o I don't get it. What is the purpose of the trend towards larger wheels on small lightweight cars made for acceleration and not top end speed (like the ND)?

Pros for bigger wheels on samll lightweight cars:
>looks (opinion)
>better tire selection (being shilled by more popular heavy ass can't turns)
>cheaper to produce than smaller WIDER wheels with similar tire widths /205-225/ and aspect ratio /45/ (fine)
>big brake kits (really?? Just buy better pads and maybe pistons/rotors)
>better top end (don't need it)
>quicker to stop because wheels are heavier (making the car heavier? Again better pads or pistons)

Cons:
>WAY slower acceleration
>WAY slower to steering inputs, especially countersteer
>WAY less grip at lower speeds/transitions (treads are optimized for higher speeds on larger wheels)
>Heavier, more unsprung weight
>More rotational mass (means need more power to rotate even if lighter)
>Cost more of everything $$

Why o why o

>tfw want an ND on 15s, hot damn

>quicker to stop because wheels are heavier (making the car heavier? Again better pads or pistons)
No, that's backwards. Heavier wheels = much slower to stop. It's one of the biggest things that affects your stopping distance actually.

what
are you talking about stanced show cars?

are you talking about normies that just buy any wheels they like?

did you literally just start a thread to sperg over others personal preferences?

how could you care

It was already shown that heavier wheels decrease braking distance

The trend of manufacturers moving all performance/sports cars to larger wheels (on small/light cars unnecessarily)

Huh, I never would have thought it.

It might just be the aspect ratio with less tire deformation

I could be wrong

>half your reasons for why bigger wheels are bad are flat out incorrect

Which ones btw?
>>
>>14198543
I like how you argue against all the pros but not the cons lol.
Anyway the reason is cosmetic.
Modern cars need to be designed around big wheels to disguise the bulkiness caused by crumple zones.
Personally I think the ND looks better on smaller wheels. The factory 17s are too big.

if it makes you feel better, on reflection i deeply regret making that post

reasons to use larger wheels

- better tires (can be hard to find certain sizes for 15" or smaller wheels nowadays)
- bigger brake rotors
- because it looks cool
>>
>>14198741
>WAY slower acceleration
it's not WAY slower, especially if you stick to the stock overall diameter. I'm not convinced that there is a difference.

>WAY slower to steering inputs, especially countersteer
just no. wheel diameter is not going to make your steering inputs slow and numb. with shorter, stiffer sidewalls you'll have more steering feel, not less

>WAY less grip at lower speeds/transitions (treads are optimized for higher speeds on larger wheels)
WAY less grip? really? where is your proof for these claims anyway?

>Heavier, more unsprung weight
this one I'll give you. even so, the increase in weight isn't that much, as shown here >>14198583

>More rotational mass (means need more power to rotate even if lighter)
this is negligible as long as you don't go overboard. tires have mass too you know.

>Cost more of everything $$
I guess. cars aren't cheap no matter what.

in my opinion, oem wheel size is good. OEM +1 is about the maximum diameter you should go. but downsizing your wheels is just weird. you restrict your tire choices, restrict future brake upgrades (big brake kits are always going to be better at dissipating heat that just pads and rotors) and look bad. you also add sidewall flex and reduce braking ability as shown here >>14198583
>>
>>14198829
smaller wheels can make a full rotation in less time than a larger wheel, common knowledge acceleration is better

The larger the wheel the smaller the turning radius. As such your rack and pinion are configured to be slower since there is less of a radius for turning.

If you notice, tires have a full tread design that gets repeated from section to section on the tire. Optimal section to road coverage is reached faster on smaller wheels because the rotation is smaller.

more rotational mass means it takes more power from the engine to turn the wheel regardless of weight

> in my opinion, oem wheel size is good. OEM +1 is about the maximum diameter you should go.

depends on the car
stock SW20s come with 14 or 15 inch wheels
>>
>>14198543
You know engineers spend years designing a car. Specifically the wheels that will go on it.
They take into account shit you never even know existed, such as scrub radius, axis alignment, wheel squirm, etc.

All these plebs that change out their wheels, or install spacers and completely fuck with their tire center causing their shit to toe out under braking.
>>
>>14198786
>what is contact patch
Of constant area with constant pressure.

>>14199008
This implies everything that comes out of factory is perfect.

This

It still amazes everytime I go on any forum, and the first thing people want to do is stick 245's on their shitbox, and everytime you ask them why they say "because all the fastest people use it"

Just WTF? That post is seriously retarded.

>>14199045
this.
>>
>>14199064
Are you so sure?

I bet you also think ABS is faster to stop than non-ABS because "computers" and "technological innovation"

We almost made it with this damn car, but still so much to change . .
>>
>>14199106
nigga the ND is great the way it is. have you even driven one?
>>
>>14199106
ABS is shit now yeah, because car tires back in the day had the contact patch of a bicycle and the cars suffered massive amounts of weight shift due to their ungainly design.

But what does that have to do with anything in your previous post regarding moment of inertia and large wheels being shit.

sorry, not every car manufacturer has a GM mindset.
>>
>>14198583
Hmm, let's see here.

This shows that heavier wheels decreases stopping distance, yes.

But this also shows wider contact patches also increases stopping distances.

Nice try, pal.

As long as they are lighter then that's good

Still your tires will end up making it heavier
>>
Most of it has to do with consumer demand. The most significant portion of consumers want larger diameter wheels so car manufacturers cater to them. Tire manufacturers drive the decision too. Apart from 225ish or narrower tires, it's almost impossible to get wide street tires under 17-19" wheel diameters.
