'Cause I'm trying to get an accurate handle on just how long a front 705 will last. And yea, I know,,,,, tires don't have to be replaced in pairs. And that's exactly what I was commenting on. My front will have 16K miles on it when this 705 on the rear goes away and while I really want to use it completly up, I don't want to live with a worn front and have a knobby on the rear. Nothing ground shaking and it isn't rocket science, was just thinking out loud,,,, or typing out loud as the case may be. My DL650 uses a 17 rear so the choices in knobbies isn't no where near that of your Husky. I've tried the Big Blocks and now I have a second rear wheel that I bought just to be able to readily swap to knobbies and it has a TKC on it. Still have a pretty good front Big Block so that's what I'll be running for knobbies,,, least untill that TKC craps in about 2.5K miles.
