Hello to everybody, I'm new to trials and I just bought a TXT pro 280 05 and I changed both tyres for fresh brand new xlights. I have no problems with the rear but the front tyre if I run it at 0.5-0.45bar of pressure it just comes off the bead and goes inside the rim for about 15-20cm. If I put some soapy water and pump it up to 4bar it pops on again, so I leave it for a day to set in place but after a couple of rides it goes off again. I did clean the rim etc. Any ideas? Thanks
