frankyknuckles Posted January 6, 2005 Share Posted January 6, 2005 Due to an already very busy calendar for 2005, it looks like most of my blatting this year will be on the road with an odd trackday thrown in for good measure. I have been running Yoko 48R's on 13" wheels (8" rear 6" front) and the time has come where I need new tyres. If my bad memory serves me correctly, I have managed 3500 miles on the 48's and 4 track days. I suppose for this year I am after value for money, so I'm considering if 500's (even though they cost more) will give me a longer life span? The 48's are a medium compound, but I think the 500's are a softer compound so I'm a little confused on the potential wear rates.

robmar Posted January 6, 2005 Share Posted January 6, 2005 the cr500's are a lot more expensive I think you will struggle to get the 175's for I doubt you will get double the life out of the cr500's! and they have a tendency to wear quickly on hot trackdays when pushed from my experience... there is a new softer compiund coming out for the racers but this sounds even less suitable. I have never used 48's but for VFM I think they may be best Link to comment Share on other sites More sharing options...
rgrigsby Posted January 6, 2005 Share Posted January 6, 2005 In theory the CR500's will last longer but if you throw in a few track days I suspect it won't be that much more. As RobMar says I reckon the 48r's will be better from a miles/£ point of view. Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
ponant Posted January 10, 2005 Share Posted January 10, 2005 l have CR500 195/45/R15 on a 1.8 vvc , NOT ONE TRACK day, they have 4.600 km ( +- 2.800 miles ) almost finish 🙆🏻 another 500 miles to go... Link to comment Share on other sites More sharing options...
MikeW Posted January 10, 2005 Share Posted January 10, 2005 48's are IMHO the best bet. In theory they will actually last longer ( wear rate index is 3x that of the 500's) and they are a lot cheaper. Having recently changed from the 500's ( 48's specced for the Grads this year) have been very impressed so far MikeW Mega Grad Link to comment Share on other sites More sharing options...
Tiff Posted January 11, 2005 Share Posted January 11, 2005 My first set of CR500's did 6,000 miles including 8 trackdays - albeit the first few fairly gently. Link to comment Share on other sites More sharing options...
DOD7 Posted January 11, 2005 Share Posted January 11, 2005 One point you did not mention (maybe you don't care) is that the CR500 are known to be very unreliable on the wet. Link to comment Share on other sites More sharing options...
caterhamnut Posted January 11, 2005 Share Posted January 11, 2005 uum - no experience of CR500's myself, but I think many people might disagree with that DOD7? Big update! here 77,777miles in 3 years Link to comment Share on other sites More sharing options...
Myles Posted January 11, 2005 Share Posted January 11, 2005 Yep - never heard that before... One of the great things about the CR500 is that it doesn't dramatically change character between the dry and the wet - it retains a high amount of grip and doesn't (in my experience) become unpredictable... The only 'issue' I can see is that the tread-depth is very shallow (6mm?) to start with - so it's never going to be terribly happy in standing water. Project Scope-Creep is underway...

robmar Posted January 11, 2005 Share Posted January 11, 2005 IME CR500's are better in the very wet than 32's on the road, no expereince of 48's on a greasy lightly wet surface there isn't much difference rob Link to comment Share on other sites More sharing options...
Mark Piper Posted January 11, 2005 Share Posted January 11, 2005 My CR500s were ace in the wet, as were my 21Rs though.....my current ACB10s are a different story though. I've heard that 32s aren't good in the wet weather (Gary G told me that, though...) ;-) Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted January 11, 2005 Share Posted January 11, 2005 If I had to choose one tyre only, I'd use CR500's - 15" CR500's seem to work well in most conditions - I used them once at Cadwell and kept up with a few slick shod cars without too much difficulty. No experience of 48's though. CR500's were ok in the wet - better than 032's, but never had a good tyre in the wet - one day I might try cut slicks butCR500's have been they best wet tyre I've used so far.

neil.cavanagh Posted January 11, 2005 Share Posted January 11, 2005 getting a little O/O but i think 032s have a slightly un-fair bad rep in the wet. i agree that standing water is an issue but otherwise they are grippy and predictable on very wet tracks. i've done two very wet track days (both in Wales!) and have managed fine with v. worn 032s!

