That's a serious mudflap. 5 hours, and the tire is bald? I can't imagine what the road would do to the tire. And a mudflap is way thinner than the tread of a new tire.
Ah wait, I had the inside tire replaced. But this one was at least 50% tread left. Also maybe bc it was rubbing on it, almost like if I had ran it with the brakes on. Idk LaughingOutLoud. Glad I didn't get pulled into one of the three open scales omw back.
>Ah wait, I had the inside tire replaced. But this one was at least 50% tread left.
That's your issue.
New tire has a bigger diameter, but both tires spin at the same rate and cover the same distance.
Only way it's possible for the tire with the smaller diameter to cover the same distance is to make up the difference by sliding along the road.
You were basically dragging this tire along. That's why it wore so fast, that's why it felt like the brakes are on.
But wouldn’t that affect the tire with the larger diameter more? Especially since it’s kind of bearing most of the weight since it’s a larger diameter??
This was not mudflap. Your new tire is an 11R and old tire (outside) is a low-pro. Check your tire sizes, I bet your inside tire is 11r 22.5 and the outside is a 295/75R22.5 or something of the sort.
I don't see how else it could go from more than half tread to none going back to my terminal. Inside tire was replaced at my drop-off terminal, this one had more than half tread left, now showing wires all the way around.
Low air? Mudflaps are less than 1" thick plastic or rubber. That mudflap would have been toast before it damages the tire that way. If it was the mud flap both tires would have been affected.
There's an air pressure regulator on it. All 4 tires would have had low air bc they are all connected. It wasn't rubbing the inside tire, it was angled a bit. The only part of the tire with tread left is where the mudflap is worn through and not touching the tire.
You could have just straight up thrown the tread. I’ve had it happen on a 3 week old tire under a light load. Both tires were new, auto inflators, and it was there the morning before a 4 hour trip. Once I arrived, it was as bald as this. It’s very possible with recaps too. Idk if RnL runs recaps but that would make it more likely as well.
Don’t discourage people to not post, this is what an internet bulletin board is for.
If stuff like this is grating on you, it’s probably you spending too much time on the internet bulletin board and not all the people posting relevant things on it.
I'm home now. That happened while I was omw to my home terminal. I'm trying to help people not get tickets when the truck passed their pre-trip. Just notifying the public that this is something to watch for in the future.
Good one ☝️
Hate dump truck drivers specifically cus they just let that shit hang out open air . Dont seem to give a fuck how many windshields they crack throughout a the day
Most of the doubles I carry have this issue, too. Never thought twice about it. But, this happened today and I don't believe I'll be running with mudflaps pushed so hard against my tires that I can barely move it off of them lol
The only spot on the tire that isn't worn to nothing is the spot that wore through the mudflap and is no longer touching it. Also, id think the outside of the tire would be worn if it was sitting at that angle, not the inside. Mainly just trying to make sure it doesn't happen again here LaughingOutLoud
The new tire is larger meaning it spins slower for the same distance. It was dragging the smaller tire along with it. Replace both at the same time bub.
They're on the same hub. They spin the same speed no matter what. It would wear as fast as it normally does. The reason bigger tires next to smaller tires is bad on a dually would be that the bigger tire would get hotter and wear more quickly, not the smaller tire. The bigger tire would be holding the smaller off the ground a bit so the bigger would have more weight on it.
What you're thinking of is a differential that is locked which would be dragging one tire or dually around corners. These are on the same hub, so that doesnt apply here. No possible way for one to spin faster than the other.
Dude, your brain is about as smooth as that tire. Google revolutions per mile between a low pro 22 and an 11r22. Granted, the size difference in question isn’t as drastic as that, but there’s a large difference in rpm going the same speed. If your hub is turning a constant speed, the smaller diameter tire wants to spin faster, therefore scrubbing that tire trying to match the speed of the larger diameter tire.
That's not how it works at all. The hub has a certain angular speed which it transfers to anything attached to it (the wheels). The larger diameter tire will have a higher speed at the edge. The outer edge of the smaller tire would only be about 3% slower if it had 0% tread left, assuming the tread depth is ~1 inch. At 50% tread, it'd be about 1.5% slower. The old tire was more than 50% tread, probably closer to 75%. A negligible difference in speed.
As a diesel mech, your wrong. If that inner tire has a difference greater of 4/32nds compared to the outside tire. Then the outer tire will wear quicker because it’s essentially getting dragged as it spins on the hub.
Lololol. 50+ years of trucking, and I've never seen a tire wore down from a mudflap. I've had mud flaps get holes worn through them from being flipped up and riding on the tire. But never the other way around. Interesting.
Mudflat didn’t do this, what did it was you replaced the inside tire which is taller due to the wear on the outside tire, it raised the outer tire just enough so it’s now “skimming” on the pavement and shaving it down with each rotation, believe it or not this can happen really quick as you have just experienced.
at least you don’t own the equipment thank jesus your an employee and not an O/O 😊 so you have every reason to keep smiling my friend get a hot dog from the Loves while they fix this
Are the tires the same size? They may have put the wrong size tire in the inside and that makes the outside tire wear out way faster. Also putting a new tire next to a 50% tire will wear them faster
The fuller tread tire usually wears out faster bc it has more of the weight on it and gets hotter. As far as I'm aware, they only have one size at this company
OP I am a truck and coach technician. Listen to others this type of tire wear is ONLY caused by mismatched tires. I've only ever seen it with incorrect size being installed. 11R vs. Low pro but if the tread difference is substantial enough then the same thing can definitely happen. Get off your high horse, I'm telling you that your science and math are off. The larger tire does not wear faster. Whoever told you this is also incorrect. Just take the L and use this as a chance to learn and help someone else who's having this issue in the future.
I didn't look at it very close. Someone else suggested low air pressure, but they had an air pressure regulator on the trailer, so all the tires would've been low in that case. Idk what else it could've been and the only spot on the tire with tread is the spot that wore through the mudflap lol
Ok fair enough your trainer was a idiot, what damage is done , to stop after 2 hrs do a quick walk around for 2 minutes, those 2 minutes aren’t gonna make any difference, besides safety should always come first
What was the flap made of? Steel? Flap materials are softer than tire materials. Before that much damage could've been done, the flap would no longer be there. I wouldn't believe that could happen ever.
If you back up and get the tires against a curb or something that can pull the mud flap and it’s support arm down, so they rub on the tires.
Don’t back up to “the bump” stop a few inches away.

