18's with 275s on a Duster

I would like to make a note. Not all 275mm tires are the same width. A lot of the 200TW tires that have come out in the past year or so are actually wider (by approx. 10mm) than their predecessor's at the same size. While they are wider, most tires aren't taller for the same size. Notice the size difference between a Falken RT660 and RT615K+.

RT660 (11.2" wide on 9.5" wide wheel): https://www.tirerack.com/tires/tire...ewall=Blackwall&partnum=735WR8RT660&tab=Sizes
RT615K+ (10.8" wide on 9.5" wide wheel): https://www.tirerack.com/tires/tire...all=Blackwall&partnum=735WR8RT615KP&tab=Sizes

My main point... Measure, measure, measure. And even after that, you might still rub.
