I currently have the 33x12.5x16 SSRs on the stock suspension - would highly prefer the ATs for my 90% road and 10% desert driving, but hey, to eah his own...
My recommendation is to go with he IROKs in the 33" flavor (are they out yet in the US?)...man these tires do wonder on my Disco and they just propel like crazy...outperforms anything else out there!
