As suggested earlier in this thread, my thick rim wheel is not 13", it's actually smaller at 12.75".

It also has a dish depth of 1", this means the stalks are 1" further away from the rim than with my flat rim wheel and reduces the roof up entry gap to post my posterior through from 15.5" to 14.5", for those broad of beam like myself the reduced the gap between the steering wheel rim and the outer seat bolster can best be described as...... snug! blush

Until full removal I am unable to give you a direct depth comparison between my current Moto Lita B71 NB hub and the Optimill ORP37-48 that is set to replace it, but a quick comparison certainly suggests the quick release hub is at least 1" shorter. So, in theory my new quick release steering wheel hub should as a minimum return the rim to stalk clearance back to what it was, and open up the rim to seat bolster gap by the same amount too.

In theory, I should end up with all the benefits of the smaller diameter thick rim wheel, while resetting the other parameters back to where they were when I ran Monty's original 14" flat wheel. All this with the added benefit of being able to remove the wheel entirely, as such, I am ergonomically preparing Monty for the results of his owner's incurable addiction to doughnuts, and his advancing years!
