TIRE PRESSURE SHOULD BE CHECKED & MAINTAINED FREQUENTLY. UNDERINFLATED OR OVERINFLATED CAN CAUSE TIRE WEAR PROBLEMS & WILL EFFECT ALIGNMENT OF VEHICLE. GAS MILEAGE,CAN BE AFFECTED, & ALSO VERY IMPORTANT ARE GEAR TRAIN RATIO PROBLEMS AS PER TRANSMISSION & FINAL DRIVES OR REAR TYPES. & CAN ALSO EFFECT COMPUTER /SENSOR ISSUES & OR SPEEDOMETER BEING OFF. EVEN AS SMALL AS A FEW POUNDS CAN MAKE A DIFFRENCE AFTER RESEARCH DONE. ALSO VERY CRITICAL ON 4X4 TYPES. SO MAKE SURE YOUR TIRES ARE PROPERLY MAINTAINED NEXT TIME YOU ARE SERVICING YOUR VEHICLE. A SIMPLE GAUGE CAN BE PURCHASED IN ANY AUTO PTS STORE. A SMALL ANALOG FACE GAUGE IS EASY TO READ & ABOUT YOUR BEST BET.

THANKS FOR BROWSING
