AdamP 0 Posted June 25, 2008 I'm running 6/21 R13 Avon ACB10s on 13x5 rallye steels. Car weighs around 700kgs (completely stripped out roland garros, polycarb windows, no sunroof etc), and I have absolutely no clue as to what pressures I should be running. I've been told around 26psi, and also around 16psi. Had them at 26 on the weekend and they did seem a little 'over inflated'. Any ideas? Adam Share this post Link to post Share on other sites
swordfish210 20 Posted June 25, 2008 well they have pretty hard sidewalls so you can get away with a much lower pressure. I know it's not the same but we used to run 14F and 16R on the Formula Fords. I would try 22F and 20R, see how that feels. Share this post Link to post Share on other sites
AdamP 0 Posted June 25, 2008 I thought around 20 would be sensible. Will give it a try on the weekend (prescott hillclimb!). Share this post Link to post Share on other sites
James_R 3 Posted June 25, 2008 I ran 26Psi in them cold on my 205 stripped caged still with glass, 8v in it. 1 Share this post Link to post Share on other sites
