I bought a pair of Yokohama tires for the front wheels of my 2005 Cadillac STS last year. Now that I need rear tires, I see that the size is different and Yokohama does not make a tire in the “correct” size. So the quandary is whether to buy the matching tire in a slightly smaller size OR go with a different manufacturer in the proper size.
The correct tire is a P255/45/17. I can get a P245/45/17 instead. The width is .39" less, height is .18 less (4%), diameter .36" less (1.4%), 809 rev per mile rather than 799. Continental makes the correct tire in their DWS 06 line. That’s also a good tire at about the same price.
What do you think? Do I flip a coin?
