Using these on a BMW 325ti.
The RT is very quiet and has good initial bite on turn-in. However, it's very non-progressive in its behaviour - initial grip is strong but this is then given up far too quickly.
They may suit overweight, nose-heavy FWD cars very well, due to that strong initial grip on turn-in and the good ride quality, but on a RWD car they're mediocre at best - it's very difficult to get a progressive slide out of the back end. You get understeer as the back end grips, then snappy oversteer as it gives up. Mildly amusing as long as you have lots of run-off and a forgiving car, but on, for example, an S2000, they'd be terrifying.
They're a poor show for Dunlop, especially given the price is on a par with the current Goodyear Eagles. I've run two sets of ancient and theoretically inferior Goodrich G-Grips on the same car, and even nearly down to the cords, they're progressive and easy to find the limit with. Not so the Dunlops.
