I wonder how long 195/50 15s will last on a heavy old Commer? On my little hairdressers car, pot holes have claimed a good 4 or 5 of the same profile. The current Toyo Proxes seem to be holding out well, although for how much longer with the roads as diabolical as they are right now, I don't know. Will be interested to see how you get on as skinny rubber up front looks great.
