John, I don't know if you remember any of my last posts, I am the guy who won't use aftermarket wheels because the offset is off a couple of millimeters from the factory wheel specifications. I am that picky about my equipment. But in this case, the width is equally added to the centerline of the wheel, so the net effect on the suspension and turning radii is zero.
I like to check everything out, that's why I bought the caliper to measure tire widths. All the data I list is pretty darn accurate. Part of my check out was checking clearances with the 235s. Don't try this at home, but with the engine running in park, and the emergency brake on, I rolled close along side the front wheels on both sides on my creeper. I had my son crank the steering wheel full lock both directions (you get more angle with the power steering pump energized by the engine), and felt around the inside of the wheel wells. Actually, the closest clearances are out at the tread radius, not at the mid sidewall where the tire is widest. The tightest fit is full cranked, trailing edge of the tire, against the inner fender panel. I can still put my hand between tire and the panel. That is, palm on tire, back of hand towards panel. What's that, an 1.25" or so? Quick, where's my caliper.... And that's with the steering wheel turned against the stops, something I never do while driving. There is tons of clearance everywhere on the rear wheels.
Remember, I only tried this with 235/60-16 WRs. I don't know how another tire would work. Being a snow tire nut, I have had a few. I had some Gislaved Frost years ago. And some Continental Contacts (when Contact meant snow tire). Nothing compares to these new generation tires.
