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

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

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

Why?

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... :thumbup:


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. :iono:

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... :biggrin:

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

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.

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. :)

oh... cause i ask because, my yaris no longer hits the 118mph mark, i can bring it up to 105 or so... and i never knew the cause, ive tried new air filter and such. could that be a reason?

Before we all go off on rants and raves why don't we wait for the OP to came back and say why they want 13's?

If you made a wheel and/or tire change that resulted in a lower diameter then your actual speed will change accordingly. As a note, aspect ratio (i.e. 40,45,60, etc) is the ratio of the sidewall height to the tread width. So a 185/60-14 would measure as 185mm wide, 185 * 60% = 111mm sidewall height on a 14" wheel... 14" is about 356mm so overall diameter would be 356 + 111(2) = 578mm or about 22.8 inches. The rolling circumference would be 1816mm.

Change the aspect ratio on that tire to 55 and the diameter changes to 560mm. The circumference would be 1758mm. That's a reduction of 3.2% from the 60 series. Theoretically, since your speedo doesn't register the tire change, this scenario would result in the car going 3.2% slower at the limiter.

Also of note, that if not limited electronically, the change in gearing can actually let the car travel faster by placing the hp peak at a point where the frictional losses of air resistance can be overcome... i.e. the car will be able to rev out...

Actual results may vary. :bellyroll:

ok mate i just got a set of 13" stealys from a mate and they dont fit over the brakes ha ha bitch i though some people said that they fit ... well i can tell yoiu that stock 13" stealys don't fit

not sure anyone said steelies would fit

but, as you found out, it depends on the width and offset of the wheel as it needs to fit over the caliper

i found out the hard way with some 14x5.5 daisies from a miata...

At least there are some people who actually go out and try stuff instead of just talking about it all the time.
Good to hear you tried out the 13's but yes. unfortunately steelies won't fit. The Lenso VPD's barely fit over the caliper and with that you have to put the balance weights on the inside part of the rim our the far outside where it can be seen by all. (not as nice looking but works).

If you want to know wheel and tire combos, try them out. You'll get a better idea of how and why they work the way they do. Much better than alot of technical talk that really doesn't get you to the feeling of how a tire/wheel combination works.

The Lenso's are the lightest set of wheels I have. For track they work very well. I really like this combination of the R888's for the track.

BTW the R888's are a really good tire for Tarmac rallies. If it rains. I'd recommend the R1R and probably a better overall tire choice depending on the limit of tires you are allowed to bring to certain events.

For the tight small tracks I like the 13's, but for the bigger wider radius turns, I'll use the 15's. 16's and 17's are just too big and heavy to run 225 or 245's with a stock engine.

What you guys didn't mention was the braking. On the 13's the car's brakes are more effective and you can do alot more late braking in a turn with the stock caliper setup and 13's which means higher entry and exit speeds, shorter lap times.

And please. Corrolas are no match for the Yaris. Unless it's a JGTC Corrola. That's different.

ha ha every one take note mojoyaris is a legend he can talk the talk and walk it to :) i so far have used the stock 14 no good 15" 16" 17" the best i found were the 15" luck the only once i own but then i thought hmmm it might be that i have become accustome to this size and changing wheel size can dramaticly change the handling ... ?? i a thinking about it to much ?? ha ha o an i only use my car on the road not the track ...

Kind of reminds me of Japanese cars 20+ years ago.

I have set a 14" dia BBS wheels from a Miata on my Yaris and they look great. 6" wide and 12#. With a 195/65-14 Falken 912, it should be the same weight as the 15" steel wheel and Goodyear from the manufacturer. Plenty of clearance for the brakes and strut. Hubcentric, too. For tire size info and comparison, try this link.
