Continental 4 Seasons - which size

edited June 2016 in Commuting chat
After much deliberation on my part, I've decided to put some Continental 4 Seasons tyres on my Giant Defy 0. Question is: what size do I go for? 25c or 28c? I hear these tyres come out a bit on the narrow side.

I don't really know what I'm doing here (the defy is my first 'proper' bike and I've not even got it yet) so any advice would be very much appreciated.

    On 21mm rims they come out wide enough.

    I swapped 25mm for 28mm on my CX this winter and it felt slower. Caveat; I am currently slower.

    So you'd advise that I go for the 25?

    I run 19mm rim width with 28mm Conti GP4season and they measure 28mm on the bike. I like them - ride nicely and relatively few visits. Durano Plus are nice as well - and there is a now 28mm for the Durano DD

    Yeah. I've used 25mm 4Seasons for years. Trying 28mm was an experiment and I'm not going to do it again.

    25s ftw.
  • I read everywhere on the 'net that Four Seasons is the best tyre there is! My impression is Four Seasons gets more love than Grand Theft Auto Five!! Seriously!! Four Season is the God of all tyres!

    That's because the net archives everything for ever. Durano Pro are the new Four Season. Same handling and rolling resistance, better puncture resistance and more durable. The Four Season's Achilles heel is its sidewalls, particularly next to the the bead where it's abraded by the rim. The vast majority of my 4 Seasons died due to a catastrophic failure at this point. I'd recommend the 25mm Durano Pro.

    They're the best tyres ever until you ride the Michelin Pro4 Endurance, which really are.

    And I was a victim of the 4 Seasons sidewall failure - in the middle of nowhere in Portugal, had to tear up a censored packet found by the side of the road to provide enough support inside the tyre to be able to reinflate the new tube and get back to base.

    I've read a few articles / posts where the 28mm GP4S measured less than 27mm on a normal, narrow rim. My 25s measure 26, so I'd suggest those. I've been running 25mm GP4S on the winter bike for 9 years and not had any sidewall failures, but they don't look particularly robust there I have to say. First set I wore right down to the carcass and still no punctures.

    Downside is the price which has become a bit silly now, so I'm going to try the Michelin Pro4 Endurance when this set wears out.

    25s GP4S on my winter bike, wider would make clearances for mudguards and the frame rather too tight.

    I've been a long time GP4S fan (25s) and have recently tried Pro 4SC and Durano Plus. I have to say I've not been that impressed with either. The Pro 4s look as if they'll last forever but just feel a bit uninspiring. The Duranos just feel censored .

    I think I'll be going back to the GP4S. They may not last as long but I'm not spending every ride wishing they'd wear out quicker so I can replace them!

    I'm currently experimenting with Panaracer RaceD Evo 2s on the Genesis, GP4Ss on the Canyon and Durano Plus in the SS.

    GP4S did not last for me; it cut up Much faster than previous Fortezza All Weather on the same commutes and eventually blew out after checking for major cuts that very morning. Size probably depends on your commute surface, and for longer weekend rides on nice tarmac 28 mil would, probably, be a bit of a wasted effort.
