I am trying to figure out the correct tire pressure for my UK Spec Mazda 323 tires. I checked the manual and door and it lists the pressure in kg. I am used to psi measurements, so I do not know what it is supposed to be. The door says it should be 75kg. What is that in psi? Am I wrong in assuming most small cars use 30 psi?
Answer:
Always stick to the sticker on the door frame (left or right) or the car manual.
You cannot have tyre pressure written in kg:-) 75 kg means how the tyre should be inflated when there's just on person driving some stuff in the boot.
The pressure is different for fully loaded car, in which case you usually put more air into rear tyres.
I remember inflating tyres on my 1998 Mazda 626 (UK car, 15 inch 195×65) to 2.2 bars. That's exactly 220 pascals. And that's exactly 32 PSI.
Just called my brother with 1999 Mazda 323 (15 inch, 195×55). He's inflating to 2.1 - 2.2 PSI.
So, if you find any numbers in that range, you're in business:-)
The manual should list pressure for different tyre sizes.
And remember, tyre pressure significantly affects handling, braking and fuel consumption. Also, tyre wear (and tyre lifespan in the process) are affected.
Hope that helps.
Answer:
Check the tire itself, it usually tells you on the tire.
Answer:
If you look on the side of the tire it says in really same writing. most tires are around 35psi
Answer:
The type of car is not important. Check on the tires, not the car. The car will not say because different people may put different tires on the car. But your right, it's probably around 32 psi
Answer:
It's recorded on a label in the door frame and can be found in the owners manual. Go by the label and not the tire because handling is affected by the tire pressure.
