How to Replace Your Tires By Larry Carley copyright Like brake pads,tires wear out and eventually have to be replaced. Most quality brand passenger car tires should last upwards of 60,000 miles with normal driving. Tires can wear out sooner if you drive aggressively,if you don't check the air pressure in your tires and they are underinflated,or if your vehicle has worn or misaligned steering or suspension parts.

The speed rating indicates the maximum speed at which the tire can safely handle without exceeding its design limits. A short burst of speed beyond the tire's maximum speed rating usually won't cause the tire to explode,but sustained driving at speeds beyond the tire's speed rating (especially during hot weather or when carrying a heavy load) does increase the risk of sudden tire failure MaxiDiag Elite MD704. Q - Up to 100mph S - Up to 112mph T - Up to 118mph H - Up to 130mph V - Up to 149mph Z - 149mph and over W - Up to 168mph TIRE SIZING Unless you are replacing your original wheels with aftermarket custom wheels that have a larger or wider rim size,you have to buy replacement tires that are the same size as the original. The tire size is printed on the sidewall of the tire. A 215/60R 16 size means the tire is 215 millimeters wide,has an aspect ratio of 60 (the height of the sidewall as a percentage of the tread width),and fits a 16-inch wheel. Most vehicles that are equipped with antilock brake systems or stability control require replacement tires that are the same size as the original.

The design of the tread has the greatest influence on noise,while the construction of the sidewalls has the largest impact on ride smoothness. Taller softer sidewalls (higher aspect ratio) usually provide the smoothest ride maxisys pro,while shorter stiffer sidewalls (low aspect ratio tires) provide better cornering and handling control.] CHEAP CHINA TIRES Many tires are made in China these days,including tires from many name-brand manufacturers. A tire's country of origin is printed on the sidewall. It should say MADE IN CHINA if that's where it was made. It's difficult to say which tire brands come from which countries because tire manufacturing is a global enterprise. Most tire companies have factories all over the world.

The salesperson may recommend a wheel alignment when you buy new tires. If you old tires show uneven tread wear,or they wore out unusually fast,an alignment check is a good idea. However,if you got 60,000 or more miles out of your old tires,and the tread wear was normal (no shoulder wear or uneven wear),you can probably skip the alignment check.
