Some interesting legal notes from Pirelli: Legal notes 1. ~20% Rolling Resistance reduction vs a non-ELECT™ tire.

Very interesting... me too I had got repaired one rim here in Italy... during the three days of the repair, I made substitued the 21" wheel with the same of my winter set of tyres, which was 19" (!)... do you think that it was a bad decision?
