Tyre pressure?

Stheno

Anyone know where to find the recommended tyre pressure for 245/35zr/18/92ylp tyre size?

Or is it car dependant?

frozenfrozen

depends, go by what's on the door jam sticker and have a look online and see if the tyre manufacturer has something listed for those tyres on your specific car

When in doubt that rule works well. for cars anyway, untill you can find the correct psi.

OP, it depends on the car. What car is it?

Recommended tyre pressures specifically for your car will be listed in the owner's manual.

It has the correct pressure for my car, which is 35, so it's most likely correct for the BMW. LGV and HGV go much higher

Go by what's on the door, maybe double check forums for that model car to see different results.

My mam's diesel i30 says 32psi even though that's the same pressure as the lighter petrol model. A quick check of the i30 Owners Club forums shows most diesel owners running 38-40psi and getting better fuel economy and better handling.

Obviously the engineers in Hyundai got it wrong and the forum members got it right

Of course, they've only driven them tens of thousands of kilometres and have real world improvements. Just ignore the weight difference, what do these guys know. I guess I'll ignore the advice on the cycling forum about being a heavy rider also needing higher psi because a forum post doesn't mean much.

What about the fact additional passengers needs an increase in psi? If the weight difference between petrol and diesel doesn't matter why does a passenger matter?

It is car dependent, as axle weight greatly affects it.

F.e. on two different cars, on 215/65/R16 tyres I've seen recommended 1.8 bar and 2.0 bar.
With 205/55/R16 I've seen cars needing as low as 2.0 bar and as high as 2.8 bar.

Thanks. I'd been using 32 and it says 33. Good to know.
