Razor 900 tire size

Hello I am trying to find the right tire for my 2015 Razor. Nikal has been working with me some and I appreciate his help. I emailed GMZ about different sizes of Cutthroat and they said they were not planning any changes as of yet. So my question is, I have 26x8xr12 front and 26x9xR12 rear. It is almost impossible to locate a set of tires in something that has more ply’s and a closer tread pattern with side wall protection in my size. So will the 900 accept a 26 or 27x9R12 on the front and rear? I do not have EPS and thought I might run into harder steering at low speeds because of larger ground contact patch. Also, will I run into any turning radius issues from rubbing the control arms or front end parts?
I just can’t find a lot of choices for my existing size. I am trying to not have to go 14" wheels but it would give me more choices. I would like to keep the un-sprung weight of each wheel and tire as light as possible. I just trail ride in the desert and that means sharp rocks that the Polaris PXT can’t handle. Please help me on clearance and size issues!!! Thank’s:question:
