Got a lovely litle flat on the Subaru a few nights ago – fatal stab wound to the sidewall (well, glass most likely – I doubt we got slashed!), not repairable. So the dealer dryly informs us that because it’s an all-wheel drive, it’s critical that all tires have exactly the same radius. If you mix worn tires with new on an AWD, the constant work of matching rotational speeds in the differential can heat up the drive train and cause damage. Hrmmm… Amy does some quick googling and comes up with this — apparently it’s possible to buy just one new tire and have it shaved — lathed down to match the tread depth of the other three, for a sum total of $35 over the cost of the new tire. Wonder why the dealer didn’t suggest shaving… (a facetious question, in case it wasn’t obvious).
