my cl seemed o have slowed down since i put the 19s on is that the reason or you think someonthing else is rong...... bad gas milage too but i had an audi and my cat got clogged and that was the problem has anyone ever had this problem.....

 

its probably slower cuz you put big rims on it yea. plus what kind of 19's? some rims tend to be heavier than others. my car is noticeably heavier cuz of my rims. theres always a catch to looking good

 

19" zenettis ellipse

 

thats a luxury rim right?

 

blanks your not the only one, just recently upgraded to 19's if your in the right wheel diameter& weight, then u should feel shouldnt feel any slower as for gas milage it might affect it. If those settings are off then you are goin to feel a bit slower and ur gonna burn more gas.

 

Bigger rotational mass, more weight, spedo is a off, gas milage should be OK.

Indeed your car is slower, just one of the compromises of the bling, bling.
