Aftermarket alloy wheel tyre pressures

[gilly_15]

Hello

this is a post for a freind of mine, he has an 06 seat leon, and it came with aftermarket 18" alloys, but he doesnt know the correct tyre pressure for these and i am not sure myself.

The tyre sizes are - 225/40/18

does anyone know what is the best/correct tyre pressure for this size tyre?

thanks

Tyre pressure is related to their load so they should be the same whatever size/make wheel you have
