I was not aware of the Falken tires in 275-40-17... I usually do my searching on the Tire Rack's website. At this time I don't own any 17" rims, nor any 18" rims... but I do own 4 15x8 vintage minilite rims (street/hwy new tires BFG T/A 255-60-15 front and 275-60-15 rear); 4 16x8 vintage minilite rims (intended for driving to/from hi-speed road course lapping sessions/competition hi-speed events... new BFG G-Force Comp-2 255-50-16); 4 16x10 lt wt road race rims (Centerline X-series) with Hoosier A6 275-45-16 for competition pylon autocross events, but these are now ~1 years old and I wore them out/corded after running ~40 50-second med-speed autocross runs in the Sept 2012 All-Mopar Monster Mopar Wknd at Indy/Luca... I would like to get another same set of these ultra-sticky competition autocross tires for serious "season championship" events... but.. the cost is prohibitive to me (~$1300) for another 1-2+ years for now.... these tires would have to be trailered as they are not good for the stret/hwy even though they are DOT-approved... but in the varius racing classes that I could compete in (at my choice clubs, etc), these are the ultimate to WIN.. and I do want to WIN!.
I'd like to get a set of 200 tread wear tires for those certain competition events that have that rule of "200 tread wear minimum"... these 200 TW tires could be driven on the street/hwy, but very minimally so to prolong their life and competiveness.
I don't forsee any 255-50 or larger, like 275-45, 200 tires being offered in 16" diameter... if they did.. then I'd probably buy them more easily than the replacement Hoosier A6.
I'm a "race competitor" first before I'm a street/hwy/cruiser-driver, and the car shows can mostly wait (often boring when I'd rather be "showing my car on a road race track/autocross event".... that's the main reason I have my car... driving competition in a Mopar!
Just 2 factors: Time and money... if I had the money I could buy the time!
HAPPY HOLIDAYS!
