Find the correct tyre pressure for your car. Toyota and BMW tyre pressure charts, where to find your PSI, front and rear pressures, and how to check tyre pressure at a UK petrol station.
Getting your tyre pressure right is one of the simplest and most overlooked things you can do to keep your car safe. Wrong pressure means poor grip, higher fuel costs, uneven tyre wear, and in the worst case, a blowout.
The single most reliable source for your car's correct tyre pressure is your owner's manual. Your car's recommended tyre pressure is also printed on a sticker inside the driver's door frame. Never use the number printed on the side of the tyre itself — that's the maximum pressure the tyre can withstand, not what your car needs.
Pressures sourced from Toyota UK Magazine. Models include Aygo X, Yaris, GR Yaris, Yaris Cross, Corolla, C-HR, RAV4, bZ4X, GR86, Land Cruiser, and Highlander with front and rear PSI and bar values for each tyre size.
Pressures sourced from BMW of Tenafly's official service guide. Models include BMW 1 Series through 7 Series, X1 through X7, i3, and i4. Many BMW models come with staggered tyre setups with wider rear tyres, which is why rear pressure is often higher.
You can inflate your tyres at most supermarket petrol stations including Asda, Tesco, Sainsbury's, and Morrisons. Typically around 50p for 5 minutes.
Visual: A tyre that looks slightly flat or visibly lower on one side. Feel while driving: Heavier or sluggish steering, pulling to one side. Dashboard warning: Most cars built after 2012 have TPMS that displays a warning light.
PSI and bar are two different units for measuring pressure. 1 bar = approximately 14.5 PSI. Always check tyre pressure when cold — meaning you haven't driven for at least an hour.
The most reliable source is your owner's manual in the glove box. Alternatively, check the sticker inside the driver's door frame or inside the fuel filler flap. Never use the number printed on the tyre sidewall -- that is the maximum pressure, not the recommended pressure.
PSI (pounds per square inch) and bar are just two different units for measuring pressure. 1 bar equals approximately 14.5 PSI. Most UK petrol station air machines let you switch between both.
Always check tyre pressure when the tyres are cold -- meaning you haven't driven for at least an hour. Driving heats the air inside the tyre and temporarily raises the pressure reading, giving an inaccurate result.
Most supermarket petrol stations including Asda, Tesco, Sainsbury's, and Morrisons have air machines on their forecourts. They typically cost around 50p for 5 minutes.
