Before replacing your tyres, always consult the vehicle’s owner’s manual and follow the vehicle manufacturer’s replacement tyre recommendations. Vehicle handling may be significantly affected by a change in tyre size or type. When selecting tyres that are different from the original equipment size, see a professional installer to make sure that proper clearance, load-carrying capacity, and inflation pressure are selected. Never exceed the maximum load capacity and inflation pressure listed on the sidewall of the tyre. When replacing tyres, you must maintain the outside diameter and load-carrying capacity of the original equipment tyre. Inflation pressure may need to be adjusted to avoid overloading the tyre. Consult the Tyre & Rim Association Load and Inflation Tables, ETRTO or JATMA standards for correct load and inflation information.
Never fit tyres with less load-carrying capacity than required by the vehicle’s original equipment manufacturer
You must make certain that the replacement tyres have a load-carrying capacity equal to or great than what the original equipment manufacturer specifies.
NOTE: Goodyear manufactured and/or marketed European-Metric passenger tyres and P-Metric passenger tyres are interchangeable as long as they are the same section width, same aspect ratio and same rim diameter.
CAUTION: Never substitute a “Standard Load” (SL) tyre for an “Extra Load” (XL) tyre. If the vehicle was originally equipped with “Extra Load” (XL) tyres, replace those with same sized XL tyres.
Follow these additional guidelines
- When installing two tyres, fit the tyres with the deepest tread depth on the rear axle.
- If radials and non-radials must be fitted to the same vehicle, fit radials on the rear axle.
- Never mix radials and non-radials on the same axle.
- When fitting snow tyres or all-season tyres to performance vehicles, always fit in sets of four.
- It’s not recommended to fit tyres with different speed ratings.
- If tyres with different speed ratings are installed on a vehicle, they should be with like pairs on the same axle.
- The speed capability of the vehicle will become limited to that of the lowest speed rated tyres.
- When changing tyre sizes, always consult a dealer for optimum rim width and carefully check vehicle/tyre clearances.
Don’t overload your vehicle
Check your vehicle’s owner’s manual to determine the load limits. Overloading your vehicle places stress on your tyres and other critical vehicle components. This can also cause poor handling, increased fuel consumption and may cause tyre damage. Never fit your vehicle with new tyres that have less load capacity than shown on the vehicle tyre placard, and remember that optimum rim width is important for proper tyre load distribution and function.
Maintain vehicle suspension & wheel alignment, & balance & rotate your tyres
Lack of rotation, worn suspension parts, under inflation, over inflation, wheel imbalance, and misalignment can cause vibration or irregular tyre wear. Rotate your tyres according to your vehicle manufacturer’s recommendations or at maximum intervals of 6,000 mi./10,000 km.
How to read a tyre D.O.T. serial number
D.O.T. stands for Department of Transportation. This number is located on the lower sidewall of each tyre, showing that the tyre meets or exceeds the Department of Transportation safety standards.
