Anyone know anything about the Continental Contact CH90, CH95 (Conti Touring) and CH90 RF? They are rated 'high performance' by Tire Rack and are only $49, $55 and $58 each, respectively. This is for the 5000TQW for daily street use. All above are H-rated. How about the Firestone Firehawk SH30, GTA, GTA 02 or GTA at $59, $53, $50 and $49 respectively? TIA, -glen
