That wheel/tire combo isn't slowing him down that much... he's got nice lightweight welds & tires that are slightly bigger. He's gotta be a within a couple pounds of stock if not lighter.

Mlaw - can you weigh the stockers vs. the aftermarkets?

 

I plan to when i get a minute.

 

Didn't change jack this a.m. and ran an 8.38 and 8.6 (no quarter as the distance was too short). Weird huh?

 

Those results are more in line.
I am suspecting you don't have a level patch. You can not tell by eye.
I have actually bicycled a stretch both ways to check it.
More recently I've run it both ways with a vacuum gauge and the Scangauge to verify no noticable grade.
The human eye is virtually worthless for estimating grades.
Sounds like you are having fun though.
