25mm v 28mm Tyre

chopchopchop

I had a few problems with my rear wheel when I got my bike so I put 28mm Schwalbe Marathon on them. It's very comfy with them on but will I see a noticeable difference going back to the 25mm tyres that came with the bike?

You will notice a drop in average speed apparently 8)

But seriously, just give them a try and see what you think.

Wider tyres are more comfortable and grip better; and if you buy sensibly they're barely heavier.

Use what you prefer. I like both.

I run Schalwbe 28mm Marathons on one bike and 25mm Mavics on my other bike.

The main difference, seems to be a better level of comfort on the 28s, and a better ability to soak up road imperfections (aka small holes!).

The 28 equipped bike is a CX, and the 25 equipped one is a pure road bike, which weighs less. On club rides (60-80 miles and 3-4000ft of climb) both are fine, and my overall average speed is not noticeably affected by the tyres.

Drummer boy, you are obviously not measuring properly. Everybody knows that thinner tyres are faster!!

28mm Schwalbe Marathon are not the quickest 28mm

Do a time trial loop with both sets.

Fully agree with this, but they are my multi-surface tyre of choice for wintertime, when my commute is half tow path, half tarmac. Pretty puncture resistant, and hard wearing. The pair I have on now have done 2000miles since last Xmas, with only 2 punctures, and one of the was a Chuck Norris nail!!

Quite right, but not as fast as a 25mm tyre on a red bike. Everyone knows red bikes are quicker as well.

My bike with 23mm tyres is 1 second slower than my bike with 25mm tyres on a 10 mile TT, so I will be using 25mm in future.
The bikes are completely different, the wheels are completely different, the frame & fork materials are completely different, the times were set 2 weeks apart in different weather conditions.
That's about as scientific as most of the opinions on this subject.
