Out-of-balance tyres will cause any vehicle to vibrate at certain speeds, usually between 50 and 70 mph.
A tyre is out of balance when one section of the tyre is heavier than the others. One ounce of imbalance on a front tyre is enough to cause a noticeable vibration in the steering wheel at about 60 mph.
Most high quality tyres will hold their balance fairly well and go out of balance very gradually. If you notice a vibration that wasn't there the day before, it is possible that one of the lead balancing weights fell off. If you feel the vibration mostly in the steering wheel, the problem is most likely in a front wheel. If the vibration is mostly in the seat, the problem is probably in the rear.
Symptoms which indicate your wheels are out of balance:
• Vibration through your steering wheel
• Vibration through your seat
• Vibration through the floor
• Vibration on all of the above only at certain speeds
If you have noticed any of the above we advise you contact us at your earliest opportunity for a wheel balancing check.
