My T30 runs at 45-50psi :thumbs: tends to make for a hard ride but avoids scrubbing the edges out and keeps fuel consumption at good levels :thumbs:

Use to run all my vehicles around 30-34psi and was surprised the difference it made whacking it up, improved tyre wear, improved average MPG by about 5-8mpg

Does make them a little more skatey in the wet mind and snow/mud they are rubbish but then you let them down for those times.

 

The recommended tyre pressures should be on the plate on the driver side B Pillar.

Mine shows 33 psi (2.3 bar) for the front & 30 psi (2.1 Bar) for the rear.

Same with mine, although I tend to increase the values by about 2 psi, it seems? better that way.

 

33psi all round on 18", all wear even across the tread,

 

Thanks people. For some reason mine doesn't have the plate. I knew it should be there but its not.

 

I had all tyres replaced recently and noticed on the worksheet that they set all the pressures at 40psi.

Steering is a lot lighter lol.

45-50 and it gets lovely and light :thumbs: saves tyre wear, saves fuel, saves wear on all the steering joints, whats not to like :thumbs: oh it doesnt stop as well in the wet :lol: hey ho you cant have everything

Rough uncomfortable ride, increased wear on suspension components and when you run in the back of someone (or worse) and PC plod checks your car over you get done for driving a vehicle outside of the manufacturers spec. But hey ho, you can't have everything :roll:

All the tyres will have burst anyway :lol: :lol: :lol: if not I'd quickly let them down :lol: :lol:

Might put a little note on the wheel arch's saying "in case of crash please let tyres down by 20psi :thumbs: :lol:

Then again I drive most of my vehicles............. "outside the manufactures spec" :mrgreen:

 

Sorry to dig up an old thread but I was talking about this yesterday.

I noticed that my tyres say (max 50psi). They looked flat and found they were at 30psi.
I pumped them up to 46 and the steering is so much better.
My old man said that I will loose some control in the wet, but I'll just let some air out for the winter.

I'm wondering if that's tongue in cheek or not. . .

If you reduce the surface contact patch of a tire, by over inflating it and changing the flat surface into a curve, we'll then of course the steering will be light, mpg better and Wear on edges less, God help your road holding, braking and ability to control it. . . 33 on 16" is what worked for me.

As previously mentioned the correct pressure is on the door jam - this takes the vehicle weight etc into account. Tyres are used on lot of different vehicles.

Also, don't forget over inflating means the centre of the tyr wears quicker so you gain nothing. Add to that, pressure can increase by 5-8 psi on a hot day.

Each to their own.

Lewiswalks,? he will when he puts it in a ditch,

 

At 30psi, they seemed very low.
I have done a few emergency stops in the wet from 30, 45 and 60 and I don't seem to have lost any stopping distance or control.

I'm not against taking advice. If you guys think that 45psi is way to high, then I'll drop them down to 35.

I have also taken tread depth recordings across each of the 4 treads on each tyre so I can see if they are wearing unevenly.

 

I've experimented with pressures (on road use) with my full mud tyres and all terrains, what I found was the safest and most predictable tyre pressures were the ones the handbook for the car said to use. Each to their own choices, but thats what I found after testing.

 

I worked for Goodyear for 14 years, and the tyre pressures can very slightly between manufactures. The door jam guide is based on the tyres fitted from the factory. Upping the pressures by 2 to 4PSI is fine, and is normally recommended if carrying more load or driving at high speed, and would not impede stopping distance by noticeable amount. Any more and it will and also cornering grip. I have always on all my cars, run 2 to 4 PSI higher. The recommended pressure is a quit often a compromise, between grip and driving comfort. So a few more pounds will give rougher ride but not lower the grip by a noticeable amount. Thinks that will low grip, especially in stopping is the shock absorbers. Just one weak shock will will increase the stopping distance from 30MPH by 8 feet. That's the width of a zebra crossing.
