Correct Motorcycle Tyre Pressure: The Complete Guide

Tyre pressure is the cheapest, fastest piece of motorcycle maintenance there is — and one of the most neglected. The right pressure gives you grip, even wear and good fuel economy; the wrong pressure quietly costs you all three. Best of all, checking it takes about a minute and a basic gauge.

What is the correct tyre pressure for my motorcycle?

There's no universal number — it depends entirely on your bike. Typical motorcycle pressures sit somewhere around 28–42 psi (roughly 2.0–2.9 bar), but you must use the values set for your machine. Check the owner's manual or the sticker on the swingarm or chain guard. Don't use the number moulded into the tyre wall.

That tyre-wall figure is the tyre's maximum pressure, not the recommended one — running to it usually leaves the tyre over-inflated. The manufacturer balances comfort, grip and wear for your specific bike and tyre size, so their figure is the one to trust. Front and rear are often different, so set each one separately.

Should I check tyre pressure cold or hot?

Always check cold. That means before you've ridden, or after the bike has sat for at least a few hours. Riding heats the air inside the tyre and pushes the reading up, so a hot check shows a falsely high number. Recommended pressures are quoted for cold tyres, so that's when to measure and top up.

If you've only realised the tyres are low after a ride, you can still add air — but remember the warm reading is inflated by a couple of psi, so don't let a hot tyre fool you into under-inflating. For an accurate set-up, wait until everything has cooled and check again.

How does pressure change for two-up or loaded riding?

When you carry a pillion, luggage or both, the recommended rear pressure usually goes up to support the extra weight. Many bikes list a separate "two-up / loaded" figure in the manual or on the sticker. The front may stay the same or rise slightly — follow the bike's own table rather than guessing.

Running the standard solo pressure with a heavy load over-flexes the tyre, builds heat and accelerates wear. Set it for how you're actually riding that day. Here's how a typical set-up might differ — always confirm against your own bike's figures:

Riding situation	Front	Rear
Solo	Manufacturer's solo figure	Manufacturer's solo figure
Two-up / loaded	Often unchanged or slightly higher	Raised — check the manual
After a long motorway run	Reads high (hot) — recheck cold	Reads high (hot) — recheck cold

How often should I check my tyre pressure?

At least once a month, and always before a long ride. Tyres leak air slowly through the rubber and valve even without a puncture, so a monthly check catches that gradual loss. Add a quick check before any big trip — particularly when you're loaded or two-up — and you'll never set off badly under-inflated.

Building it into a routine is easiest. Pressure naturally fits alongside the other quick visual jobs on your motorcycle maintenance schedule, so check it whenever you give the bike a once-over. A cheap, accurate gauge of your own beats relying on forecourt machines that are often worn out.

What happens if my tyres are under-inflated?

Under-inflation is the most common — and most damaging — pressure problem. A soft tyre flexes more, runs hotter and wears out faster, usually at the edges of the tread. It also reduces grip, makes the steering feel vague and heavy, and quietly worsens your fuel economy because the engine works harder to overcome the drag.

If you've noticed your economy slipping, soft tyres are one of the first things worth ruling out — it's a classic cause covered in our guide to motorcycle fuel consumption. The fix costs nothing but a minute with a gauge, so it's the simplest saving you can make.

Can the wrong pressure damage my tyres or affect handling?

Yes — both under- and over-inflation take a toll. Too little pressure overheats and wears the tyre at the shoulders, hurts grip and can lead to instability. Too much pressure shrinks the contact patch, wears the centre of the tread, and gives a harsh ride with less feel. Neither extreme is safe at speed.

Correct pressure keeps the contact patch the size it was designed to be, so the bike steers predictably and the tyre lasts. Like fresh oil and a clean chain, it's one of those small, regular jobs — much like staying on top of your oil change interval — that keeps everything working as it should.
