I am about to purchase a new set of Foose Nitrous 20x8.5 & 20x10 wheels. I want the new BFG g-force kdw nt but, they do not make it in 275/35/20. If i go with 285/30/20 (overall diameter 26.7) I am afraid of screwing up the gear ratio/speedo and an even rougher ride. If I go with 265/35/20 it is almost exactly the correct (overall diameter 27.3 ) but, not very wide. Here is a link to the website of the sizes.

Any help would be appretiated.

you will be fine with the 285-30, just go buy your local ford dealer after you get the wheels on and have them recallabrate (SP?) your computer for the new over all hight. thats what i did since im running the 255-30-22's out back

Your speedo will not be far off. If I remember correctly, factory tires are 27" in diameter, you are looking at putting on 26.7 Diameter tires. Not a big deal.
