i find it easier and more accurate to measure just about everything cold, with the engine off...with the exception of automatic transmission fluid. i'm not sure if that tire balancing comment was directed towards me or not, but i can pretty much rule that out...i had a former co-worker mount and balance these new tires while i stood beside him the whole time...he even used the hub adapter which most shops don't even bother with. my steering wheel is as steady as can be even at 100 mph. in my opinion, just about any balancing issues will show up at this speed. i guess these tires just need some getting used to. i don't have nearly as much confidence in turns as i used to with the pirillis, but i have to admit, these tires grip much harder than i expected them to. it feels like the sidewall rolls over too much, but they still seem to grip pretty well. these tires are also very quiet, but most tires are when they are new. i really hope all of this is being caused by "tread squirm", but somehow i doubt it.
p.s. you know what...i don't know if it's because i got used to them or not, but i really like the pirillis now. yeah, they had a short lifespan, gave a rough ride, and they got pretty darn loud, but they felt good. for all the negatives those tires had, i thought those were the most predictable at the limit tires i've had. just a personal opinion.
