I believe actual tire sizes vary somewhat with each tire manufacturer.
As a rule of thumb, if you look at the various tire size comparison charts available, a 215 / 70-15 tire will be appoximately 1" shorter and 0.75" narrower than most 235 / 75-15 tires. I prefer the look of the 235 / 75-15 myself. I think it fills the wheel well nicely.
If I were buying wheels as well, I'd be looking at 16" wheels; as 15" wheels aren't as prevalent on many of the newer vehicles in a few years now, so the tire selection is better with 16" tires. If you already have wheels, make sure you know what width they are; that will narrow your selection as to what tires are designed to be run on them. Example: Last Spring, I was going to buy some narrower tires for my '65 F250, but when I spoke with the tire dealer they told me that the tire warranty would be void if I had them mounted on my rims. My rims were wider than what their recommended specifications allowed. So I bought the wider tire to ensure their warranty and load rating capacities would be upheld.
Lastly, be aware that if you vary your tire height much from OEM height, it WILL change what your speedometer reads........ both in mph and on the odometer.

I have 215-75-15 on mine and they are close to the original size.
F series tire.
I would like to run bigger tires but first the body and drivetrain. I would run a 275 or 295 18" rears with a bit mor wheel well and 255 17" in the front for a good stagger.

Does that wide of a tire rub on the inside when you turn into a sharp driveway?
I'm thinking those must have a thread width of close to 10.75"...
Maybe you're running a wheel with lots of offset?

are about two inches taller, but they aren't that wide and they rub on the inside of the wheel well if I turn the wheel all the way to the right or left.
