021s and Roadtecs have pretty similiar round-shouldered profiles, they should work together pretty well- I ran a roadtec front and 020 rear for a long time and that was also fine. That's a terrible mileage for a Roadtec though, 5000 miles? My last one did about 9000 before i took it off to keep it for a spare, it's still the right shape and working well. You should get more than that from a Sportec or similiar never mind a Roadtec. Makes me wonder about tyre pressures...
