FYI factory individual tire weight is 64lbs - I've been told that shaving 10lbs of rotational mass is equal to loosing 100lbs of dead weight. I don't know if this equation has any basis in fact but it does illustrate the drastic performance impact of either reducing or increasing rotational mass.


The clear winner is the BAJA T/A but they are $600 each. Dropping that 36lbs of rotational mass would feel like you gained ~22hp on acceleration and would also improve handling and braking.

I can confirm that I have BAJA T/A  on my m998 and this beast started "flying" just to describe the feel of new set...

you have runflats in yours Serge? might even shave a bit more off if you take them out and only run beadlocks..

mines are straight from military base....  with runflats

hahaha... very nice Serge... very nice an authentic
