Tire Pressure
Tire pressure is the air pressure inside a motorcycle's tires, measured in PSI (pounds per square inch) or bar. Correct tire pressure is one of the single most important factors affecting motorcycle safety, handling, tire wear, and fuel efficiency. Every motorcycle has a manufacturer-specified tire pressure range, typically found on a sticker on the swingarm or chain guard, and in the owner's manual.
Under-inflated tires are dangerous: they generate excessive heat (which can cause a blowout), reduce fuel efficiency, wear unevenly (excessive wear on the edges), and make the motorcycle feel sluggish and vague in corners. Over-inflated tires are also problematic: they reduce the contact patch (less grip), wear unevenly (excessive center wear), and make the ride harsh over bumps.
Check tire pressure when the tires are cold (before riding or after sitting for at least 3 hours), as riding heats up the tires and temporarily increases pressure. Make tire pressure checks part of your pre-ride routine — it takes less than a minute with a simple gauge and can prevent a dangerous situation. A portable tire pressure gauge is one of the cheapest and most valuable tools a motorcyclist can own.

Frequently Asked Questions
How often should I check my motorcycle tire pressure?
Check tire pressure before every ride, or at minimum once a week if you ride daily. Motorcycle tires can lose 1-2 PSI per week naturally, and temperature changes cause additional fluctuations. Always check when tires are cold — before riding or after the bike has been sitting for at least 3 hours. A quick pressure check takes under a minute with a pocket gauge and is one of the most important safety habits you can build.
What happens if I ride my motorcycle with low tire pressure?
Riding with under-inflated tires is dangerous and expensive. Low pressure causes excessive heat buildup, which can lead to a blowout at highway speeds. The tire also wears unevenly (edges wear faster), the motorcycle feels heavy and sluggish in turns, fuel economy drops, and braking distances increase. Even 5 PSI below the recommended pressure noticeably affects handling. In extreme cases, a severely under-inflated tire can unseat from the rim during cornering, causing an instant loss of control.
