I’m not against big tyres, I have a fatbike which is great fun, but I just couldn’t get on with plus tyres, I had some 27.5×3 on my ebike, so not sure if the extra bulk of everything had an effect but just couldn’t seem to find a tyre pressure I liked. Anything below 20psi and it felt like the tyre would come off the rim, more than that and it felt like I had solid tyres. That and they were garbage in any type of mud, just skating over the top. Changed to 29×2.35 and they were better, but could do with improvement, now on 2.5WT tyres and that seems like a sweet spot, so I guess I’ve settled on 2.4-2.6, with reasonably wide (24-30mm internal) rims.
A long way from trying to squeeze 2.1 tyres on 17mm rims into the back of my first bike, that’s for sure…
