Can a Yaris fit 13" wheels??

[MrWideTires]

I'm looking into getting a Yaris.. but I'd love to fit some 205/60-13s.. can these cars fit 13" wheels??

[RacerFreakXXX]

I believe this has been covered but I can't find the thread. I also believe the smallest we can fit is 14"

[RUFFSTUFF]

Why?

[CASTREX]

Yes, the yaris can rock 13's

Do a search for lenso vpd and you'll see

i have some 13" but never fitted them ... found them on the side of the road

mojoyaris has 13"x7.5" Lenso VPD wheels, silver and gold on Toyo R888 GG comp 225x45x13

Smaller wheels/tires=less rotating mass. Lighter=faster acceleration.

Nothing like buying a Yaris and then spending money to try to keep up with Corrollas...


The unsprung weight loss of the smaller wheel may (assuming wheel characteristics are the same i.e. not going from 15" alloy to 13" steel) improve handling characteristics, but is there much in the area of straight line performance gain? Except if you don't adjust the aspect ratio for the minus-2 sizing, then you will have higher gearing which will improve acceleration at the cost of top speed. Running a higher aspect ratio tire to compensate for the smaller wheel is sure to hurt cornering performance... as the tire shifts off-axis with the wheel.

Actually cornering is improved.

Removal of unsprung weight not only improve straight line acceleration, but also overall handling and breaking.

And what are you talking about keeping up with a Corolla? A Corolla can't keep up with a Yaris... not even in it's dreams...

Wheels are unsprung weight. Anything the weighs down the suspension is sprung.

Yaris vs. Corolla... Fight!

Yeah... edited. You got the point though.

Any way... the Yaris reacts very well to wheel/tire weight reduction.

Also a good point on the positive side of shortening the gearing. Not a good idea for a DD, but the Yaris would benefit of a shorter ratio for the track or autoX

[RUFFSTUFF]

Neat.

if you run anything other than rcomps on the 13's or 14's, i find the steering is squirmy at the limits due to sidewall flex.

i had 14" steelies w/ fuzion hri's (185-60-14) and on hard cornering you could feel the tires squirming around...

what psi were you running? 32, max side wall (if so... what?)... psi adjustments might be able to make up for the issues you had.

[thebarber]

for DD i was at 35psi

auto-x i was 40

its a lot of rubber to not flex when you have all seasons

are you saying aftermarket rims/tires, if not adjusted to correct size, causes loss in top speed?

I think he was just going by the general rule of thumb.

Shorter ratios foe better acceleration and longer ratios for higher max speed... although is not as simple as that....

Actually it is. If you change nothing but the diameter of the wheel and tire, acceleration and top speed will change accordingly. And oh yeah, your speedometer accuracy will also be affected. The diameter of your wheel and tire is based on the rim size, the tire width and the aspect ratio. This overall diameter multiplied by pi will give you an approximate rolling circumference. I say approximate because without taking a physical measurement, you're left with the manufacturer's size rating and they are not very good at providing good measurements. Tires labeled as the same size can actually be quite different, even within the same manufacturer. On my Mazda3sGT, I went from a 205/45-17 OEM to a 205/40-17 Fuzion tire. It was a noticeable change in acceleration (quickness). Top speed originally was limited to 114mph on the speedo (112mph GPS)... the rev limiter still kicks in at 114mph on the speedo, except that it is now only 105mph on the GPS. Keep in mind that speedos do not report actual speed, much like gas gauges don't report actual fuel level... only different. :)
