wheelset says 30-46 mm What can go wrong?

Hi, descrition of my Fulcrum gravel wheelset says "The profile of the wheel enables tubeless ready tyres of between 30 and 46 mm" I have a pair of 650B 2.2" tyres What can go wrong? should I stick to specification?

Do you have clearance within the frame for the full range? What’s 2.2” in new money? Also are the wheels 650B?

If so, not sure what could go wrong other than to bear in mind some tyres come up a bit bigger than the size stated when inflated, so sticking to 42 or less could be preferable.

why not just try to fit the tyres and wheels and see?

Hi, Yes plenty of clearance in the frane, Wheels and Tyres are 650B. Not sure why the wheel manufacturer recomend those specific tyre sizes. I'm just worry something will go wrong maybe the tyre will get out off the rim or something. I'm not sure that's why I'm asking

Just get the correct sized tyres if concerned. 2.2" is a fair bit fatter than 46mm...you may not even be able to get them to seat in the rim with an inflated tube, so you'll know it won't work before trying to ride the bike

2.2 would be around 50c so not much difference. You've already got the tyres so give it a go. Are you intending running them tubeless?

the wheels will be fine with those tyres.......

Personally I'd not want to risk a tyre coming off the rim going into a corner and potentially locking up the front wheel.

You'd certainly have no come back if you've knowingly fitted a tyre wider than recommended.

57mm approx

57mm approx

So quite a bit more than 46 🤷‍♀️

Google says 55.88mm so yeah. A fair bit more than 46.
