Would not doubt it although the prices for these tires have been going up gradually for years.
My dear all Bridgestone "aficionados",
i was able to order through my last Ferraridealer (i brought at his dealership 2 F355 GTB's, 1 Maranello F 575M F1,and the last two F. i had, two F 430 GTB's)
two set's of rears in 345/35 ZR 19 size by phone, and few hours later he could confirm by phone, that it takes 2 days for delivery.
The prices here in switzerland also went up, as crude oil is used to produce these tyres for our cars, and the crude oil prices have gone up since the Ferrari Enzo did come out on the Geneva salon d'auto (MOTOR SHOW; ALWAYS IN BEGIN OF MARCH EVERY YEAR), many years ago.
I do keep my swiss tumbs up, that my US F GT owner's have the patience to get again the wonderful tyres, maybe you have to go with orders through serious tyredealers and not to try to order through the internet ( and then maybe get offered one's with production code from WXYZ, very old as we have seen here in this section!!)
sincerely
