Right, well in absence of any responses, I did what I should have done in the first place, which is stick my fingers in behind the wheels to feel how much room there is between the tires and springs . Turns out I can barely get my index finger past the 2nd knuckle between the tire and plastic liner piece that sits between the tire and spring in the rear, so that tells me I *might* be able to get away with upsizing to 235/50 or 235/55 but a 245/50 would definitely be pushing it. Guess I'll just play it safe (and cheap) and stick with stock 225/55/17.

You might be able to accomodate that by bumping out the offset a little to a +35ish type wheel.

I'm with you, though my 225s are still good, next set I want is a 245/50.

235/55/17 GY Triple treads on stock rims. About a cm clearance on the outer edge to front of the fender liner at full lock.
No detectable rubbing.

If you drive in wet snow you will find the wheel wells get jammed up with slush. I carry a sawed off broom stick just to poke the slush accumulations out every so often so it doesn't hamper the steering and control. I have actually had to stop every so often in the Mts to perform this act. Going to oversized wheels and tires will only increase the opportunity for this issue if you drive in much snow.
