Damn, that is shitty. I felt sorry for you too bud.
Thanks Idjiit for answering our questions. Tho, why is people so obsess with bigger wheels when it use more gas?

No Idjiit ...... I was comparing the 15" stock steel wheels to the 16" alloys, no tires. I did the same with my 18" Dymags (this was for my motorcycle) and the stock Honda wheels, but that is unfair as the Dymags really are magnesium. I would be VERY hesitant to use magnesium wheels on the street, even if cost was not a factor.
Rolling resistance is very difficult to determine. There are so many factors to be considered. For instance on bicycles a larger wheel has less resistance than a smaller wheel (700C vs 650C), but the smaller wheel accelerates better. If you want to be dazzled by techno-babble read some of the articles in the Triathlon mags on rolling resistance vs aerodynamic drag. |

Perhaps the obsession is due to mis-information. I know I never thought that an 18" alloy wheel-tire combo would be heavier than the stock steelies + tires. You live ....... you learn.
Or maybe the 18" dudes are just going for that ................... look. |

Man ... that IS the pits. If there was more than one dealer in the area, I'd take my money and walk. Manual/automatic that is a pretty basic thing to mess up on. Next will it a be sedan-liftback mistake????? Sorry Goose, didn't mean to cause you more worry!

The mileage issue isn't really a big deal to me - I just wouldn't want to trash the great mileage by making what is (for me) essentially a cosmetic change. Obviously 18's are much larger than the Toyota engineers originally spec'd for the car, so I'm sure it would change something in this regard.
Come to think of it, would there really be much of a difference in overall circumfrence between a low-profile (30-35 series) 18" wheel/tire combo and a 60-series 15" wheel/tire combo?

Found a good article on Tire Rack's site
Obviously, Tire Rack is trying to sell folks larger, upgraded tires. Despite this fact, their information looks sound. Based on the linked article, going with a bigger wheel/tire isn't going to make a big dent in mileage. Food for thought.
Enjoy... http://www.tirerack.com/tires/tirete....jsp?techid=29

But essentially you were right Idjiit ........ reducing weight, especially unsprung weight is certainly a factor. If the rolling circumference, and the frictional co-efficient are the same the lightest combination wins the gas mileage competition. The advantage might vary city/highway, but it will remain an advantage.

Thanks for all the info, guys. I'm still not sure if I would get the TRD wheels -- they're pretty expensive and I don't even have the car yet!
Also, thanks for the support with the dealer's screw up. Apart from having to wait a bit longer, there's been no harm done. I like my local dealer, and he's been a straight-shooter with me on past deals. Since my dealer has already gotten another car with the correct specs (he assures me) set up for shipment, I wasn't too disappointed. I'm almost happy because I'm still getting a factory-fresh (no dealer trades for me) Yaris. I thought that this foul-up meant that I'd either have to take a color I didn't want or have to wait forever. Chalk up another interesting car-buying experience...
