PugAddict 0 Posted January 20, 2008 Hey folks Currently running 1.9 GTi SMR's on my 306 Sedan '94. The engine is the 1.9 turbo diesel lump, and the whole car weighs approx 1140kg which is a little more than a 205 I'm sure you'd agree What PSI should I be pumping the tyres to when cold? Currently using about 33 psi on 185/55/15's Tried a quick search but nothing concrete Thanks in advance Share this post Link to post Share on other sites
jord294 92 Posted January 21, 2008 i'd go with 32psi Share this post Link to post Share on other sites
PugAddict 0 Posted January 21, 2008 What psi do the GTi's run? (normally on 195/50/15's I expect) Share this post Link to post Share on other sites
engine killer 6 Posted January 22, 2008 anything over 30psi seems too skiddy for me. i normally stick with 28psi. Share this post Link to post Share on other sites
Normski 1 Posted January 22, 2008 What psi do the GTi's run? (normally on 195/50/15's I expect) They run 2.0 bar front and rear (29psi) on the std 185/55-15. I'd go along with 31-32psi for your case. Share this post Link to post Share on other sites
welshpug 1,657 Posted January 22, 2008 GTi6 runs 36 all round IIRC. but that's on 195 55 15. Share this post Link to post Share on other sites
PugAddict 0 Posted January 25, 2008 Looks like I may as well stick to 33psi then Cheers for the replies Share this post Link to post Share on other sites
peter 20 Posted February 7, 2008 Would 45 profile make any difference? Share this post Link to post Share on other sites
welshpug 1,657 Posted February 7, 2008 nope, as the weight of the car hasn't changed, though slight adjustments may make the ride/handling better/worse. I guess you mean 195-45/16"? Share this post Link to post Share on other sites

The weight of the car may not have changed but reducing the profile reduces the area of tyre the pressure is acting on. So reduces the weight it can hold up, meaning pressure would need to be increased. (Only slightly, it's not going to be a massive difference). Share this post Link to post Share on other sites
