The age old what determines a commuter tyre or a race tyre...
Puncture resistance/Hard wearing/price for commuter? Rolling resistance/speed/grip/price for race?
For me a 'commuter tyre' is too broad a term. Personally my mileage would have to probably be over 6000 miles a year before I would be wearing tyres out quick enough to consider buying tyres (& wheels!) specifically for commuting. Until then a good combo tyre (Mitch Pro4E) is fast enough, cheap enough (<£25) and has enough puncture resitance to fulfil all roles. When a Conti 4000sii is getting towards the same price range it can easily be a premium replacement. The GP 4Seasons are a superb tyre, but they don't offer me much over the Specialized Roubaix Pro in grip/wet weather/winter to consider them, unless they're closer to the £22 I can get the Roubaix for!
Yeah thought that was the case when I looked, 'save' by getting a GP4000sii for £25, then pay £7+ for delivery (and wait for a week or more delivery if Rose are any comparison), when they're
£30 on Wiggle anyway with free 3-4 day delivery. Wiggle even doing a 'save 5% when you order 2. Dammit I only need one!
I picked one up new/unused with damaged packaging from the Wiggle 'bay page for £24 (+£3 postage which I offset by ordering several things from them the same time...)
I'm after something like a Nobby Nic in 700C for my Diverge, I've seen Continental Cyclecross Race/Speed/X-Cross but they only seem to be 35mm or wider, Ideally I'm after a 32mm for the front and a 30mm for the rear and I'm fairly sure they'll then go under my guards...! Any suggestions anyone?
TLDR; Most of the well regarded 700C nobbly tyres don't come smaller than 35mm (or 32mm). Alternatives?
If they're the Giant PR2 wheels then the freehub will quieten down but well worth your LBS checking out in 6 months or so, my LBS found that the pawls had come barely greased and a spring had broken within 6 weeks. Greased and replaced and they sounded much better (and continued to make the same noise not get louder/quieter). I replaced them with Compag Khamsim's as I had terrible problems with the Giant wheels just not staying true, got tired of taking them back to the LBS. Campag freehubs are a much better noise!
