I have a pugs and I had a set of standard wheels built for it so I could use 2.25 Nokia studded tires. That allows me to take one bike and two sets of wheels somewhere and ride Winter trails with the pugs tires and swap to studded tires and ride on icy roads or other icy conditions. With the offset front wheel you'll need to use a rear wheel kind of build even for the front. The pugs along with a second wheel set is a nice thing and very versatile. I do have a "regular" mtn bike but this way I can just take one bike...
