Has anyone used Dunlop Mutants on there X coming up to the time to change the rear tire which is a Roadsmart 1 and someone had said about a mutant on the rear ?

I do alot of back and forward to work which is about 25 mile round trip and had heard the mutant would be dead by the summer ?

I have narrowed it do to the Roadsmart 2 and the Mutant

P,s I am running a RS1 on the front would there be an iusse ?
