In the 2010 Prius 5, what does the door jam sticker say is the recommended pressure for the 17" wheels? Anyone? Anyone? I just upgraded to 17s and wanted to have a baseline number to start with--thanks in advance. A L E X Prius 4 Blizzard 17"x8" Gold Enkei RPF1's wearing Michelin Primacy MXM4 215/45R17s iPhone ?
Our Canadian Touring came with the 17" rims, the door decal says 33/32 psi (front/rear). The decal has psi values for both 15" and 17" btw, maybe yours does too? FWIW, I run all four around 34 psi, sometimes bump back up to 36. The low profiles are rougher riding than 15".
33F/32R, any higher psi will result uncomfortable ride. I set mine at 33.2 front, 32.2 rear, my tire pressure gauge can set 0.1 increment.
