I have a 2000 Xterra with 15" steel rims. I saw a new Xterra running 265/70-R16 tires on alloy wheels. As I'm not looking to bling-bling my truck but to fill-out the wheel well, would those fit on the 2000 or do I need to trim the mud flaps?

I searched but no one has addressed newer Xterra rims on an older one.
