What is the correct tire pressure on a 2005 Nissan Altima with all season tires Sticker on doorframe does not answer this question. Tire max is 44 owner's guide says 29 but this seems too low?

Answer 1

Tire air pressure? Listen to what Pirelli Tire's Limited Warranty has to say about it. Recommended tire inflation pressures for your vehicle can be found either in your vehicle owner's manual or your vehicle's tire placard or in the manufacturer's data book. Correct pressures are related to loads, speeds and vehicle handling and are vital for even braking, maximum traction and good tire life. Under no circumstances should your tire's cold inflation pressure be less than that indicated in your vehicle owner's manual or on your vehicle's tire placard or higher than the maximum cold inflation pressure molded onto the tire's sidewall. Under-inflation causes excessive flexing, deterioration of the tire and rapid wear of the tread edges. Over-inflation results in an uncomfortable ride, a reduced area of tire contact with the road surface (i.e. smaller tire footprint), higher susceptibility to impact damage and rapid wear on the tread center. Inflation pressure must be checked at least once a month and should be checked only when the tire is cold or before it has been driven. Driving even a short distance (1 mile or 2 to 3 minutes) causes tires to heat up and the pressure to increase approximately 4 p.s.i. In case it is necessary to adjust the air pressure in the tires that have been driven, the air pressure should be increased to a guage reading of 4 p.s.i. high than the recommended cold inflation pressure. For example only:Gauge reading of hot tire 27 p.s.i. Recommended cold inflation pressure 26 p.s.i. Desired guage reading of hot tire 26 p.s.i. + 4 p.s.i. = 30 p.s.i. Therefore add 3 p.s.i. Check cold inflation pressure on tires, at least by the next day. never reduce or "bleed" air from hot tires since your tires will then be under-inflated when they cool down.Always use a reliable pressure gauge.
