Contour Enthusiasts Group Archives Forums Modifications Wheels & Tires question

hi i was wondering my sister took her car to the tire shop werer she bought her tires and they are saying that they cant rotate here tires because of the way the tires are wearing out. all i care is getting them balanced i could rotate it myself but since they are getting balanced minus well rotate them. the tires have like between 50 and 40 percent left. my question is why cant they rotate them? anyways i might be missing something here. anyways thanks.

This post needs more sentence structure and punctuation.

I had a tire place tell me once that they would only rotate front-to-back, but not side-to-side. Their rationalization? When a tire is spinning on direction it builds up tension, basically gets "wound tighter" in one direction. If you move it to the other side it is now spinning in the opposite direction (we're talking about blackwalls on one side, whites on the other, so the tire would have to be turned around) and basically begins to "unwind." They said this leads to tire failure and throwing the tread.

Personally, I think this was a load of bullsh!t. Anyone else have a better explanation than that? I'm curious to see what people have been told.

well i know it aint a tour it's a neon could it be the tire size i picked for the car? i went from a stock size 185 65 14 to a 215 60 14 on a stock steelie rims. the inside is wearing out more then the outside i know it needs an allignment but cant firgure out why they wont rotate it. anyways i have no problem doin it myself. i do everything i can do on a car but what i cant do i take it to a shop. well ya i do need to work on my punctuation sorry im not the greatest typer well thanks.
