Remind me, is it better to have softer rubber on the front than the back, and never the other way around, yes? Got a plan for tomorrow to get a new front qualifier II for the 10R, and at the same time cascade the half worn one down onto the ZRX to replace the absolutely knackered front azaro. I know mixing tyres isn't the cleverest thing to do, but given the ZRX is a stable old bus a sticky front should be good for the rest of the year, I'd have thought. Opinions?
