Rotiform possibility?

[SilverSquash!]

I wanted to know if either of these sets of rims will rub?
I drive with 3 adult passengers daily. I dont want the wheels to protrude from the arches.
Also, how big of a difference does 17 inches have on fuel economy? I get normally around 600km per tank.

Idk even know rotiform made anything narrower than 8". In the 8" +30 if you run a stretch like 19 5/40 you could potentially get away with no rubbing but it will be close. I just finished running 17x10 +25 and the rubbing was actually pretty subtle to non existsnt on most commutes but I have a ton of fender rolling pulling and trimming done so you may need a little yourself. Are you dropped or do you plan on dropping and what suspension? That will make a lot of difference.

You'll need to roll your fenders if you don't want any rubbing (shouldn't be that bad to begin with).

As for gas mileage, you'll definitely lose a lot in the city, but you'll pick up mpg on the freeway. With all of my 17's (that were heavier than the steel rims and tires), I get low 40's to mid 50's (sometimes touching high 50's to low 60's) on the freeway. But as soon as I drive in the city, I'll get 20's to 30's mpg.

I do almost all stop and go and my average tank MPG went from 35-37 down to ~31

You must have super heavy rims. lol. The 20's to 30's instant mpg I see if I do all city driving usually comes out to be ~34 mpg tank average, give or take 2 mpg.

My tire and VS-XX come out to be 43.5 lbs, front and rear set ups.

My wheels were 22 lbs each iirc +215/40/17s lol that is heavy

Never had the opportunity to weigh the VS-XX naked :laugh:

Don't think they're 22 lbs tho. hahaha

[SilverSquash!]

thanks for all the input people.
Im still stuck between two worlds because i want a neat look and if i put the 17's i wont do suspension mods, because it will look low and hence only rolling the fenders will be done. But if i go with 15's im going to have to put shortened shocks and lower springs for the same look.
i need to do at least 600km per tank and am still stuck between the two options.
I really like the rotiform design however they dont come in anything smaller than 17" and also they are replica's hence the 7.5J.

all the advice is much appreciated!

I would still lower it with 17s

[Kaotic Lazagna]

17's alone won't make the car look lower. It will still have that massive OEM wheel gap. I vote the same as 1.5, lower it still.

It won't actually look much lower (because the car isn't lowered), wheel gap depends on tire profile too, and you won't need to roll the fenders unless you lower the car.

What a 17 DOES do is fill the wheel well with more wheel and less tire. A lot of people like that look -- it's a personal choice.

But if i go with 15's im going to have to put shortened shocks and lower springs for the same look.

There are no shortened shocks, unless you upgrade to coilovers.

Not sure what this means. If the outside diameter with tire is the same, wheel size is not relevant.

Rotiforms are custom made, I've seen them done in all sizes. I am a dealer for the brand.

[1.5]

Everytime Ive been to their website I see their custom wheels only start at 18" and go up

"Available in diameters from 18" - 24" with pricing starting at $1,250 per wheel"

[B2FiNiTY]

it's gonna rub, and definitely not the setup for you since you are going to carry multiple passengers.

[SilverSquash!]

Thanks for the input people, im taking all the advice i can get.

600km- i need to get at least 560-600kilometers per tank when i fill up, so fuel economy is a factor.

3 people in total travel in my lift club so 2 and a half adults lol.

i want to fill the arches coz theres too much space lol

if im not mistaken shortened shocks are shorter than the regular shocks and is advised when putting in lowering springs, we have monroe, gabriel and koni to name a few that offer shortened shocks here.

rotiforms website does start with 18" but they also said they can custom make anything because they can lol. note im getting the replica's

I know what they are. I'd like to see those specifically made for the Yaris. Links would be appreciated. You don't need shortened shocks with any of the springs I offer from my shop. Lots of people on here will agree.

[why?]

If gas mileage is a factor don't get 17's. Find the lightest wheel you like or can afford.

with a thin tire

[SilverSquash!]

Okay I think Im going to leave the shocks and just drop with a set of new springs

Now that that's out of the way, I really love those roti's i think im going to borrow my friends set if he still has them and check the fuel economy and if my car can make it to campus and back 5 days a weak (roughly 500km) then Ill get them, thanks for all the help guys.

By the way 1.5, is there a benefit of a thin tire for fuel economy? i know it helps the car to grip and corner better..i think?? And thanks why? i will get a rim i can afford lol even if it takes time to save up. :D

[cali yaris]

Weight is most important, and a high treadwear rating usually equates to better fuel economy.

I am a dealer for Rotiform (we know the owner pretty well), let me know if I can provide a quote -- we have very competitive shipping rates.

[mr_miles]

You just said the magic words! Now I know who to go to when I have enough saved up for a set.

A thinner tire would provide less grip/friction than the same tire in a wider size and because there is less friction, less torque is required to move it against the ground.

Also keep the tire inflated to a high pressure to help fuel economy.
