Save yourself lots of aggravation and buy inner tubes for these particular tires. I bought 2 Greenball ribbed tread tires 480/400-8 for my lawn cart. They are good tires, but the bead edge of the tires refuses to seal airtight to the rims of the wheel barrow/lawn cart type rims. The rims were clean, straight, and in good condition. The reputable tire shop tried several times unsuccessfully to mount these as tubeless. They finally had to use inner tubes to get them to hold air. Apparently the shape of the molded bead is not exactly right for the intended wheel barrow/ lawn cart type rims. I've used Greenball tires of other sizes on several mowers and had no such problem. It seems to happen only with this particular tire size.

Bought 2. They come flattened out and shrink-wrapped. One resumed a tire shape and could be mounted/inflated onto rim. The other stayed so twisted that I had to go out and purchase a tube to install just to shape the tire to reach the rim in order to inflate. Had to leave the tube inside the tire.

It is a tire that you mount on a rim and then air it up IF you have a valve stem on your wheel! There is no tube in it. It will eventually go flat like any tire with a tube when you run over stickers. From the description I thought it was a solid rubber tire that you mount somehow on a rim. Returned it.

Not the best tire I have ever seen, but good enough. Great price.

I sent them back got them cheaper from Amazon with tubes

Shows a metal rim plus the tire, very misleading!

Great value. A little hard to get it to take air.

nice tires, price is also nice. and they came fast.

Good Price - Great Service

Much better quaility than I expected for the price. I would buy them again
