Yes, UST tyres are thicker and as a result, heavier, but they seem to grip when cornering better IMO. Don’t know why, maybe they stand up better under load?.. Interesting that there are so many differing opinions about this – given tubeless has been with us for some time, I guess it’s always going to divide opinion.
Must check my trail pack tube and pump still work – they’ve been buried in the bottom of the pack unused for three years now :-)
