Nope. The new 07 Tundra's have a weird lug nut pattern. It's something like 5x150. So it will be a few months before manufacturers have wheels available. I believe TRD might be offering a 22" wheel though.
Dealers here in the SE are offering BBS wheels and Mich LTX 275/55 20 for about $2200. I am thinking about ordering these on my 8242 ( Dbl Cab 5.7 6Spd SR5 ). They are a flat sliver in color. I really want chrome. But was told like it was stated above, 5 bolt 20in Toyo pattern not avail except by a dealer. Find it hard to believe.
