The max psi for the general altimax rt43 tire size 235/55R18 is 51 psi, but I wanted to know what the best tire pressure for them is in the summer? Should I air them up to 51 psi? Thanks!

    Tire pressure listed on the sidewall of your tire is NOT a recommended tire pressure for your vehicle - it is a maximum tire pressure your tire can be inflated to carry tire's maximum load. Inflate your tires to the recommended tire pressure as suggested by your vehicle's manufacturer.

    Thank you for getting back to me Serge! Where would I find that information? I bought my GMC Terrain used, from a Toyota dealership. Would the dealership where I bought it from be able to tell me? Thanks!

    Recommended tire pressure is usually listed on the side of the driver's door, inside the glove compartment, or in your vehicle's manual. Dealership might also help you with that. Check it here 2011 GMC Terrain Tire Pressure.
