I've got a little three rail motorcycle trailer that I bought new in 1972. Came with 4.80x8's, at some time along the line I put 5.60x8's on it. We towed that thing way too fast for many years, and never failed a bearing. I always kept them greased of course.
I did destroy a few tires though ! Every one of those tires that failed, did so at highway speeds, and every one of the was totally destroyed by the time I got pulled to the side of the road and stopped.
I tow with a Dodge Cummins dually. This little trailer is a speck to it for towing. I want to run 68-70 mph so I guess I need to buy a spare tire.
If there is any way you can do it, given the four hole hub and whatever clearance issues, I would put the largest diameter radial tire you can possibly fit.
I'll no doubt start a firestorm here, but I would MUCH rather have some sort of 13" car tire on there than ANY st tire.
These rims are 12inch and a 5 lug pattern not 4. I can put passenger tires on this trailer which would be 155 x 80R12. They would be rated at 108mph hwy speed which sounds better to me. Those little tires will be burned off in no time. Bearings may be an issue, however most people's experiences don't dictate that.
