The rim is not at fault. Some random sharp pointy object cut your tire. Find the hole. Patch it. Inflate. Ride and enjoy. 819's are great hoops.

Edit: Kenda Navigator? Is this a new tire? I can't find any information regarding it.

819's are plenty strong for your weight.....you simply cut your tire on something. Sh!t happens.....replace the tire and get back out there! :)

Sealant is a UST tire....

is a matter of choice. A UST tire will hold air just fine without sealant. But, as you've just discovered, there can be a need for it. You can still get punctures in UST tires. For the most part sealant in a UST tire is just good insurance. In your case however the pucture or cut was just too large for the sealant to handle. So your choice on that one. Where I live we don't run tires, tubeless or tubed, without some sort of sealant. At certain times of the year we've got thorns called "goat heads" that have 4 spikes on them arranged in such a way that when they fall to the groud there is always one spike sticking straight up. They'll puncture anything from a standard tire to a heavy duty dual ply down hill tire in a heart beat. So unless we want to walk, carry a half dozen tubes on every ride, or are just feeling lucky (read stupid!), sealant is used.

Your choice, but from the sound of it, a good tire sealant would be a good idea for you.

Good Dirt
