It wasn't the heat that made them hard to take off, it was corrosion buildup on the hub, primarily in the pilot bore. If you're concerned about ease of maintainance, stay away from chrome and alloy wheels, especially clearcoated alloys. Polished (not chrome0 alloys aren't too bad, they wipe off pretty easily. Clearcoat and chrome plated alloys and chrome plated steel have a nasty habit of corroding under the finish, causing not only nasty looking blisters in the finish, but also difficult to stop rim leaks. Your best bet would be to stick with a painted steelie, or if you want an alloy, go with one of the powdercoated ones that's on the market now. With the tire size you're running, I would advise a 15x7 or 15x8 wheel, 15x5 is a bit too narrow for that tire size for optimum performance.
