I just returned from a 2 day ride which ended in a lot of night rain. I could not keep the rain from obstructing the view and it became quite unsafe to ride. I had to take side roads instead of the super slab and even then I had to strain through the top of the visor with it partially open so...
I live in Canada and find that the price of my favourite tires, the Metzler Roadtec Z6s, are great but pricey, closing on $800 Cdn including mounting costs of $50 Cdn per rim.
Can i get away with NOT replacing the front tire every other time when I'm changing the rear, every 20,000km or so...
