I have a 2006 Toyota Highlander and I got four new tires within a month. Last week, I hit a curb and blew out the right front tire sidewall. I currently have the full size spare in its place. I’m wondering if I can/should leave it, or buy a new tire matching the other three. A few points:
The spare, like the car, is six years old.
The car has 230,000 miles on it and this could be the last set of tires, although I hope not.
The tires on the car are fairly new, as is the spare, so tread life shouldn’t be an issue.
The tire in question is not covered by any warranty etc., so I’ll have to pay about $200 to replace it.
