Are Wider Rims Better?

I still remember the corner clearly. Dropping off the lift, you pick up the narrow, rocky trail down to the grass. Mud soon replaces rock underfoot and the tyres start biting. The corner itself is just a flat, grassy bend as you traverse from one side of the resort to the other. Leaning into that first corner something unexpected happened. As I started to lay the bike over the tyres held, digging into the dirt and I could push the bar closer and closer to the ground. That's the magic - one of those perfect moments when the bike and the trail seem made for each other, when you feel like a hero, if only for a split second.To get more news about Carbon rims, you can visit zpebicycle.com official website.
That was my first corner on wide rims. Nothing else in my setup changed - same bike, same tyres. My 25mm internal width wheels had been replaced by burly-looking Ibis 741s with a full 35mm internal width that my wife had left over from her race season.

Through the rest of the day, I giggled my way up and down the bike park in Roubion, pushing the bike in a little harder each time, trying to get closer to the limits of grip. For me that was it, I was sold. In fact, since that day in 2015, I have switched all my bikes over to wide profile rims. They felt good, so I haven't built a bike with rims less than 30mm wide since.
Wider rims better support the tire s side wall.
Syntace's graphic depicting the wider rim's stabilizing effect upon the tire profile holds the record for the most poached image on the subject.

There's one problem with this: it was a flawed decision. If I'm honest, that decision was almost entirely based on feelings from that single corner. Over the years since, I have covered a few thousand kilometers on 35mm rims, and I can confidently say that I like them when they are paired to the right tire (I have been running 2.35 Schwalbes pretty religiously). But, if you stopped me and asked why, I couldn't really give you a much better answer than how good they felt in that one corner.
Back in 2015, anything over 30mm was fairly extreme, but today it is generally accepted that wider rims are better. But, if we get down to the fine detail, how exactly does a 30mm or 35mm rim feel better than a 25mm rim? Aside from every manufacturer's press release claiming that their rim offers the perfect balance, what does it actually mean out on the trail? Is it better in every situation? Are there drawbacks? How wide is too wide? Or, did I just get carried away and I've been getting it wrong all along? To be sure, I had to separate my feelings from the facts, and the best method to accomplish that is a side-by-side comparison.
