Tyre Choice/Upgrade From Michelin World Tour 32c

Ive got a Dawes galaxy with Michelin World Tour 700x32c tyres, I was wandering whether I would feel a difference in speed and rolling resistance if I upgraded to race type 28c tyres, and whether its as easy as swapping them, (whether theyll fit the same rims).

Im thinking of getting some Continental Grand Prix 4 Season tyres in 700x28c size, I know that itll probably be a harsher ride, with the narrower tyres, but interested to hear what people think, whether its worth the money in changing or not, they would cost 64, about $105.

How wide is the inside of your rims? If 19mm or less you'll be easily able to run 28mms. As for the ride, at 80% of maximum pressure (assuming unloaded) you might notice a slight difference in ride roughness and better acceleration. But not enough that I would replace a perfectly good set of tires.

For touring, I go for puncture resistance first. The time it takes to fix a flat can neutralize any small speed advantage you'd get from a "racing" tire. And a long day in the saddle is less tiring on a tire big enough to smooth out the road a bit.

In other words, spend your money on something more useful than a smaller, lighter tire.
