fact (1) is a 215/35 is slightly smaller than stock, to stay exactly stock diameter you would go with a 225-30-18....

fact (2) if you have a wheel, one in an 15 inch and one in 18 inch, exact same wheel only different sizes, the 18 will weigh more, unless you did find the one wheel manifacture that makes wheel out of a substance lighter than air, then I stand corrected, added weight decreases gas mileage

fact (3) a 225-50-15 will corner better than a 225-30-18, why you ask? side wall flex.... I will explain... To keep traction on the road during a high G turn the tire needs to flex to keep the contact patch to the road. A 225-30-18 has 1.5 inches less side wall than the 225-50-15 therefore has less flex in the sidewall, therefore can not corner as fast or as sharp as one with 225-50-15

Ask anyone who truely races they will tell you the same

16's on up on a Yaris, all show, no go

My 18's on 215/35 have about a 1/2 inch more diameter then the stock 15's I have now. Basically, no difference. Also, the racing 18's I bought are slightly lighter then the stocks. I don't agree that you say handling decreases with a bigger rim. Anyone who's ever driven a car with 18's-20's on it will tell you that handling increases with a bigger rim. But that's just my take. I think big rims get a bad rep from racers... But like dude said. To each his own.

I guess I'm just used to seeing people who are 5'8" 150 pounds. Sorry to all the "heavyweights" out there. I had no idea there were so many of us 6'3" 210+ fools driving the Yaris.
