My point precisely They are Hacking my behavior nicely, thank you. They perform well in sand as well. Whereas Softer compounds chop out real quick,like.
For the benefit of all; An hour ago I followed a vehicle to it's destination (Pity it wasn't the Beach) as it had a rather Odd appearance on a Strange looking Trailer.
It turns out that it was a young guy I had been chatting with last month and gleaned that his dad had built a Land Yacht a few years back. LAND YACHT!!! Is an understatement-----------------Big Time and I didn't have a camera with me. This thing is near 4.5mtrs long and and at least 3mtrs wide built from aluminum. The outer 750mm of each Axle bear is built in a Folding Wish Bone system that Bolts into place fro sailing it uses Ali Motor Bike wheels and sports a Catamaran Sail, this Beast is Massive and sits on a Purpose Built Trailer which uses a 300mm Ali Tube as its main chassis as well as Sail, Mast etc Storage. The whole unit is something to behold. I hope some day to take some pic's of it for posting on the site.

Probably no use to most on this forum but I found (and bought 3) these from EBay.

I needed to replace the club yachts tyres that I've knackered in the last few months and get a tube or two. It turned out cheaper to buy these than just the tyres and tubes separately Can't find any bearing adapters yet but they'll do to start the next yacht build - which means I need some more tyres and tubes At the worst I'll knock up some adapters on the lathe but $7.68 for a tyre, tube and hub ain't half bad.

Yeah! Col,
I do not want to burst your bubble but.
I am running them on Schrodinger's Cat, they are only so so the bearings are noisy and cut out pretty quickly. I ended up machining them out and fitting a High Speed Race fitted with retainer Clips, the clip let into the plastic of the Hub. They do the job now but are barely satisfactory. I have been looking seriously at a couple of Rims from

www.electricscooterparts.com/wheels.html

Front Wheel For All Razor Dirt Rocket MX350 Electric Dirt Bikes

They look sturdy and a different tire (Street tire) fitted should do the job nicely.

Always keep in mind that "Cheap is as cheap does" Quality will end up cheaper over time.

Check these out Nikrum. tboltusa.com/store/honda-50-z50-monkey-bikes-br-10-wheels-tires-silver-pair-p-2249.html If you mate them with a gokart race hub and small adapter plate they would work. Salty though.... but looking good costs$$$$. Am serious about doing something with scooter tires too, just haven't found the best route.

Unfortunately Ron, while some of us accept the risk we take and accept the outcome if something goes wrong, there are others out there who will run straight to the lawyers it something goes wrong and there is maybe a quid in it for them. I wish it was not like that but I guess its the world we live in today.

Funny you should say that. I've tentatively being looking at the construction of the old ('70s & '80s) Astralite wheels as a possibility... for all sizes. Rims are causing some thought but the hubs and ally sheet centres are easy enough with my small lathe/miller. I'm guessing that any failure in the placky 4.00x8s is in the hub. Trouble is I'm too strapped for cash to experiment currently.

Cheers Col

Aus has a point Col,
Why build a small OD Wheel when a larger Dia' will roll easier and freer.. Have you ever driven a Tractor with Large rear wheels and then one of those little Bone Shakers they call Ride on Lawn Mowers?? The smaller the wheel the Deeper a Pot Hole seems.. Haveing said that I wonder how a 2mtr wheel would feel[}:)] Gees! Hell of a YOT!
Ron
PS; Who ever heard or a "Farthing Penny" Land Yacht??

What is a pilot or race licence look like
We don't use either

when i was looking around i came across "Kenda" regularily. Anyone have any idea of it ??
