I know this has been done to death but, I'm after a definitive answer, which i know is difficult on a public forum!!!

Just taken delivery of Ibiza Cupra wheels (mk4) on 205/40/17's. What pressures should these be running??

30psi Front and 28 Rear seems to have gained popularity on the search, I think the recommended 33psi + etc is a bit high.

Any thoughts?

The closest you will find to a definitive answer is what it says inside the fuel filler cap :) If you want conjecture and opinion, read the inevitible replies.

30 psi front and 28 rear for max grip. Higher for longer life and increased MPG.

Are you talking Cupra diesel or petrol?? The heavy diesel should mean different pressures to the petrol.

205/40/17's are standard aren't they on the Cupra?? So, just go with what it says in the fuel cap.

Your best bet is not to follow what SEAT say at all. Instead go on the tyre manufacturers site, put in your vehichle details and see what they say. For my GSD3's on a ibiza they said 30 front 28 rear.

I run about 34 psi all round as I do lots of motorway miles and don't need lots of grip for corners! Seems OK. Not much difference if your only talking a couple of psi though (32 compared to 34, 34 compared to 36 etc.)

a friend was talking about filling with nitrogen, does this make any difference and worth the cost?

Not worth it for road cars. I know some hyper cars come with it stock, including the new GTR iirc.

I can't say there is a definitive answer as it will depend on how you like your car to feel/the tyres (different brands, models, sizes). Personally I run 2.2bar all round and I like that, but I tend to have a boot full of crap. (Yep they are the pressures I ran at the pod)
