I can now say the (In my opinion) best rubber for grip in the wet dry cold and hot is the Toyo R888, the overpriced Michelin cups just have you skating around fighting for grip in the hi revs, the run flats are for marking your territory 11s got 50ft on my drive, PS2 are a good long life rubber, but the Toyo R888 are so much better it is hard to get them to slip on a dry hot day
I haven’t run any other rubber so that’s it, also note the cups were not at full temp as they only have 1000mile life I wasn’t going to spin them too much to warm them up
Keep driving

Having seen the result of the combined effect of cold wet roads, and Viper power on a set of R888's, first hand, at rather too close than I would have liked.. The only thing I will say, is yes, they are good when warm and sticky, but be extremely careful when they aren't.
you have toyo dave 
t i'm on 900 miles and something, i cant afford a new set yet!GTSDave said:

I dont think I would trust any tyre on the Viper in wet conditions, I remember being on a semi dry road years ago going to one of the first Viper meets at Silverstone I was the passenger in an RT/10, we hit a puddle in the middle of the outside lane on a dual carriageway the car aquaplaned immediately! on new Pilot Sports Just as well the road was dry a couple of yards ahead I had never experienced that before! Still the day got better and better when Sir Steve turned up with his new purchase of Justin (the GT2) and he gave me a lift in him to the circuit

erm.... +1 ...end of life R888s that is. Kumho V70a s are crap in the cold too - strictly for getting to the track for their entire life to be used in a day... +they come new with just 3mm starter tread on half the treads (unlike the R888s). Everywhere i've read in the last 2 months says all Viper (rear) size tyres are crap in the cold, even 'summer' PS2 tyres - just hope my imminent set last for ages for future rd only use. Wonder, when the Super sports are eventually/ever made in the 335/345 size, will they be any better in the cold; the PS3s too. Bridgestones are said to be ok initially put appalling once half tread has gone...zs said:

I doubt the PS3 or super-sport will be any better in January, they are summer tyres of 345 width with 400-600 bhp and 500 odd Lbft tq. some will be better than others but forget full throttle in jan, Its hard enough to keep traction in July FFS. While i have not tried standing water or snow and didn't expect much in the first place, I have actually been really impressed with the cups through winter.
Bottom line in a viper is always to read the road and drive to the conditions.
