What You Need To Change A Tire

Before starting time the process of replacing your tires, always consult your vehicle's owner'south manuals and their tire replacement recommendations and restrictions. The owner'due south manual will also contain additional important tire care and maintenance. Some other source of information from the vehicle manufacturer regarding tire size and loading information as well as recommended tire aggrandizement specifications can be establish on the vehicle tire placard located on the driver'due south door border or door post.

Replacing Your Tires

The tread depth on all tires wears down while driving and the tires volition eventually need replacing.

How quickly a tire will need replacing depends on various things, such as driving habits (altitude traveled, speed, severity of braking & cornering, etc.), where you live, and how well the tires are maintained on your vehicle.

Signs When to Change Tires

• Tread wearable bars: All rider and light truck tires have at least six tread clothing bars (as well known equally treadwear indicators) located in the major tread grooves and spaced approximately every bit effectually the circumference of the tire. The tread wear bars are raised smooth molded narrow rubber strips that are two/32" (1.6mm) in acme and enable a vehicle owner to decide visually when the tire has worn to a tread depth of 2/32" (1.6mm) – when the tread clothing bar located in the tread groove is flush with the surface of the tread, the tire is worn to 2/32" (1.6mm) and should be replaced.
• Uneven wear patterns: Learn how to measure your tire tread depth and check for uneven or abnormal wear patterns that may bespeak a vehicle alignment or mechanical effect that needs attention.
• Bulges or blisters on the tire's sidewall: These tin lead to tire disablement and should exist inspected by a tire professional.
• Low Tire Pressure: Information technology is recommended that a tire that has been run flat or severely underinflated exist inspected by a tire professional before being put back into service.
• Sudden ride disturbance or vibration: A ride disturbance may exist an indication of possible tire damage or a vehicle mechanical upshot and it is recommended that the vehicle and tires be inspected by a mechanic or tire professional.

Ownership Tips for Tire Replacements

• Replace all four at once: Vehicle manufacturers recommend replacing all iv tires on the vehicle at the same time. Replacing all iv tires at once helps to maintain optimum vehicle functioning and handling. If less than all 4 tires are replaced, information technology is recommended additional guidelines be followed. When replacing only two tires of the same size and construction as those on the vehicle, it is recommended to install the tires with the deepest tread depth on the rear beam to prevent a possible oversteer situation. A unmarried new tire should be paired on the rear axle with the tire having the deepest tread depth of the other three tires. Read additional information on where to install less than four ii tires on your vehicle.
• Install tires on the rear beam: As two new tires are installed on your machine, the new tires should ever be installed on the rear axle, then motion the existing partially worn tires to the front beam. Placing the new tires on rear axle can help to maintain control on wet roads. Read more about installing tires on the rear axle.
• 4WD and AWD Vehicle Guidelines: Always cheque and follow the recommendation in the vehicle owner'due south manual, fifty-fifty small variances in outside diameter may cause bulldoze-train damage or mechanical malfunction. If no instructions for tire mixing appear in the vehicle owner's manual, follow these guidelines:
  • Practise not mix sizes.
  • Practise not mix radial and bias-ply constructions.
  • Do not mix tread patterns such equally all-flavor and all-terrain.
• Unlike speed ratings: Information technology'southward not recommended to fit tires with different speed ratings. However, if they are fitted with dissimilar speed ratings they should be installed with similar pairs on the same axle. The speed-adequacy of the vehicle will go that of the lowest speed-rated tire. Refer to your owner'due south manual or the vehicle tire placard for specifications on tire speed ratings.
• Load-conveying capacity: Make sure replacement tires have an equal or greater load-carrying capacity to the original equipment tires.

Never Fit Tires with Less Load-Carrying Chapters Than Required

Many vehicles, such as large rider vans, require Load Range E tires. Fitment of a tire with less carrying capacity, such every bit a Load Range D, is not immune. In other cases, tires of the same size may carry dissimilar load indexes in the service clarification. Yous must brand certain the replacement tires fitted to the vehicle take a load-carrying capacity equal to or greater than what the original equipment manufacturer specifies.

NOTE: Goodyear manufactured and/or marketed European-Metric passenger tires and P-Metric passenger tires are interchangeable as long as they are the same section width, aforementioned aspect ratio and same rim bore.

CAUTION: Never substitute a "Standard Load" (SL) tire for an Extra Load (Twoscore) tire. If the vehicle was originally equipped with "Extra Load" (XL) tires supplant those tires with similar sized XL tires.

Warning

Earlier you replace your tires, always consult the vehicle owner's manual and follow the vehicle manufacturer's replacement tire recommendations. Vehicle handling may exist significantly affected by a change in tire size or type.

When selecting tires that are different from the original equipment size, run into a professional installer in order to brand sure that proper clearance, load-carrying chapters, and inflation pressure are selected. Never exceed the maximum load capacity and inflation pressure listed on the sidewall of the tire. Ever drive safely and obey all traffic laws. Avoid sudden, sharp turns or lane changes. Failure to follow this warning may result in loss of control of the vehicle, leading to an blow and serious injury or death. When replacing tires, you must maintain the outside bore and load-carrying capacity of the original equipment tire. Inflation pressure may demand to be adjusted to avoid overloading the tire. Consult the Tire & Rim Clan Load and Aggrandizement Tables, ETRTO or JATMA standards for correct load and inflation information.
