An elderly gentleman at our club who is a former plumber has a GP trolley made from old gas pipe. A few years ago he tried 14" car wheels and hubs. He changed these for aluminium motorcycle wheels. It cannot have been a success as he has reverted to old pressed steel wheelbarrow wheels. The theory was that bigger wheels would be better and overcome extra weight with efficiency of diameter. I have sort of balloon tyres, like a thick tube on my trolley. Has anyone tried these bigger non pneumatic wheels that are usually yellow?

MM. re plain rib vs block tread.
For your stated application of mud/stone I would go for a block traction style of tread. I say this as a man and boy agricultural type; yes it is not a driven axle but on a slippy surface a plain rib is more inclined to sink in a bulldoze a bow wave rather than turn, a tyre with some cross lugs stands a chance of biting the surface, keeping turning and staying on top. 🚜 |

Some of our guys are using the jumbo trolley tyres linked above, but I do wonder if those big tread blocks don't raise the rolling resistance on concrete unnecessarily (c.f. MTB vs road bike tyres).
Simple circumferential ribs such as the standard trolley tyres have would suffice - we don't actually need traction or braking out of out trolley wheels, after all!

I have always used cycle bearing white waterproof grease a couple of times a year to keep them wheels rolling as smooth as possible; it does make a great difference.
When I had a dart 18 I had a trailer with huge tyres for going over sand and shingle; I think it was called a Euro trax trolley but don't know if those wheels will fit a "standard" dinghy trolley. It is a joy sailing somewhere with proper slipways all the way into the water and concrete hardstanding to pull out onto as oposed to huffing and puffing over sand mud and shingle  |

Those 'off-road' tyres appear to have a larger rolling radius than the standard ones, which would pose a problem for some where the clearance between wheel and hull is not that great. I think this would affect mainly twin-cradle trolleys where the main cradle is not above the axle line.
I know that when one of the inserts on mine wore out the tyre was just rubbing on the chine. |

Agree on pressure Gordon.
I have put discarded road tyres on my trolley wheels for better puncture resistance and longevity but do have to exercise some caution as the plastic wheels will only take so much pressure before you "blow the bl**dy rims off"

We put the larger wheels (RS USE THEM FOR THE ENDEAVOUR)on our rib trolleys after the extra weight of the 4 strokes kept destroying the narrow ones and they have been really good.
On a beach I think they would be really good. Most important thing in the narrow ones for on concrete is keeping the pressure up. |
