Can any of you guys explain whats up with me seeing pics of the BFG DR 315 that had the middle of the tire with no tread on it, yet now when I research the tire I see a different tread pattern on all the websites that sell them.....personally I like the ones with the non treaded middle area and Id like to know if they discontinued those damn things or is it one of those deals where every site just shows the "new" design or something. I may be behind on this but I just dont know because I havent been in the market for DRs until now when I get her pullied really soon.
