Tyre pressure?

[*AL*]

On my MK1 Vee i have 18" alloys with Toyo T1Rs 225/40/18 i'd like to know the recommended tyre pressure (psi). I have tried the search option but couldn't find anything definate.

This thumb rule seems to make sense.

Manufacturers rarely give a single recommended pressure because they have no idea as to exactly which car their tyre is going to be fitted onto unless it is a homologated tire size for a certain model of car.

The best starting point is the car manufacturer's recommendation and work your way up from there till gains are negated by harsh ride and poorer handling. Never exceed the max recommended pressures printed on the sidewall and never go below the stock settings.

Tim's advice is similar. viewpost.php?p=93436&f=13

Thanks James, at the moment my pressures are 32 psi rear and 30 front,(warm) i'm using 225/40/18s Toyos T1Rs. I might drop the fronts a bit more now and just experiment a bit more.