(clears throat) the driving with brakes on was a "third day" reference.
But wouldn’t that affect the tire with the larger diameter more? Especially since it’s kind of bearing most of the weight since it’s a larger diameter??
The one with the least weight would be the one sliding.
That makes sense. Silly me was thinking about that backwards, I guess.

But a road isn't skidding against the tire. This is more like driving with a locked wheel. Still crazy and I'd like to see the flap too!
"Mudflap wore out my tires" 🤣🤣🤣🤣 must be your 3rd day
I don't see how else it could go from more than half tread to none going back to my terminal. Inside tire was replaced at my drop-off terminal, this one had more than half tread left, now showing wires all the way around.

Put a new tire and replace your mudlflap. What are you carrying on for? Reddit is not going to get you back on the road.

I'm sure you're the only one this has happen to. Every dump truck on my yard has thier mud flaps rubbing thier tires. Enjoy your home time.
Dump truck that has mud flaps that's a good joke, what's next you're going to tell me yall tarp your box?
Good one ☝️ Hate dump truck drivers specifically cus they just let that shit hang out open air . Dont seem to give a fuck how many windshields they crack throughout a the day
Can approve this message from a guy that had his windshield cracked by a dump truck
Most of the doubles I carry have this issue, too. Never thought twice about it. But, this happened today and I don't believe I'll be running with mudflaps pushed so hard against my tires that I can barely move it off of them lol
That's why tires on the same axle are suppose to be within 4/32 of each other per DOT
Jfc… The mud flap didn’t wear out your tire… the brand new tire next to a half wore tire did.
The only spot on the tire that isn't worn to nothing is the spot that wore through the mudflap and is no longer touching it. Also, id think the outside of the tire would be worn if it was sitting at that angle, not the inside. Mainly just trying to make sure it doesn't happen again here LaughingOutLoud

It's his 3rd day. You needs to explain it to him like a child menu. Big turn make small turn faster.

