I got a flat tire today -- Pirelli 245/45/19. (3,500 miles). Unfortunately the flat was not fixable. I go to purchase a new tire and it turns out the tire is on back order until late July. Called two Maserati dealers and neither one of them had stock. Now, I need to replace the good tire on the front with another brand to get a matching pair. I purchased a pair of Goodyear Eagle GT's. Hopefully I will have no problems with them. I am keeping the other good tire so when the Goodyear starts to wear I will buy a matching Pirelli at that time. I just find it hard to belief than it would take a month to get a matching tire. FYI, TireRack shows back order as well.
