That's gay. Someone had their head where the sun doesn't shine.
NO someone had their head where the sun DOES shine. The 8x6.5 pattern with the dia. studs was decided on MANY YEARS AGO....back when the designers/engineers of 2500/3500 pickup trucks didnt even have the faintest dream of a truck with a 13,200lb GVW or 22,000lb towing capacity.
8x6.5 is simply not a big enough pattern to properly handle the huge GVWR and GCWR of these new trucks. So they had to make it bigger. Why do you think dodge is still stuck in 3rd place now with their ratings (because theyre still on 8x6.5 duh) and why do you think FORD pulled ahead of GM/dodge in the ratings/numbers area YEARS ago? (because they moved away from 8x6.5 years ago, duh)
Despite what all you people want to think or ASSume, GM didnt change it in some grand stupid little scheme "just to piss us off" or "to promote and stimulate the aftermarket wheel economy".
It would have saved GM hundreds of thousands of dollars to just keep 8x6.5. Do you REALLY think they changed it just for grins?
