bought because wheelbarrow with two wheels had tubeless tire leaks in sun and bad weather for more than 10 years. The tire leaked under the tread and lost air within a day. The main annoyances to be filled in before using, esp. in bad weather. I ordered the size by sidewall numbers, chose cheapest shipping and it arrived 1 day earlier than expected. Relax. The assembly turned out to be a bit more difficult than expected, possibly due to the fact that the tire is tubeless. I managed to get the tube far into the body and had to use screwdrivers to get it back onto the rim. BE CAREFUL ! A screwdriver can easily pierce the tube. I succeeded and after a few days I found that it was still holding air. Much luck!
