Arthur Posted December 1, 2013 Share Posted December 1, 2013 Hi Guys Can someone advise the correct tyre pressures for my new toy. It is fitted with 205x50x15 Avon's. Have looked at various threads and about 18psi seems to be the norm. Is that for normal road use - or track? Have just checked mine and they were all at 30psi ! I thought is was a bit twitchy but I put that down to having driven Land Rovers Discovery's for 20 years. Many thanks for any info. Quote Link to comment Share on other sites More sharing options...
Mark (smokey mow) Posted December 1, 2013 Share Posted December 1, 2013 30 is way to high 18 would be a good place to start from to find what suits your car best. Quote Link to comment Share on other sites More sharing options...
Norman Verona Posted December 1, 2013 Share Posted December 1, 2013 As above. I've run my (Caterham) at 18 psi for 21 years now. ed to add that this may be why it drifts to one side. Quote Link to comment Share on other sites More sharing options...
User0083 Posted December 1, 2013 Share Posted December 1, 2013 30-32 psi seems to be what many people have their tyres at... Then they realise that 16-18 psi is what a seven needs to be. I think most tin tops are around 30psi, so people just put their Westfield to the same. Is a harsh ride and once dropped to 18 the ride improves. This is all road use.

Captain Colonial Posted December 1, 2013 Share Posted December 1, 2013 As above, not surprised it was twitchy! If you liked the handling before, wait until you see how it goes now at 18 psi. Quote Link to comment Share on other sites More sharing options...
KugaWestie Posted December 1, 2013 Share Posted December 1, 2013 18psi all round for me Quote Link to comment Share on other sites More sharing options...
Arthur Posted December 1, 2013 Author Share Posted December 1, 2013 Thanks guys. Have put them down to 18psi. Will give it a try as soon as I can get rid of these pesky Sunday lunch guests ! Quote Link to comment Share on other sites More sharing options...
Norman Verona Posted December 1, 2013 Share Posted December 1, 2013 Just visit the loo and return an hour later. Blame it on the food. Quote Link to comment Share on other sites More sharing options...

John K Posted July 12, 2014 Share Posted July 12, 2014 Argh... Really, really want to check mine right now. But the pump and the pressure gauge are in the boot of the Ford Mundane and the wife has gone to work in it. It's bouncy as eck, so I hope they are set too high. It got new tyres on it on its way from the old owner to me, so I have no idea what they are set at. And the right front is a bit grabby so I was going to check they were the same all round. For the folk saying 18 all round, does anybody run with softer rears and harder fronts? I'm finding most of the bump steer comes from the back. Could this soften that up whilst keeping the front nice and 'pointy'? Cheers Quote Link to comment Share on other sites More sharing options...
pickmaster Andy Lowe Posted July 12, 2014 Share Posted July 12, 2014 I run 18 to 20 all around and the live rear axle at the rear makes it jump around a bit still Bet they are too high after fitting new Westfield drift cars are on 60 psi rears to help them slide not what you need on the road though :( Quote Link to comment Share on other sites More sharing options...
alexander72 Posted July 12, 2014 Share Posted July 12, 2014 14 today for me - 75 seconds later they were at 16 :-) Quote Link to comment Share on other sites More sharing options...
Tricky Posted July 13, 2014 Share Posted July 13, 2014 Bouncy rear might mean your shocks are not adjusted correctly, mine originally came set to the softest which with my lard aboard had a similar effect. Quote Link to comment Share on other sites More sharing options...
John K Posted July 13, 2014 Share Posted July 13, 2014 Unfortunately the tyres were all bob on. Which actually is not a suprise as a Westie owner got the tyres fettled whilst I travelled up to collect it and he would know what they should be set to. I think I will look at the suspension set up. I am not bothered about my own comfort, it is just too stiff for the road. If the rears are only spending 50% of the time touching the road! they aren't giving me value for money LOL Not planning to be a track day warrior so I will look at new softer springs and shocks for next year. Still haven't finished rebuilding the hours and I have to get that done this year... Quote Link to comment Share on other sites More sharing options...
dhutch Posted July 14, 2014 Share Posted July 14, 2014 I tend to run 18 front, 16 rear for the road and autotesting in the dry , sometimes lower for autotesting in the wet or on grass, or higher if I want less grip... 18/16 ish seems to give even wear over the width of the tyre, which rightly or wrongly I think is as good a indication as any along side it feeling ok. *All pressures measured cold.
