Mr G Posted January 24, 2005 Share Posted January 24, 2005 Im thinking of buying some 15 inch wheels for loony, fast road use (keeping the 13's for the track). There is of course the 500 tyre from caterham, but i've been told that the yoko 48's are a good tyre. Does anyone know how they compare, for road, possible track use and price.

Support Team Shaun_E Posted January 24, 2005 Support Team Share Posted January 24, 2005 I guess most people would say "Why buy 15"?" 13" rims will be cheaper and lighter, as will 13" tyres. Personally I'm using Yoko A048Rs because they are cheaper than CR500's and reduced the ride height less when I changed from Yoko A021Rs. I'm pleased with them for both road and track use.

KevSull Too Posted January 24, 2005 Share Posted January 24, 2005 I use CR500's. Not tried 48's yet but I understand that the CR500's last much longer (my last set were 11,000) so that negates any price advantages. 48's are said to grip a little better in the dry but CR500's are better in the wet. I'd rather sacrifice a little top end dry grip for any advantage in the rain! After all, most of my driving is road based and when do you honestly use the full potential of the tyres in the dry?? 😬You laugh at me because I'm different, I laugh at you because you're all the same. 😬 Link to comment Share on other sites More sharing options...
MikeW Posted January 24, 2005 Share Posted January 24, 2005 The 48's last longer, are faster in the dry, cheaper and the higher profile means that your speedo will be reading a bit lower. Not got back to back experience in the wet but grip is more than adequate. Personally I'd stick with the 13" wheels MikeW Mega Grad Link to comment Share on other sites More sharing options...

MikeW Posted January 24, 2005 Share Posted January 24, 2005 48's are about £60 ea. 500's are more like £95 IIRC MikeW Mega Grad Link to comment Share on other sites More sharing options...

rgrigsby Posted January 24, 2005 Share Posted January 24, 2005 Hmm you can buy CR500's direct from Avon for quite a bit less than that but it's still going to be more than Yoko's. I think my last set of SLR sized tyres was £373 inc delivery. The CR500's are lighter though! Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...

Alex Wong1697456877 Posted January 25, 2005 Share Posted January 25, 2005 I use 15"CR500's on the road - very pleased with them. When I tried the car at Cadwell on these tyres and wheels, I thought I'd try them on the track. I was very impressed at how good it was. Ok the 13" slicks I used in the afternoon were better, but not by nearly as much as I was expecting. They are expensive but the 15" CR500's are a very good setup for road and track use. Much better than you would expect from a 15" wheel and tyre. Haven't tried 048's though, and the saving is hard to ignore! Link to comment Share on other sites More sharing options...
KevSull Too Posted January 25, 2005 Share Posted January 25, 2005 MikeW, how long do 48's last then? As I said, I got 11000 miles out of my CR500's, if the 48's can outlast these then I'd be surprised (and looking for a set for my next change!) Mr G, this is worth a look here. A comparison between 21's 32's and CR500's done by Jason, he had his CR500's last 3 times as long as his 32's. 😬You laugh at me because I'm different, I laugh at you because you're all the same. 😬 Link to comment Share on other sites More sharing options...
Phil Posted January 25, 2005 Share Posted January 25, 2005 I did not want 13s so I forked out for some R300 15 inch rims and purchased four 195/50/15 toyo proxi TS1s, A1 spec, brilliant grip in all conditions, nice looking tread and a silly price as I am in the trade but check the price out yourselves with your local dealer.

neil.cavanagh Posted January 25, 2005 Share Posted January 25, 2005 I've got Toyo T1-S (the latest version) in 205/45 R16 on all four corners of my SV. Seems very good so far, and were £65 each fully fitted, which for that sized rubber is very reasonable! Link to comment Share on other sites More sharing options...
Phil Posted January 25, 2005 Share Posted January 25, 2005 Just had a look at blackcicles an online tyre supplier and Toyo Proxes T1-s 195/50/15 V are £38.80 each x4 = £155.20 plus VAT at £9.40 = £164.60.

