Hi all, Just wondering what the best tyre pressures would be for a 1.0L Corsa 2001 3dr model with michelin energy tyres (radial XSE - 175/65R14 82T-XT1). Vauxhall, my local dealer, company I service with, the handbook and various websites have a lot of very different figures. Just had car serviced and front put up to 34 and back 31. I normally run with 31 front and 27 back. Handbook for not exactly the same tyre but close says 30 front 23 back and vauxhall was something completely different. Can anyone shed any light on what figures would be best?! Thanks! L
