I have a mini sized Frontier Easy Entry pipe cart. I am looking at a 10h pony on Monday and am hoping I can use my mini B harness with maybe some new pieces and my mini cart with larger wheels. The ride on the cart is improved with the pnematic tires but I'd like something more durable than bike tires like it has. Any ideas on possibilites? I also use the cart and harness with a mini jack so I don't want to make it totally unusable with him.
You need to find someone who is mechanically inclined.
Find 2 matching motorcycle wheels (preferably front as there is less brake to be removed) and then 2 motorcycle tires.
Go to a local motorcycle repair shop --they should have rims around or if not, be able to send you to a m/c shop that does.
Used they go for anywhere for 50 to 100 bucks each. Tires maybe 10 if they are used.
Then make a trip to a bearing shop and tell them you need a bearing that is sealed and has a center to fit your axle which should be 5/8.
Take the bearing and the rims to a machine shop and have the bearings pressed into the wheels.
Put on cart, tighten just right and bingo, you have a nice ride.
I know this sounds like a bunch of work and expensive, but once you do, your ride will be better and these rims and tires will just about last forever. Your rims may well last longer than your cart.
I put a lot of miles on carts in the woods--and other than one flat tire due to a metal barb which made it through my tire and punctured the tube--these hold up and give a softer ride to boot. I am not worried about the tires rolling off the rims ever.
Just about everyone I know who bangs around in the ee carts down here have done this. We can run the tires just a little low on air, it gives a softer ride yet and floats on the deep sand we often encounter.
New and replacement horse, pony, and mini cart wheels for great prices!
We purchased "Heavy Duty" horse cart wheels from a respected online cart company, only to find that the exact same wheels were being sold locally for over $100 less! To see the whole story and links to where to buy horse, pony and mini cart wheels very inexpensively, please see our website page below. We have 20", 24" and 26" sizes listed for both Pneumatic and Flat-Free tires:
While these wheels and tires are considered heavy duty, they are not suitable for extremely rough terrains like going through ditches, uncleared wooded areas or over dangerous rocks that could damage the spokes. You would need to purchase the more expensive steel spoked wheels for cross-country driving.
my husband says that the front dirtbike wheels are 21" and are common and cheap. And you can get tires for them in a "Street tread" or "Enduro tread" (without the knobbieness) Also 19" tires can be cheap because they are also common... SINKO is a brand name he's suggesting, and by cheap he means $80 or so.
If saving money is a goal he suggests a motorcycle salvage yard or craigslist.
I recenly replaced the tires on my EE cart which has the heavier duty welded barstock spoke type wheel- but a rim that is sized for a bicycle tire. There is a cruiser bicycle trend right now called "Fat" which uses special EXTRA wide tires. I just got a set of these and they LOOK really cool on the cart- but I haven't taken it for a test ride yet to see how they change the ride. You need to be sure you have clearance for them if you just add the tires to your current bicycle wheels.
Also, I'll just mention that the sidewalls of these specific Fatty-O tires seem kind of flimsy- so I don't know if I'd want to drive in a pricker patch or even a field of stubble- I think they would be easy to prick with a tall stick. I think the treads of the tires would be great on sand or gravel. They are about 2x as expensive as standard bicycle tires, but much less than dirt bike tires. By the time I got the innertubes the pair was about $100
