but how many accidents occur at any less than 9/10th's? /and/ adhesion

right, but if it's bent, straighten it! that's why we check these things!

unless the car's lowered and as long as the bushings are factory,
standard settings are fine.

 

yet OTOH, I've only seen a few punctures on the Prius/Potenza Combo...
Perhaps you just had a string of bad luck?
But seriously, When the Prius came out it was pointed out that the tires had
a heaver load rating than Standard Potenza's--We had to order extras in. We
saw a lot of premature wear on those tires, not lasting near as long as
needed, so the BOSS suggested bumping the pressure up a bit (34psi I
believe) and the wear slowed down. A local shop put a Toyo on the car and
when the dealer saw it they suggested the car be towed to a good tire shop
to have a proper tire with the adequate load rating put on.


Now this is all fine and dandy; and mind you this is Toyota thought process
not my personal thought. Just be sure the Pirellis are rated for that car.
