I had my 18" Halibrands widened to 12" and I'm running Toyo R888R's 335/30/18's... incredible traction, you really have to try to get them to break loose when they are warm.
My car has 540+ to the wheels through a TKX and 3.73 gears, so they are being put to the test.
For me wear is not a issue, I care about traction above all else. If you want the best traction go with my setup.
