Miles Taylor Posted February 6, 2004 Share Posted February 6, 2004 Just ordered new R400. Having had Yoko AO32R s on my old 1400 ss which were brilliant on trackdays ( 5 per year ) but not experienced use in wet would anyone have advice on whether to have these from new or are the Avon CR500 standard spec tyres a better option? I'm intending to do a bit more road driving now also. Milo Link to comment Share on other sites More sharing options...
jwyatt Posted February 6, 2004 Share Posted February 6, 2004 I've used both, wet and dry (though on a lot less bhp!) and would say go for the CR500's for feel, controlability, and wet grip advantages. 32's grip well but don't drift that well, and in the wet they can be dodgy in standing water!

rgrigsby Posted February 6, 2004 Share Posted February 6, 2004 CR500's are great road tyres but they are not a good choice for dry track days, I've driven lots of miles in the wet and dry on both 032r's and CR500's. Ultimately in the dry the 32R's are great but as an allround road tyre the CR500's are probably better The other option is Yoko 048r's, they are a new tyre that is a compromise between the 32r's and the CR500's apparently.

glyn_b Posted February 6, 2004 Share Posted February 6, 2004 Personally I would not underestimate the benefit of sticking with what you know and are used to from your trackdays. Yoko's are also much better value IMO Link to comment Share on other sites More sharing options...
noddy Posted February 6, 2004 Share Posted February 6, 2004 I have driven approx 1800 miles including 4 track days in 3 months (mainly wet/damp/cold) so far on CR500's and have found them to be excellent. I too am thinking of alternatives though, mainly from a cost/wear point of view. It will be interesting to hear everyones views ❗ R400 .......... I love it Link to comment Share on other sites More sharing options...
Sheds Moderator Posted February 6, 2004 Share Posted February 6, 2004 Oh God, here we go again....tyres, tyres, tyres. 😬 My opinion, in summary: Yoko 032s great in dry, wear too fast. Slippery if cold and damp. Bridgestone RE720 harder wearing, less grippy, good in the wet. Both nice and cheap at under 40 quid 185/60/13. You choose.

rgrigsby Posted February 6, 2004 Share Posted February 6, 2004 I'd tend to agree, the 032r's are a great tyre in most circumstances, it's just they can be a bit lively in the wet. The CR500's don't have anywhere near as much grip in the dry but are much much grippier than something like the Bridgestones and in the wet they are very very friendly. But they do cost quite a bit more. Having said that past experience from several people seems to suggest they will last much longer, possibly as much as 9000+ miles depending on use. Ultimately the best solution is probably CR500's for wet/track days and slicks/32r's for dry ones but for that you need a second set of wheels (not to expensive 2nd hand) and a wheel rack for the FIA bar!!

darren f Posted February 6, 2004 Share Posted February 6, 2004 Miles, I have run both CR500s and 032Rs on R300SEV in the last year. Expanding on Rob's last comment, I think you need to think about where you will get most use. If its 'all conditions road work' then go for the CR500s which I have found first class in the wet. If its 'dry road use' or track use then go for 032Rs, which whilst even better in the dry, are seriously compromised in standing water situations. On a track you can normally judge where the puddles are, on the road you cannot . darren f The Building of R300SEV is Here Link to comment Share on other sites More sharing options...
Myles Posted February 6, 2004 Share Posted February 6, 2004 CR500's are great road tyres but they are not a good choice for dry track days Eh? Why? Cost compared to 32's??? I only ask because I started off the car ownership on 500s on the road, but 'relegated' this set of wheels for track days (in favour of RE720s - which I am seriously impressed with given the cost and longevity). The two reasons for doing this were to cut down on road-usage costs (I found myself doing many, long journeys where 500s were just being wasted) and to save the grip up for when I really needed it... ...possibly as much as 9000+ miles depending on use. FWIW, my rear 500s lasted almost exactly 5000 miles (on a 1.6 115BHP k-series) and I reckon the fronts have got enough left to do either a) one track day or b) the road miles to and from a trackday, but not both... I seriously doubt 9k... and as I mentioned above, quite a lot of this mileage was wasteful road miles (i.e. m-ways and other boring straight bits)... YMMV though.... Keep BC free and open for ALL.

dino ferrana Posted February 6, 2004 Share Posted February 6, 2004 If you have the standard wheels on the R400 then these are 15's and the 15" CR500 is a little bit harder compound I believe. I think there is a 15" AO32R but I am not totally sure, on things for sure it will be quite a lot heavier than the 15" CR500. Link to comment Share on other sites More sharing options...
jwyatt Posted February 6, 2004 Share Posted February 6, 2004 Having used the 032R 185/13 in SS and the CR500 in 175/13 on the same car in races at the same tracks in the same year/conditions, I disagree strongly with the sentiment that the 32's are much faster as suggested above. My times were similar, even favouring the CR500's. Then agin that was a Roadsports B/750MC class C car with only 120bhp. But in my experience (not disputing other's) they are not dissimilar! The feeling of contralibility of the CR500 is vastly superior, probably due to light weight Edited by - jwyatt on 6 Feb 2004 14:04:18 Link to comment Share on other sites More sharing options...
GTD Posted February 6, 2004 Share Posted February 6, 2004 Yep - agree with James on that (we raced 750 MC race on the Yokos, RS-B or Supergrads on the CR500's). I liked the 32's for their cost. They feel more 'stuck' to the track to me when it's very hot,dry - which is a confidence booster and probably made me slightly quicker on them in those conditions - but if it cools down they are the same, and if it's damp I'd go CR500's.

mr_ed Posted February 6, 2004 Share Posted February 6, 2004 What is the exact size of the "front" CR500s? Are they 175/60/13 or 175/50/13 (similar to ACB10s) ? Anyone got a weight for one of these? (a 185/50/13 ACB10 is 5kgs, a 185/60/13 A032r is 7.2kgs) Cheers, Ed Link to comment Share on other sites More sharing options...
