Captainbilos Posted January 15, 2001 Share Posted January 15, 2001 I'm thinking of getting some new tyres. Caterham suggest that I try the R500 tyres (Avons), does anyone have an opinion of these compared to either 032R's or 021R's. Link to comment Share on other sites More sharing options...
murph7355 Posted January 15, 2001 Share Posted January 15, 2001 Nearly twice the price (as the A021Rs. At least 50% dearer than the 32Rs). Never tried them but doubt I will. Feedback I've heard from others is that they are tremendous in the wet, but not as good (certainly as ACB10s) in the dry... I've got A021Rs and these are pretty good. And I'm hearing more and more that 32Rs aren't as bad in the wet as you hear. I'll be trying these next time. Have search for 'cr500' and you'll get much more feedback...

Petrolhead Posted January 15, 2001 Share Posted January 15, 2001 Any feeback available from people using 21Rs and 32Rs. Which seem to the best all round performance, cost etc? Link to comment Share on other sites More sharing options...
Pierre Gillet Posted January 15, 2001 Share Posted January 15, 2001 From my perspective, for road use, I favor a tyre that performs very well in the wet, since in the dry my old Pilots are really OK in 185 60 14 size. So the 021Rs will be my choice although the thread design is not really trendy smile.gif Pierre Link to comment Share on other sites More sharing options...
Geoff Dixon Posted January 15, 2001 Share Posted January 15, 2001 Have been using 32R's since last Summer, previously had Michelin Pilots. Can't speak for the 021's The 32R's are absolutely superb in the dry, in the wet provided you dont go mad they are fine.(My old BMW 3 series (1995) on standard road tyres was worse in the wet than the 7 on 032R's) Link to comment Share on other sites More sharing options...
murph7355 Posted January 15, 2001 Share Posted January 15, 2001 I found 021Rs a massive improvement in every respect to the Pilots I was running. Part of this may have been changing the size (185/60/14 all round to 185/60/13 fr and 205/60/13 rr) but most was the rubber I believe. The only area I'm expecting them to be worse is tyre wear, but I haven't been on them long enough to comment properly yet. I'm going to try 032Rs when the 021Rs run out now I'm hearing better reports of wet weather ability, but have also heard these run out quicker than 021Rs so may not be as practical for higher mileages. 021Rs are cheaper to buy so the cost equation is firmly in their favour over 032Rs... As Pierre notes, they don't look as good as 032Rs though! C7 AJM Link to comment Share on other sites More sharing options...
aideen Posted January 15, 2001 Share Posted January 15, 2001 Pierre, I thought you had a 40th anniv. car? How did you manage to get 14" wheels? Aideen Link to comment Share on other sites More sharing options...
EFA Posted January 15, 2001 Share Posted January 15, 2001 I heard CR500's are superior to ACB10s wet or dry. They are on my shopping list instead of ACB10's next time I need tyres.... ACB10's (due to their crossply construction) are very directionally unstable. Arnie Link to comment Share on other sites More sharing options...
Powderpuff Posted January 15, 2001 Share Posted January 15, 2001 Arnie, I think you'll find that CR500's are nowhere near as good at ACB10's in the dry, I'm sure Alex (I've got more sets of tyres than I can store) Wong would agree smile.gif Link to comment Share on other sites More sharing options...
StewartG Posted January 15, 2001 Share Posted January 15, 2001 Yoko 21Rs Great in the wet,good in the dry. Wear good 6-7000 miles. Cost cheap Yoko 32Rs Good in the wet, great in the dry. Wear OK 3-4000 miles. Cost OK ACB10s Poor in the wet Phenominal in the dry but tramline like mad and feel quite unpleasant on rough roads. Wear poor 2-3000 miles. Cost OK to expensive. CR500s Phenominal in the wet, good in dry but overheat under duress on track chewing up prematurally. Wear OK 3-4000 miles. Cost exessive. Link to comment Share on other sites More sharing options...
Pierre Gillet Posted January 15, 2001 Share Posted January 15, 2001 Aideen, this was the spec chosen for France in 1997. My car was built by caterham with the 40 th Anniversary spec., except for the "wheels": Mountney and minilite-style in 14 inches! I ditched the Mountney and replaced it by a Motolita, but kept the 14 inch wheels because they are OK for road use. Cheers, Pierre Link to comment Share on other sites More sharing options...
Richard Ince Posted January 15, 2001 Share Posted January 15, 2001 Paul I almost totally agree with Stuart G! I would rate the 32R as good in damp but only OK in the wet. In the 750MC where we have to use Yoko tyres we use the 21R for the wet. In the dry 32R. On a drying track 32R's will give a better time. However for a dry track day I would use ACB10 and a damp track the CR500's. I believe a new compound is due out which should improve the dry performance of the CR500's this year.

