I ended up with no coherent plan, but it worked out okay.
Immediately after delivery, I put AT4W's on the stock 18" wheels. Then winter came and all the deals I had for rims fell through, so I put winter rubber on the stock rims. In the spring, I plan on buying a set of the Tacoma TRD Pro wheels. Love the look of them, so they'll become my summer wheels for the AT4W's.
If I were you, I'd put some nice winters on the stock 20's, then look for something you like in the 18" size for summer.
