Rear Tire Discussion If I may?

These are a great tire.
You will not be disappointed and they last
longer than most other brands.

I do not know what engine size you have but we run 3:91
gears in our big and small block 10 sec. bracket Valiants.
It did not slow down either car over 4:30 gears when tested
and got the RPMs down in the lower 6000s. I believe that
helps the service life of our bracket stuff.

1.48 is actually a very good short time for a low 11 car especially with
the tires you are running currently.

I run a 10.5 wide slick on our cars with just offset hangers and stock fender tubs.
