What is the correct tyre pressure for my A2 Tdi 90 with 195/45/16 tyres

The details on the fuel flap don't tell me what the correct pressure should be.
I have set them at 32 front 30 back.
Can you help please?
 
There is no absolute 'correct' pressure although you are of course right in the ballpark.

The best pressure depends not only on your load, but the type of driving you are doing. In short, high speed motorway driving requires higher pressure than low speed around town pottering. To get the maximum grip from those 195s, as well as a more comfortable ride, you'd probably want to drop those pressures a fraction for day-to-day use.
 
Does 30 front and 28 rear sound right. I'm in the car on my own most of the time.

Cheers,

Near enough. My petrol A2 has an aluminium block so doesn't have the weight penalty up front of yours, and I use 29 front and rear as my maximum pressure.
 
I've been using 34/32 front/rear on all three of my TDI 75's to cover all situations, albeit mainly involving 20-mile runs cross-country at or below speed limit and not too hard on the corners. Should I revise those downward a touch do you think?

What size tyres are you using?
 
185/65x15 Cross Climates, 195/50x16 standard tyres, 215/40x17 Dunlop Sports. Also have a set of 185/55x16 standard tyres.

Well that's quite a variety. In general, the higher the profile, and the larger the cross-section of the tyre, the lower the necessary pressure. And winter driving, where grip is paramount, should run lower pressures than summer. F1 cars barely inch into the 20s with their tyre pressures.

I doubt I'd be comfortable on your pressures, although of course they're going to offer optimum fuel economy for the sizes in question. So long as your tyres are wearing evenly across the tread, you can't go too far wrong.
