need wheel help for an 05 excursion with lift

Re-posting for a friend. Hopefully will get more attention here...


going to put a 6" procomp lift on an 05 excursion diesel. looking at 20X10.5 wheels with 37" tires. looking to see what kind of back spacing is necessary to avoid possible rubbing. recommendations on tire width, or maybe a different wheel width. i would like the tires to stick out a bit, but nothing too extreme. i'd like to keep the measurements above, but would like to hear any advice on any changes or any similar setups.

thanks in advance.
