Tyre wear outside edge

Front Tires Wear on Outside Edge : Causes and Solutions - Tire. Why do front tires wear on the outside edge? What causes wear on the outer edge of tires?


What does it mean when your tyres are on the outside edge? What is the outer edge of my front near side tyre?

If your tyres are worn on the inside and outside edge, they could be under-inflated or leaking. This could cause the edges of your tyres to have more contact with the road than usual. Taking corners too fast. The inside edge, outside edge, or shoulder will show considerably more wear than the rest of the tyre.


Source of issue Camber wear can be caused by: suspension misalignment, a bent strut, a dislocated strut tower, a weak or broken spring, a bent spindle, or collapsed or damaged control arm bushings. Front tires wearing on the outside edge is usually a result of aging coil springs.


As they lose height, so does the vehicle, causing the whole suspension to misalign, especially in camber.

If the leaf springs are also sagging or wearing out, they cause caster misalignment, which may worsen the situation. Outer-Edge Tread Wear Tread wear on the outer edge of a tire is rare these days, but it does happen.


Positive camber, caster and toe can lead to wear on the outer edge. If you see edge wear on one side, check the thrust and setback. But, it should be note the leading cause of outer edge wear on modern vehicles is over-enthusiastic cornering.


Tire Underinflation Underinflated front vehicle tires can cause excessive or abnormal wear on the outside perimeter of the tires. Underinflated tires tend to fold inward towards the middle, a condition that causes the outside edges of the tires to press downward with abnormal force, which can cause excessive outside tire wear. One-sided shoulder tire wear : This type of irregular tread wear means the inside or outside shoulder rib of the tread is significantly more worn than the other ribs.


Also known as camber wear, excessive positive or negative camber often causes this type of wear. Remember that tyre pressures must be increased for heavier loads.


I am getting very uneven tyre wear on my EM which is especially noticeable on the two fronts. Tread is fine across the width of the tyre inner edge (slightly worn) to three quarters across.


Camber is the vertical angle a tyre makes with the road. When viewed from the front of the car, negative camber means the top of the tyre leans inwards, but too much can result in excessive wear on the inside edge of the tread.


Wear on the outer edge of a tire is rare these days, but it does happen.

However, if the bottom of the tire is leaning to the outside, then you have negative camber. The negative camber is a leading cause of your car tire wearing on the inside. On my first FLI fitted General Grabber AT tyres, the two front tyres suffered from outside edge wear. It looks like your running too much camber and thats worn the outside edge of the tire.


No its not lowered. However, Its significantly higher than standard for some reason.


Ours has done 18K and the tyres are down to 2mm on the outside edge, 3mm in the centre and 4mm on the inside edge of both rear tyres It seems that the panda runs mm tow in on the rear wheels as standard. If outside edges of tyres are wearing on both edges equally then its your tyre pressure being too low – you’re getting a bowing of the central band of the tyre with less pressure being exerted.


If the wear is on the outer edge of the tire, it is often brought about by positive camber, toe, and caster. You may be surprised to know that this is the leading cause of outer-edge tire wear. One can see the wear from hard cornering on the side edge of the wall but it's the bits breaking away from the small winter tread bits on the outside edge of the road face of the tyre that concerns me the most.


Tyre pressures have been correct. The only thing I can think of that might exacerbate outside edge wear in the rear MIGHT be tired shocks.


If the body is leaning excessively in corners, it might cause the weight to load a bit more onto the outer edge of the outside rear tire. As the tires’ sidewalls flex, a solid axle does in fact lean relative to the road. This can cause premature wear to the tyre structure, reducing its strength.


Clean off spilled oil or solvents If you spill petrol on your tyres, or drive through some really dirty water, make sure you clean whatever’s left on the tyres off with water and washing up liquid. The outside edge of my front nearside tyre is completely worn with the remainder showing an even depth of approx to 3. The offside tyre is wearing on its inner edge. These are Continentals and have covered 30miles.


I pointed this out to my dealer who tells me that this wear is normal with all E and C Class platforms. Bald tyres around edge but main 75% good- MOT failure?


I have my MOT coming up soon so have been looking at what can fail the MOT and trying to put it right before the test.
