Wonder why the weight adjustment is

2600-2999=0.1

Seems like there should be a closer spread like.

2800-2999

2600-2799

Etc

 

I also see there is a 0.7 for tires 245 and smaller, it would seem that small cars on 245 would not be at a disadvantage. Maybe it should apply only to large cars choosing to go on small tires.

 

Can Anyone explain.

Thanks
