will 275/60/15 fit 71 Duster ?

I'm running 275/50/15's nitto drag radials on an 8" rim amd believe they're good for 7" rims as well. Smaller diameter than the 60 due to the shorter profile. I have the srpring offset kit not the relocation kit in my '67. 4.25 backspace. They fit great, look awesome and are super sticky tires.
