This is the second straight set of Pilot Sport A/S Pluses that lasted only about 20,000 miles, even the tires are 500 tire wear rated and warranted for 45,000 miles. I got a 35% discount on the most recent set due to their short life.
Some other details are that I have the tires rotated every 5,000 miles and keep the alignment in check (by the dealer), I keep the pressure at 40 psi in the front and 44 in the rear (keep in mind that this is a 600hl and is supposed to be about 4 psi higher in the rear).
The tires are wearing on the edges, not the center. Seems like low pressure, but 40+ seems fine. (the spec is 36 front and 38 rear cold).
Oh, they are stand size tires, 245/45/ 19" stock rims.
Since it is, alas, time for tires again, any ideas?
