Has anyone tried a P225 R60 15----Radial on anything Studebaker , mid 50's on thru..... you get a lil extra width ( 8.9) from stock ( 8.5) yet the tire is a tad shorter, so you see a little more of the tire/ white wall ??

Tire width, wheel width and wheel backspace/off-set all need to be considered as well. The first picture below is an 8" wide tire on a stock/original 5" wide wheel. Note the dark black strip where the tire was rubbing on the top A frame when the wheels were turned to the to the stops. The second picture shows the bright shinny edge where the tire rubbed on the A frame. This is from a 1952, however the basic configuration of Studebaker steering remained little changed from 1951 to the end.

Yes, with the correct backspace wheels, 225 can fit and will work well.

Yes, it's a bad idea to install them on Studebaker wheels. They're just not strong enough to withstand wide radial tires.
