for what its worth, and probably done many times on this site, i just weighed up the factory tires here at halftime....
tires were taken off at 300 miles and are 90%+ is my hunch, using stock rims
total 4 factory tires - 118.8#'s
total 4 cheap ass 30x10x15 - 150.4#'s
so I added 32#'s of rotational mass , not sure I can tell, but yes it had to take something away
