Do heavier wheels cause problems?

My wife got a '13 Sahara unlimited. It had the new 18" bright silver painted aluminum wheels. I thought they looked very nice. Anyway she wanted black wheels and found some V-rock Recon wheels. They look nice but damn, they are heavy. I didn't weigh them but I would guess they are 10 -15lbs heavier than each jeep wheel.

I know it is rotational weight and once they are spun up it will be probably be a negligible drag on fuel economy and brakes. Anything else that might be a problem? Four wheel drivetrain?

Some will tell you that the added weight increases the chance of breakage and will wear parts out more quickly but I have not seen anything to substantiate those claims.

I generally run the heavier steel wheels and have had no problems with accelerated wear on parts or breakage.

Added weight DOES increase the chance of breakage and wear, but no wheel can be THAT much heavier for it to be a very significant increase. Here's some fun reading if you're the type of person that likes to know things--http://hpwizard.com/rotational-inertia.html

Thanks guys. Jeep says these wheels retail for $600/ea. I think I'm going to ask 350/ea. they were only on about two weeks and are in excellent condition.
Is that too much for used wheels?

It matters for rotational mass (gas mileage, acceleration, braking) and for unsprung weight (ride quality).

The lighter the wheels and tires the better.

Aluminum is the way to go, IMO. Aluminum can be black (anodized or painted).

Also, a 16" wheel is signifigantly lighter than a 17" wheel.

A 15" wheel is signifigantly lighter than a 16" wheel.

A 7" wide wheel is signifigantly lighter than an 8" wide wheel.

A load C tire is signifigantly lighter than D or E.
C also ride much nicer. C are plenty tough enough for off road on a 1/4 ton Jeep.

AT are usually lighter than MT. AT have less rolling resistance than MT.
