Alexrims EX30

[Beekeeper]

I have Alexrims EX30 on my Cube.

The bike came with 29 x 2.6 tyres so what other width tyres would fit on these rims?
What would be lowest and highest width tyres I could use?

assuming the 30 stands for 30mm internal rim width you could run anything from a 2.3 to a 3.0 tyre.(in actual fact a 2.0 would work just fine too). The only thing to take into account is a narrower tyre will have a shallower flatter tread profile while a fatter tyre will end up more rounded. being a more rounded profile it'll need slightly higher pressure to maintain sidewall stiffness/support.
There's far too much hype over rim widths and tyre volumes.
it's not long ago 21mm rims and 2.3-2.5 tyres were what almost every WC DH rider ran but now all of a sudden folk are worrying about what rim width and tyre volume they need to ride local XC or trail centres.
Marketing clearly works though

Keep in mind this is information from a man who's been riding so long that bikes had square wheels when he started out .. and rim width was a way of measuring the physical discomfort you went through from sitting on a sharp log ...

My mtb riding actually pre-dates the "huck to flat" years bro A time when shit 3.0 Gazzalodi tyres on square wheels became a fairly common sight among the raddest mtb circles.
