Personally on my Ep3 I thought they were crap, car came with them and they were hopeless.
Don't scrimp on tyres, a crap tyre ruins the car, ruins the handling, ruins the traction and therefore power, ruins the rider and ruins the brakes, and on a car such as the DC5 it is all the more noticeable.
Bridgestone RE070 225/45/17 are only £80ish each are a fantastic tyre, brilliant grip, and very good in the wet I find, not too fond of standing water though. Goodyear Eagle F1AS2's and Continental Conti 5's are very very good all round tyres too.
