'87 R-10 Wheel Size

[bjs87chevy]

I had the Eagle 058 15X8's installed this morning and I had measured the distince between the outside edges of the old rims and it is about 9 3/4 inches. Does that mean that they were 15x10's?. The tires are 235/70/15's

[roundedline]

That isn't the proper way to measure a rim.  Width is inside the lips. Factory wheels were 15x7 standard and 15x8 optional.
