2006 STS Tire Size

Rear tire is larger than the front. Can you run the rear size on the front also, that way you can rotate them. Can this be done without hurting the drive trane?

Some Cadillac STS’s have the same tire size, front to rear - and some do not.

  • AND -

The ones that have different tire sizes also have different rim widths!

  • AND -

The difference in rim widths means you can not mount the front tire size on the rear rims.

  • AND -

I’ll bet the rear tire size will rub on the front.

thanks for the reply…
