Another wee thought - do you have any other trailers?
I am looking at re - hubbing my (unbraked) box trailer to take the same wheels / hubs as the (braked) rib (I specified 10" hubs for the RIb - yes the higher load rated tyres are slightly more expensive, but les so than removing bits of A- frame every time I put it in the garage! - & also makes launch so much easier as it normally floats off before the car is anywhere near the brine.....but I digress)
The box trailer has oldschool Mini Hubs & rims. Was great 20 years ago, but the rims are getting harder to come by and the current ones are slowly rotting (as was the way with a lot of BMC's output!
) As the suspension units are stiffening up, I am planning on replacing the whole shebang, so that I don't need to worry about which spare bearing set I just picked up for that jounrey...... and also give more flexibility with spare wheels and replacing tyres should I get a puncture......
