Car options: Value added, or not

The right options make your car safer and more valuable. The wrong ones just make it more expensive.

Run-flat tires
Nobody loves changing a flat tire, but some hate it more than others. If you fall into the latter camp, run-flats may be a good buy.

Offered on cars from the Mini Cooper to the Rolls-Royce Phantom, run-flat tires let you drive up to 100 miles at 50 mph even if a tire has lost all its air. There's no spare in the trunk (which can give you more space for your gear) and you'll never have to crouch on the side of a highway at 11:30 p.m.

That said, run-flats can cost as much as 50 percent more than regular tires (it's a roughly $400 option on most cars), not every tire shop is certified to handle maintenance and getting a run-flat patched after a blowout can cost upwards of $50 - twice the price of a standard patch job.

The Verdict: It comes down to how often you expect you'll change a tire and whether you'd pay around $400 to avoid it.
