Tuesday, you may remember, I discovered something that is generally referred to as a "road hazard," the sort of thing that turns a tire into basically a paperweight for the Amazing Colossal Man.
That afternoon, about two, I contacted the Tire Rack and ordered a replacement. It arrived in the city just after noon yesterday, and was installed that afternoon.
In the interim, I got some experience with the spare, which apparently had never been on the ground before. To everyone's surprise, it was a full-size tire, not one of those shrunken-donut jobs, and it was a fairly substantial name: a Toyo Proxes. The previous owner, I surmise, had sprung for five of the Toyos when the OEM tires (probably Bridgestones) wore out, and eventually replaced four of them with BFGoodrich Touring T/As.
Which, I suppose, invites a question: how long should a set of tires last? My current Dunlops are considered "High-Performance All-Season Tires," which the Tire Rack explains as follows:
You want all-season versatility (including light snow traction) to drive your sports coupe or sedan in all weather conditions.
Branded with the M+S symbol, these low profile tires are designed to provide year-round traction (even in light snow) through tread designs and compounds that remain flexible in the cold weather to help blend all-season traction with good handling.
In Gwendolyn's size (215/55VR16), these tires carry a Uniform Tire Quality Grade of 460 AA A. This only hints at tread life: a tire rated 200 is supposed to outlast a tire rated 100 by a factor of two, but how long does the 100-rated tire last? I'm hoping for four years/45,000 miles on this set. (The longest I've ever managed to keep a set of tires going was right around 50k, on Bridgestone's lower-end Turanzas.)Posted at 3:01 PM to Driver's Seat
