Are you running bias or radials?
Another wrinkle in the mix for me was switching from a PUP with 12" wheels to one with 14" wheels. That was a major upgrade in construction, tread width and diameter, etc. You would probably see less of an improvement going from a 13" to a 14" wheel but it might be worth it.
Your 13" tire outer diameter is 24.1" and a 14" wheel and tire would be around 26.3" diameter. From the axle to your wheel well, you would loose right at an inch of clearance. If you have the room (or add an axle over/under conversion) you could do it. It would help with the typical Coleman/Fleetwood low clearance on their PUPs.
Last 3 sets have been radials, prior to that, I think they were bias.
Hmmmm ... I ruled out the 13" to 14" conversion last time, based on cost. Now I am not so sure. eTrailer.com has Kenda brand ST215/75R14 tires w/ wheels for $140 so 3 would be $420 with a 1870 lb rating at 50 psi. I will have to study the trailer to see if I think a 1" lose in clearance would be a problem. Has anyone done this with a Colewood trailer of similar size?
