ian balson Posted March 19, 2001 Share Posted March 19, 2001 Hi All, I'm currently running the SLR wheels with CR500 tyres. As the rears are 8.5" wide, can I run any other tyres apart from the CR500's or ACB10's ? Thanks Ian. Link to comment Share on other sites More sharing options...
murph7355 Posted March 19, 2001 Share Posted March 19, 2001 The only other usual suspects are Yoko 021Rs (possibly the best compromise road tyre available for the 7 with superb wet weather ability, very good dry ability and good wear rate) or 032Rs (alleged to be not as good in the wet by some - I've yet to try them - better in the dry but not as good wear wise). Both of these are availble in 205/13 or wider (but I'd be inclined not to go any wider). C7 AJM Link to comment Share on other sites More sharing options...
John Richens Posted March 19, 2001 Share Posted March 19, 2001 Ian, what are you looking to do...run slicks for a track day ?You've chosen the best road tyres for wet and dry so far.. Link to comment Share on other sites More sharing options...
ian balson Posted March 19, 2001 Author Share Posted March 19, 2001 John, Just wondered what the options were, and if there were any cheaper alternatives given the width of the rear wheels. Is it okay to run A032Rs @ 205 width on 8.5" rims ? What's an average price for an A032R? Ian Link to comment Share on other sites More sharing options...
John Richens Posted March 19, 2001 Share Posted March 19, 2001 I've no experience of running 032's ,but they were on my list before I upgraded my Seven...George Polley in Heathfield East Sussex is The man for YOKO's. The CR500 is an excellent allround tyre with very good wet weather grip, ACB 10's are better in the dry ,you can get them in varied compounds,but have a tendancy to tramline on road surfaces.

murph7355 Posted March 19, 2001 Share Posted March 19, 2001 Hmmmm. Yoko seem to have 6" or 6.5" as the "permitted" rim widths for 205s... I wonder what impact putting them on wider rims will have to insurers (mine are on 7"s). This rim width seems narrow to me (ed. after : Avons equiv. CR500 has a recommended width of 8"!), and would indicate that you'd need something like 245s on an 8.5" rim. I'd say that this is way too big for the back of a Caterham, if you could buy tyres that wide for 13" rims (8.5" ACBs are only about 215s ed. after : according to Avon's site this is wrong! 8" ACB10s are equivalent to 245s...). None of which helps you very much! 205 32Rs are iro 60-70 a corner, or about 2/3s the price of the CR500s. 21Rs are about 10 quid cheaper I think. For something that runs out so quickly (3k-7k miles) I'm prepared to compromise a bit on outright grip (it'd be interesting to see comparative times round a lap of a circuit) to save a fortune in new tyres!

Merrick Linnett Posted March 19, 2001 Share Posted March 19, 2001 Ian, Check with George Polley he had 032R's in the 215 size, hard compound only at the moment. Merrick. Link to comment Share on other sites More sharing options...
