I made the switch from riding 2.1s to plus size tires 2 years ago and it has been a great switch. The stability provided by wide rims and tires has made a huge impact on my confidence and ride quality.
I started out on WTB ranger 3.0s. It’s a fairly low profile tire, light and it rolled well even for a 3.0. Unfortunately the tread wore very fast and I agree 3.0 is wider than needed.
Next I went for the Maxxis Rekon 2.8. I think it’s a good tweaner, knobs aren’t crazy but have some bite. I bought the silk shield version which I think is overkill. The things are bomb proof but add about 100 gs and I never blow sidewalls either. I’m interested in going back to a lower profile knob like the Ikon but worry how it will hold up in super loose conditions like front range Colorado. Going to try normal Rekon+ first.
Tires are the toughest part of the bike to pick but have a huge impact. You are always balancing grip, weight, and durability. Luckily we have endless options to choose from these days.
