Frequently Asked Questions
How can I check my tyres for wear problems?
Tyres often give their owners signs of problems in plenty of time to have them corrected. Learn to "read" these early warning signs and you can prevent many wear problems that shorten tyre life by thousands of miles.
Wear On Both Edges: UNDER INFLATION.
If a tyre looks like this, it may be under inflated. The worst enemy a tyre can have is too little inflation pressure. Under inflation reduces treadlife through increased tread wear on the outside edges (or shoulders) of the tyre. It also generates excessive heat which reduces tyre strength. Finally, it reduces fuel economy through increased rolling resistance (soft tyres make your vehicle work harder). Check your tyres regularly for proper inflation. Abnormal tyre wear may also be due to misalignment or mechanical problems. Many Goodyear retailers can assist in diagnosis and repair.
Wear In Center: OVER INFLATION.
When a tyre is over inflated, the center of the tread bears most of the load and wears out faster than the outside edges. Uneven wear reduces the useful life of a tyre. Check your tyres regularly for proper inflation. Abnormal tyre wear may also be due to misalignment or mechanical problems. Many Goodyear retailers can assist in diagnosis and repair.
Wear On One Side : MISALIGNMENT
This is caused by erratic scrubbing against the road. The solution is toe-in or toe-out alignment corrections.
Proper inflation is the single most important part of tyre care. The inflation pressure on the side of the tyre is the MAXIMUM operating pressure. It is not necessarily the right inflation for your vehicle. Always use the inflation recommended by the vehicle manufacturer. You can find it in your owner's manual, posted on the edge of the driver's door, on a door post or on the inside of the glovebox door. Always check inflation when tyres are COLD: when the vehicle has been driven less than a mile or one hour or more after driving. Use a good quality tyre gauge. Note: It's natural for radial tyres to have a slight bulge in the sidewall at their proper inflation pressure. Check or adjust inflation every few weeks, before any long trip or if traveling with a heavy load. And don't forget to check the spare. Your Goodyear retailer can answer any questions you may have about tyre inflation.
Is it safe to repair a flat tyre?
If a tyre loses all or most of its air pressure, it must be removed from the wheel for a complete internal inspection to be sure it's not damaged. Tyres that are run even short distances while flat are often damaged beyond repair. Most punctures, nail holes, or cuts up to 1/4 inch -- confined to the tread -- may be satisfactorily repaired by trained personnel using industry-approved methods. Don't repair tyres with tread punctures larger than 1/4 inch, or any sidewall puncture. Also, never repair tyres which are worn below 1/16 inch tread depth. Your best bet is to make sure your spare tyre is always ready to do the job. Check it regularly for proper air pressure and be sure that it is in good shape. If your car is equipped with one of the several types of temporary spares, be sure to check the spare tyre's sidewall for the correct inflation pressure, speed, and mileage limitations. See Goodyear Retailer for expert tyre repair.
My tyre has gone flat. Is this covered by my Goodyear Limited Warranty?
Due to the variety of causes for air loss, this question can only be answered by an authorized Goodyear Retailer.
Some common causes of sudden or slow air loss:
Isn't it easy to mount a tyre on a wheel? Can't I do it myself?
Never try to mount your own tyres. Tyre mounting is a job for the people who have the proper equipment and experience. If you try to do it yourself, you run the risk of serious injury to yourself as well as possible damage to the tyre and rim.
Should I rotate my tyres?
Regular and proper tyre rotation promotes more uniform wear for all of the tyres on a vehicle. All season tyres should be rotated in a "modified X" pattern, meaning only the tyres being moved to the drive axle are crossed to the opposite side of the vehicle.
The remaining two tyres are moved from the drive axle to the free rolling axle, remaining on the same side of the vehicle. This method of rotation helps promote a more even and uniform treadwear pattern for all four tyres.
The only exception to this would be the use of "directional" tread design tyres such as our Aquatred II or some of our Eagle line high performance tyres. These tyres would remain on the same side of the vehicle and be rotated straight forward and straight back.