Apothecary Posted January 11, 2005 Share Posted January 11, 2005 I have CR500's at the moment and am also thinking about the AO48's when its time to change (soon) for road use. Is there much difference in weight ? Link to comment Share on other sites More sharing options...
caterhamnut Posted January 11, 2005 Share Posted January 11, 2005 I *think* that the Yoko's are quiet heavy compared to CR500's and ACB10's. Big update! here 77,777miles in 3 years Link to comment Share on other sites More sharing options...
MikeW Posted January 11, 2005 Share Posted January 11, 2005 Got both, Yokos are heavier and they are 60 profile as opposed to 55. Run the pressures 1-2 psi lower than the 500's as well. MikeW Mega Grad Link to comment Share on other sites More sharing options...
Jason Plato Posted January 12, 2005 Share Posted January 12, 2005 205 32R is just over 2Kg heavier than a 8.2" ACB10 Dave Link to comment Share on other sites More sharing options...
Nick Green Posted January 12, 2005 Share Posted January 12, 2005 Neil Cavanagh, I think I need to add a small caveat to your comments. You talk of TDs in Wales. I am presuming you mean Llandow here. In that case I would agree that the wet grip of 32Rs is very good, though I think that is more down to the tarmac at Llandow. I've done wet sprints at Castle Combe and part-worn 32Rs gave me no confidence at all, and that was avoiding the puddles. If you mean elsewhere in Wales, ignore comments above. Am surprised to hear that CR500s might not be much cop in the wet. I thought that was what they were particularly good at. In fact, given my Combe experience above, I'm thinking of getting CR500s as track/sprint tyres, as it seems like 50% of the sprints I do seem to be wet at some time, and I'd like better grip in those conditions. I don't feel I'm good enough such that the extra second or so of dry track performance available from 32R/48Rs will make that much difference to me. Only one way to find out...

stevefoster Posted January 12, 2005 Share Posted January 12, 2005 I find my CR500's better than the Yoko 021's that I replaced them with. I was out in the big rains that came in Nov and had to drive through very deep water / standing water at speed. So much so my oil pressure warning light started to glow and water came up though my cockpit drain holes! Doesn't normally do that. Driving normal the 7 was sure footed and predictable. Over use of the right foot ~200bhp and 205's / 8" rims could of course have an affect!

neil.cavanagh Posted January 12, 2005 Share Posted January 12, 2005 Nick, was LLandow and Anglesey. Both fully wet track but without standing water, where I agree the 032s will do pretty badly becasue they have very little, and very shallow, tread.

duffym Posted January 12, 2005 Share Posted January 12, 2005 I have 4 year old yoko 520s on my seven 195/50 15s. Will yoko 048s make a big difference? At the moment I have no traction/rear end grip unless I am gentle . Not gentle v often 😬 If they will are 13" ones better than 15"?

Tiff Posted January 12, 2005 Share Posted January 12, 2005 I know folk who take CR500's to trackdays as a Wet tyre. My impression from reading blatchat is that they are much better in the wet than a more sticky "dry" tyre like a 32R. Link to comment Share on other sites More sharing options...
Graham Perry Posted January 12, 2005 Share Posted January 12, 2005 Duffym, Yes and Yes is the answer. Except perhaps in the wet where the 520's might inspire more confidence Link to comment Share on other sites More sharing options...
duffym Posted January 12, 2005 Share Posted January 12, 2005 graham , thanks! If 048s are worse than 520s in the wet eek ❗ ❗ I havent driven the car on warm dry roads having bought it in late October so I dont know what its like when there is some grip. Its amusing but slow in the current conditions. I presume then that Cr500s are better in the wet?
