Mboy, The rims are the off the peg ones on the Zesty 514, Shimano XT WHM778. Was running them at about 25-30 psi, I’m 9st.
TRUST me on this, try upping the pressures a bit. Say 5psi either end to start, see how that goes, then perhaps try a bit more even…
These tyres require more pressure to work well than I’m used to, but once I upped the pressure a bit I was very impressed! They’re my default race tyre combo now as they’re soooooo quick yet grippy, and fairly tough to boot. And like I said I’m 12 stone, and not particularly easy on kit either. Definitely don’t work so well at lower pressures for sure though…
Houns, XT wheels and the Hutch tyres are both proper UST, a bit of sealant always helps though, and the Hutchinson tyres do have slightly thinner walls than say a Michelin UST tyre.
