Max Width of Tyre for a Mavic Cosmic Carbon wheel 2014 model

[rastapasta]

Morning

A simple one, whats the widest I can go as regards to a road tyre on the above wheel, does any one know?? I am looking at continental Gaterskins and i have the option of 25mm (which Im sure will work) 28mm (not so sure) 32mm (even less sure).

Many thanks in advance

28's wont be a problem, but I doubt 32's would work.

You may also have clearance problems with your frame depending on what you're riding?

Thanks Chris. I am running 25mm currently. The CX bike has 32mm so i guess you are correct regarding the width. Comes down then to the 28mm and whether they would be too wide or not. I think i would get away with it as regards to clearance. The bike in the photo is a supersix evo and I think the clearance is sufficient. Do they 28mm make much of a difference over the 25mm in terms of grip/cornering/confidence

I would say the main difference when going wider is that you can run at lower PSI, which in turn means increased comfort and grip/contact patch in colder/slipperier conditions.

I can't see the photo (blame work filters) but I have a Supersix and not 100% convinced the 28's would fit, especially around the rear chainstay/BB area?

I wouldn't go any bigger than 25mm tbh. 2014 Mavics have very narrow rims so 25mm will likely look a bit bulbous. I'd also reconsider the gatorskins, they don't have a great reputation for grip - what sort of riding are you doing?

Firstly - don't get Gatorskins, horrible tyres.

Conti GP 4 Season is a much better option, pretty much the same puncture resistance but a much nicer compound than Gatorslips.

2014 Cosmics will be the old narrow rim so going wide beyond a point is not that worth it, you'll just end up with bulbous tyres, prob 25mm max.

Hi thanks for this. Mostly alpine. Live in central Switzerland. The commute to work for example involves going over a small alpine pass so only need the tyres for the summer. I was looking for the wider tyres to inspire more confidence going downhill but i guess if they wont work I'll stick to the 4 seasons currently on her.

yeah theres a risk of making a balls of it. Maybe I'll stick with what I have for now. thanks for the input though. How do you like your supersix?

The recommended maximum tyre size is based on the inner width (ETRTO). I would expect that particular rim to be 15mm, in which case you're OK up to a 32 mm tyre. Whether you have the frame clearance is another matter.
