I have basically switched vehicles with my dad (he got a very nice '93 ford escort wagon; I got an old, beat up dodge caravan).
Anyway, the fellow that gave dad the van says that the tires must be rotated with some special care due to oversized rims having been placed on the vehicle or else the tires will roar.
The tires do roar, but is this a real concern? I've never heard of it before. If I am understanding him right, the rims must be left in place and only the tires rotated (I may have MISunderstood, of course). Seems really odd to me, and I can't imagine having to explain this every time I want my tires rotated ("Oh, you have to remove the tires from the rims, btw").
Anyway, I wanted to see if anyone can confirm such an idea before I go making an idiot of myself at the tire shop.
Thanks.

I'm no automotive genius but the tire noise I know of comes from knobby tread. I can't imagine why you'd change the tire on the rim if everything is the same size, maybe he talking about changing the direction of rotation. Sounds wierd, I'd go back to a stock arrangement, the manufacturers have more experience.

Depends on what type of tires. I have 18"(oversized) eagle alloy rims on my lowered s-10. The tires are low profile Kumho ecstas directional. If you were to rotate them you could only swap from the front to back, without breaking them from the rims and re-mounting them.

If I'm not mistaken, my dad recently purchased the cheapest (or second-cheapest) tires he could for them (probably at WalMart). They are just passenger tires, nothing special about the tires except that they were oversized to fit the non-standard rims.
If I'm readin' you guys right...the rims hardly matter at all as far as rotation goes, but certain kinds of tires must not be rotated to the opposite (passenger vs. driver) side.
Do I have it?

I HIGHLY suggest that you take the vehicle to the closest REPUTABLE tire store and let them tell you what to do. Explain what it is your father/previous owner told you about these particular tires and the rotation method. it is very possible that they are directional tires and that is what your problem could be, However NOBODY here can see what you have on the vehicle and without being able to physically see what it is you have on your vehicle I for one will not give you any technical advice that I could feel comfortable with and why would you trust the knowledge of a sign person about tires over the knowledge of a tire store. Would you trust a tire store manager to design your next sign?
I have over 24 years experience as a mechanic, Have ASE Master certifications and even I couldnt give you a definite answer without more information.
From what your telling us, you dont understand what is on your vehicle well enough to be able to convey the proper information. Tires and Brakes are the most critical safety items on your vehicle, Dont take chances!! Seek professional advice.

William: They may be referring to the fact that sometimes people put different sized rims on vehicles and they will work fine on the back but not on the front because of the disk brakes on the front.
I got two extra rims for my mother-in-law’s car so we could mount winter tires on them...they worked fine on the back...later four new all season tires went on the rims but the “extra” rims wouldn’t clear the calipers on the front...so her tires couldn’t be rotated...unless they were taken off the rims...which isn’t practical for tire rotation.
With regard to the roar...”cheap” tires can have a tendency to be louder...I believe it has to do with the rubber compound.
That’s my 6 divided by 3 cents worth.

William, there is a partial truth in not changing the direction of rotation. As far as I know, this only applies to what are called "uni-directional" tires. These have an arrow on the side of the casing. It has nothing to do with the tire casing, and everything to do with the tread pattern, as in say rain tires. The treads are shaped such that they throw water out---turn them around and the tread will try to pull water towards the middle of the tread.
Some of the early radial tires it was said should not have the rotation direction reversed---supposedly that could lead to ply separation. I don't think that is the problem that it once was.
The other thing that comes to mind---having recently run into it-- is interference between the rims and the front brake calipers. If the wheels will turn at all, they will be noisy.
I recently changed trucks---same brand and model. My snow tires on older cast wheels would not fit. Bolt pattern and center hole measurements were right, but the calipers on the front had been made thicker/wider, and the backs of the rims collided with them. Couldn't tighten the lugs, and the wheels wouldn't turn at all. Changed over to steel OEM rims ---problem solved.
FWIW.

Oh, Geez---I just read Harris' comments. William, forget everything I said.
