polainm Posted April 9, 2018 Share Posted April 9, 2018 HiCurrently wearing out Yokohama A-021R front 185 60R13 rear 205 60R13. What tyre recommendations are there for 155bhp with LSD on live axle in soggy Scotland? Studded tyres not an option. I will have change of underwear.Thanks!Matt Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted April 9, 2018 Member Share Posted April 9, 2018 There's a lot on this in the archives but unfortunately it's scattered: the most useful single accumulation of wisdom is probably "A021R to be discontinued".JonathanPS: Can't help with the underwear.

DJ. Posted April 9, 2018 Share Posted April 9, 2018 Last time I did the NC500 I was on Uniroyal Rain Experts with 125 bhp and a friend was on Avon ZZRs with 220 bhp. We had some severe rain to the extent that some roads were like rivers. My friend had a few more "moments" than I did as you'd expect but we both made it home safely.It is fair to say I actually enjoyed the wettest day while my friend survived it, but this was probably more to do with me having much less torque Link to comment Share on other sites More sharing options...
mark not max Posted April 13, 2018 Share Posted April 13, 2018 During our trip to Scotland last Whitsun, boy did it rain. One of the biggest storms I have encountered. I was on 048s (sadly my last set) with 200bhp and the other Caterham 888r with 135bhp. My advice would be to go with what you know, if you are comfortable with them.Have a great trip. It’s well worth it despite the rain! Link to comment Share on other sites More sharing options...
polainm Posted April 14, 2018 Author Share Posted April 14, 2018 Bugger. I have 185/60 r13 in front and 205/60 r13 in rear. Yokohama A539s I can get in 185 and A048 and R888R but the latter are too race/expensive. Selection of same tyre in 205 is virtually impossible. What am I doing wrong? Swapping rim size not an option. Any other recommendations that cover both tyre sizes? Link to comment Share on other sites More sharing options...
Wrightpayne Posted April 14, 2018 Share Posted April 14, 2018 185’s fine up to 200bhp.Are you running 6” wheels all round? If yes easy to drop to 185s on the rear. Ian Link to comment Share on other sites More sharing options...
Tony Whitley Posted April 14, 2018 Share Posted April 14, 2018 Kumho V70A? 235/45 rather than 205 and DT don’t have them in stock https://www.demon-tweeks.co.uk/Product.do?method=view&n=1790&g=250025&p=20063&d=124&c=4&l=2&utm_source=Google&utm_medium=Base&utm_campaign=Competition%20Tyres&gclid=Cj0KCQjwzcbWBRDmARIsAM6uChUHYgfqrSmpDgtnV5BqwQiZR1HzpXd21e35S2dFw7GZ0F_9N-fzwScaApw8EALw_wcB&gclsrc=aw.ds Link to comment Share on other sites More sharing options...

ZZS seem fine Link to comment Share on other sites More sharing options...
David Brown Posted April 14, 2018 Share Posted April 14, 2018 Son just back from a week in Gairloch with his family. Far from needing rain tyres, he was swimming in the sea on Monday and was barbecuing in temperatures up to 18C. Link to comment Share on other sites More sharing options...

RogerB Posted April 16, 2018 Share Posted April 16, 2018 I did a run up to Buckie from home in Argyll last back end with AO 48s on rear 13” 205s & 13” R888s 185s on front. I would have been quicker with an outboard motor on the back it was so wet. I have since discovered the tyres I bought the car with (AO 48s all round) where actually 4 years older than the car, now 11yrs old. In short I now have R888Rs on the rear which others say are good in the wet. So just waiting for all the rain to clear the salt off the roads so I can try them out.Roger.

polainm Posted April 16, 2018 Author Share Posted April 16, 2018 Rim sizes at rear, on special live axle set up. It's a Ford Escort 8397-7008 Quaife LSD with halfshaft upgrade and Ford disc conversion by JW Sevens in 2006. Don't really want to change this, and just had rims recently sprayed!It seems the 60 profile is difficult to obtain in anything other than 'classic' tyres, or track orientated ZZS/Rs or R888s. However the 55 profile seems more popular. Changing from 205/60 R13 to 215/55 R13 means the tyre diameter reduces by 9mm and increases in width by 10mm. Changing from 185/60 R13 to 185/55 R13 reduces diameter by 18mm and but width is the same. This effectively lowers the car at the rear by the car 4mm and at the front by 9mm.Aside from speedo errors and ground clearance problems, anyone else point to handling/ride problems switching from 60 to 55 profile?[edit] well it looks like it boils down to the Toyo R888®, as I'm sticking with the profiles I have. Demon Tweaks seem to have the best price, but for most things they aren't the cheapest:R888R - 205/60 R13 £105.37 each R888R - 185/60 R13 £86.94 eachAnyone know where I can get these for less?

RogerB Posted April 16, 2018 Share Posted April 16, 2018 That’s a good price. The best I could find for those size rears was mytyres at £103 last September, however I think they are more now. That’s not fitted!Roger. Link to comment Share on other sites More sharing options...
Derek Batty Posted April 17, 2018 Share Posted April 17, 2018 I se on some sevens nr cut slicks On some sevens must be a nightmare in wet Came Down past fort William couple tears ago lots of standing water was only doing poss 30 lucky hood up on passenger side water was comming up over back wheel arch aquaplaned straight over. Also last year comming back from portmerion just as got on motorway lots of road works was stuck on slow lane traffic solid. Hit very large puddle. No control of car whatsoever.

polainm Posted April 18, 2018 Author Share Posted April 18, 2018 Wow. 13" tyres sizes for 60 profile REALLY restricted! Add the 205r 185f mix and it seems I can only obtain Toyo R888R GG for £90 a corner.I've read mixed reviews on R888R in the wet. Obviously a 600kg vehicle with 150bhp+ going through a live axle with LSD needs some care in the wet, especially standing water. I think I would pull into a motorway cafe and sit out torrential downpour anyway, if faced with high speed water issues.Coming from a Yamaha FJR1300 I have respect for the contact patch of life, but just how 'bad' is the R888R (GG compound) in the 'normal' rain and when cold?

randybugger Posted April 18, 2018 Share Posted April 18, 2018 I went through the same search for alternative tires and settled on the R888R in the same sizes as yours and that have been fine in the wet Scottish mountains. Better than the AO48’s they replaced. Link to comment Share on other sites More sharing options...

polainm Posted April 18, 2018 Author Share Posted April 18, 2018 Thanks. Looks like the R888R GG has it. I’d prefer the wet benefits of CR28s but finding these seems really difficult. Link to comment Share on other sites More sharing options...
mark not max Posted April 19, 2018 Share Posted April 19, 2018 If you are settling on 888Rs you could call George Polley for a price. Not sure whereabouts you are, but they are in Manea. Link to comment Share on other sites More sharing options...
