i was disapointed in the wear life of the mudlites. about 800 miles

 

I have a 2006 grizz and need new rims and tires.

I am debating between the Kenda Executioners and the Big Horns. In either case i am planning on delta d rims. I ride 60% dirt, 40% mud and snow. Wear life is important to me.

I would like to know 1) which i should get; 2) what size width and hieght could i go up to without having clearance issues on a bike that does not have a lift kit; 3) can i get the rims with an offset that is an inch further to the outside in order to make it less tippy?

your advice is appreciated.
