What would cause tires (Front and Back) to wear on the outer edges of the tread?

Question

Approx 16000 miles on tires

Answer 1

under inflated Put some air in them

Answer 2

If the dealer adjusted the toe correctly then your problem is simply low tire air pressure. The mechanic should have checked the pressure before any aalignment was made. Caster and camber are adjustments that are usually altered by an accident or something severe damages the front end. When you take your vehicle in for an "alignment" for $39.95 or so you get a toe adjustment, that is all. When the weather changes by 30 degres or so your tire pressures will be affected, up or down, like winter to summer. Check your tires at least every two weeks, check them at the coolest part of the day, usually in the a.m. after the car has been sitting and tires are also cool or at ambient temp. Most tire dealers will check your tire pressure for free, just stop in when they are not real busy.

Answer 3

If a tire is under inflated. then the outside edges of the tire will wear more than the middle. With over inflation the center of the tread will wear first.

Get a good tire gauge, and make sure that you keep your tires properly inflated!

If you have noticeable wear, you most likely are at least 10 and maybe more PSI low on your tires. This is not only causing the tires to wear, it will hurt your fuel mileage!

Answer 4

Either your alignment is off or your tires do not have the proper amount of air in them. Look on the side of your tires and you will see PSI 35 or whatever number. This number is the max air pressure you need in your tire. Also look either on the driver or passenger door and look to see if there is a panel mounted to your car that tells you the recommended air pressure for the front and back tires.

Go buy an air pressure gage ($2 at a car store) and put it in your cup holder area or side of your driver door. But don't forget to check the air in your spare tire!!! These go flat really quickly because of the heat!! It would be really bad to have a flat and your spare is flat too! If you check these once a week, say Sunday's, you will save your tires in the long run.

One other thing to make sure you are doing is rotate your tires with every oil change or whatever is recommended for your car.

Hope this helps!

Answer 5

Two things-#1 being under-inflated tires
#2-toe settings
On all vehicles, there's a placard SOMEWHERE that states the engineer's recommendations for tire size and pressure. Remember-even though a tire says , for example, 44 psi on it, that's the inflation recommended by the tire maker for the tires maximum load carrying. If that tire will fit on a diesel pickup, and a full size luxo-cruiser, the weight on the tire will be dramatically different. For ride quality and best wear, stick with the pressure recommended by the vehicle maker-those stickers are USUALLY on the driver's door or door jam, but I've also found them on the other door jams, inside the trunk lid, even inside the fuel filler door. The US govt required that sticker on every car. Find it, and follow it for optimum mileage , ride quality and tire wear.

Answer 6

Sounds like under-inflation of all the tires. See the info at the below link.

Answer 7

It is most likely underinflated tires, but also could be do to alignment specs being out.

Keep in mind, rotate tires every 5000 miles, Alignment every 15,000 miles or yearly, check tire pressures weekly.

Answer 8

with all four tires wearing, I would say there are only two problems that would cause this, the first being low on air pressure, and the second being hard cornering.

Answer 9

tires could be out of balance, do you rotate tires regularly?
front tires wearing and the front end pulling to one side could be need for a front end alignment.

Answer 10

Everybody is wrong. You jacked up the suspension with stronger springs, didn't you?
