Should I use the PSI printed on the tire sidewall?

No. The number on the sidewall is the tire's maximum pressure, not the recommended pressure for your bike. Use the figure from your owner's manual or the label on the bike.

How often should I check motorcycle tire pressure?

Before every ride is the safest habit, and at the very least weekly. Motorcycle tires are small, hold little air and can lose pressure slowly with no visible sign.

Do front and rear tires use the same pressure?

Usually not. Most bikes call for different pressures front and rear, and many also list one set for solo riding and another for a passenger or a heavy load.

Is it OK to ride on a slightly low tire to a gas station?

Short and slow, yes, if the tire is only a few PSI low and has no damage. Do not ride on a tire that is flat, visibly squashed, or leaking fast.

Motorcycle tire pressure: how to find and check the right PSI

The right motorcycle tire pressure is the cold PSI listed in your owner's manual or on the label on the bike, usually on the swingarm, frame or under the seat. For many street bikes that is somewhere between about 28 and 42 PSI, with the rear often higher than the front. The number printed on the tire's sidewall is the tire's maximum, not the recommended setting.

Pressure is the cheapest and most important tire setting you control. This guide shows where to find the right number, how to check it and what changes it.

Where to find the right motorcycle tire pressure

Look in this order:

Owner's manual. The specifications section lists front and rear pressures, often for solo riding and for a passenger or full load.
Label on the bike. Many bikes have a sticker on the swingarm, frame, chain guard or under the seat.
Manufacturer or dealer. If the manual is gone, a dealer for your brand can look it up from your VIN or model year.
The tire maker. Tire brands publish fitment guidance for some tire and bike combinations, which is useful if you run a different size than stock.

Sidewall number vs recommended pressure

The maximum pressure molded into the sidewall is the tire's limit. It is not the number your bike was tuned for. NHTSA's tire guidance makes the same distinction for cars: it points to the vehicle's own label for the proper pressure, not the tire. The same logic applies to bikes.

Typical ranges by bike type

These are common patterns, not a replacement for your manual.

Bike type	Front (PSI)	Rear (PSI)
Sport or supersport	32 to 36	36 to 42
Cruiser	30 to 36	36 to 40
Touring	36 to 42	36 to 42, higher with load
Adventure or dual-sport (street)	28 to 36	32 to 42
Scooter	25 to 30	28 to 36
Off-road tires	12 to 20	12 to 20

If you ride a bike with tubeless tires and cast wheels, your manual number holds. If you run tubes, tire changes or aftermarket tires, check for a revised figure.

How to check motorcycle tire pressure

Checking takes two minutes. The Motorcycle Safety Foundation's T-CLOCS checklist lists air pressure under tires and says to check it cold and adjust for load. NHTSA's rider guidance also includes tire pressure and tread depth in its list of pre-ride checks.

Check cold. Before you ride, or after the bike has sat for at least three hours, which is how NHTSA defines cold.
Use a good gauge. A quality dial or digital gauge is better than the gas station pump gauge, which is often off.
Remove the valve cap and press the gauge on straight and firmly until the reading steadies.
Compare with spec. Add air or let some out with the gauge's bleed button.
Refit the cap. It keeps dirt out of the valve.
Check both tires. Do the front and rear every time, since one often drops first.

A small portable inflator or a hand pump that fits under the seat is worth owning. A tire pressure monitoring system (TPMS) can also help, but still confirm with a gauge now and then.

What changes tire pressure

Tire pressure is not fixed. It shifts with several factors.

Temperature. Air pressure changes with temperature. As a rough rule of thumb, tire pressure changes by about 1 PSI for every 10 degree Fahrenheit shift in air temperature. Check more often when the weather swings.
Riding. Pressure rises as tires warm up. Do not let air out of a hot tire to hit the cold number.
Load. A passenger, luggage or a trailer usually means you need more pressure in the rear, and sometimes the front. Your manual lists the change.
Natural leakage. Tires lose a little air over time even without a puncture, and small motorcycle tires are sensitive to small losses.
Altitude. Gauges read the same, but a long climb or descent can change the cold pressure you start with.

Signs of wrong tire pressure

Too low

Heavy, slow or vague steering
The bike feeling like it wants to fall into turns
Wider, uneven wear on the shoulders of the tire
Excess heat and a higher risk of damage or a blowout at speed
Reduced fuel economy

Too high

A harsh, bouncy ride and less grip
Wear down the center of the tread
Reduced contact patch, which hurts traction in the wet

Underinflation does more harm than overinflation, but both reduce control. NHTSA lists signs of irregular wear from underinflation or overloading as a reason to replace a tire.

How does tire pressure affect handling and safety?

A tire only touches the road with an area roughly the size of your palm. Pressure decides how that patch is shaped. Too little and the sidewalls flex too much and heat up. Too much and the tire is stiff and slides more easily.

For that reason, pressure should be part of your routine even when nothing seems wrong. Slow leaks from a nail or a failing valve stem are common, and they are easy to miss without a gauge.

Can I adjust pressure for different conditions?

A small adjustment is common, especially for track days or off-road riding, but stay close to the manufacturer's range for road riding. Never go above the tire's maximum or below the lowest value the tire maker allows. If you are changing pressures for performance, change by 1 or 2 PSI at a time and note how the bike feels.

New or aftermarket tires may have their own recommended pressure. Our guide to choosing motorcycle tires for your riding style explains how tire type affects the numbers you run.

Setting pressure for a passenger or luggage

When you add weight, the tire flexes more, so many manuals call for a higher rear pressure, and sometimes a higher front too. Read that section of the manual before a long trip, and set the new pressure while the tires are cold. After the trip, return to the solo number. Leaving the bike at the loaded setting for daily commuting can make the ride harsher and wear the center of the tread faster.

If you tow a trailer or carry heavy hard luggage, do not guess. Check the maximum load listed for your bike and make sure the combined weight of rider, passenger and gear stays inside it.

When to see a mechanic

Bring the bike to a shop if:

A tire keeps losing pressure after you fill it
You find a nail, bulge, cut, crack or exposed cords
The tread is worn to the wear bars or the tire is older than your tire maker recommends (our tire date code guide shows how to read the age)
The bike wobbles or pulls to one side
A valve stem is cracked or leaking
You see uneven wear that does not improve with correct pressure

Do not ride on a tire that has lost a lot of air or has visible damage. A shop can patch or replace the tire, check the wheel and balance it. If you want to compare local options, search motorcycle repair shops in Phoenix or browse our national motorcycle tire services page. When it is time for new rubber, our tire replacement cost guide shows what to budget, and the maintenance schedule covers how often to check other items.

Quick routine

Check both tires cold before every ride, or at least weekly.
Use the manual or label PSI, not the sidewall maximum.
Adjust for a passenger or heavy load as your manual says.
Inspect tread, sidewalls and the valve stem each time.
Keep a gauge you trust and a small inflator on hand.
