Maxxis is the only company that bothered to make a big deal about it, but the same applies to almost every wide, modern tire. Any tire intended for wide rims has to have more tread wrap. Put a highly wrapped tire on a narrow rim and you'll never engage the side lugs. That's all there is to it. Not only are the lugs too far down the sidewalls, but a large tire with insufficient rim support will deflect under lateral load, making it even more difficult to engage the side lugs. The good news is that the tire will still work fairly well. The combination that doesn't work is minimally wrapped tread on super wide rims, as you'll lean beyond the lugs and onto the sidewall, instantly resulting in a crash.

If you want to run a wide tire on a narrow rim, ideal choices are tires with minimal tread wrap; decent choices are tires with staggered side lugs or intermediate lateral lugs. Examples include:

• WTB: Breakout 2.5", Trail Boss 2.4", Vigilante 2.5".
• e*thirteen: Anything from their previous generation in 2.35"
• Vittoria: Martello 2.35", Morsa 2.3", Mota 2.35"
• Goodyear: Newton 2.4", Newton ST 2.4"
• Hutchinson: Toro 2.35"
• Continental: Rubber Queen / Trail King 2.4" (previous version)
• Maxxis: Rekon 2.4", Forekaster 2.35", Minion SS 2.5"

What happens when mounting one of those WT Maxxis tyres on a 25mm (internal) width rim? My LBS says they're unusable and too rounded, however one of my mates who works as a shop mech says it's fine and won't make a difference. Anyone have an input either way?
The narrower rim is going to increase the sidewall height a bit and maybe make them squirm a bit more under hard riding
and you'll have a greater lean angle to hit the cornering knobs but definitely not "unstable".

Wouldn't surprise me. My other options instead of WT doubledown tyres are the SG Magic Mary, or the E13 DH tyres (which are on sale here, very tempted to try them out)

e*thirteen tires are perfect for narrow rims, especially the previous generation, which is probably what's on sale.

Thanks (as always) for the detailed response! Those e13's are looking better and better to me.

As they should be! They're super "square" or "flat" on wide rims, which is exactly what you need on your narrow rims. The photo below is with at 25 mm rim.

What lightweight options are available to replace an SX cassette?

I ordered a LG1 DH Plus for the rear and Race for the front, I guessed the dual ply DH would be similar to a SG/DD tyre.

If it has to be 12-speed and HG freehub, then Garbaruk make a 320g 11-52 cassette. Actually reasonably priced compared to a lightweight eagle cassette.

I'm not sure of all the construction details for the e*thirteen, but it's marketed as a full DH casing and the weight is on par with full DH tires from Maxxis and Schwalbe, so it should be burlier than a DoubleDown or Super Gravity.

Cheers I'll look that up. My rear wheel weights a ton, most of it being the cassette.

SX cassette weighs 615g - around the same as the NX


XTR 9100 is 370g


Garbaruk's 320g

A note that 320g Garbaruk is for Shimano HG body & second it can only be used for 12sp Shimano drivetrains.

This is massive difference. And a very good place to save weight. I'm thinking about Garbaruk when current GX wears out
