Why 20" wheels
A friend of mine is after me to buy a new car** and she found the
Buick Cascada. I've wanted a Buick for a long time, because I like GM cars, but the Chevy I-forget-the-model-name was so cheap. Bucket seats but not even a center console. And I've avoided Ford and rice-burners. And the Cadillac seemed showy, so that left a Buick. And the Skylark was beautful (And my Buick was okay too. I forget its model name. Centurion?) But the Cascada comes standard with 20" wheels, and they say that like it's a good thing. Well if you're in the Gran Prix races, I'm sure it's a good thing, but I like a comfortable ride. They don't even mention smaller optional wheels (although I'm sure I could get them if I pay someone to go to the Chevy dealer and get them there. (It also has "sport-tuned suspension" I don't want that either, but I suspect it's not like a violin that you can retune to something else. It also comes with a black top, no other choice given. Don't these designers ever drive the cars they design? It's like the charge-card email notifications all over again. (I had two convertibles with black tops. When the second one needed a new top, I changed to green, to match the turquoise car, which was imo primarily green, and it was much better. Since then I've had tan, a rather light version of tan.) I suppose if I order the card before it's built, I can get a tan top, and they probably "won't charge me much extra", but any negotiation on the price will be over. I've never bought a new car, but the idea was to get what I wanted, not what I don't want. For $35,000 dollars, which I gather is not much these days, but they don't offer to let me spend more and get what I want. **and indeed it will be possible to get a 7-year old car like I like, but v. hard I think to get a 3, 4, or 5 year old car, because they stopped making Sebrings, Solara convertibles, and maybe only Mustangs are left. Any other new or late model American convertibles bigger than a Miata for sale these days?? At least as big as a mustang. |

Look through the magazine racks of your grocery store, Walmart, etc. Some of the car magazine publishers had an issue showing all of the model year's new buggies. A number of the "foreign" models are built in the U.S.A. if that's an issue. |

Camaro And on the subject topic, the 20" rims will make for a better ride than the smaller. The only one I would strongly recommend to avoid is the 19" and only because they're so much less common that tires are in ordinately expensive. I didn't think about it when bought the Enclave some years ago is how happen to now know... -- |

Why 20" wheels
Improvements in suspension design have allowed for lower profile tires with larger diameter rims - up to a point. As Pawlowski stated, those 20+" WAGON WHEELS are cosmetic, nothing more than libido boosters or for cruising the beach parking lot on a Friday evening. |

Depends on the car, but whatever sized rim allows a 70 series tire to be the right rolling diameter is about as good as it gets. Not only the right rolling diameter, but fits the wheelwell to make it look decent, and llows full suspension and steering movement without hitting body or frame. Different for each vehicle. 16 inchers fit the bill for the majority of todays cars. Yes, and many offer 17 or 18 on the upscale models. Common to also have a $12,000 price difference between the basic and fancy models of the same car. |

I'd say for many cars, probably most, styling, having the wheels look cool, is more important to the customer than all the above.

The larger wheel has more metal due to the length of it's spokes and the metal around it's circumference. We all know that more metal weighs more. |

Unless on some high performance car (and even then it is doubtful) just about everything on a car is made for looks. The average car buyer does not have any idea about the handling or other advantages of the tire size. Your statement may be true, but that doesn't change the fact that the trend to larger wheels and brakes was born on the race track. |

Put a chalk mark on the tire's sidewall the lowest point, continuing the mark down on the pavement. Drive forward until the chalk mark is at the lowest point and again mark the pavement. Measure the distance between the two marks on the pavement and do the math. Voila, the rolling radius. |

As, over heated pads aren't providing much if any stopping ability; and depending on the amount of excessive heat and resulting damage, they may not provide much or any stopping ability when they cool down to normal temps, either.

Funny, I thought we were talking about Micky's car, not a race car, driven at extremes. But go ahead, show us a study of race cars and the effect of brake component color being significant and we'll all look at it. |

I buy quality cars by Hyundia now including a Korea made Genesis. Love driving it. There are several reasons for larger diameter wheels, none of which is styling. 1. Larger diameter wheels allow larger diameter brake rotors that will result in a greater mechanical advantage. This results in increased stopping power. How much braking does the average driver require at legal road speeds? That depends. Imagine you are traveling at 60 mph and you suddenly see an obstacle 150 feet in front of you. Your reaction time decreases that distance to 125 feet and your car takes 130 feet to stop... do you really need greater stopping power? Only need more braking power if the tires can hold it - otherwise the ABS just shuts them down anyway. That said, I DID put bigger brakes on my Ranger - it really needed them BECAUSE I put on bigger wheels. So which came first - the chicken or the egg?? With the little 14 inch wheels and tires the 10.25 nch rotors were plenty adequate. With the big boots on the 16 inch rims, the extra leverage made the 10.25s imadequate, and the 11s made a big difference. Same pads and calipers, just applying the braking farther from the axle. 2. Larger diameter wheels, for a given rolling radius, reduces the vehicle's un-sprung weight which will allow the tire to remain on the road, where it's suppose to be, improving safety and handling. That depends how heavy the rim design is. A lot of the big rim low profile tire combinations are every bit as heavy as a lot of smaller rim taller tire combinations for the same rolling diameter. True. Styling has no weight requirements. 3. Larger diameter wheels in conjunction with lower profile tires will improve handling as well. Styling is nothing more than an offshoot of the above. Not in most cases. In most cases the big wheels are just more "bling" Again, whatever. |

Imagine that your tires don't have infinite adhesion to the pavement and that any braking system can lock up the brakes. In other words, it's a lot more complicated than you assume. |

Gordon said something about there being more air between the spokes, IDK, must be some new science thing. Even if you factor in lower profile tires on the larger rims, I doubt you get less overall weight for the larger rim and tire together. |

The Car and Driver Frank posted at the end of the thread starts off by saying. in general, the bigger rims and tires weight more. "In general, larger wheels are heavier, and additional weight hinders performance. " The article is from 2010. Maybe that's why he didn't test 20" rims. |

It *may* decrease the unsprung weight. Some of the 20" wheels marketed for the bling factor may be heavier than a smaller wheel/tire combination with the same rolling diameter. |

But thatb does not explain the insanely low profile tires. 80 profile 15 inch tires can ve taller than 50 profile 20s. |

And the Cadillac seemed showy, so that left a Buick. And the Skylark was beautful (And my Buick was okay too. I forget its model name. Centurion?) But the Cascada comes standard with 20" wheels, and they say that like it's a good thing. Well if you're in the Gran Prix races, I'm sure it's a good thing, but I like a comfortable ride. They don't even mention smaller optional wheels (although I'm sure I could get them if I pay someone to go to the Chevy dealer and get them there.

Don't these designers ever drive the cars they design? It's like the charge-card email notifications all over again. (I had two convertibles with black tops. When the second one needed a new top, I changed to green, to match the turquoise car, which was imo primarily green, and it was much better. Since then I've had tan, a rather light version of tan.) I suppose if I order the card before it's built, I can get a tan top, and they probably "won't charge me much extra", but any negotiation on the price will be over. I've never bought a new car, but the idea was to get what I wanted, not what I don't want. For $35,000 dollars, which I gather is not much these days, but they don't offer to let me spend more and get what I want. Bigger wheel are as much for appearance as anything else.
