Disclaimer & Terms of Use
Last updated: May 2026 · Effective immediately
By using tirepressure.guide, tyrepressure.guide, or airpressure.expert you agree to this Disclaimer in full. If you do not agree, please stop using the site immediately.
Overinflating a tyre can cause tyre blowout at high speed, resulting in serious injury or death. A tyre blowout while driving can cause sudden and complete loss of vehicle control. At highway speeds this is frequently fatal.
⚠️ Never exceed the maximum pressure printed on the tyre sidewall. That number is the structural limit of the tyre — not a recommended driving pressure. Exceeding it risks immediate or delayed tyre failure.
⚠️ Never inflate using an industrial air supply without a calibrated gauge. Industrial compressors can over-pressurize a consumer tyre in seconds.
⚠️ Never stand directly over or in front of a tyre while inflating. In the event of sudden failure, tyre debris and the wheel rim become high-velocity projectiles.
Underinflated tyres are the leading cause of tyre failure. A tyre that is significantly underinflated builds up excessive heat through flexing, which can cause a sudden blowout with no warning.
⚠️ Underinflated tyres reduce braking performance, increase stopping distances, and cause unpredictable handling — especially in emergency situations.
⚠️ A tyre can look visually normal and still be dangerously underinflated. Always verify pressure with a calibrated gauge — never judge by eye.
Always use the pressure specified by your vehicle manufacturer — not this website. Your manufacturer's recommended pressure is found on a sticker inside the driver's door jamb, in the glove box, or in the owner's manual.
Check tyre pressure when tyres are cold — before driving or at least 3 hours after parking. Driving heats tyres and increases pressure by 4–6 PSI (0.3–0.4 BAR), giving a false reading.
Check pressure at least once a month. Tyres naturally lose approximately 1–2 PSI per month under normal conditions. Temperature changes also affect pressure: for every 10°F (5.5°C) drop in temperature, tyres lose approximately 1 PSI.
1. General Information Only
All tyre and ball pressure values on this site are provided as general reference information based on publicly available manufacturer guidelines, official sports regulations, and industry standards. The correct pressure for your specific vehicle, tyre, bicycle, motorcycle, or equipment may differ significantly from the ranges shown. Always verify against your specific manufacturer specification before inflating any tyre or ball.
2. No Warranty — "As Is"
All information is provided on an "AS IS" and "AS AVAILABLE" basis with no warranties of any kind — express or implied — including but not limited to warranties of accuracy, completeness, merchantability, fitness for a particular purpose, or non-infringement. Tyre pressure recommendations change over time and vary by vehicle model, tyre brand, tyre size, load rating, speed rating, ambient temperature, altitude, and road conditions. We make no representation that any information on this site is current, accurate, or applicable to your specific situation.
3. Not Professional or Safety Advice
This website provides general informational reference only. Nothing on this site constitutes professional automotive advice, tyre safety advice, cycling advice, motorcycle advice, or any other professional advice. If you are unsure about the correct tyre pressure for your vehicle or equipment, consult your vehicle manufacturer, a licensed mechanic, or a qualified tyre professional before proceeding. The cost of professional advice is far less than the cost of an accident.
4. Limitation of Liability
Some jurisdictions do not allow the exclusion or limitation of liability for consequential or incidental damages, so the above limitation may not apply to you in full. In such jurisdictions, our liability is limited to the maximum extent permitted by law.
5. User Responsibility
By using this site you accept full and sole responsibility for how you use the information provided. You acknowledge that inflating tyres incorrectly is dangerous, that you will independently verify all pressure values against your manufacturer's specification before acting on them, and that you use this site entirely at your own risk. You further acknowledge that you have read and understood the safety warnings on this page.
6. Accuracy & Timeliness
We make reasonable efforts to ensure information is accurate at the time of publication, but we make no guarantee that content is current as of the date you access it. Vehicle manufacturer recommendations, sports governing body regulations, and industry standards change regularly. The English language version of this site governs in the event of any conflict with translated versions.
7. Affiliate & Advertising Disclosure
This site participates in the Amazon Services LLC Associates Programme, an affiliate advertising programme designed to provide a means for sites to earn advertising fees by linking to Amazon.

8. Third-Party Links
This site may link to third-party websites for reference purposes. We have no control over and accept no responsibility for the content, accuracy, or practices of any third-party website. Links do not constitute endorsement.

Tyre pressure is a safety-critical specification. An incorrectly inflated tyre can cause loss of vehicle control, serious injury, or death. Always use your vehicle manufacturer's recommended pressure. Always check with a calibrated gauge. When in doubt — ask a professional.
