run flat tires?

The car is able to tell if there is a flat tire by comparing the rotation of each wheel at a given speed. The light usually goes on once after I switch wheels during spring or fall.

The manual states you can drive at 80km/h when there is a flat.

The ride is definitely very harsh! Although very convenient when a flat happens on the highway, I would rather have a spare than run-flat tires since we have so many potholes here in Quebec.

Thanks paco for confirming what I said above .
Also, I believe that it is a legal requirement for a car to carry a spare tire, except if the tires are run flat tires. So you are right paco, if you do not have run flat tires, you need to have a spare tire.

It's not a legal requirement, or else BMW and Merc's are breaking the law. Some of these vehicles don't have spares. I think same with Porsche.

Nope. The Mazda RX-8 does not include run-flats and has no spare unless you order it as an option. A lot of manufacturers are starting to just include a patch kit.

All vehicles sold with runflats are (were) required to have a TPMS. If the tire gets punctured the light on the dash goes on when it detects pressure loss. That was at least until 2008, when all cars were required to have TPMS no matter what type of tire they had.
