I have always used avon Distanzas, an theres probably 80% o the xtx boys on here done the same.. they are a great tyre.. brilliant in teh dry an great in teh wet.. only thing is teh rear sqaures off to quick.. but overall a great tyre fur a season..if yer gettin 5k miles out yer seasons worth of a tyre.. its a cheap season really.. Im looking at TKC80`s the now.. ave had them before,, but not on a xtx,,, ive had them on teh R.... but like the look o them on teh X
