I tend to stay at the cheapest end of the range for Drifting. Its more about the quantity than quality when your practicing although you find the remolds tend to come apart in chunks, delaminate and split a lot easier than better makes. In a ideal world you want a pretty hard tyre but not to expensive. Capitol tyres are a nice choice if you got the cash otherwise scrapyard for a search about (old tyres tend to go harder through age + scrap prices!) although sat I used brand new Pirrelli Drago's and found them to be excellent in the dry. The drift was harder to start due to higher grip levels but very predictable once starting and you could safely carry a lot more speed through. They lasted a good couple of hours before I was onto the cords. A real nice even wear patern too, no clumps or chunks coming off!! I use Yoko's up front, lovely tyres, plenty of grip and very reliable.
I bought a set of 3 17's off ebay (no.4 was destroyed in an accident) for 9 quid with Yokos on. I use 2 of these on the front of the Drift car with the 3rd as a spare and 15's on the rear (usually with crappy ford / pug alloys) If you check the scrap yards many of the alloys have good quality tyres on + when you have destroyed the tyres u can weigh the ally in!!
In my road, track and rally cars over the years I've tryed plenty of different types over the years and for daily driving (spirited!) I always prefered a brand Techinks. They do em at spondon tyres in Derby and for a RS turbo they fit 4 for a 100 quid! not bad at all, they as good in the wet as the dry, never let me down!! ****e for drifting, bit to soft, clump apart.
Yoko's and pirellis were my tyre of choice for many years before using the technics. I suppose they just edge it over the cheaper tyres but when you buy 4 for the price of 1 I think the difference is so small and the saving so big i wouldn't bother unless I was running more than 200 BHP or regually punching 140+.
Will post some photo's on the different wear patterns after drifting this week so you can see what the difference is.
The top of the line tyres are on the whole, better than cheap tyres , some being heads and shoulders better, but theres often no need to put these on your car unless you are competing at top level, and it's a better feeling when u see that 6 inch nail hanging out your new technic tyre than a brand new Michellin!!!
