One of the important features we wanted was a tougher sidewall so we are using a double ply lay-up in the tyre carcass to stiffen up the tyre & improve impact protection. The dense tread pattern is fast rolling with a round profile that wraps bead to bead adding further protection to the sidewall. The tread height varies across the section giving loads of grip without &8216;squirm&8217; on hard surfaces like concrete & wooden ramps etc&44; the full wrap pattern gives grip in places other tyres fear to tread!
