Oh by the way, the Edge wants circumference not diameter, my mistake. I haven't gotten around to measuring it yet.

I'd have to say the cop's radar was off or your buddy had some serious issues with speed-o calibration, because roughly, switching from 245's to 265's the speed-o will be 2mph off. Switching from 245's to 285's it will be 5mph off. So for you to be 6mph off on 265's just doesn't compute. Buy hey, try and argue that with a cop

Whatever the deal was, the truck had 265's on it instead of stock and I got pulled over for going faster than what the speedometer read. That experience makes me question 265's either not throwing the speedo off or even making it more accurate. Do you see where I'm coming from?

Looks like I'll have to buy a programmer of some sort to fix the speedometer to my satisfaction. Could be worse I suppose. So, what stacks well with a hot juice on an LBZ?
