JamesA Posted October 19, 2002 Share Posted October 19, 2002 It seems that I have seen reference to a couple of different ACB10 coumpounds. Do ACB10s come in various compounds, I have seen mention of road and soft compounds? If there are more than one compound what are the designations? I purchased some R500 wheels and was looking to put ACB10s on for track days. Link to comment Share on other sites More sharing options...
Fred Posted October 19, 2002 Share Posted October 19, 2002 Generally ACB10's are available in A33 (Hard compound sold by Caterham) through A30 to A24 compound. The definitions from Avon are: A33 Stronger for very hard saloon use A31 Durable compound mostly used on saloon cars A30 Generates higher temperature and grip than A31 A24 Used in medium single seater/soft saloon applications You cannot get ACB10's in A40 as they fail the Load Rating test because they disintegrate! Here's a list of compounds and how to identify them on ACB10's. These figures are current and the Spec is a 4 digit number on the tyre carcass.

V7 SLR Posted October 21, 2002 Share Posted October 21, 2002 I run Caterham compound (A33) SLR sized ACB10s on the road. In general I run them well into the "illegal" territory and get about 6000 miles out of a set of fronts and 4000 miles off a set of rears. In general this also includes an average of 1 trackday. I reckon to remain legal I'd probably only get about 4500 miles front and 3000 miles rear. Doughnuts don't help, but I am unable to stop myself.

SJY910 Posted October 21, 2002 Share Posted October 21, 2002 I wouldn't recommend A33 for track days if you use run them on track days only. I used A33 ACB0's on my superlight last year and they lasted all the year. This year I've run cheap Kumho Ecsta V700's in soft compound. They are far superior compared to the A33's and they're about half the cost. But on the other hand, I'm on my third set but I've also put a lot of laps on the tracks this year (more than 1000 laps...) So if you want to get a fast track tyre, get a soft compund, Unsprung weight etc can't make up for a softer compound. Cheers Peter Peter Simons ---- Modern man embraces the machine.
