MG Recommended Tire Pressure

Check MG tire pressure charts with recommended tire inflation pressures for MG tires to improve fuel efficiency, extend tire life and drive safely. Select your MG model or year.

MG MGB Tire Pressure

Recommended tire pressure for MG MGB tires.

It is vital to maintain proper tire inflation pressures for MG tires. Low tire pressure will result in tire underinflation while high tire pressure will result in tire overinflation, which can reduce fuel efficiency, lead to uneven tire tread wear and decrease tire life, compromise tire safety and cause tire blowout. Check MG tire pressure regularly, and monitor MG tire inflation pressures to avoid driving with overinflated or underinflated tires.

Tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not the recommended tire pressure for MG. Use MG recommended tire pressure settings listed on the tire pressure chart found in MG owner's manual, on a tire placard on driver's door or door jam, inner trunk lid, in the console or on the fuel door. Recommended tire pressure for your MG tire sizes will be listed in one of the following pressure units: psi (pounds per square inch), bar or kPa (kiloPascals). Pay attention as your MG may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your MG tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.

If you replace MG original equipment tires or switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for your new MG tires. MG tires with the same load index, regardless of tire size, may carry the same load, but may require substantially different inflation pressures. Tire load index may not be used independently to determine replacement tire acceptability for load capacity. An equal or greater load index does not always correspond to equal or greater load capacity at all inflation pressure settings. MG replacement tires must have equal or greater speed rating compared to the original equipment tires if your MG speed capability is to be maintained. It is recommended that tire installers refer to the MG owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your MG replacement tires have a lower speed rating than the original equipment tires, your vehicle’s speed must be restricted to that of the replacement tires. Original equipment tires that come on your MG will have the proper tire load index, so use same or higher load index when choosing replacement tires. Tire load index tells you how much weight your tire can carry. Putting too much weight on your tires will overload them, and can cause premature tire wear, tire damage or even tire blowout. Refer to your MG manual to find its original equipment tire sizes and load ratings. Always refer to the MG owner’s manual for any specific safety advice regarding the application of MG replacement tires.

MG tire pressure may fluctuate with ambient temperatures, so check MG tire pressure when ambient temperatures change. In winter when temperatures drop, MG tires may deflate by approximately 1 psi for each 10 degree Fahrenheit decrease in temperature. Maintain proper MG winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

MG tire pressure should be checked when tires are cold, after your vehicle has not been driven for at least three hours. It is best to check your tire inflation pressure in the morning, after the vehicle has been parked overnight, using a reliable tire pressure gauge.

If your MG is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure MG tire pressure sensors are working properly to stay alert and enjoy a safe ride. If your tire pressure warning light is on, check front and rear tires to make sure they are properly inflated.

What is the recommended tire pressure for MG?
Recommended tire pressure for MG is determined by the manufacturer based on your vehicle's characteristics and original equipment tire sizes. Select your MG year or model to get recommended tire inflation pressures for MG tires.

Where do I find recommended tire inflation pressures for MG?
You can find your MG recommended tire pressure in MG owner's manual, on a tire placard on driver's door or door jam, inner trunk lid, in the console or on the fuel door. Recommended tire pressure for MG will be listed in psi, bar or kPa.

How to check MG tire pressure?
Proper MG tire inflation is essential to the overall tire performance and safety. To check tire pressure for MG you will need to know its recommended tire pressure and a tire pressure gauge. Check cold inflation pressures in MG tires with tire pressure gauge and adjust to MG recommended tire inflation pressures as needed by adding or releasing air. Make sure to check tire inflation for your MG regularly to ensure safe and comfortable drive.

Is my MG equipped with a tire pressure monitoring system (TPMS)?
If your MG is made after 2007, it should be equipped with tire pressure monitoring system. To confirm if your MG has TPMS, turn on the ignition without starting the engine. If a tire icon with an exclamation sign lights up on your dashboard, your MG is equipped with TPMS. You can also check MG owner's manual for more information.

Why is MG tire pressure warning light on?
If your MG is equipped with Tire Pressure Monitoring System (TPMS) it will alert you when tire pressure is too low and your tires could be underinflated, which can lead to uneven tire wear or can cause tire failure. If MG low tire pressure warning light is on, check all MG tires for low air pressure and inflate tires to the recommended tire inflation pressures. Keep in mind that Tire Pressure Monitoring System does not replace routine tire pressure check and maintenance.

How do I reset MG tire pressure monitoring system?
To reset tire pressure monitoring system for MG, make sure front and rear tires are inflated to the recommended levels. Refer to your owner's manual on how to reset MG TPMS.

What is recommended winter tire pressure for MG?
Recommended tire pressure for MG is the same for any season, but you may inflate your MG tires 3 to 5 psi above the recommended tire pressure set by the manufacturer to compensate for lower temperatures during winter. Make sure to check your MG tire pressure more often in the winter to keep tires properly inflated for a safe ride on snow and icy roads.