EFA Posted January 15, 2001 Share Posted January 15, 2001 Powder and Stuart Have you tried the really soft ACB10's??? I have noticed (and others have also) that R500's have phenomenal grip off the line, especially when I was alongside Jason when we all went to the Pod. He (initially) just dissapeared into the distance. My ACB10 expeience is with the A30 and A33 compound - do the A27's make a huge difference? I suppose it could be the R500 gearing - Jason had much the same everything except diff. Would his 3.91 vs my 3.38 make such a huge difference when you consider I have about 50lb/ft more talk than a R500?? I am confused.........

Darren Smith Posted January 15, 2001 Share Posted January 15, 2001 Yok now have an 032R super soft, (in addition to the original compound) which according to them (yok) will be better than the 021r in the wet. The size no doubt you require is probably not in the country yet but is due soon. Give these a try......somebody has to. Apparently next year an 040r will be available this being comparable with the acb10, Link to comment Share on other sites More sharing options...
Graham Perry Posted January 16, 2001 Share Posted January 16, 2001 Steward G has it right, I recently tested all 4 of these tyres with a rubber compound guage. Although not 100% reliable in terms of the indication of Grip levels, the 21r's were hardest, then 32r's, then CR500's and finally ACB's were the softest. At the same time I tested a couple of new formula one Bridgestones and was surprised to find that they use a harder rubber than all of these.

WILL FLY Posted January 16, 2001 Share Posted January 16, 2001 I'm just about to buy a set of 032s 185/60 HR 14 from George Polley, 306.15 for FIVE inc VAT & fitting & balancing (if you go to heathfield) or delivered. CR500s are 113.98 each INC VAT, so 569.90 for FIVE. You can virtually get two sets of 032s for the price of one set of CR500s. You pays yer money and takes yer choice, I know what I'm having.

Barry Posted January 16, 2001 Share Posted January 16, 2001 Will, Do you have a preference for which side any punctures will occur on? Bet you that the spare fits on the other side wink.gif Link to comment Share on other sites More sharing options...
Captainbilos Posted January 16, 2001 Author Share Posted January 16, 2001 Wow what a response! (I usually only get a couple) I think I'll give the 032R's a go. Reasonable cost and wear so they should last the summer. Many thanks Paul Ps. Good try Caterham Sales bloke Link to comment Share on other sites More sharing options...
WILL FLY Posted January 16, 2001 Share Posted January 16, 2001 Barry I know sods law will be operating. I'm going for left side spare on the grounds that the left wheels are near the kerb where all the crud ends up like nails etc. Also most circuits are right handed which mean the left side will get moe of a hammering. I did think of only getting four, but as I managed to pop a tyre of the rim when I span in Sweden and kerbed the rear left I thought it better to have a spare to get me home, even if I have to drive it the wrong way for a bit. I asked the Yoko man at Autosport if they were ok for short periods going backwards and he said yes but the rain shifting ability would be reduced.

Geoff Dixon Posted January 16, 2001 Share Posted January 16, 2001 Why not just buy 4 and keep whatever you have on the spare. Better still dump the spare and carrier and save weight. Link to comment Share on other sites More sharing options...

Pierre Gillet Posted January 16, 2001 Share Posted January 16, 2001 I read that the new lotus Elise use some kind of Bridgestone. How would they copare with Yokos? Pierre Link to comment Share on other sites More sharing options...
Graham Perry Posted January 16, 2001 Share Posted January 16, 2001 Arnie, Sorry I didn't get the compound number but was told, they were the softest available. Indeed they were so much softer than the CR500 that the difference couldn't be explained by guage error. Link to comment Share on other sites More sharing options...
Rory McLeod Posted January 16, 2001 Share Posted January 16, 2001 Isnt it illegal (UK) to run without a spare? Link to comment Share on other sites More sharing options...
