Riding hardtail with spank 295 rim...Have tried 3 tyres now and keep losing, burping,pressure when riding....ardent tubeless ready, minion dhr2 tubeless ready and Goma rear tyres .. riding ragley mmmbop hardtail and just cant seem to keep tyre inflated when hitting rocky terrain,ok otherwise....is 295 rim the wrong rear rim for the job....? Have fitted On One cushcore and has got me home ok but still losing pressure....short of innerrube not sure where to go on this...any help much appreciated......
What width of tire, and what pressure are you running? If you're running a wide tire at low pressure on that rim I would expect trouble. If I remember correctly a 295 is 24mm internal width. That's pretty appropriate for a 2.3 or less XC tire, but a little narrow for anything bigger.
