Should out last the PR 3s with ease . If I have any doubts about the trail max it’s the lack of dual compound rubber . Michelin seems to have it well developed . I get 18k kms from Annie 3s if the road is a bit twisty. Good to hear you got good mileage from the PR3s , I have the Road 5 s on the Thruxton R . They are supposed to be longer wearing than the 3s but so far not so sure .
