You won't need the spacers for the 285's, they will fit fine. I think others have gone to 305's without issues. I have 285 on now so I'm sure others will comment about the wider tires.

I know 315's will not fit on a stock EX. 305x70x16 might fit on a stock rim with no rub... but that means you are only using a 16x7 rim. Tire says narrow and looks smaller that it should. If you put a 305 70 16 tire on a 16x8 rim from what I have HEARD FROM THIS SITE... you get some rub at full turn with a STOCK EX. A 285x75x16 tire is only 1/2 inch smaller across than a 305x70x16... it is the same height. Roughly 33 inch. I am running a 16x9 inch rim with a 285x75x16 tire... no rub. My brother is running a 305 70 16 on a 16x8 inch weld rim on his truck. When we park our trucks next to each other the tires look the same size. The smaller/wider rim gives the allusion of a much bigger tire. EX: 16 inch rim VS. 20 inch rim. The 16 inch tire will look much beefier (bigger) than the 20 inch with the same tire mounted.
If you go with a 305 you might want to put a small lift on your truck. Check out leveling Kit Questions?? Post on the forum... good info if you do want to try a 305 with a bigger rim than stock.

I had 305's on the stock 16" rims and they would rub on the leaf springs when locked.
I now have 285's on the 18" rims with no rubbing. Once these tires are gone, I'm going 295's....

I believe the OP's question was for using spacers as well which would eliminate any rubbing of the springs.
Btw, don't use 2" spacers as that would put way too much leverage on your bearings. I believe 1/2" spacers are all you'd need to clear the springs.

I have 305/50 20's on GIO rims. Not sure about the spacers but my 305's only rub when I turn all the way to the steering stop. I just avoid it and it doesn't make a big difference in the turning radius that I can tell. Some may think my Ex looks a little on the pimp side but I think the wheel/rim combo looks great. To each their own.....
