Looking at buying some different tires for my bike. As most of you know the ones that come with it are 8" wide in the front and 10" wide in the back. Is there a problem with buying four tires the same width????? I really don't wanna go to wide in the back cause I don't want to start slinging mud on everything that would negate the fender flares I bought.. was thinking about 26x9x12 tires all the way around. Just wondering if there are any downsides to running all four tires the same width like that.
