Is it possible to change from road tyres to commuter tyres on a 2014 Giant Defy? Thanks

    Changing tires is relatively easy, so long as the size of the new tires suits the existing rim and frame clearance. Jan 7, 2019 at 3:23
  • Question title needs an update, its about tyres not wheels

That model of Giant Defy will have clearance for almost any 700×28 tyres and some 700×30 models, but not all. If you are after a commuter tyre for increased puncture resistance, a Schwalbe Durano plus in 700×28 will be as good as any of the wider commuter tyres and will perform just as well on any sealed surfaces. If you want to ride a bigger tyre for better grip on gravel and unsealed roads, then your options are very limited.

    Short of MTB trails or roads surfaced with loose broken stone you can ride pretty much any road or bike path on 28s. If it is a little rough I'd want something a bit tougher as well as a little more grip - but only something like marathon plus. Even with 28s you'll struggle to get mudguards in there, and they're good to have commuting in imperfect conditions

  • I'll note that 28s can be a bit iffy on the rear wheel if you're loading up the rear panniers on that road bike commuter with 10-15 kg or 20-30 lbs of stuff. If you're going to load a bike like that, you really do need larger tires, especially on the rear. Jan 7, 2019 at 10:53

    @AndrewHenle That depends how much you weigh ;) I could load 20kg extra over the rear wheel and it wouldn't be any different to a larger bloke riding the bike unloaded.

  • @AndrewHenle I run marathon plus 28 on the back of a hybrid with a ~20kg passenger in a ~3kg seat, and I'm over 80kg myself. You've got to pump them up quite hard though. It looks like durano are rated to a high enough pressure as well.

  • @ChrisH And you're real careful that you don't hit pavement edges square on at speed with that, aren't you? ;-) Jan 7, 2019 at 14:12
