December 30, 200718 yr hi all im having problems getting a tubless tyre(pirelli) to seat on a tube type rim. im using plenty of soap on the tyre but about 6 inches of the tyre will not pop on any ideas cheers mick
December 30, 200718 yr Author iff thats the case why wont it just seat when i blow it up for the umteenth time
December 30, 200718 yr I remember overcoming this problem many years ago by grinding the lip (the sealing edge bit) off the tyre with an angle grinder! Seems a bit harsh, but worked a treat!
January 1, 200818 yr No, they are both the same size; 18" However, the tubeless tyre really has a slightly smaller inside diameter because of the sealing edge which the tubed tyre doesn't have. Therefore you can have problems getting a tubeless tyre to sit properly on a tubed rim as it's a tighter fit, in effect. Grinding the lip down on the tubeless tyre did work, but is a messy & awkward job.
January 1, 200818 yr You could try compressing the tyre by putting a ratchet tie-down round the centre of the tyre and tightening it up, then inflate the tyre with a compressor, a foot pump will not input the air fast enough to pop the last bit of bead.
January 1, 200818 yr nothing on a tubed rim to pop onto as stated before. But the tyre can still sit squarely on the rim, or not as the case may be.
