What rim width and pressures are you running?
Having set up my XC (well.. do every trail in Squamish bike) on 20mm inner width Tricon 1550, no rim tape with 2.4 Mountain King II front and 2.4 X-King at 22+psi.. i determined that insufficient pressure and too narrow a rim for a tyre of that volume was never going to work.
Interestingly (to me) the Mountain King II 2.4 RTR on EX1750’s with DT’s rim tape at 20psi are faultless.. so.. rim with and volume being taken up by tape inside the rim is key.
I’ve reset my front at 28pi (still no tape) and no burps so far.. but pushed harder I fully expect to leverage the bead away from the rim at some point!
Rear had a tube in for yesterdays loonie race in Squamish.. but pinch flatted so damned if I do, damned if I dont 🙁
So… interesting article here…
