Tread depth variation - problem with quattro?
A friend told me (Subaru) that the variation in tread depth on the tires cannot exceed 2/32, otherwise the differentials will wear out!
Is there any truth to it, or a tire salesman myth? |
If you run it with more than a .5/32 variance between tires, your car will promptly explode upon ignition.

According quote below, the correct number is "4/32 of each other in remaining tread depth". There are several suggestions that have been offered to drivers who are replacing pairs or individual tires on their four-wheel drive and all-wheel drive vehicles. Some vehicle manufacturers recommend that all tires maintain the same rolling radius and circumference, while others suggest that all tire circumferences remain within 1/4- to 1/2-inch (8/32-16/32) of each other. Other vehicle manufacturers recommend that all four tires remain within 2/32-, 3/32- or 4/32-inch of each other, or within 30% of each other in relative Audi: As published in their vehicle owner's manual, "rolling radius of all 4 tires must remain the same" or within 4/32-inch of each other in remaining tread depth. Porsche: Cayenne within 30% of the other tire on the same axle's remaining treadwear. Subaru: Within 1/4-inch of tire circumference or about 2/32-inch (1.6mm) of each other in remaining tread depth. |
