tire change from 16" to 15"
Something to keep in mind while selecting new tires/wheels for your '49 coach is the wheel well clearance. Vintage single axle coaches are noted for extremely tight wheel well clearance so it is critical to have all measurements handy to determine whether a specific wheel/tire combination will fit. My suggestion would be to get your tire/wheel dealer involved in the ordering process so that he will be more responsible if the ordered setup doesn't work with the available clearances. Have you considered how much your proposed change might impact your road clearance? -- even with the factory specified rims and tires gast station driveways and some village street drainage systems can cause the rear of the coach to drag.
Good luck with your investigation!
