[Closed] 29er Rim/wheel choices? [Also: rim width effect on tyre width?]

My rear wheel is on the way out... [sigh]

Will likely buy a whole new wheel (or wheelset) and then get it rebuilt as having spares is never a bad thing, especially when it comes to hardtails and rear wheels!

Old rim is the old Stan's flow EX, with 26mm internal width.  Width seemed fine for 2.3 - 2.5 tyres.

How much would going to an internal width of 30mm from 25.5mm make to the profile of the tyre?

Ideally I want about the same internal width, all black with removable decals.

If available I would have just bought the same again, but looks like the Flow is now 30mm internal.

Hubs need to fit 15x100 (ie non-boost) up front and 135QR at the back

I also need them by the weekend...

Options:

<span style="text-decoration: underline;">Hope Tech Enduro £225 for rear only</span>

Pro: Off the shelf at the likes of Wiggle/CRC, Hope hubs are a known quantity

Con: I think the rims are laser etched rather which annoys me slightly. Slightly narrower

<span style="text-decoration: underline;">Superstar Electro Alpine Trail Wheelset £250 for front and rear</span>

Pro: Cheap. quick? Choice of 24mm internal or 30mm internal rims

Con: Questionable build quality?

Anything else I should consider?

The biggest issue I'm having is that most rear wheels are thru axle and it's not clear if adaptors for QR are included or even available...
