Yeah, I am actually new to the import scene. I came from the domestic world. Is this becoming popular to decrease in the wheel size? As from my personal experience many people are going larger and wider wheels.

Small diameter wheels are almost always lighter when comparing same width. Rubber & air is lighter/less dense than aluminum. IMO, Wheels only need to be large enough to clear the brakes.

Big wheels are just for 'peacocking' ...

Couple things.


1-That rubber is often lined with steel belts and performance tires are quite often heavier than the performance wheels they go on to.


2-For most people it is for strutting, but at a certain application and power point, big wheels are advantageous or even necessary.

Can agree with that.

Here's my take. I run mine with "regular" (surprisingly grippy) soft sidewalled 16" tires now. Oh yes indeed there is more movement, but I realised that I actually like that, it makes it more fun to play with weight transfer. Even if steering is less sharp, there is a lot of grip feedback. Once you really start sliding, it's not as progressive as a stiff tyre though. But because of the extra movement, you know what's happening anyway.

Thing is, our cars show their talent and are enjoyable with almost any tyre. And soft doesn't mean bad. Relative to a soft tyre, the suspension with springs, dampers and bushes, and the body also, become stiffer. For a given harshness of your ride straight on: would you rather have soft tires on a stiff body and suspension on a twisty road, or superstiff tires on a sloppy suspension and body?? This is often forgotten, and why people start with stiff low profile tires and end up with full suspension and bracing mods and wonder how their car got so harsh... (and how their wallet got so light )

As such, to keep that ratio as good as possible, I still have subframe inserts, steering rack bushes and a front strut brace on my soft tires.

And as you already know, similar things happen when the wheel is light. Wheel forces become lower and again suspension and body are better equipped to keep ground contact. My soft tyre weight is 7,2kg, rim 5,3kg = wheel 12,5kg. That's 26,5lbs for you guys. For the whole wheel, not just the rim or tyre.

Most obvious in daily driving, ride is much better. What can I say, mine is a DD. And on bad twisty roads together with excellent wheel control as described above, that also means a lot more fluid drive and, uh oh, dare I claim so, faster!?! Or most important for me, very enjoyable

All depends on what you want from your car... And sometimes less is more.

The steel belts (woven strands) are still lighter than the aluminum (solid). I've dropped from 'Extreme Performance' summer tires on 18" wheels down to studless snow tires on 16" wheels and been 10 lbs lighter per wheel. I know that's not a 100% fair comparison, but even a gravel rally tire on the same 16" wheel resulted in 5 lbs less per wheel than the 18" setup.

As with any car modification, its all about what the owner wants from the change...

Just for the sake of debate (educate me), why would someone on stock brakes get a benefit from a set of 18x8" wheels over a set of 17x8" wheels? I know that a car with 50% more power than stock usually needs bigger brakes, which can make bigger wheels necessary, but any car at near stock power w/stock brakes? Why would bigger wheels benefit them?

Does anyone know the OEM 16" tire brand? I know it's 205/55R16, but aside from that?

You can look up tire weights on tire rack and you'll see steel in tires can easily outpace aluminum in wheels especially once you get to 18". Just check out how heavy Bridgestone REs are.


18x8 offers a larger contact patch than 17x8 based on the trigonometry of the extra radius. Whether that gets you shorter or longer distances is a question of balance with the rest of the car. Traction wise, 18s get you more potential grip from more surface area. I say that as someone that prefers small light wheels so I'm not into Dubs.

Not quite true if your overall diameter is the same.
