I just ordered an MT43 for out back on my DRZ. I'm running a tube now with no issues on a Dunlop 739. I ride desert hard pack and rocks. I've considered a Tubliss, but have heard mixed results. I do not run a rim lock now. If you have this tire, please advise what set up ie; tube/rim lock/tubliss you are running and how you like it. Thanks. See you out there.
