Fit, maybe. I wouldn't even try it though. That's a wider tire and an even higher profile, you'll throw your speedometer way off.

A little more in-depth with help from the link I previously posted...
245-215=30mm wider section width. On the same rims this means it will be centered on the rim giving 15mm less clearance on the inside. Combine that with the hight profile of (245/75)7.23 - (215/60)5.08 = +2.15" RADIUS and you may end up rubbing the struts, and while the diameter may fit in the wheelwell while they are straight you could end up rubbing when you turn the steering wheel. Fitting on the rims shouldn't be a problem though, typically tires will fit on rims ±1" in width easily and higher profiles make that number even bigger.
And as I stated before regarding the speedometer...65MPH will actually be about 76MPH! The only good thing about that is the larger circumference means you will cover the same distance with less revolutions of the tire (less wear?).
As far as your traction or ABS is concerned though, those systems work more on a relational (wheel to wheel) calculation than anything to do with your actual speed so they shouldn't be affected enough for you to notice.

If you decide to try it, I'd suggest a set of wheel spacers or a set of rims with a different offset to push the wheels out.
Since everything is computerized nowadays, you may want to do some research and see what it takes to reprogram the speedometer.
