Tyre Pressure

**MattW** · 21st May 2009, 00:21

Just looking on the Vredestein website, and it says for the tyres I have for the Vectra I should be running the below PSI

Ultrac Sessanta 225/45 ZR 17 94 Y XL 42 PSI 45 PSI
Does that seem a little high?

Yeah, I'm running 34 front and back at the minute, just thought I'd double check as the pressure they list on their site seems really high.

no way 40 odd, thats way to high if you ask me and if you hit a pot hole too hard you will blow the tyre as to much presure and the wall wont flex like its meant to

As some of the other posts in this thread, I am also running 32 psi all round, as specified in the handbook.

rule of thumb for tyre pressures is......
double the rim size and add 2lb..

16 x 2 = 32 + 2 = 34
17 x 2 = 34 + 2 = 36
18 x 2 = 36 + 2 = 38
19 x 2 = 38 + 2 = 40
etc etc etc....

i have 18's and they are 38lb all around....
