There are a lot of manhole covers on the first section of my drive to work, and I commknly see people swerving all over the road just so their tires won't touch them, even jeeps. Why?

My favorite people are those who drive giant SUVs with huge tires lifted way off the ground who do this and also slow down to 2MPH to go over train tracks.

Because it feels horrible to drive over and if they're bad enough you can crack your rim on them

In my city, they just keep paving over the old asphalt, so the manhole covers are like 6 inches deep in some places. Hitting one of those in my sedan is not pleasant.

At least up north around where I live manhole covers are often also either holes or bumps in the road due to things shifting around from the freeze/thaw cycles. Basically potholes with a purpose. Hitting bumps is bad for your car, so that's a pretty good reason to avoid them. Though I'd never swerve around a bump if I was going to come close to someone else, since that's much more dangerous.

And here I am with my 20 year old little truck and don't slow down for anything.

I was about to comment just right this.

In addition to frequently being a dip in the road, there are two on my way to work that make a clunking noise when I go over them and I don't like it. This has lead to a habit where I just avoid them in general.

I don't expect them to fail, it is just the noise and bumping feeling.

As others have said, it's just not great for the car. Will it damage it if you hit one? Probably not. But if it's your work route or other commonly taken route, you're gonna hit it 260x in a year, and you'll own the car for multiple years. It adds up quick. Plus, they aren't always smooth to the ground or free of other pot holes and square edges. If you hit it hard enough or if it's too sharp, jagged, or deep, you can damage the wheel, the suspension, and the tire itself, easily in the thousands of dollars to repair, along with not having a vehicle for up to a few weeks.

Don't get me wrong, they shouldn't really be swerving all over the road, but dodging em when you can is nice.

I find the name manhole to be sexist and I prefer the term personhole.

Your tire usually drops into them and this shortens the lifespan of struts, ball joints, sway bar links, control arm bushings, and potentially throws off your alignment.

I drive a Honda fit and don't baby my tires like these people. Tires that are way smaller and an undercarriage way closer to the ground. Not a vehicle made for bumps like an SUV is. I have never, not once, had to replace my tires from damage other than a piece of debris that got picked up like a nail dropped in the road. I'm on my second Honda Fit as well so I've been driving them for some time.

If SUVs are losing tires to train track they are so insanely overpriced. Their car payments are more than a set of my tires.

I drive a small car with stiff (sport) suspension. In my area manhole covers typically aren't aligned well with the road surface making them quite bumpy to drive over. This can jarring and even painful for me due to medical issues that I don't care to get into here. So I routinely avoid driving over manhole covers.

Why the fuck do people on lemmy intentionally misquote people to make their points?

Do you really think people can't just read my comment? Or did you just not comprehend what I actually wrote?

If going over manhole covers or train tracks too fast caused tire damage it would have happened to my cars by now. I've been driving for over 24 years.

I know which ones near me are bad.

The funny part is that going slower makes the bump worse. Your shocks need to compress to work.

The forces on your suspension can be tremendous. Repeated impacts cause faster wear. Large impacts can cause immediate damage and/or loss of control. The popularity of large wheels means the capacity of the tyres to absorb an impact is reduced, and even with larger sidewalks, tyres can be damaged by impacting a sharp edge. A single OEM rim can cost over $1000; a suspension repair is probably in the same cost range. At this time of year in frosty countries with failing infrastructure, manholes aren’t typically even close to level with the road surface and may be a significant road hazard.

Jeeps have the handling characteristics of a jeep, and hitting bumps in them is uncomfortable. “Off road capabilities” is not the same as Baja.

Because I drive the same way every day. I know which ones to avoid and which ones are fine. I also have to pay to do maintenance on my car. If I can move the steering wheel a few inches for certain covers rather than spend a weekend replacing suspension, I'll do that.

Huge tyres? Or huge rims.

Skinny tires on huge rims and a lift kit will self destruct pretty quickly. Pavement princess trucks are considerably less capable, ironically.

