3000 miles in two weeks and my rear (new) tyre is square... i was expecting it given the motorway distance but it's now ready to change.... does having full luggage and two up wear the tyre much heavier?
When i get round to it i'll post some pics on the bike in the Alps etc
Stay off the motorways, and find some bends :-D Shouldn't be too hard in France I usually go to Spain (via France), and don't have a problem with square tyres!
I have 6K on my michelin pilot roads and have done some two-up riding with luggage. all riding has been in long, flat, straight, Florida so the side tread is virtually unused. nevertheless there is some squaring but not a whole lot to make the ride uncomfortable and there is plenty of tread left.
