19k and you sound disappointed? You gotta be taking the piss! ;DI got 20k out of a Michelin PR3T front, but the rear did 12k. PR4T rear did 10k (that was actually disappointing). A3 set I got 16k and was very impressed. A2 set was about 11k.Another option for you would be Heidenau. Got 10k from a K76 rear, done 9k on a K60 rear and it's not finished. It's a more agressive option for off road, the compound is hard and long lasting, but the trade off is I hated the wet road grip, found it pretty slippery.Conti Trail Attack might be an option, I think there is a new 2 version? Trying the original, I was one of those with a shimmy at any speed (some people reported problems, others said no problem, all 12GS) so I sold them to Neil at Experience and he got 30k ish on them.I've put a PR4T front on 3 weeks ago and done 3k so far, and just replaced the PR4T rear with a PR4 (you can get the correct size, just the compounds are different) so let's see how that goes...