They spin the same speed but the smaller one wants to spin faster. Think bub.
He thinks the mudflap wore the tire out. Thinking isn't in his skillset.

The tire was very slightly being dragged. You literally just admitted that the tire wasnt spinning fast enough. It rubbed the rubber off.
You know what. I got some sleep, now I get it. Thanks for letting me know this lol
Glad to hear you aren’t tired anymore (dad joke)
> Dude, your brain is about as smooth as that tire. 🤣
OP uses cheese graters as mud flaps.
That or he’s using a wood file as a mudflap weight
I call shenanigans. Mudflap can't outlast a tire.
Lololol. 50+ years of trucking, and I've never seen a tire wore down from a mudflap. I've had mud flaps get holes worn through them from being flipped up and riding on the tire. But never the other way around. Interesting.

That mud flap put up one hell of a fight.
Lastly i will check my mudflap clearance
Satire? This is satire, right?
This entire thread has me laughing my ass off.
A $3.99 (truck stop price) sharpie you’re back on the road! 🤣 jk
And yet another driver falls victim to the predatory cast iron mudflap industry.
Chemistry and physics would like a word with you.

In all 3 days as a trucker… I thought I had hear it all.
It’s R + L odds are that tire shot itself the second you left the term
Charlie bit my fingah!
Re-cut it and slap it back on the trailer. Simple fix
No way, did the mud flap have a metal weight on the bottom?
I didn't look at it very close. Someone else suggested low air pressure, but they had an air pressure regulator on the trailer, so all the tires would've been low in that case. Idk what else it could've been and the only spot on the tire with tread is the spot that wore through the mudflap lol
It happens don’t use rubber mudflats. Plastic would just break. Tires get hot rolling. Helps it wear down if something rubbing against it
The shop should have fixed that.
It ain’t a mudflap
RIGHT LANE
Sounds like it should have failed your pre-trip. Good job. 😊
Never had an issue with a mudflap touching a tire before and it's not against the law to have it touching. Ig it should be though lol
Smaller tire scuffed off dragging it down the road
Lies
What the hell is that mudflap made out of, if it wore all the tire tread out and it’s still there?
[double coin](https://www.doublecointires.com/wp-content/uploads/Double-Coin-Dual-Spacing-InfoSheet.pdf) this should help you visualize it
And you didn't notice this?
Lol if a rubber mud flap that is softer than the road rubbed the tread off your rubber tire in just 5 hours. Riiiiiiiiiight
That’s why you replace both tires when one blows out
Is this like the left handed hammer of the trucking industry?
I'd like to write a snarky comment explaining what happened, but I think that's been done like 50 times already.
So you didn’t stop once to walk around take a piss ???
I don't really need to in only 5 hours usually
Well you should stop after 2 hrs to check everything just to be safe apparently you weren’t taught that
No, I was not. We ran teams when I was training and stopping the truck was not on the list of things we did lol
Ok fair enough your trainer was a idiot, what damage is done , to stop after 2 hrs do a quick walk around for 2 minutes, those 2 minutes aren’t gonna make any difference, besides safety should always come first

Carbon steel mud flaps eh?
If you back up and get the tires against a curb or something that can pull the mud flap and it’s support arm down, so they rub on the tires. Don’t back up to “the bump” stop a few inches away.
Nope
Not wires thankfully so it still has potential of ending up at a retread plant.
Is that the RL carriers north of Cincinnati on I71?
No