If you have a four-wheel drive vehicle, we recommend crossing both pairs of tyres to their new axle positions. We recommend tyre rotation at least every 6,000 miles. Four-wheel drive vehicles may require rotation even sooner such as every 4,000 miles. Check your vehicle owner's manual for the manufacturer's rotation recommendations. If no rotation period is specified, tyres should be rotated every 6,000 to 8,000 miles. The first rotation is the most important. When tyres are rotated, inflation pressures must be adjusted to the vehicle manufacturer's recommendations. Uneven tyre wear may also be due to misalignment or mechanical problems. Many Goodyear retailers can provide expert diagnosis and repair.
What is alignment?
A vehicle is said to be properly aligned when all suspension and steering components are sound and when the tyre and wheel assemblies are running straight and true. Proper alignment is necessary for even tread wear and precise steering. Uneven front-or rear-tyre wear, or changes in your vehicle's handling or steering response (i.e. pulling to one side) can indicate misalignment. Many vehicles today are equipped with rear suspensions that can be adjusted for alignment. Your vehicle may need a "front-end" alignment or a "four-wheel" alignment, depending on the symptoms you are experiencing. The moderate cost of having your vehicle aligned can more than pay for itself in tyre mileage, performance and comfort. Goodyear retailers provide expert alignment and suspension service.
What should I do if I notice a vibration?
Vibration is an indication that your car has a problem that needs attention. The tyres, steering system and suspension system should be checked to help determine the possible cause and correction of the vibration. If left unattended, the vibration could cause excessive tyre and suspension wear. It could even be dangerous. Goodyear retailers offer expert diagnosis and repair.
Why do my tyres need to be balanced?
Properly balanced tyres are important for driving comfort and long tyre life. Unbalanced tyres can cause vibration, resulting in driver fatigue, premature tyre wear and unnecessary wear to your vehicle's suspension. Tyres should be balanced when they are mounted on wheels for the first time or when they are remounted after repair. Tyres should be rebalanced at the first sign of vibration or "shimmy." Vibration may also be due to misalignment or mechanical problems. Many Goodyear retailers can provide expert diagnosis and repair.
Do my new tyres require any special treatment?
Your new tyres will probably feel different from the tyres that were replaced. Drive carefully as you become familiar with their performance and handling. Take special care when braking, accelerating, cornering, or when driving in the rain, because these are the times when the differences will be most noticeable.
How do I know when I need new tyres?
Many tyres have tread wear indicator bars molded into the tread. When the tread is worn down to where you can see a solid bar of rubber across the width of the tread, it is time to replace the tyre. Here's another simple test you can perform to measure tread depth on your tyres. Place a penny into a tread groove with Lincoln's head upside down and facing you. If you can see the top of Lincoln's head, it's time to visit a Goodyear retailer for a new tyre.
How long should my original equipment tyres last?
Goodyear does not offer a written mileage promise on any tyres supplied as original equipment. Due to the variety of styles, construction features, treat compounds, vehicle applications, geographical conditions and driving habits, it is difficult to provide a specific mileage expectancy.
However, any tyre wear concern should always be presented to your local authorized Goodyear retailer for further evaluation.
Many of our authorized retailers offer specific mileage warranties on several lines of tyres sold as replacement tyres, including some tyres that are used as original equipment. These mileage warranties are administered based on the retail outlets verification of proper tyre maintenance having been performed.
Must I replace my present tyres with the same size tyres?
Never choose a smaller size than those that came with the car. Tyres should always be replaced with the same size designation -- or approved options — as recommended by the vehicle manufacturer or Goodyear retailer.
Should I "mix" tyre types on my car?
Tyres of different size designations, constructions, and stages of wear may affect vehicle handling and stability. For an ideal all-around performance, it is recommended that all tyres be of the same size, construction (radial,non-radial) and speed rating. If tyres of different speed ratings are mounted on a vehicle, the same size, type and speed ratings need to be placed on the same axle, the tyres with the lower speed rating will be the determining factor for permissible tyre related vehicle speed. Never mix radial and bias-ply tyres on the same axle. Get specific information from your Goodyear retailer.
When buying just two new tyres, should they be put on the front or rear?
When radial tyres are used with bias or bias belted tyres on the same car, the radials must always be placed on the rear axle. Never mix radial and bias-ply tyres on the same axle. When you select a pair of replacement tyres in the same size and construction as those on the car, we recommend you put them on the rear axle. A single new tyre should be paired on the rear axle with the tyre having the most tread depth of the other three.
Can my driving habits affect the life of my tyres?
They certainly can. Here are some tips to increase the life of your tyres:
