JW, can you post a plea to someone near you to loan you a set of stock wheels/tires for a few weeks? If you lived closer, I'd loan you mine
If it's your only car, it appears that you have 2 choices... find a set of stockers to borrow or have them get you a single wheel to use until the IF wheel is returned.
I can't imagine that IF would take long if you call and explain the circumstances. Maybe they can turn it around in 1-2 days and get DT to pay overnight shipping both ways?
