[Closed] Plus or normal tyres on 'average' rims

[#8111118]

A couple of older threads pop up with Alex and scotroutes who were playing with different rim/tyre widths on this subject, but wondered how folk are approaching things.
I currently run 2.3 tyres on 19mm wide rims, so get the bigger tyres = more cush and rolling on rough stuff.
However, the reports of plus tyres being iffy in mud and higher resistance on the road/smooth, make me wonder if 2.1-2.3ish tyres work OK on average size (20-30mm) rims for winter, with same rims able to run 2.8-3.0 tyres in summer.
Or, is it not worth the faff and just run plus tyres all the time?
Or, is plus a fad and in a few years time we're all back to running 25-30mm rims and 2.2-2.8 tyres depending on season....

Make the switch to wider rims

I run + 29 & B on 2 bikes (~40mm int )

I have an 'old' (2012) high end FS - it has 2.3 (29) tyres. They look so small and there's no way I would them on a small rim (Stans Flow - obsolete now)

Go +

Ridiculously different

I'm eying up new bikes that vary from 'traditional' 20mm rims and clearance for a 2.3 to Semi Chub (28mm rims but still 2.4ish clearance) to full plus with boost on 40mm rims... I'm trying to work out if I can keep some flexibility should I change mind or a plus fad dues down...

A frame with clearance for wider tyres will obviously fit narrower ones so will be more future-proofed if Plus doesn't catch on.

Then it comes down to hub/chainline standards, to Boost or not to Boost.I reckon that's still a hard call. If you want to run 2x on wide (3") tyres then Boost is basically mandatory. However folk are still squeezing 2.8" tyres on narrower rims into non-Boost frames and getting away with it.

I'd opt for B+ / 29er again if I was looking at a new custom hardtail for bikepacking but would still be happy running 2.4" tyres in a Full-sus or playful hardtail.

Of course if Boost becomes the long-term standard then you might feel restricted in future but other sized hubs will be around for a looooong time.

I got rid of my fs recently as I was using my hardtail more and more.
Finally settled on a ti hardtail with the option of swapping wheels from 29 to 650 plus.
My 650 plus wheels I am thinking 40mm rims.
Its gonna be 148 Boost as well.

@scotroutes

That sums up my thoughts. I'm trying to work out if there is an affordable (@£1k) hardtail that can offer plenty of future proof options for me. There are not many....

Does Boost at the back move the drive side left wards to improve chainline?

Or do you need to go boost chainset/bb to achieve 2x clearance with 3"?

Yes. It seems to be that you can just about get away with non-Boost cranks if you're happy with 1x (and may actually have a better chainline with std cranks/Boost hub).

You wouldn't believe that 3mm could make such a difference but it appears to!

The Marins are on the list....
As is Sonder Transmitter for full plus/boost.
As is Pinnacle Iroko as half-hearted, but widish rims and lots of clearance.

My LBS(Dartmoor cycles) has one of those Marin's ex demo for about £550 I think. 17" from memory.
