I ran a 2.8 Rocket Ron on the back of a Sonder Transmitter in the Peak for a couple of weeks. It was light, relatively voluminous and fast, but the sidewalls were made of tissue paper, which meant that one the one hand they felt like balloons because you had to run slightly higher pressures to stop them feeling sloppy and, on the other, they flatted about five times a ride. I don’t know if the 3.0 is any better, but I kind of doubt it. They might be fine somewhere smooth and grassy – South Downs or similar – but horrible on even moderately rocky stuff at normal speeds.
Tbh, I don’t think plus-sized and light weight play well together generally because inevitably the sidewalls tend to get thin, fragile and lacking in support.
