Tyre Pressure

[ScienceVR6]

is that up or down on your normal pressures?

Up from 32.

Just checked my notes, its 38psi actually!

[ScienceVR6]

i run my fronts at 38, the rears at 36.
At the drags, i ran 20psi in the front and 45psi in the rear

The pressures on the tyre placards are the minimum tyre pressures.

If you are carrying a heavy load add 4 PSi, if you are doing high speed driving then add another 4psi.

Check on the sidewall of your tyes and see what the maximum pressure the tyre can handle. Do not go above this!

I like to run anywhere from 34 to 38 psi. 38 psi makes for a bit of a rough ride, but I know the tyre will not overheat when going fast. I find 36 to 34psi to be the best.

It all comes down to sidewall flex. If the tyre is under-inflated, the sidewall moves around alot, generating heat. This heat is transfered to the air inside the tyre and causes the tyre to wear unevenly and prematurely.

If you inflate to say 36 psi and you are doing highspeed driving for a long distance, up to 120km/h, the sidewall does not flex, therefore stopping the tyre from becoming hot, and succumbing to a tyre blowout, at worse, or uneven wear.

You will be suprised at the difference you feel between 1 0r 2 psi in the wheels.
