Just put new Wheels on

And larger wheels will give you better MPG -- not worse. Simply put, a larger wheel and tire travel a further distance after one rotation than a smaller diameter wheel and tire -- requiring less rmps for said distance traveled -- at a cost of torque and "power".

You could say weight would make the difference. The reason "alloy" wheels were invented was to save weight. But they can weigh more than stock wheels -- in either case, you may be sacrificing MPG when acceleratingly, but when the car is up to speed the added weight will tend to stabilize the car at said running speed -- further saving gas.

That all said, I got 15" wheels with the normal amount of rubber for no other reason than to lessen the chance of curbing the wheel. There are many reasons to choose wheels. "off the line" is one -- one I don't care much for -- but if you wanted to get the best MPG from your wheels and tires -- get the biggest thing that will fit under the strut.

Guys, don't take this as hating on big wheels.

But really, that post is so erroneous it hurts to read.

Larger tire rolling diameter *increases* mpg? ok, see I thought rolling a heavier, bigger tire that's farther from the axis of the wheel would take more power, not less.

"Get the biggest thing that will fit under the strut? You've got to be kidding me right? So 21's with truck sized tires are good for performance and mileage? news to me.

You might try *thinking* in a common sense way before posting. Lighter, smaller tired, wheels will ALWAYS outperform a larger, heavy wheel, with big tires. Ever hear something called friction? You know, how it takes more power to turn a wider wheel? Ok good.

So, all things being equal (car, tire size, ride height, air pressure), a 15" wheel that weighs 17lbs will give better performance and mileage than some 10lbers? NOTE: this is not a hard question, if it was, supercars wouldn't place such a large emphasis on making any weight that's unsprung as light as possible.

not a good idea.... way too small of a tire

[brickhardmeat]

205/50 R15 not too small



I know you say 205/55 R15 or 225/55 R15 but I checked the tire calc and205/50 R15 is by no means way too small. It is within the reccomended tire size. I'll register slightly over the speed limit. Sure 205/55 R15 is a bit closer to stock but...



here we go...

Lots of guys running 205/50 R15

now I aint puttin' no shity looking 40's on there

Correct. It's not *way* too small, sure it's a bit too small, but it better suits a Yaris size/weight than a 225/50 15, that's for sure.

Ideal *sizing* for the Yaris (IMO of course) is 195/55 15 or 195/50 16. If a sticky 195/55 15 was good enough for a 195 hp Integra Type R from Honda race engineers, it's ok for a Yaris.

Thanks Nimble but you are well aware that the Tire Nazi knows all.

I really dont want to do this,but I will.There is no diffrence if you have 15's or 17's,if the diameter is the same,everything else will be the same,because the car is still turning a 205,or 215.But for the most part,people go wider when they go bigger,which does add weight and rolling resitence,thats where most people loss performance,I myself use 35psi on all tires to help balance out the diffrence,Ive got 17's instead of my stock 15's.
Think of it this way,you could have a 1 incn rim,the rest just tire,but the diameter is still 215,the engine would act the same,ofcourse you wouldnt stay on the road long;),so that said,I actually feel alot more stable with my 17's and skinny rubber,and just as quick as stock,actually alot quicker now.

Looks great! But when you say amazing difference, what exactly are you referring to? I've got the shit stock Bridgerock 14s and am very unsatisfied with the handling...want to upgrade to alloys but to what size? 15,16 or 17s? And why?

[Black Yaris]

y-rag what kind of driving do you do? and i can help answer those questions for you

I retract my previous statment and added 205/50R15 to the Official Tire Guide
