I have less than 2,000 miles (mainly highway, all on pavement). I washed the truck and windshield today, and noticed several rock pits on the glass already (not deep enough to star/crack). I was hoping it was just something stuck on the glass, but unfortunately it is real pitting. I was hoping that the flatter angle would mean less direct hits from small rocks, and the "gorilla" glass would be tough. But it appears no better, and possibly worse, than my Model S and previous Jeep Grand Cherokee. Once snow season starts and they start salting/sanding the roads, I'm afraid this is going to get real ugly. Only bummer with the truck so far. Otherwise we love the truck and I never thought a pickup would be my preferred daily driver. So much more comfortable and smoother on the road than our S, X, 3, and Y. I'm also very happy with the efficiency of my Dual Motor. Driving is 95% highway between 70-75mph and I'm now getting under 370Wh/mi on the stock wheels/tires (340-350 mile range). I guess that is an advantage of living at higher altitude.

What is your cold tire PSI and how much pressure rise are you seeing on the center display after extended highway driving?

I've noticed these tires (AT) return a lot better efficiency just a bit above 50 PSI cold (indicated 55 psi warm). I ran 45 PSI for about 100 miles and the hit to efficiency per mile was rather dramatic. I could even feel the truck didn't roll as easily.

I saw one tiny pit from a rock impact when I was cleaning my windshield today, but I drive a lot of gravel/dirt roads so that comes with the territory.

Random damage doesn't mean it's worse. It just means it broke for you.

The harder glass will resist pitting, but it can't resist everything.

But is there any evidence the glass harder or better than any other car’s glass? Or do we just believe the steel ball BS means it’s tough? Just sold my Jeep with gorilla glass and near vertical windshield, no chips after 20k miles. Best windshield ever. Hoped CT would be like this… nope, same problem as my other Teslas. I have at least 2-3 small chips that IMO shouldn’t there if the “tough glass” story was true. Not the end of the world, still love the truck, but this was a big disappointment for me and I no longer believe this glass is anything special. I would pay $1k extra for gorilla glass if it was an option.

I'm at 50 psi on the tires. You set them when cold.

We have no claims from Tesla as to how the glass on the Cybertruck handles pitting, the idea was to reduce fleet downtime due to cracking and glass replacement (same as on the Tesla Semi). This can save fleet owners a lot of money and improve logistics with fewer trucks out of service at any given time.

I recall that Elon commented that the glass used in the windshield of the Cybertruck is more resistant to propogating cracks from impact strikes. Yes, rocks will still strike the windshield and leave a tiny impact crater, but it's suposed to be more resistant than regular windshields to turning into radiating cracks requiring a windshield replacement.

And there is nothing BS about throwing a steel ball at auto glass.

3,000 miles on CT and no bug splats at all!
By the way, what is the last thing that goes through the mind of a bug before it hits the bug covered front facia on a CT?

It's butt!

At 15k doing fine. I think more of the question will be the front camera. I have pitting on that. At 50k it should be interesting the view from it. Is that a wear and tear item? Shouldn't it work and not be cloudy at 50k? Or is it like a tire and needs to be replaced?

Windshield is above average compared to other Tesla's for miles. If one expects boulders to bounce off. Maybe in Mars they might.

I was asking you what your display reads after you've been on the highway for 30-60 minutes. I'm just curious how much pressure rise you get out of them.
I will try to remember to notice.

I live in Montana where there is always sand or gravel on the road. The area here is so hard on windhields so I had a protective film put on the outside on my windshield. Cost me 700.00 but i thought that might be cheaper than a new one and finding someone to replace it.

What did you put on? I didn't think that was an option for windshields.
