@Cnsheets I'm expecting the AWD to cost it 15 miles and the 20" wheels to cost it another 15.Based on available vehicle configuration. Meaning RWD models I’m sure.
I believe it’s the added weight but I could be wrongDoes anyone know what causes the lower range on larger wheels? Is it a grippier performance-oriented tire, or just the slightly larger contact patch makes that much difference? Or physics of angular momentum?
The larger wheels aren't just an issue of wheel diameter. They also come with 255 width tires, vs. 235 on the 19" wheels. So that's more frontal area for aerodynamic drag, more tread area for rotating aerodynamic drag, and more tread width for rolling resistance. The wheel size & shape could also have differences in aerodynamic drag, and there could be different tire compounds used.Is it a grippier performance-oriented tire, or just the slightly larger contact patch makes that much difference? Or physics of angular momentum?
@robby-d @Lechon You are exactly right. The added weight of the extra alloy metal in each rim requires a lot more energy to get them spinning upon each acceleration. Like a merry-go-round with none of your friends on it compared to one with three of your friends on it. LOLI believe it’s the added weight but I could be wrong
Performance. Large wheels means lower sidewalls, which translates to stiffness and better handling in corners. In this case, the 255's are 20mm (4/5") wider, so bigger contact patch = more traction (stopping / accel / turning), and again with stiffer sidewalls, more of that contact patch stays planted in more aggressive maneuvers.So what's the advantage of larger wheels and why would I want them? Seems like we are paying extra for a feature that not many want.
The negatives are many - less range, more expensive, and more importantly.... worse acceleration and worse top-end speed with larger wheels.Performance.

Plus, larger rims and lower-profile tires are a style many appreciate the look of.
True.If real life driving was a drag race, tires would only provide just enough traction to launch. But most people like their cars to turn and stop well, tooAnd sometimes even in non-favourable weather
