2015 Volvo S60 235/40 R19 tire blowout replacement
On my S60 T5 platinum sport the tires are 235/40 R19 96V which is apparently a hard size to get, and expensive too - apparently 19" tires cost more than many 18 or even 20s.
Had a blowout while out of state and called my Volvo dealer to find out that there is no spare. The tire actually separated at the tread, so fix a flat was not a option - and anyway, from past experience on my Carrera 4 that fix a flat stuff can leak from your tire to where it will leak constantly and corrode away/damage at least aluminum rims.
Even though this was no small town, a major city, I had to phone five different tire dealers, new and used, before I found a national chain with the correct tire, but not the same brand. I worked out a deal with them to sell me the Bridgestone tire and exchange it free of charge for the Pirelli that is original equipment on my car at another branch of their chain when I got back home.
