Newbies - Let's See Some Pics!

You're absolutely right! I think the colour I was referring to in my post was actually "Silver Pine Mica" (very pretty but a bit different to "Sea Glass") - I'm impressed by Sea Glass, but I'm still glad I bought the Magnetic Gray ChuggyPig (still waiting for the new reg. plates) - Wil

 

Actually I have read that somewhere. I think it was something about men can't see as many color/shade variations as women.


iPhone ?

 

It is pretty, that was my second choice. My first was Blizzard Pearl and that's what I got.

Hi everyone! Here's mine, Blizzard Pearl 2014 Prius Three package. Her name is Sam, short for Samantha Micelli (Alyssa Milano's character from who's the boss haha ).

In college years ago I owned a CRX (which I tuned up a little bit), so of course the tuning bug in me is itching ! Looking to add some lightweight 16s or 17s and lower it a bit to start.

With that said, can any of you owners with bigger wheel packages share what your MPG results are now compared to when you had the stock alloys on? Thanks and glad to be a part of the Prius Family.

Regards,
Ram

 

Larger diameter wheels = lower MPG.

 

Sorry if I seem stupid, but please explain just how that works... ...thanks!

DROID4 ?

 

...from Toyota europe document. Notice urban/city mpg value differences between 15" and 17" wheels:

 

...but I winner if that is measured or calculated, and if the latter what formula was used...

DROID4 ?

 

I have no idea, but *if* europe MPG numbers are determined like our EPA numbers are, they were done via dynamometer testing, not by equations.

 

...but the physics indicate that larger diameter wheels would mean higher (better) mpg. ...and to quote Scottie, "...ye canna change the Laws of Physics! Jim! ...ye ken?

DROID4 ?

 

IMHO - IF / WHEN the drivetrain has been 'optimized' for 15" rims, moving to 17" rims ain't gonna be optimal anymore.

One would think that bigger wheels would equate to better mpg at highway speeds. I could see where they would suck that fuel from a dig.

If bigger wheels = better gas mileage then all these guys driving around town with their gigantic wheels under their M&M, Aquafina, Gushers cars are onto something.

I don't see how the physics of bigger wheels = better mpg.

 

Simple geometry - (hint:look up how the circumference of a wheel is related to its diameter). Also, I think your note might be referring to "their gigantic wheels", meaning their gigantic wheels with low-profile tyres, so that the overall diameter (including the tyre) isn't much different to that of a regular wheel/tyre combination.

 

Inertia

 

You're not factoring in weight. Particularly might want to look into the term "unsprung weight" in relation to automobiles. What it means is, any added weight not supported by the suspension i.e. tires & wheels will drastically affect MPG in a negative way. Not to mention, sitting higher up makes your car less aerodynamic. There's also other things affecting it that I haven't even got into but not worth noting. Only thing you should know is this: bigger tires/wheels will decrease fuel economy. I think you might be trolling though, this is really like car knowledge 101.

 

Here is a picture of my 2014 Prius. I'm new to this forum, but have been racing and building cars most of my life.

 

Very nice! ...does it have a name yet?
