Tire size question

Shot in the dark here...

On my '06 GMC I am running 245/70-17 tires; stock size.
My truck has been lowered 2" front (control arms) and 4" rear (hangers/shackles).
I have found what I think is a pretty good deal on a set of suposedly new 20" take-offs. The '07 or '08 rims that look like the mid-80's Iroc rims.
These rims have the stock 275/55-20 tires.

By my calculations these tires are more than an inch wider (9.6 vs. 10.8) and 1-1/2" taller (30.5 vs. 31.9) than my tires now.

Has anyone run a tire size this large on a truck lowered like mine???
It looks like I have plenty of clearance but I am not sure.
