I’ve got a set of the hauuge Liteskin 2.35 by 29s on my steel inbred 29er which I use for road rides and exploratory duties, well I did in the summer at least.
Lots of single track roads and fire road/estate tracks around here.
On the road at 50 – 60 psi they roll along nicely on the third world roads we were left with after last winter.
Find some offroad, drop pressure a bit, and they are great with the big volume.
Clearly they are rubbish on grass/mud but on fire roads at 30ish psi they are faster than just about anything else out there. 🙂
As others have said, they can do weird things to the handling, on tarmac they want to make the front end on my inbred want to flop over into turns at low speed, and at high speed it needs to be muscled into urns due to the gyroscopic effect from their weight.
I like them, they look cool too with their big balloonyness.
