Is there anything to be gained....

From switching 25mm tyres to 23mm on a hybride bike.
I cycle 20mile commute most days.
I woke this morning to find my back tyre has a huge bulge in it, so do i just replace like for like or get the 23mm, what are the pro and cons, or is there any?

cheers

You can get a Marathon Plus in 25mm, prob the best commuting tyre. Otherwise, blindfold me and I couldn't tell a 23mm from a 25mm

25 is slightly more comfortable perhaps, more surface area for grip in winter. Heavier, if you care about such things.

If you're going to run different tyres stick the fatter one on the back.

Which is more important for you on your commute? Improved aerodynamics or decreased rolling resistance.

Don't you know how competitive commuter races have become? People on TT bikes and aero helmets, that increased rolling resistance of a 23mm tire could mean you'll get to the red light 100 metres down the road before the other guy.

It has generally been assumed for a long time that narrower tyres run at higher pressure roll faster, but in recent years various studies (and some manufacturers such as Zipp) have challenged that view. Many people now believe that, within reason, lower pressure tyres roll faster and that wider tyres do too. There are some threads on here within the last few months where this was discussed and links to various articles and studies posted.

In your shoes I'd got with 25mm tyres, and use a tyre pressure based on your (and the bike's) weight. I'd guess that you'll lose nothing in terms of speed - you might even find it a bit faster, but whatever else you should find it more grippy.

I stuck my spare wheels on the commuter machine today and they have 25mm tyres (as opposed to the 23mm that I'm used to). God dam I never realized the N81 was such a smooth road. Felt fantastic

That's why I ask.

Right lads, I checked why my tyre had a bulge in it and it turns out there were 3 bulges in it! On the inside the nylone fabric had split/shredded.

They are kendel tyres which came with the bike and had about 2000km on them.

One other cause is the other half went out on it for a "try".

That's not the first "Kenda tyres are crap" story I've read.

Yeah guy in cycleways said they (Giant) just put then on so they can wheel the bike out off the factory floor.

Maybe 2000km isn't bad for a tyre that costs about €9
