CAUTION: Hymotion and all PHEV owners! Tire Treadwear!

drees · 10-14-2009, 01:58 PM

As Fred says, if you're seeing excessive wear on the outside edge of the rear tires, you very likely have too much toe-in. You should see slightly more wear on the inside of the rears due to the slight amount of negative camber.

On the fronts, the outside shoulders will tend to wear a bit faster due to cornering forces.

Moral of the story - get the alignment checked, front and rear!

O.K. - here is a picture of my rear driver's tire. The tire was put on after the Hymotion install (could not stand the OE tires - these are Michelin Radial Xs) and has about 12,000 miles on it. As you can see, tread wear is very even.

I don't see anywhere you mentioning if the balding tires are stockers. Many here simply found that the Goodyear Integrity wore poorly ... rotated or not ... and of course if you DO take too much time to rotate, than that just amplifies the condition. Are they Integrities?
