I need to replace the tires on my 12' v-nose single axle open trailer. I have heard that 13" tires are supposed to pull easier and handle better, Floe has made them standard on new trailers I believe. Does anyone have any experience with upgrading or pulling with both 10" and 13"? I am curious if it is actually better. Right now I only need 2 new tires so if I switch to 13's then I will need a new spare too, there goes another $100... Also I am worried about clearance. My trailer is a 99 so I don't believe they were using this size back then. Any advice would be appreciated.
