Seems real interesting most race teams try to remove body and chassis weight rather than lighter wheels and tires.
If I was going to spend a pocket full of cash to make my street car faster it wouldn't be spent on wheels and tires which wouldn't produce near as much performance as some engine or trans upgrades for the same bucks.
Really?
The 4" skinnies they run for front tires ring a bell?
Back tires are optimized for traction, maybe at the expense of possible weight savings.
Of course your examples are straight line guys anyway, the only handling they care about is making the turn back to pit row. Anyone interested in handling and considering new rims would be smart to look at weights as well.
