Are the hubs the same for demountable/non demountable/30X3/30X3.5?
If not are what are the changes?

The front hubs differs over the years, generally early brass era hubs were weaker, so if you're building a speedster type of car, a 1916-27 hub would be better, cheaper and easier to find. By 1919 when the demountable wheels (and the Timken roller bearings) were introduced all were alike, whether in a demountable or a non demountable wheel, but the non demountables got ball bearings for some years - though they are interchangeable.

The rear hubs were quite alike after the tapered axle was introduced 1911.

My plan is to run demountables 30X3's on the front and 30X3.5's on the rear employing good hubs and new rims. I figure its just going to be safer and easier than trying to find/repair original rims. From there I will have them respoked. As I need to source hubs I was wondering if there would be any problem using later hubs in earlier non demountable wheels.

I wonder if there were any demountable 30x3" wheels? All demountables from Ford were 30x3.5" all around.

I wonder why Ford made the change? Those ball bearings are huge by todays standards. I also wonder how Ford kept hubs separate for non starter/starter cars?

In getting new front wheels for my 1915, I cheated and used 1917-1918 hubs. They still have the machined flange and holes for a speedometer gear, but are more substantial than the earlier hubs so I could add notches for removing Timken bearings. So yes, front hubs introduced in 1919 along with with demountable rims are sturdier than 1916 and earlier, have removal notches, and have no speedometer features..

Roger,
To the best of my knowledge there were no demountable 30x3 rims on any car make, either as original equipment or aftermarket. I would suspect that there was no advantage for any company to make 30x3 demountables when the car could be equipped with 30x3 1/2. By the late teens only 5 companies used 30x3 on their cars, 4 were very small producers leaving the only large one Ford.

My observations: Ford used ball bearings initially, however because of lack of maintenance, felts and bearing grease, they were prone to early failure and the inferior ball bearings were to blame. The jobbers and after market crews introduced the far superior roller bearings, however they were too wide for the housings and stuck out board by about 1/8". Some of the hub makers decided to aid the market by introducing a modified hub by extending the hub material to fully enclose the new roller bearing. The first extended hubs were very thin and prone to cracking and the wheel bearing issues continued. After some time the hub makers further modified the hubs to accommodate the roller bearings with all the parts inside. Some hubs have recesses to remove the bearings and some don't
