Reading an ad for the new Jeep,
and one of the selling features listed,
( besides more cupholders ) was 18" wheels.

I notice a trend toward bigger wheels in many cars.
Any advantage to these things,
besides costing more at replacement time.

ground clearance, longer tire life

Longer tire life? What?
Doesn't matter what size tire you buy.
The tread wear rating will be on the tire.
Tire life is based on rubber hardness and how deep the grooves in the tread
are.

The only advantage is better looks and slightly better handling.

The same rubber on a larger diameter tire is going to last longer than the
same rubber on a smaller diameter tire. Simple mathematics. Yes, profile
comes into play in addition to rim size, but the more circumference, the
more distance per revolution.

Larger brakes can be fitted as well.

Most of the tires aren't greater circumference though, just lower profile. I
think it's done mostly for looks, a truck for instance wouldn't benefit
handling-wise from low profile rubber, and raises potential for curb damage.
Give me back my 16in that were less money to replace.

Bigger rims have advantages - WITHIN REASON!!:

-More feedback from the road.
-Today's suspensions do most of the job that suspensions of 30 - 50
years ago shared with shock-numbing high-profile tires that rode on
13" or 14" rims.
-Wider profiles track straighter - though this is negligible compared
to designing in enough SAI and appropriate amount of caster into the
vehicle.

Now for the "WITHIN REASON" part:

20" - 30" wheels belong on horse driven vehicles - if you catch my
drift. Do the math:

P400/30VR25 = Pure Bling....'nuff said.
