Actually ordering direct from www.competition-rc.com
, the price on the website is identical to what GQ dealers are supposed to be selling them for. Unfortunately GQ tires doesn't have a big name, big drivers, but their wheels are much stronger than anything out there, wear is quite a bit lower as well. I have had gas and electric racers tried GQ in the past year and no complaint from any of them.... well, except some complained about the color of the wheel.
I'm in no liberty to address the cost and/or dealer pricing, but the figure you have in mind ($8 ~ $10) is ULTRA low.
