Unfortunately, they do. In some rural areas of the world, it is very common to see individuals walking across active runways. Occassionally, the inevitable does occur and the mess on the aircraft tires is horrific. Notice the individual third from the left in this picture:
This individual has many bad habits and has been generally known as a creep for many years. Just moments after this photo was taken, he was mauled by an A320 - resulting in creep marks on the landing gear. Hope this helps.

Very amusing, guys. Airliner tires do not generally have creep marks because they don't have inner tubes. Creep marks are lines painted across the junction of the wheel and tire to show if the tire has moved on the wheel. If this happens with a tube tire, it's likely that the tube has folded.
The primary function of the design engineer is to make things difficult for the manufacturer and impossible for the AME.

Years ago, TWA international flight crews numbered the wheels according to how many crewmembers there were on board. After landing and parking at the gate, the number that was at 6 o'clock won the pot. Usual amount was $1.00 per crewmember.

We called that "Taxi Roulette", but ours was more like actual roulette that what's described above. The bosses for the brake keys on the inboard half of the nose wheel (same wheel assembly for nose and main wheels on the CH-53E) would be numbered, 1 to 16 IIRC, and we'd each throw in a buck for however many numbers we wanted. Usually 4 crew, 4 numbers each; the lucky one walked from the aircraft $16 richer...
Oh, and on-topic - we had slippage marks on our tires & wheels, and they were tubeless.
Isn't creep also a form of Metal fatigue and/or corrosion?
Defination of Creep :- The flow or plastic deformation of metals held for long periods of time at stresses lower than the normal yield strength. The effect is particularly important if the temperature of stressing is above the recrystallization temperature of the metal.

I thought so, when boroscoping the Nozzle Guide Vanes i remember seeing to check for Creep...
