Pimping my trailer at the moment and wondered if any of you good towing folk know where I could get some 9 inch hubcaps? Google and fleabay both proving fruitless at the moment...
Wheel trims or hub caps whatever you like to call them are actually a VERY BAD IDEA. There was a case of a motor coach operator who was in court because wheel nuts came loose, studs broke and a wheel came off. The coach crashed and overturned and people were killed. The state of the nuts had never been noticed because of a chrome hub cap. Nowadays most coaches have the wheel nuts exposed and little plastic pointers are fitted to see whether the nuts are coming loose. Now do you really want to fit those hub caps? If you do and you have enough room for 10" wheels the classic Mini wheels are quite good. Different length studs are available and if you use a stud slightly longer than standard there will be room for a lock nut. Be warned that at above about half a ton per axle the nuts on the left hand side may begin to loosen. If this happens Loctite threadlock will hold the fort but fit new studs and nuts as soon as possible. Longer studs plus a Nylock nut on top of the wheel nut will cure the loosening problem but really one should consider better running gear if the problem persists. Avonride suspensions for the classic Mini are rated to 550 kilos per axle. Meredith & Eyre units would do 650 kilos but at this kind of weight you don't want old rusty nuts and studs as they won't stand the torque needed to stop the nuts from unscrewing. Good luck and don't forget the threadlock.
Almost forgot to mention it. There is now a British company making wheel studs with a safety feature. The stud is like a normal stud but it is longer. The elongated part is narrower than the main part and it has an opposite handed thread to the main part. AFAIK they are only made in HGV sizes :-( still there is always the lock nut idea and of course thread-locking compound. If you cannot get thread locking compound and things are desperate there is always Superglue. I had to use this on an Erde 142 trailer that I bought. The seller said "When its empty it rattles a bit but its OK once its loaded". The rattling seemed to be getting louder and when I checked it was the trailer coupling coming loose (one nut was about to fall off!) Erde bolts cannot be tightened properly because the thin walled tubing will crush but the problem is easy to solve. Obtain a bit of old galvanised water pipe or conduit pipe. Get a friend with a lathe to machine lengths of pipe that will just fit inside the rectangular hollow draw-bar where the bolts go through. Spray with cold galvanising paint and assemble. The bolts can now be tightened well-hard. The same dodge at the tipping pivot is also a good idea. One problem with Superglue is that it makes the nuts very difficult to undo unless they are warmed with a blowlamp.
i built my own trailers,still have one 6 x 3 re-vamped each year.it is now over 30 years old and looks really good.best option is to go for old mini wheels 145 x 10,better payload and wheel trims are easy to find.car scrap yard is the best place to find them.you may need the hub and bearings and brake disc to fit.you will need three wheels.
------------- the only silly question is the one you do not ask.
