My new Oulanders, 650xl and 850xtp both came with ITP terracross tires, 26/8/14 in front and 26/10/14 in the rear. I’m looking and getting some spare’s and would like to stay with the same tires. I just found out that the 26/10/14 is supposed to be a factory size and my only choice to stay the terrecross’s is to go to a 26/11/14 or pay WAY more for the factory size. If I go with 11’s in the rear and 8’s in the front that seems like it would make my front tires really skinny in comparison.

Does that make sense and if so what should I do? Should I just run the 11’s on the rear and not worry about it or should I get wider front tires and how wide can I go on the factory front rims?
