I was looking for some rims for my 23 so I "borrowed" some from a 490 trailer. Unfortunately they did not fit because the valve stem was in a different location in respect to the 4 lugs.

I couldn't just drill a new hole for the valve stem as it ran conflict with a spoke.

One of the rims on the 23 had two valve stem holes and would fit both rims.
Are you sure that the wheels and rims are both Chevrolet? I have heard that Ford and Chevy look the same but don't interchange due to location of valve stem holes.
There is a 21" demountable rim that is easily confused between Chevy and Ford. The location of the valve stem is the issue. There are probably some wood spoked wheels that could have the hubs interchanged. This could lead to a confusing situation also. I have some 23" clinchers, I'll take a look.
Hi Mike & Chipper, Easy way to differentiate 1923 Chevy from Ford wheels: . (Exploded T ford wheel) . Ford has hub (2815) on the inside and plate (2827U) on outside. Chevy has plate inside and hub outside. On front wheels, Chevy has ND ball bearings. ford has roller bearings. . The tire size is 30 X 3½. (30 - 3½ twice = 23" rim. ) 1928 and maybe 27 used a 21" rim. 1929 used 20' rim car and truck. 1930 used 19'rim. . One never knows who put what on my car. Only the RF wheel has 2 valve stem holes. The trailer was made of a 1922 490 or a 1923 "B". I believe that 1922 was the first year 490 used 4 lugs vs 5 and it has a dipped axle. But, it has semi-eliptic springs that could be from a 1925 - 30 due to Alemite grease fittings. . . Thanks, . Lou
30" Ford model T rim will interchange. The Chevrolet has the lug with slot the Ford does not. Plenty of people out there with 30" Chevrolet rims on their cars. Just need the hole for valve stem redrilled in ether case.
