My Brian James trailer currently has 145/80/10 tyres on 3.5j rims. The it needs new tyres and the rims are getting a bit corroded (not just cosmetic)
so I'm looking at changing the lot.
It's always swayed a fair bit and the tyres just don't look up to the job, although thats what BJ designed it with and is within the load
ratings for. So I'm thinking of going to 195/55/13 on 6j rims like you see on some small plant trailers. I want to stick with 10" as the
ride height is OK and would be effected if I went to 12 or 13" whereas these are only fractionaly different overall diameter.
Can anyone see any downsides, other than cost and I'd need wider mudguards?
The problem I've had with low profile tyres on twin axle trailers
is that when turning sharp corners the tyres are being dragged sideways
and the sidewalls are very easily damaged on anything sharp or rough
such as potholes gravel car parks or the edges of manhole covers.

my brian james minno has the same size 10" tyres as you and is totally stable when towing even at speeds you shouldn't really tow at.
you sure its not something else causing it to sway about

It's a single axle trailer so doesn't suffer from the man-handling problems of a twin. I'm not 100% on the model but it looks like a
single axle version of the older Minno's. The bed is pre-drilled for both single or double axle positions. I've recently moved the axle
forward to the front axle position and then shortened it at the back of the bed. 2' less (un-needed) length makes for easier storage.
To be fair the swaying usually occurs when going a bit quick and then having to react to someone else doing something silly. Mostly I just don't
like the look of the 145's; They just look too small for the job.
Moving the axle forward will have made it less stable.
on my single axle trailer we fitted 12" mini wheels which allowed the higher rated 12" tyres and it was much better and with them running at
much lower than the max rate it also felt much more safe and stable unlike the 10s which were technically legal but near the rated limit.

never thought about it being single axle when you said it was on 145/10's. i always thought they would be on bigger wheels with only having 2 of
them.
not saying you wont be able to improve it but a single axle is never going to be that stable at speed. i was surprised at how much andyd's single
axle trailer with his westy on moved about when i was following him at 70, although he said it felt ok in the car.

Yep, typo I hadn't spotted.
Update... I changed over to the 195/5/13's and it's a big improvement both in ride and looks.
Biggest problem was finding mudguards that fitted. In the end I made some from the old ones and the top of a plastic barrel and they look pretty good.
