OAP Posted July 24, 2006 Share Posted July 24, 2006 I am told that swapping the front wheels for track days, so that the tyres run against the indicated direction of rotation will preserve shoulder life. This sounds good news as the front shoulders disappear first, but has anyone else heard of this suggestion? Link to comment Share on other sites More sharing options...
CharlesElliott Posted July 24, 2006 Share Posted July 24, 2006 Yes, it's recommended by Avon. See here. Charles --- My SuperGraduates 2006 diary My SuperGraduates 2005 diary, My Caterham Academy 2004 build and race diary Link to comment Share on other sites More sharing options...
A10ROX Posted July 24, 2006 Share Posted July 24, 2006 But not if it is wet A10ROX:OK, its an R500 without the magnesium bits sump etc and only 205bhp! Link to comment Share on other sites More sharing options...
CharlesElliott Posted July 24, 2006 Share Posted July 24, 2006 No! And Yokohama A048Rs are cheaper, faster and last longer.

Stuart Faulds Posted July 24, 2006 Share Posted July 24, 2006 It makes very little difference in the wet. Link to comment Share on other sites More sharing options...
shn7 Posted July 24, 2006 Share Posted July 24, 2006 And if the MOT man spots it he'll fail it ☹️. Guess who forgot to swap them back 😬 Steve. Not forgetting Percy the Polar Bear Link to comment Share on other sites More sharing options...
OAP Posted July 25, 2006 Author Share Posted July 25, 2006 Thanks for these replies - I'll change them around next time, which will be next wekend at Goodwood. I'm fed up of ruining tyres, but leaving most of the inside tread on. Link to comment Share on other sites More sharing options...
Casbar Posted July 25, 2006 Share Posted July 25, 2006 Funny, when I spoke to BMTR before I bought my CR500's, I asked the same question, and they told me not to bother, as it makes little difference. Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted July 25, 2006 Support Team Share Posted July 25, 2006 I was told that the main reason for running CR500s the wrong way round at the front was to prevent delamination under hard braking. Yellow SL #32 Link to comment Share on other sites More sharing options...
Stuart Faulds Posted July 26, 2006 Share Posted July 26, 2006 OAP, I can't see the direction of rotation making much difference to the wear characteristics you're talking about. Are you wearing both edges of the tyre while leaving the centre? If so, it would suggest a chronically under-inflated tyre. Link to comment Share on other sites More sharing options...
Jason Plato Posted July 26, 2006 Share Posted July 26, 2006 or too little neg camber and too much roll 🤔 here is C7 TOP South Wales AO Link to comment Share on other sites More sharing options...
OAP Posted July 27, 2006 Author Share Posted July 27, 2006 The outer edges of the front tyres wear out first, and I inflate to 18psi cold on a normal day. Most people seem to use this pressure so I hadn't thought it was too low, besides, there is much less wear on the inside edge. Camber is "standard" ie as the car came from Caterham when new - the only thing I have adjusted is the toe in, and that was to the recommended limits. The car handles without problems, just neutral so I don't want to change, it's just that I was told the edge wear would reduce if ran in the wrong direction. I can't see why this should happen, so I posted on here to see what others thought. I'll try it on Saturday anyway, and see what happens. Link to comment Share on other sites More sharing options...
shn7 Posted July 27, 2006 Share Posted July 27, 2006 Camber is "standard" ie as the car came from Caterham when new Which means it could be set to pretty much anything. It would at least be worth getting it checked. Steve. Not forgetting Percy the Polar Bear Link to comment Share on other sites More sharing options...
