So much Torque...

[Umai Naa!!]

Good advice on keeping the pressures high.

It's pretty muchg the only way to keep tyres on the things.

40PSI will reduce the contact patch, and increase wear through the middle of the tread face. Sure, it will help the edges wear better, but you won't be doing your traction any favours.

Load inflation tables are your friend. The whole tyre manufacturing industry uses the same references, so it doesn't matter which table you use - but recommended pressures exist for a reason.

Here's an example table:

My Alltrack runs 245/40-19. Tare weight is 1671kg, and for the sake of simplicity lets say its evenly distributed across both axles. That equates to 3676lbs (only did that conversion because I am using an american load inflation table).

At 40PSI the tyre carcass is rated to 1600lbs PER TYRE!


To each their own - and if you want to run high pressures then so be it - but getting some extra kays out of your tyres by increasing the pressure is not necessarily a brilliant thing to do. You've substantially reduced the contact patch which dramatically reduces the traction profile of the tyre.

You don't know exactly how it effects the tyre in terms of wear, until you try it out.

If you run what the tyre placard suggests, you'll trash the edges of the tyres in no time.

You wouldn't run 40psi in the tyres of a base model Polo, but a heavy-ish car like a Passat Alltrack, you'd certainly consider it.

Um, I HAVE a Passat Alltrack, and they have quite a lot of rubber under them. I find 32PSI plenty, and the shoulders of the tyres are just fine.

Hey Anthony,I agree. I have always ran 32 to 36 max,but these tyre guys always say go the 40.
Does it make them wear quicker?? Only time and mileage will tell. I was amazed the original front
wore within the 15k,I had 36 in them and when I got the wheels aligned they said within spec.
What do you do? Trying Pirrellis now and the original back ones still in top condition.I live in suburbia
wher roundabouts rule along with stop and give way signs.Its a jungle.Its like the directions on the washing
powder pack:Use 1 full scoop but the washing machine manu man says,quarter that.Its better and they want
you to buy more powder or tyres..LOL

I run 40 psi in my R36 to shut the tyre pressure warning system up and my toyos wear evenly and slowly, even though their wet performance is pretty terrible, I'll be looking at Michelin Sport 4s when the car needs new boots as they seem to be the recommended price/performance/wear compromise for the R36.

i got 235/35/19 on my golf alltrack and i run 36psi tyres are ventis v12 at 13k now tyres barley worn and i do give em a hard time

Tyres are a big talking item......well they are very important and you can only ask for
opinions and then do what you think is right that also suits your ride.

Well said. There is no right or wrong answer.

On my B7 which has done 36000 the tyres still have nearly 4mm on them with mainly highway driving.Usually run at 40lb

Courier and babying a car Thats an Oxymoron isnt it LOL
