Dents and holes were anticipated, but the amount of wear appears to have accelerated in the past month or so, Erickson noted.
It appears to be correlated with driving over rougher terrain. The wheels can sustain significant damage without impairing the rovers ability to drive. However, we would like to understand the impact that this terrain type has on the wheels, to help with planning future drives.
The team is now inspecting the new imagery acquired of the wheels and will decide if a course alteration is in order.
Routes to future destinations for the mission may be charted to lessen the amount of travel over such rough terrain, compared to smoother ground nearby, says NASA.

I don’t guess there is a Discount Tire nearby.
Say that 3 times fast.
Can’t say it one time fast!
I wonder if they bought the road hazard insurance?
Seems to me that if this thing has only traveled a few miles at a snail’s pace and the wheels are already banged up, the design was poor and the wheels were never tested on earth.
You’d think that with gravity only 38% that of earth, it wouldn’t do much damage.
Should have sent a monster truck. What were they thinking?
Besides to go all that way and not be able to mudhog if you found water is just crazy!
Hasn’t the Rover already lasted WAY beyond its design specs?
Just floor it babeeee! Pedal to the metal and fly over those rocks. That’s what my youngest stepdaughter would do.
BTW, UPS delivers to my remote area (much like Mars, climate-wise and road-wise), although FedEx doesn’t.
And you say that because?
Sorry was thinking of Spirit. This is Curiousity. Getting there though.
I don’t think so. I think it intended from the start to climb mt sharp
That ripping is strange. I wonder how thick the wheels are.
It looks like it might be a materials failure.
Made in China?
Next thing you know a Martian will Key the paint.
If they go to Les Schwab, they’ll get a free cut of beef.
All that damage in only 3 miles? At this rate they will be damaged beyond functionality before they get to 10 miles.
Bleeping idiots didn’t renew their AAA membership. What do they expect?
Too much durability was sacrificed over weight.
They lasted a lot longer than anyone thought they would
Rumors abound that there are things near or on that mountain that are not exactly “natural”, ya know?
Of course now they have a pretty dependable excuse “Well, you know we’d love to go closer over there and take a better look at that thing that looks like an ATM/Cash machine.... but the wheels... the wheels...”
The extreme cold temperature there also couldn’t help matters.
That that that
They need to send up an extra large 3D printer and a Canadian remote manipulator arm.
Yup. I confused my Rovers.
Turned out the video from that trip was somehow “lost”.
Good luck finding that story today. Internet searches only bring up rafts of repetitive and spurious websites which sound similar but are either unrelated or totally bogus.
I bet that they would have shredded much sooner.
I can’t believe they didn’t bolt a spare on to the back of that contraption.
Drive it like you stole it.
“BTW, UPS delivers to my remote area (much like Mars, climate-wise and road-wise), although FedEx doesnt.”
You too, eh. UPS has delivering to the ranch for 30 years but Fed Ex, to this day, doesn’t deliver within 30 miles of the place.
I don't remember exactly but they were designed to move the lunar rover and they performed their job well. How well they would have done on Mars I don't know but they weren't designed for such conditions.
They’ll have to wait ‘til February!
What did they find in the crater allegedly?
The wear really got worse when Sheila Jackson-Lee sat on the Rover.

According to this wiki...
Curiosity was launched from Cape Canaveral on November 26, 2011, at 10:02 EST aboard the MSL spacecraft and successfully landed on Aeolis Palus in Gale Crater on Mars on August 6, 2012, 05:17 UTC. The Bradbury Landing site was less than 2.4 km (1.5 mi) from the center of the rover’s touchdown target after a 563,000,000 km (350,000,000 mi) journey.
The rover’s goals include: investigation of the Martian climate and geology; assessment of whether the selected field site inside Gale Crater has ever offered environmental conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for future human exploration.
Curiosity’s design will serve as the basis for a planned Mars 2020 rover mission. In December 2012, Curiosity’s two-year mission was extended indefinitely.
In April and early May 2013, Curiosity went into an autonomous operation mode for approximately 25 days during EarthMars solar conjunction. During this time, the rover continued to monitor atmospheric and radiation data, but did not move on the Martian surface.
Mobility systems: Curiosity is equipped with six 50 cm (20 in) diameter wheels in a rocker-bogie suspension. The suspension system also served as landing gear for the vehicle, unlike its smaller predecessors. Each wheel has cleats and is independently actuated and geared, providing for climbing in soft sand and scrambling over rocks. Each front and rear wheel can be independently steered, allowing the vehicle to turn in place as well as execute arcing turns. Each wheel has a pattern that helps it maintain traction but also leaves patterned tracks in the sandy surface of Mars. That pattern is used by on-board cameras to judge the distance traveled. The pattern itself is Morse code for “JPL” (·-— ·—· ·-··). The rover is capable of climbing sand dunes with slopes up to 12.5 degrees. Based on the center of mass, the vehicle can withstand a tilt of at least 50 degrees in any direction without overturning, but automatic sensors will limit the rover from exceeding 30-degree tilts.
Curiosity can roll over obstacles approaching 65 cm (26 in) in height, and it has a ground clearance of 60 cm (24 in). Based on variables including power levels, terrain difficulty, slippage and visibility, the maximum terrain-traverse speed is estimated to be 200 m (660 ft) per day by automatic navigation. The rover landed about 10 km (6.2 mi) from the base of Mount Sharp, and it is expected to traverse a minimum of 19 km (12 mi) during its primary two-year mission. It can travel up to 90 metres (300 ft) per hour but average speed is about 30 metres (98 ft) per hour.
Curiosity is 2.9 m (9.5 ft) long by 2.7 m (8.9 ft) wide by 2.2 m (7.2 ft) in height, larger than Mars Exploration Rovers, which are 1.5 m (4.9 ft) long and have a mass of 174 kg (380 lb) including 6.8 kg (15 lb) of scientific instruments.
That is not a rip. The rover squashed a road runner!
Well, those Hasselblad cameras they used were some of the finest photo technology in the history of mankind.
For years I (and you, I’m sure) heard stories about things being covered up. I tended to think yeah, well, maybe, etc etc etc
But after looking at a large number of photos from the lunar missions, including photos taken by the orbiters, as well as Clementine photos, etc, you have to come to one conclusion:
Many, many of them show obvious signs of tampering.
The question then becomes who and why!
IIRC it was claimed to be one of two or three wacky things.
One was that they were there to secretly bury some cosmonaut’s who had crash landed on the moon.
Another was an alien ufo base or something like that.

Avoid angering alliterative Mars!
