I plan to get this VOSSEN - VVS-CV1 wheels on my Sienna, crazy? I know. :D


vossen-vvs-cv1-4.jpg




Would all minivans work with two 20" diameter (20x9.0) in front and two 20" (20x10.5) in rear without doing any customization? :hmm:
 
no idea. you may have to do melt mod (or not)
 
What is the purpose for changing the wheels? Are you pimping a minivan?

Make sure its similar radius tires as stock so it doesnt rub the wheel wells if ur gonna drop it down. Also make sure its not too wide either.

Also narrow tires in front and wider in rear wouldnt be a good idea cuz it would be difficult to rotate tires of same size.

yeah, very true, but i would involve modding 2011 sienna competition and get prizes in cash so i can afford new tires every 20k miles lol

You can try www.tires.com to do the rim/tire size that will fit without mods. I think you also can look up how much difference in radius on special online calculators too.

it's so..... Californian of them to do such silly thing to their cars :roll:

Total agree with you.....more rubbing the areas like you says wheel wells... the front struts where the oversize or wider (maybe offset rims?) tires can rub the bottom of the cup ( support the coil spring end).
If you want the 20 inch rims, then original Sienna tire diameter and wide should be remain same. I think they are ok but make sure the 20 inch rims have the correct offsets (negative or positive offset) to match your Sienna.

Also different size cause error MPH and probably poor fuel economy.
 
MPG decrease should not be drastic. Theoretically speaking, he would probably lose 1-2 miles per every 1inch to wheel size gained. Tires are more important, the revolutions per min is what calculates mpg loss.

Example, Cooper Tire Starfire SF340 Tire from Market Tire Company
Cooper Starfire SF30
16" and 17" calculation
16" revs per mile (cooper site info) = 777
17" rev per mile = 759

777 - 759 = 18 rev difference, 18/777 = 2.32% difference

Assume he gets 300 miles per trip on 17". 300 * 1.0232% = 306.96 miles on 16"
Finally, to get mpg, I don't know sienna's tank size, but I assume 19.5 gal like some toyotas.
17" 300mi / 19.5 gal = 15.38 mpg
16" 306.96mi / 19.5 gal = 15.74 mpg

difference % is still 2.32 (constant). Real world will differ, but this is theoretical calculation not factoring driving habits, just tire/wheel size and revolutions per mile alone.
 
search it up for real results, yeah, it's similar. :P

Hmmm base tire and steel rims makes car accelerate faster and gets better mpg than expensive wheels. Im not surprised about the results lol. However performance tires gives better cornering handling and better braking results.

eh..... not really. it's extremely minuscule.

what can really cause poor fuel economy is bad driving habit and under-inflated tires. and of course.... living on hilly area like S.F.

that's what melt mod is for.

true but... a lot of sport cars are narrow in front and wide in back like my parents' BMW.

I never said BIG. Just cause error MPH and poor fuel economy. That's it.

So you see a picture 15" got 23 MPG and 19" got 21 MPG and 3 MPH error which true that what I talked about. 1" different is hard to noticed but 5" or more get noticed so easy.

I drove customers's Vortec 5.3L V8 *very popular from here* with 18" wheels like thousand times already till I drove same truck with Vortec 5.3L V8 with 30" wheels and it feels like v6 due poor torque. My experience is real world.
 
I changed the gearing when I changed the overal tire diameter.
