15" wheels on 03 Disco 2

Have a chance to purchase a nice of 15" wheels and a brand new tires 32/11.50/15. Fit the rims and they rub on the mud/dust shields ( I can trim those with a grinder). Another issue is this rims are 15x4.75(120.65) and our trucks are 120mm, do .65 of a mm make a difference?. The hub center is wider but I can always used hubcentric adapters if it is necessary to avoid vibrations. I like the idea of 15" tires, cheaper to purchase, more variety and more meat on the tires.
My truck is lifted 2" already so I don't believe clearance will be a issue, I am not new to trucks and wheeling but never had the honor to own one of these cracker box(LR) but in all honesty great rig when I compare to a old International Scout and a Jeep TJ. Any imput will be appreciated...Pete

Does anyone knows if installing a 120.65 bolt pattern into a 120 makes a difference?????....

i've never put 15's on any of my discos. it's always easier to borrow a spare rim off someone in a pinch when everyone you know runs 16's with the same pattern. I do know someone who put 15's on and he actually removed either the front or rear dust shield, can't remember which. sorry, can't help you regarding the 120.65

What Ed said, we all pretty much run 16's (I run 265/75's without issue). I'd think .65mm would make enough of a difference because you don't want to put too much extra weight on these hubs if you don't need to.
