I would guess that using a cheaper wheel for a pro-longed period of time would cause some problems. I am basing this assumption on an earlier posting which reported problems driving with a mismatched set of tires, see http://www.greenhybrid.com/discuss/a...blem.9841.html .

I would imagine that not only would you want to have a matched set of tires & wheels, but that these tires should be rotated on a 5 tire rotation schedule to minimize problems due to uneven wear. If I were driving under the conditions you described. I, personally, would just spend the extra money to match the tires.
