    Has anyone put larger rims and tires on a jayco 1207? Standard size is 205 65/10.

    What year? Mine is a 1996. I put 205/75R14 on mine. It involved a new axle, 4" lift blocks, cutting and welding on the frame, extending the step, and new stabilizer jacks.

    The problem with larger tires is the camper has a GAWR OF 2210 LBS. The tires must carry at least 1105 lbs each. If you weigh the trailer, you will find its probably very close to being overloaded anyway, so you have very little safety margin. Try shopping for tires that meet that weight capacity. To go larger you must go to 185/80R13 LRD or bigger. That is a hard to find size, so might as well go to 205/75R14. You'll have to cut the frame for clearance either way.

    If you want to go to a radial, there is a 12" Tire that comes in a LRE if I remember correctly that will carry the weight.

    It's a 97. I don't have time to do the lift, axel flip etc. was hoping for a 12" or something that could carry the load. Guess I will stay with the 10's

    Just looked. ST145R12 LRE will carry 1520 lbs. That is 400 lbs more than the stock tires. They are approximately the same outer diameter, so they should fit. They are narrower than stock and also radial, so they should run cooler. They look to be a good alternative.

    looking at a'95 jayco 1207 today, the small tire thing is problematic, as the reason I would buy this is to haul 1100 miles to Montana, and take down National Forest Roads. Fix_It or anyone else that knows......rather than rework the frame like you did on your axle replace, would it be possible to get a wider axle, extending the wheels beyond the camper and adding fenders? Our horse trailer is set up that way.

    While anything is possible, the axle is only rated up to a certain overhang distance (hub to spring or frame bracket). The frame is so far in that the overhang would be too much.

    If you dont have time to do a lift, you certainly don't have time to fab new spring perches on a wider axle.
