So I ended up scheduling the two rear replacements:
Michelin Pilot Sport A/S Plus Tire 245/45ZR18 96Y
road hazard - $25 a tire.
$571 w/ tax includes mount balance
w/ road hazard $621 out the door.
model information:
Michelin Pilot Sport A/S Plus tires - Reviews, ratings and specs in the Seattle/Tacoma/Bellingham Area - Discount Tire
any concurrences on a good purchase?
