Normally at the start of every trip I swap out the tires the week before departure, just to be sure there are no tire related issues, and it has worked out well. Last year I swapped in Anakee Wild tires, soft radials, and they worked out great, about 6500km's, but after getting home the rear had a serious bald middle flat spot, and had to be swapped out. I put on a Mitas E07 Dakar as it sounds like this tire may do better on a long trip. The front tire though still has a lot of life left in it. My initial thought was to swap it out too, so I ordered a Mitas E07 for the front and it arrived today, but looking at the tread, the Wild tire has about the same left as this new Mitas has. Now i'm thinking of keeping the Wild on there and swapping it out when I get home. Is that dumb? My trip in June will be about 7500km if I don't have to turn around early like I did last year, so that front Wild will have about 14k km's on it at the end. There will be a lot of dirt as I am heading up the Dempster. What do you think? Keep it, or swap it out?
