I just don't see it!

But that depends on the actual wheel. The Enkei RPF1's I run on my Duster in 18x9 and 18x10 with 275/35/18's and 295/35/18's were lighter than the 15x7" cop wheels with 225/60/15's that they replaced. And the total wheel/tire diameter remained similar. If you buy cheap large diameter wheels and tires you can add weight, but just because a larger rim diameter was used doesn't automatically mean the wheel got heavier.

Yes. You gotta watch the weight. Not all rims are the same.

To your enkei’s credit, they were 2” and 3” wider. And tires were wider too. More fair would be 18x7’s with 225/45/18. Interpolating using your measurements, those would be around 39 lbs each! …11 lbs lighter than cop cars’.

But also where the weight is. If more of the weight is further from center, the moment the inertia is greater. And IF there’s high enough difference, it will effect braking and acceleration.

I’m talking the chrome donk 22” and 24” rim people put on SUV’s and Trucks.

This guy got 26 pound difference between factory 17” rims and tires versus 24” hellcat replica’s. That’s a 7” difference in diameter.

Fast forward to 4:00 minute