frankyknuckles Posted January 25, 2005 Share Posted January 25, 2005 My 48's have lasted 4000 miles which includes 4 track days, 2 of which were airfiled days. I am down to the wear marks (which are now level with the surface of the tread so I presume my tyres are now illegal). But, below the wear mark, there is about 2 to 3 mm of tread left, so these tyres are still good for a few track days. I have also been running the 48's at 20psi all round, which I have now been told is far too high. The correct pressure seems to be between 15psi all round or 18 rear and 16 front. So I don't know if lower pressure will increase or decrease the wear rate Also, the Cr500's have a narrower (10mm less than 48's) profile on the front. Not sure what difference this makes? I also had to change the ride height when I changed from 500's to 48's. I'm not that bothered about the odd kg here or there, I'm sticking with the 48's. www.R300.net Link to comment Share on other sites More sharing options...
Mike C. Posted January 25, 2005 Share Posted January 25, 2005 Are those tyre pressures 'hot' or 'cold'? Mad Manx Link to comment Share on other sites More sharing options...
Ferrino Posted January 25, 2005 Share Posted January 25, 2005 Also, the Cr500's have a narrower (10mm less than 48's) profile on the front.I believe that this is just a peculiarity of the way the manufacturers measure the width or something - apparently 175mm CR500s are the same width as 185mm Yokos Lobbying Caterham for a new badge....

Phil Posted January 25, 2005 Share Posted January 25, 2005 I have found after a lot of playing around that the best for me and my car is 18psi all round, road use only. X/FLOW 1700 DD 1990 ROAD USE ONLY..SO FAR Link to comment Share on other sites More sharing options...
frankyknuckles Posted January 25, 2005 Share Posted January 25, 2005 the 20psi pressure I mention above is what I have been using for road driving. When on track, I also make sure that the pressure is also 20psi when the tyres are hot. I'm not sure if the 15psi all round, 18 rear and 16 fronts are hot or cold? If they are hot, what would you make the cold pressure for road driving? Maybe Dave Jackson can comment on this? www.R300.net Link to comment Share on other sites More sharing options...
ben7 Posted January 25, 2005 Share Posted January 25, 2005 I'm using 48's on 13's at the moment, had them for about 800 miles. FWIW I run them at 18 psi front and 16 psi rear. I drop them to 17/15 respectively for (occasional) track use. Both of these are cold temps, and for no other reason the Mr Polley told me that's what I should run! IMHO, I find the 48's too hard (or the se7en too light ) for them - I never seem to get enough heat into them. I bought them for road use and have found that they are not as good as 21's in the wet and nothing like ACB10's in the dry. Basically I find them too skitish on greasy roads. Again FWIW, I am going back to ACB10's and only using the car on the road when conditions suit. They are also seem considerably heavier (anecdotely from when I change tyres - I've never weighed them) than the ACB10's. Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted January 25, 2005 Share Posted January 25, 2005 They would be as theyres steel belted radials (I think) and the ACB's are x-plys. Link to comment Share on other sites More sharing options...
frankyknuckles Posted January 25, 2005 Share Posted January 25, 2005 Why would you have more pressure in the fronts ? www.R300.net Link to comment Share on other sites More sharing options...
Normans_Ghost Posted January 25, 2005 Share Posted January 25, 2005 I have a problem coming up. I've got ACB10's which have been on since August. About 4000 miles. I've had one warm day in the summer when they got warm enough to show me why I made the right choice. The "tramlining" is horrific and in the wet (and cold) they're frightening. BUT, the rears are nearly down to the wear bars and so, before long I've got to decide on another set or something else. In my quest to reduce the weight to below 500kgs (only 20 to go) I want to keep them for lightness. But everything says try '48's or CR500's I know if I ask for advice I will get lot's of conflicting views but so what, it makes for good reading.
