Swapping directional tires to opposite side

[BoxsterSteve]

Side-to side swap like this:

Left side tire goes to opposite side (obviously), but outer sidewall becomes inner sidewall on other side of the car. You are shifting over, NOT spinning them as you swap sides. This way you don't fool up "pumping" action of the tread design.

I used to do it on my old 5.0 'Stang back in the day. Pals thought I was nuts, but I got more even treadwear that way. Those cars had limited slip, but the tires wouldn't spin evenly on gonzo clutch drops.

Removing the tire and reinstalling it can cause the bead to fail. Every time you remove and reinstall, you have to stretch the bead to get the tire on the rim. Tires aren't designed for the bead to be stretched over and over- they're made to stretch just once during initial installation. Given that, I've done exactly what you are thinking of with my own directional all season tires and gotten a few more miles from them, and never had a failure (one "switch" only!).
I would NEVER do this with a track tire - way too much stress and risk!
