The original equipment is 225/55 r19. I got the front wheels replaced a month ago with the right size michelins. Since i was out of commission yesterday, i had my buddy get the rear wheels replaced.

Unfortunately he got 255/55r19 tires instead. I only noticed it today while I going to work. He left the originals with the tire shop. Im due for a long drive in 8 hours and I dont know if the tire shop is open on a sunday (eastern hemisphere).

How screwed am I?

Car is 2014 AWD mazda CX5
