I got to the tire yard with another functional fitness enthusiast and the first tire I tried was way to heavy. I flipped it, but it had to weigh over 400#. This one felt pretty good and is probably on the order of 250#.
It felt as good at home as it did at the tire yard. I will probably give it a bit of a scrub down and drill some holes to prevent water from accumulating in it.
UPDATE: 5/11/2021. I used this a lot less than I planned on and ended up parting with it on Facebook Marketplace.
