I usually do if I have the permission to. A close friend of mine that still manages a Goodyear that I once worked at usually lets me do my own. It's not as much as mounting the tire I'm worried about (unless there a tpms sensor), it's the balancing of the wheel that I'd much rather do myself.

If I currently have 255/40/17 on the rear with original Porsche rims, can I increase the width anymore? Wider is always better looking as far as I am concerned, but I don't want to change wider aftermarket rims. Any suggestions? I'm running 225/45/17 on front btw.

Thanks guys for anticipated input