Huge tires, not rims. I get the big rim idiots babying their purchases. I'm talking about regular SUV tires.

i unconsciously avoid sidewalk grates also. fear of falling forever ig

I would try to avoid driving over them when safely possible, because they make an annoying noise, which I wanted to spare folks living nearby from. ¯\_(ツ)_/¯

As someone who opens them regularly, because so many of the chimneys are collapsing and I regularly wonder how some haven't caved in yet.

Tell me, what alignment is your car?

Chaotic neutral.

Why do I feel good when I avoid stepping on the pavement cracks?

After freezing temperatures, construction, and deferred maintenance, manhole covers can be a damaging obstruction

My car is only two years old, and the one time it needed work …. I hit one of the smaller pieces of road infrastructure - a gas valve maybe. But the pavement was broken up around it so it was a deep hole with a sharp metal edge. It destroyed my tire, a damn expensive tire

Edit to add: for my older car I just had to spend $1,500 replacing a control arm and ball joint. While there’s no way to identify a specific cause, trying to avoid obstructions is a possibility I can control

Around here the chimneys are fine and the road around them has sunk so they stick up a couple inches above the road surface.

It's fun to do on a motorcycle.

I've witnessed a failure like this once but it took a sunken brick crosswalk where we get frost heave into a U-shape with a flat manhole cover in the middle of one lane to get driven over for a couple years until one day the lip under the cover was so busted up it flipped the lid right out when my mom drove over it lol.

The manhole covers are lava!

That's kind of amusing to me IDK why

I was in Oklahoma one time and I opened a lid on a road and the whole lid fell in because the frame broke as I opened it. City was just kinda like "yeah that happens" and I'm like wtf do you mean that happens?!?! Their system was very very fucked though lol

I drive through a new area near our home everyday (in UK).
Some of the manhole covers make a loud "clonk" noise when I drive over them.
I avoid them because it will otherwise annoy our new neighbours.
I used to live off a main road into town.
There was a loose manhole cover there which drove me crazy until I managed to get the council to fix it. Probably just had stones in it making it loose.

When I went to Mexico, none of them had the covers, just holes everywhere on the roads and sidewalks.

They're hella loud when you hit them.

Maybe you and they are on opposite sides of the world so, when the chimneys sink on their side, the counterparts on your side are pushed out.

Around me, they're either 2 inches below the road surface, so a giant pothole, or 2 inches above the road surface, so a giant speed bump.

Red alert! Red alert! Danger!

Big tires don't really help for that though, and lifts like that often have a tighter suspension and a rougher ride. The vehicle you want to drive fast over bumps would be some kind of luxury car that puts a lot of emphasis on having a smooth ride.

When I was a kid, I biked on a manhole cover. Right after I passed it, the manhole cover collapsed into the street.

That Final Destination fear never left me.

This is because people drove a street like tonnele from the 139 to the 495 (07306 to 07047) and witnessed the height issues around the manholes there.

It's PTSDriving. After surviving the doubly bifurcated and traffic-signaled tonnele traffic circle of pain, that stretch of i9 is just the next circle of hell.

No. Slowing may make the bump feel worse to you )unless you do it right) while still being less strain on your suspension

I do this. Its like stepping on a crack or whatnot. I just can't handle one of my tires being on a different surface than the others. For me its definately a my brain is wierd thing.

No, you want your suspension to compress. That's it's job. But you want it to start compressing as it's hitting the bump so it drops down on the other side instead of the whole car dipping.

And I'm not talking about going over it at 50mph. A lot of speed bumps will have a suggested speed posted near or are designed for the posted speed limit. And I'm talking about the people who are basically idling over the bump.

The smoothest transition with least chance of damaging suspension is ….

Mostly stop long enough for the car to stop leaning forward. Then gently accelerate of the bump. No dip, no damage

Meanwhile I’ve paid to enough suspension repairs to not want to hurry up another.
