A hot rubber smell from your car is almost always caused by something rubber, plastic, or oil touching a hot surface - most often a slipping belt, a melted hose against the exhaust, or a stuck brake caliper. Here is how to find the cause in your driveway.
You can usually drive short distances if no smoke is visible, but a slipping belt or sticking caliper can quickly become dangerous. Park, pop the hood, and look for the source before the next long trip.
A worn serpentine belt slips on a pulley and overheats. The friction smell is sharp and rubbery. Often paired with a squealing noise on startup or under load.
A hose has slipped off its retainer and is resting against the exhaust manifold. Pop the hood after a drive - you may see a melted spot on a hose.
A caliper that does not release drags the pad on the rotor. The wheel will be very hot and the smell is intense after stops. Often only on one corner.
A valve cover or oil pan leak dripping onto the exhaust manifold. The smell is more of an acrid oil-rubber mix. May produce visible smoke after parking.
Riding the clutch or a slipping pressure plate burns the friction material. Smell is strongest after climbing hills or pulling away from stops.
A shorted wire or overheating component melts its own insulation. Pull over - this is the most fire-risk cause on the list.

Short distances, yes - but find the cause before your next long trip. A slipping belt will eventually break and cut your power steering and alternator. A stuck caliper can warp a rotor or cause brake failure.
Mild slipping belts and small hose contact often produce smell without visible smoke. Look for glazed (shiny) belt surfaces and melted spots on hoses near the exhaust manifold.
Yes, indirectly. Low power steering fluid makes the pump work harder, which can glaze the belt and produce a hot-rubber smell. Check the power steering reservoir.
Drive home or to a shop, then stop. Continued driving can melt cooling system hoses, snap a belt, or cause brake damage that runs $500+ to fix.
A stuck caliper, a hand brake left partially on, or brake pads worn down to the backing plate. Feel each wheel after a drive - hot wheel = stuck caliper.
Brand new tires can off-gas a rubbery smell for the first 100 miles. That is normal and fades. If your tires are older and you smell rubber, it is not the tires.
