The scale I used may not be spot-on, but it is pretty close as it is a digital shipping scale. My gram lights weighed the same and that is what they are supposed to weigh so I trust that is is pretty accurate. On top of that the wheels just felt light. I have handled quite a few wheels lately so my "arm scale" is getting pretty well tuned. My FN's were the 17x9 +20 4-luggers and had a TON of hub on them. That is probably why they weighed about a pound more.

As for your tires... those are tall and your going to have some clearance issues. With the 275/40/17 RA-1's I'm real close to rubbing everywhere and the car is not even that low. The 245/45/17 R6's in the garage are a good .25"+ taller IIRC.

I checked with a tire size calculator and the difference in CIRCUMFERENCE is only .06" between 275/40/17's and 245/45/17's. I dunno where you get 1/4" difference in DIAMETER from. If you fit 275/40/17's I can fit the 245/45/17's with no problems. My fenderwells are excessively clearenced for the 255/40/17's that I have been running so I see absolutely no problem. I will be running a 4.36 rear end gear as well (currently 3.93) so the gear ratio difference is no concern. I can't be picky with free tires, and besides they will only last for one event. Then I will be running either 255/40/17 ra1 takeoffs or brand new 245/40/17 hankook z-214's. It depends on whether or not I can find a matching pair of ra1's in time. I wanna run the shittiest tires first and save the best ones for later.
