I'm running ust fire xc pro's for general riding as they suit local conditions but as I'm returning to do Mountain Mayhem again this year I'm contemplating something lighter / faster rolling for if it's dry (ps I do already have the more likely mud tyres :roll: ).

Looking at rocket rons but the ust one is around 200g heavier than the tubed you'd have a bit of sealant in aproaching half a kilo minus two inner tubes.

Am I better off going tubed for the the racce with lightweight tubes?

Also looking at furious fred which seem very light but are they a nightmare with that little tread?
