gogsboy 0 Posted December 12, 2006 Hope this is the correct place but wonder if someone could advise on what pressures my tyres should be at ideally. It's a Corrado VR6 but has 17" wheels with 205/40's on them. Any ideas, previous owner seems to have had them at 37 front and 30 rear. Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted December 12, 2006 i have my standards at 36 front, 32.5 rear Quote Share this post Link to post Share on other sites
vwdeviant 0 Posted December 12, 2006 :shock: They sound way too high! There should be a sticker in passenger side door shut saying what the pressures should be, however IIRC, 30 fr and 28 rear sounds about right. Too high and you'll just wear the tyres out quicker,, Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted December 12, 2006 i read the manual and the stickers and thats what i saw, i'll double check tonight tho Quote Share this post Link to post Share on other sites
Guest Posted December 12, 2006 i read the manual and the stickers and thats what i saw, i'll double check tonight tho just checked mine on the (DRIVERS) door :lol: 36 on the front, and 32 on the rears (with a half load) Quote Share this post Link to post Share on other sites
vwdeviant 0 Posted December 12, 2006 Wow that seems really high! Even my 2-tonne Saab recommended 32/30! Will have to go and sort those at the weekend! Dave how's the wheel refurb coming? Are you still on your Speedline rollerskates ;) Quote Share this post Link to post Share on other sites
Guest Posted December 12, 2006 Speedline shopping trolley wheels for the foreseeable future, BigChris is A.W.O.L. in Germany at the moment :( Quote Share this post Link to post Share on other sites
NickVR6 0 Posted December 12, 2006 I run 30 front and 29 back with 205/40/17s on 8x17s. Mainly because im a bit of an old man when it comes to ride comfort. id take them up maybe 2psi for the track but then they got hot and increase anyway. But for the road 30/29 works for me :-) Quote Share this post Link to post Share on other sites
Bojmobile 0 Posted December 12, 2006 I run with 36psi front and 32 rear - although I think I've left my digital tyre pressure gauge in the road last time I did mine as went to check them at the weekend and can't find it! :cry: Quote Share this post Link to post Share on other sites
gogsboy 0 Posted December 12, 2006 :shock: They sound way too high! The standards sound way to high or both in your opinion? Quote Share this post Link to post Share on other sites

But for the road 30/29 works for me :-) Surely if standards are meant to be 36/32 or thereabout, 205's on 17's should be the same or slightly more.......or is that not the way to look at it. Also when you say 30/29 works for you what sort of gauge is that checked on? Quote Share this post Link to post Share on other sites
herisites 0 Posted December 12, 2006 Will the tyre pressures need to change for stretched tyres at all? I am running 9's with 215/40's so what would be the best tyre pressure for me for some sort of comfort but without lazy steering? Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted December 13, 2006 i've always thought tyres pressures should be the same no matter what the tyre size, as it the same car, same weight being put on tyres, it may be less air but at the same pressure. i'm not 100% on that, but is what i believe to be true Quote Share this post Link to post Share on other sites
herisites 0 Posted December 13, 2006 Well i have just put normal pressures in as i thought the same thing as you, but just thought id ask in case :lol: Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted December 15, 2006 i've always thought tyres pressures should be the same no matter what the tyre size, as it the same car, same weight being put on tyres, it may be less air but at the same pressure. Nope. 17s have much stiffer sidewalls and a larger contact patch, so don't need as much pressure as smaller tyres. Tyres should be inflated to the optimum pressure that doesn't cause wear in the middle or outside edges, not the pressure that's on the door sticker, which is the pressure based on the factory fit tyres anyway. As soon as you change the tyres for a different brand, all that goes out the window, even standard size. Let the tyre tell you what pressure it should be at. You can just feel (and see) when they're at the optimum pressure and it's usually always 32psi front and 30 rear on VWs. Manufacturers that quote unusually high pressures are just trying to improve the mpg figures for sales reasons. Quote Share this post Link to post Share on other sites
gogsboy 0 Posted December 15, 2006 So guess my fronts need let down a bit since they are at 37, which is what previous owner had them at. Problem with the garage gauges they always seem to read about 3-4 PSI according to the gauge I use (ITC one) Quote Share this post Link to post Share on other sites

Yup go with that I've just stuck "factory" pressure in the tyres on my valver and now booking myself into the dentist to get my fillings put back! The door quoted 38/33 half (ouch bang crash POTHOLE!) and something ludicrous like 41 for full! Going back to 33/30 as soon as I can! Quote Share this post Link to post Share on other sites
