correct tyre pressure

psy93 ( snipped-for-privacy@gmail.com) gurgled happily, sounding much like they were saying :

Depends on the car.

Gosh, you got some numbers. Was there any context or key?

36 psi. Yes, it almost certainly would...

it depends on the car they are fitted to, are they aftermarket wheels etc?

from this question no one has a hope of giving you an answer.

on some vehicles it also depends on loading etc..

BLOODY HELL.

Wants to be in the mid 20's PSI. Use 28 PSI as a benchmark.

My fiesta specifies 37 PSI front, 40 back at full load on 165/70R13 tyres.

Is it the Diseasel?

How about at normal load?

Two seconds with Google found this

My son's Escort 1.6i zetec says 36 front, 29 rear, up to 3 persons/normal-load.

I've tried this when driving his car, it's pretty shit. When i put them down to what that website actually coincidentally says, the ride is better, but the tyres don't look too healthy cosmetically, slight bulge so to speak on contact with the ground, but much more comfortable. I'm guessing 36 front is okay afterall, but they're pretty small 195r tyres, so I wonder what's optimal. Thankfully, I can't be arsed checking :)

A lot of modern stuff tends to wear as though it's underinflated with mid to high 20s...

32 front, 30 back, for a normal load, can't go wrong(swap if engine is in rear)

I suppose you could try driving over a sheet of paper and seeing whether the tyre print looks about right, for whatever value of alright you choose natch.

Hm, interesting. I noticed on the given website in this thread they say that tyres may look the same, perhaps have the same tread pattern, even if one has 33% less PSI compared with a tyre with the correct pressure!

The Escort has 195/50 r15 wheels, 36 29 says the manual up to 3 persons, i've put it to 35, 31, and it's now a much better ride.

Goodyear poster on the local BP garage says 33, 26 - but that sounds like bollocks.

Have you asked Ford? They do change pressure specifications.

Also, there's absolutely no compromise to trying all pressures too.

By way of an example, my Ka's handbook said something like 31 / 26. Like the Escort, the recommendation for high load was a significantly higher rear tyre pressure. At standard pressure, one or two up the Ka wore his rear booties as thought they were under inflated. 32 / 30 on the standard

165/60/14s worked well. After changing wheels, 34 / 32 reduced sidewall flop and reduced oversteer... under most conditions.

26 all round I think.

Nope.
