trailer tyres

[cheeny]

Hi all ive got a bayliner 1700 bowrider on its original trailer
with original 1984 american tyres but no size on them - been to a couple of tyre fitters but after trying a feww they dont know what fits, any ideas - should I try a trailer centre - wanted to get part worns as i only move it 100 yards to water few times a year!

Try a trailer centre by all means but a decent tyre suppliers I would have thought would be the best bet.

Go to an independent firm not one of the useless national ones. Take a wheel with you and they ought to be able measure it and get something that will fit. For the use you describe you may not need a perfect match with the originals.

Part worn ones is hoping a bit much if they are not a common size that you can get from a scrappy.

or go to a scrap yard with the tyre they have hundreds

Check the PCD of the current wheels

What does PCD mean? PCD stands for (pitch circle diameter), this is the diameter of a circle drawn through the center of your wheel's bolt holes. PCD is measured in millimetres and also indicates the number of studs or bolts the wheel will have. The most common fitment has 4 studs with a PCD of 100mm, hence the fitment 4x100.

Once you have the PCD you can go to a scrappy and find some wheels with tyres already fitted that will fit your trailer...

[/ QUOTE ] A bit more complex than just the PCD.
Stud or bolt size for starters.
The size of the central hole varies and so does the profile of the centre of the wheels.
Ok it may not be necessary to get an exact match for the use required but to some extent those factors may limit the options.

Stud and bolt sizes are all very similar, it tends to be on alloys that they vary more as some are sleeved or have tapered seats. I figured for a trailer that only does a couple of hundred yards he'd be after a set of old steel wheels and so centric seating and stud taper were less likely to be a matter for him...

Find a caravan breaker, take your wheel with you,he will find the right tyres for you. Trailers and Caravans have different hubs.

It sounds like the tyres you have are not legal. They should be DOT and E marked, and will have the size marked if legal. They could be an obscure American commercial vehicle size, but again, not legal in the UK, hence the supplier could not find the right replacement.
