8R19.5 tire replacement

[FrenchBern]

I just bought a 94 Legacy 34 foot and need 6 new tires. Has anyone replaced the original size with the not quite same size 225/70R19.5?
The wheels are original and I am concerned with the wheel spacing on the duals because the new tires are wider.

Hi! I just happen to have new 225/70-19.5 tires on my 2002 Land Yacht which is sitting in my driveway. The rims are 6 inches in width. The spacing in between the rims is about 2 1/4 to 2 3/8 inches. The distance center to center of the tire treads is 10 inches. The space between the bulge at the bottom is about 3/4 inch.

The tires are BF Goddrich ST 230, slightly stiffer than the XRV, but way cheaper.
