Are you talking about diameter or width? The last number in a tire size is the rim diameter, for instance a 31x10.50 R16 means it mounts on a 16" rim. This is the same whether the tire size is listed in metric or inches. As to the width of the tire, this is the second number listed in a standard size (10.5" in this case) and the first number listed in a metric tire size, but in millimeters. A 285/75 R16 would be 285mm wide. Here's a good site to convert that to inches: http://www.4lo.com/calc/gearmetric.htm
As to what width rim you'll want for tires, you really should consult the tire manufacturer to see what they recommend. Generally though, on most tires your rim will be about 2-3" narrower than the tire itself. A 10" wide pickup tire mounts well on an 8" wide rim BUT the manufacturer may have different recommendations depending on the construction of the tire.
Hope that helps.

on really wide applications and anytime the tire might be aired down the recommended rim size is even more than 2-3" narrower example my 19/39.5x15 tires (in this case the width is the first number don't ask me why they did itthat way but just to be different I guess) the recommended rim width is 12 which is 7" narrower than the tire. So the recommendation of checking with the tire manufactorer is always a good bet.

So in actuality your 295/75's are TALLER than a "33-inch" tire since most all flotation size tires are smaller than advertised.
Just thinking positive here.
BTW...Hey Ivan!!! I did something the other day that probably would have mady you spew all over. I bought a SET of NEW tires for my super duty that cost about the same as ONE of my 49's........I had the WRONG hobby, dude!!! Another plus is that they ride a lot better. 255/85-16 (33 x 9).

Yeah, that there is pretty messed up Cody. My sister was complaining a few months back when she had to replace 2 tires on her Nissan Xterra and she was telling me how much more they cost than the tires on her old car. I just laughed and informed her that she still wasn't close to one of my Swampers yet and she'd get 5 times the mileage out of hers. It puts a while new perspective on things.
What I find really ironic is how it seems perfectly logical to spend $400+ per tire for the truck but when I had to replace the tires on the car last year I was all upset about spending $220 on a set of 4.
