Tyre Pressures on Option Wheels

[leon1p]

I have the 18" BBS wheels (225/40/18) that you get as an option on my 06 2.0 TDI Leon.. Where can I find the correct tyre pressures for this combination (i dont have my handbook at hand to see if it lists this but I doubt it will)

All four tyres are different at the moment.. 26, 28, 29, 32.. so I have no benchmark to know where to start. The dunlop site only gives pressures for the 16" rims.

Bolt Torque 110nm
Rim Size (front) 6.5 x 16
Rim Size (rear) 6.5 x 16
Normal Load (front) 2.2bar (32psi?)
Normal Load (rear) 2.1bar (31psi?)

Can anyone suggest whether I should match these pressure or whether larger wheels require more/less pressure. Im really at a loss just now and don't want to comprimise the condition of the tyres. 95% of the time the car is unladen although this weekend I will have 3 passengers.

Tyre pressures are calculated by the manufacturer on axle weight.
Basically you keep the same pressures no matter what size wheels you fit, apart from specific winter wheels and tyres which often require different pressures and will be in the user manual.

Haha it's really as simple as that? Thanks mate I'll set them per the label in the fuel flap and see how it feels.
