It's sometimes easier to help if you add your machine and your mods to your signature so everyone can see exactly what you have.
I rode with a friend who had a 350 ES with 26" Mud Bugs and they worked fine, no rubbing. I am not sure, but I don't think he had a lift, however I'm pretty sure he only had 26x9x12's and 26x10x12's. Your tires would be pretty close, but you might have a little rub.
