Marathon 4.80/4.00-8" Pneumatic (Air Filled) Tire on Wheel, 3" Hub, 3/4" Bearings, Ribbed Tread

I used this on my contractor wheelbarrow from Costco when the original tire split open and the tube failed. I was having trouble finding the size I needed - a 4" hub and a 1" axle, 15.5" tire diameter on a 8" wheel. I called Marathon and they will ship out conversion packets. I bought this wheel and they sent me plastic 1/2" spacers and 1" rings to replace the bearings at no charge. They arrived via first class mail in 3 days.If you aren't sure what you need, take your old wheel off the wheelbarrow and measure the left-to-right length of the hub (the total length side to side of the metal center piece that the axle goes through). Then measure the diameter of the axle, which should match the hole in the bearings. For the tire, look on the tire and match that (4.00/4.80-8 for this one) or measure the total diameter of the rubber tire (15.5" for this one) and match that with the product details.This wheel takes a 3/4" axle and has a 3" hub. Standard sizes for axles are 5/8", 3/4" and 1". Hubs are usually 3", 4" or 6". If you can't find an exact fit, try to match the axle (bearing) size first, then the hub size. Bearings are harder to replace than adding plastic spacers to match the hub. If you can't find an exact fit, call Marathon for adapters. The bearings are harder to replace - you need to hammer the old ones out using a screwdriver (or piece of strong wood) through the center hole from the other size, then press or hammer in the new ones.My 1" rings from Marathon were NOT bearings - just metal pieces that were VERY hard to hammer in. But I finally got them. Then I added a plastic ring on the axle on each side of the wheel, and it fit perfectly. I had to remove the grease fitting to get them in, but added plenty of grease inside the wheel hub before putting it on the wheelbarrow.Do NOT get a wheel with too large a hub - you can only add length with adapters, not take it away!The tire says 4.00/4.80-8, 4-ply nylon and 30 psi max, but no load bearing. It looks just like this tire:  Marathon Industries 20801 8-Inch 4-Ply Rubber Replacement Tube and Tire  which is only 350 lbs rated, which is the only replacement tire I could find from Marathon so I suspect it's the same tire. Anyway, it seems sturdy enough, just not quite as heavy duty as the original tire which was 400 lbs rated.Also consider adding  Slime Tubeless Tire Sealant  in your tube if you use your wheelbarrow in challenging conditions. We have cacti so for us this is a necessity.

Good deal good price

I purchased two of these wheels to replace the old wheels on my Sears Craftman dump wagon. These Marathon wheels are well made and incredibly priced so they easily earned five stars. These are solid replacements at a price that's significantly lower on Amazon than you will find at Lowes or Home Depot, even for the same product. The wheels arrived fully inflated and they have a grease fitting making it easy to lubricate the ball barings. Unfortunately the wheels arrive with no spacers or dust caps. The dust caps on my old wheels did not fit on the new ones and it seemed that there was more axel play on one wheel which would be corrected by a larger spacer. I called Marathon and asked if I could buy dust caps and some spacers and they immediately offered to send them to me for free. Marathon is a company that treats their consumers well and truly provides great support and service!!! One last thing to note, make sure you measure the width of the axel before you buy wheels. These wheels are for 3/4 inch axels so if yours is 5/8 of an inch they will not fit.

Pros: I bought these for my Craftsman Pull Cart. Fit perfectly. Put on in 2 minutes. So far no flats.Cons: If you don't PACK this thing FULL of grease, the bearings WILL fall out. I mean FULL of grease too, not a few shots. It comes with NO GREASE. These wheels should have sealed bearings anyway.Other than the grease issue, they work great.

I paid $14.95 the next closes one I could find was $59.00 this tire has a grease fitting for the ball bearings that the more expensive one didn't, very happy with this purchase, I bought 3 more so I have them for replacements on the other older tires.

I had a blowout on my lawn cart and dreaded having to deal with a replacement since small tires are a pain in the butt.(Scroll to the bottom for simple directions to finding the item you need.)I did a quick search on Amazon and found these complete with wheels, tubes, and tires. Installation literally took 2 minutes. Wheels were even complete with grease fittings. Wheels fit perfectly and I didn't have to struggle removing the old tires and tubes using pry bars or screwdrivers.Most small tires and tubes have been made overseas for years and these are no different, but you will not find competitive products in this range.Simply look on the side of the tire for sizing information from your existing tire. Next measure the axle diameter (or the size of the hole in the wheel hub). Finally measure the length of the hub. You can insert a pen, rod, etc and then remove it and measure if the hub is less wide than the wheel. It can also be useful to measure the overall diameter of the tire. If its not inflated, you can estimate this.You should now be able to search and find the correct tire assembly you need.

Bought two of these for my dual wheel, wheel barrow. worked as expected, however be very careful that you get the correct axle hole size. I ended up having to build a new axle for my barrow to make them work (used heavy duty zinc plated steel tube). Cut it to length, drilled holes in each end to accommodate cotter pins, and everything worked great. About an 1.5 hrs to complete including running to Home Depot for the zinc tubing. Also, make sure that you grease the axle bearings heavily on the new wheels as they have no grease in them when you receive them.

I bought the tire because my old one went flat. I normally would just add a tube but I decided to try a new wheel and see how long it lasted. It lasted about a year before it started to lose air. So I would recommend that you buy a gallon of slime and solve your problem that way. All these tubeless tires seem to leak. So if you have a lawnmower and cart and wheelbarrow and handcart you will be spending more on tires over the years than the cost of the Slime.
