But "wearing them in" that way, then cross-rotating created an issue.

And that's my point: Do your rotation one way or the other, but don't change later on the same set.

 

There shouldn't be a problem any time one wants to a cross rotation as long as the tires don't exhibit any abnormal tread wear, that's my point.

Anytime a tire wears with an irregular pattern, it will cause a problem whenever it is rotated front to back or side to side because of the change in contact patch.
I'm finished.

 

how can u find out if ur tires r directional tires. i have kumho Ecsta ASX

 

Look for something like this on your tire:


>>>> Rotation

OR

Rotation --->

etc
