The cx-5 recommends 36 psi for all 4 tires for the stock wheels that come with the car, I have the toyos 19in with the GT version. I just got 19in winters put on this weekend, and the max psi rating for the tires is 40 - the blizzak dm-v1s. I set the pressure to 36 after getting home from having the shop swap out my wheels/tires. Is that too much? The winters are the same exact size 225/55R19 as the stock tires, so it would seem that having them at the same pressure makes the most sense?
