- Types of Tire Wear
Tire Alignment
Camber- is the inward or outward tilt of the front tires as viewed from the front.
Toe- is the side-to-side difference in distance between the front and rear of the front tires.
Caster- slope of the steering axis
Proper Tire Inflation
Refer to your vehicle owner’s manual or the tire specification decal on the driver-side doorframe.
For older model cars (prior to 2003), tire inflation information may be located inside the glove box door, fuel filler flap, or trunk lid.
Do not use the pressure molded into the tire sidewall. This indicates the pressure needed to meet the tire’s full rated load carrying capacity, not the pressure specified for your particular vehicle.
Under and Over Inflation
Underinflated tires also have higher rolling resistance, which reduces fuel economy. And, they wear more rapidly at the outer edges of the tread, which means replacement will be necessary sooner than with properly inflated tires.
Overinflated tires are less of an issue. Modern tires can easily withstand pressures that exceed those recommended for normal driving. However, consistently overinflated tires provide a less compliant ride and suffer more rapid wear in the center of the tread, which again means replacement will be necessary sooner than with properly inflated tires.

This popped up while i'm teaching myself how to diagnose some auto issues and just wanted to say, this is incredibly helpful to me personally. -Thank you good sir. Well done.
Thanks for taking the time to comment and glad to hear it was helpful for you!
This is great Sir, clear and concise...thanks!
You are welcome! Determining your tier wear pattern is the first step toward correction.
Watched so many videos but all one need is this video to find out why their tires are wearing out strangely. Good One!
Glad to hear you found it helpful!
I do understand now why my tire has worn that way. This is such a very informative video. Thank you sir
Glad it helped you!
Just came from your very informative cloning video for cannabis, great to know we share another passion as well! Thank you for helping me learn more from this great content,
your new subscriber :)
Great to know you are watching many of the variable playlists that DeBacco University provides!
very clear explanation. thanks 👍🏼
Glad it was helpful for you.
Thanks, mate. good info
Glad to help hope your tires wear evenly going forward.
Very helpful. Thank you very much.
Great to know, thanks for watching and commenting!
Thanks for the video 🙏
You are welcome glad it was helpful.
Outstanding explanation! Thanks
Happy to help and hope you found the answer you were looking for.
very well presented. the graphics along with the narration is impressive. Thanks for your presentation
Glad you enjoyed it!
I am getting a straight line scratching on tyre. Why is that. As if a sharp object is run along the tyre.
Int he tread is harder to explain, but on the side wall indicated some rubbing.
This guy teaches forensic investigators how to solve cases related to tire tread patterns. Boss
That is not all that is taught, but thanks for the comment!
Hello. Thanks for the informative video. I’ve got the camber tire wear according to your diagram. The ride feels normal, but the tire looks out of round. Is it dangerous even thing I still have lots of tread left. How can I tell that it’s just a camber wear not a broken belt? Thanks in advance.
If you see it on both sides this can be an indication tread is one thing, but depending on the age, there is also side wall strength to consider.
Thanks for the video. I have a rear wheel drive car with both rear wheel inside wear more than the out side. The rear wheels have in spec negative camber and toe in (front sides closer than rear). It can’t be due to the toe, can it? Toe in wear should be on the out side. The excessive wear is then from the camber, isn’t it? But the wear is mostly just the innermost strip of the tread, not a gradual slope showing in the video. This confuses me.
Your wear description is related to the camber. Having both rear wheels exhibiting the same wear indicates that there may be an alignment issue or set-up with the driving wheels for the car your describe.
@@DeBaccoUniversity Thank you for the reply. I used an angle finder and checked rear camber. Both have about -1.5 degree which is in spec (0 to -2). It is a 5 link design without camber adjustability. I guess it was designed to be that... There are aftermarket "camber bolts", but they are designed for McPherson struts. I'm not sure if they will work with camber arm... Best.
@@motofan16 what car is your RWD with -ve factory camber specs ?
I have an 18 Altima, recommended pressure is 33 lbs. I keep them around 35 and rotate them every other oil change. I just had them rotated and noticed the ones on the front, both sides, are wearing a lot on the inside and outside edges. Im perplexed on why. I havent paid much attention so I cant be positive they even rotated my tires for sure, it was the stealership that did it. Either way, it doesnt make sense. My pressures in the car all read the same and I have a digital gauge built into my inflater so again, not sure whats going on. Alignment is fine as well. Any ideas?
In general front tires tend to wear more then rear tires. However, the pattern you are noticing suggests under inflation but your readings suggest otherwise. Keep-in mind the recommended pressure comes from the sticker in the drivers door not the tire themselves.
Tires could be too wide for the rims.
What if the wear is all the way across and even on both back end tires? I've already replaced both back struts. Alignment is perfect and tire pressure is asking 35 so thats what we put in. I have gone through almost a grand for back tires.
Is this a rear wheel drive vehicle? Also, when you say "all the way across" is this referring to the entire tread? (Is it parallel with the axle or perpendicular to the axle?)
@@DeBaccoUniversity yes the entire tread. I tried to put a picture but it wouldn't let me and no its a front wheel drive and I have no idea if its perpendicular or parallel
@@karrissawinn7556 Sounds like an alignment issue (even though you say it is perfect). Not sure when new tires were put on, but check for early signs of wear and this will help guide where the potential problem is. Specifically you want to look at the toe or camber angle/alignment of the rear tires.
I’m having the same problem with my Dodge Charger my back tires worn all the way around don’t know why
@@okie-5518 get your trail arm bushings checked thats what ended up being the issue. I feel so relieved having it fixed and my car drives so much smoother and tires are doing great now.
I had fitted 4 x Continental ContactSport 6 on my C Class W205 C250D last year August 27th 2020. Car is re-mapped to stage 1 and currently running at 250BHP.
265/30/19 on the rear side and 235/35/19 on the front side.
This week after doing around 5k miles, I found out that the rear tyres are already worn and need replacing very soon. Never did any burnouts.
The inner side of the rear tyres has maybe 0.5-1mm left. The outside has around 2-3mm left.
On the front side, tyres are still good however, they are also getting a bit weary from the inside than on the outside. But the front side issue is not that serious.
What might be the issue please?
Checking the age of the tires and also the wheel camber would be advised. This DeBacco University video will help you read the side wall information to determine the tires manufacturing date... czcams.com/video/ZtFqmHlhLoQ/video.html
@@DeBaccoUniversity My Chrysler Town&Country van had too much negative camber on my back tires! Fixed it by using hardened lock washers on both top bearing hold bolts.
I noticed My front tires are wearing outside for a little , this problem occurs after alignment.any help plz
Is this even for both tires? If alignment is correct, there is the driving style to be taken into consideration.
Front wheel drive vehicles do not have caster!
Most of the time you can not adjust caster on front wheel drive cars, but it does not mean they do not have caster... low-offset.com/workshop/what-is-caster-angle/
Why are you calling people " suspect" ?
Trust no one;-) (*This is for a forensic science class;-)
and what does this have to do with cannabis?
