There is no single correct tyre pressure for every motorcycle. The right number depends on the specific bike you are riding and on whether you are riding solo or carrying a passenger and luggage. This guide shows you where to find that number and how to measure it accurately — rather than handing you a one-size table, which would be wrong for most bikes.
Where to find bike-specific cold-pressure values
Table of contents14
The correct pressure is set by the vehicle manufacturer, not by the tyre maker and not by whatever number someone quoted you. Two places to find it:
- The owner’s manual. This is the authoritative source. It lists cold pressures for the front and rear tyre.
- A sticker on the bike. Many bikes carry a spec sticker on the frame, under the seat or near the steering head.
The part most riders miss: the manual usually gives two sets of figures — one for riding solo, and an adjusted figure for carrying a passenger or luggage. Michelin describes exactly this layout: the owner’s manual lists cold pressures for solo riding and typically an adjusted pressure for riding with a passenger or loaded with luggage.
If you are touring two-up with large packs and still inflating to the solo figure, your tyres are underinflated for the actual load.
The number on the sidewall is not what you inflate to
There is a pressure figure moulded into the tyre sidewall, and many riders mistake it for the target. It is not. That is the tyre’s maximum pressure — a technical limit, not an operating value.
Michelin states it plainly: the maximum pressure marked on the tyre sidewall is not the operating pressure, and the company strongly advises against using it as one. Stick to the pressures the vehicle manufacturer recommends.
Measuring cold tyre pressure
Tyres heat up as they roll, the air inside expands, and the gauge then reads higher than the true cold figure. Measuring hot and bleeding air off to hit “the right number” leaves you underinflated once the tyre cools.
Michelin’s guidance is to always check cold — before riding, or after the motorcycle has been parked for at least 3 hours.
On frequency, Michelin recommends checking before every ride; at a minimum, every two weeks and before any long journey. For someone on a rented bike that translates into something simple: check at handover, and check again before each long riding day.
How to use a reliable gauge
- Measure cold, under the conditions above.
- Remove the valve cap and put it somewhere secure — it keeps dirt out of the valve, so do not lose it.
- Press the gauge on straight and firmly. A continuous hiss means it is sitting at an angle, air is escaping and the reading will be wrong.
- Read it and compare against your bike’s figure for your actual load situation.
- Add or release air, then measure again. Inflating blind usually overshoots, so work in small steps and re-check.
- Do both wheels. Front and rear nearly always have different specifications.
- Refit the valve cap.
On gauges: the one built into a workshop’s inflator is typically less accurate than a separate hand-held gauge. If you are touring for several days, a small pocket gauge is cheap and worth carrying.
Passenger and luggage load settings
This is the most commonly skipped step on a touring trip. When total load goes up — two riders, packs, panniers — the tyres carry more, and the solo figure no longer fits.
The correct approach: look up the manual’s adjusted figure for a passenger or luggage and inflate to that. Do not add an arbitrary amount by feel, and do not inflate to the sidewall maximum.
On a rental bike without the manual to hand, ask the shop directly for that model’s figure when carrying two people — it is a perfectly normal question and they can look it up.
What the wrong pressure actually does:
- Underinflated makes the bike feel heavy, vague through corners, runs the tyre hotter and wears the shoulders quickly.
- Overinflated shrinks the contact patch, makes the ride harsher and wears out the centre of the tread.
Both cost you grip — which matters most in the wet, as covered in riding a motorcycle in the rain.
When a tyre needs inspection
Pressure is only part of it. Stop and check, or call the rental shop, if you see:
- Pressure dropping quickly after you have just inflated — most likely a nail or a failing valve.
- A bulge or lump in the sidewall. That is structural damage inside the tyre, not a pressure problem. Do not ride on.
- A deep cut or an object embedded in the tread.
- Dense fine cracking in the rubber — the tyre is too old.
- Uneven wear, such as one side worn flat or a dished centre.
- The bike suddenly feeling heavy or weaving compared with the start of the day.
A sidewall bulge and a deep cut are not judgement calls: stop, and change the bike or the tyre.
Checks for a rented scooter
On a rental you usually have no manual. So turn it into two questions at handover:
- “What is the correct tyre pressure for this bike, front and rear?”
- “And what should it be two-up with luggage?”
Then ask them to check it there and then if you have no gauge. A bike sitting at the shop is a cold tyre — exactly the right measuring condition.
Inspecting tyre condition at handover (tread, cracks, embedded objects) has its own step-by-step guide: checking tyres on a rental motorbike.
Frequently asked questions
What tyre pressure should a Wave, Vision or Air Blade run?
There is no single figure for a whole model line, because it varies by version, by front or rear wheel, and by whether you are solo or two-up. Check the manual for that exact bike or the spec sticker on it, or ask the rental shop. A number found online can easily be wrong for the bike in your hands.
Should I inflate to the number on the sidewall?
No. That is the tyre’s maximum pressure, not an operating pressure. Michelin explicitly advises against using the sidewall maximum as your inflation target; follow the vehicle manufacturer’s recommendation instead.
Can I check the pressure right after a ride?
It will not be accurate. A hot tyre reads higher than the true value, so bleeding it down to “the right number” leaves it underinflated once cool. Michelin recommends always checking cold — before riding, or after the bike has been parked for at least 3 hours.
How often should I check?
Michelin recommends checking before every ride, and at a minimum every two weeks and before any long journey. On a rented bike that means at handover and before each long riding day.
How much extra should I add for a passenger?
Exactly what the owner’s manual specifies for a passenger or luggage — do not estimate. Without the manual, ask the rental shop for that model’s two-up figure.
At handover
Ask Mr Tú for the correct tyre pressures for your bike, both solo and two-up with luggage, and have them checked while the tyres are still cold before you leave.
