SLR69 Posted November 17, 2007 Share Posted November 17, 2007 I am about to fit a a pair of new CR500 on the rear and then do a trackday immediately after. I gather new tyres have a compound on the outside of the tyres that has to wear off over a few hundred miles before the tyres are at their best. Anyone know how many miles you have to do to wear this compound off as I am only going to have time to do about 30 miles prior to the trackday and I am just wondering if the tyres will therefore lack grip. Or would a couple of standing starts have the same effect of burning off the compound ? Link to comment Share on other sites More sharing options...
MikeW Posted November 17, 2007 Share Posted November 17, 2007 I use new tyres all the time on track-it only takes a couple of laps to get rid of the release agent so I wouldn't worry. Try not to overheat new tyres too quickly though-it's a lot better to progressively load them up IMO MikeW Mega Grad Race No 8 Link to comment Share on other sites More sharing options...
SLR69 Posted November 17, 2007 Author Share Posted November 17, 2007 Mike, Thanks for the reply. Release agent.....................now that's the terminology that I couldn't remember. Regards Stuart Link to comment Share on other sites More sharing options...
dudlow Posted November 17, 2007 Share Posted November 17, 2007 SLR69 I need new cr500's all round. I have never bought any before, can you recommend a good source ? I imagine that living in Guernsey you did not buy locally. Link to comment Share on other sites More sharing options...
mav Posted November 17, 2007 Share Posted November 17, 2007 you are only likely to get them from CC, BMTR or Avon direct at the keenest prices. Link to comment Share on other sites More sharing options...
FTH Posted November 17, 2007 Share Posted November 17, 2007 AKA "scrubbing a tyre in" only realy an issue on bike tyres. Link to comment Share on other sites More sharing options...
SLR69 Posted November 17, 2007 Author Share Posted November 17, 2007 Dudlow, I got mine from CC. FTH, it's not just bike tyres but slicks as well. I remember doing a hillclimb two years ago and forgot on my first run that I hadn't scrubbed the tyres in and they let go on the very last bend and fastest bend of the hill and I spun out of control over the line backwards and up a bank - and that was in a Subaru Impreza with 4wd - all because the tyres were new and not scrubbed in - and in the process I also broke my PB on the hill !

Stationary M25 Traveller Posted November 17, 2007 Share Posted November 17, 2007 CC were the cheapest when I bought a pair. The CC price inc VAT was the same as the BMTR price without VAT I recall. Dudlow - Paul Stapley will fit tyres to rims (and balance) at your home if you want. If you can't get to CC Dartford to collect tyres, let me know, as I can usually get there Sat am (or maybe even one day during the week if necessary). 7 related photos Edited by - Stationary M25 Traveller on 17 Nov 2007 23:46:14 Link to comment Share on other sites More sharing options...
