anyone got a decent guide to tyre pressures?

pump too much in and your car will lose lots of grip. not safe to do this mate. i run 32 on my mk3 on 17's and was running 30 on 15's.

^ a mk3 8v again?


i was asking for official figures... i've seen 38 (petrol flap) and 41 (haynes) for my car so far..

one of my front tyres had gone down to 30 PSI and it looked flat..

8v flap ...

ok so according to that (which i think is not quite the same as the one in my car)

195s all around part loaded = 36 front, 33 rear
195s all around fully loaded = 38 front, 41 rear 

205s all around part loaded = 30 front, 28 rear
195s all around fully loaded = 33 front, 36 rear

if we use that for my motor...

part loaded.  36 front, 28 rear
fully loaded. 38 front, 36 rear

this also proves adding more weight means a higher PSI should be used..
therefore the heavier 16v may mean the pressures need to be a bit more all round


i'll take a shot of mine when i'm home for comparison

My petrol flap gives one set of figures, as presumably VR6's only had 205/50/15 tyres as standard.  Which is what mine has.

Pressures are:
Unloaded - Front 38 Rear 35
Loaded - Front 41 Rear 44


Don't underinflate the tyres as handling, braking and fuel economy will all suffer.  If you are running standard wheels/tyres go with what VW put on the car.

Also, the edges of the tyre will wear much quicker with underinflated tyres, as i found out when running 215/40/16s at 30psi.

Overseer, i would use the pressure's you arrived at in the last post, then as soon as one pair of tyres wears out decide if you want 195 or 205 and keep them all the same.  Although i'm sure that's your plan anyway.  If it helps, my p reg 16v had 205 all round so i would expect that's what yours should have.  Only trouble is, 195s are much cheaper than 205s!

yeah i been wondering what to do.. whether to even out and have 1 size all round... although it does look kinda phat with different sizes front->back since it makes it look meaner..

thing is.. i've only been replacing the ones that need doing..

and i hope to grab a set of anniversary wheels at some point.. so it wont be an issue then.

i'm running 38/38 right now and it seems fine..

didnt remember about taking this pic until i'd jumped out the shower after getting home earlier.. n couldnt be bothered to dress again to go outside n take pics!
