What causes wear on rear tires just on outside?

Uneven tire wear is usually caused by improper alignment, overinflation, underinflation or a worn out suspension. Regardless of the season, the effects of winter may linger in your tires: Snow, salt, cold or fluctuating temperatures, and the winter potholes that often afflict roadways, can all cause wear and tear.

What type of wear will appear on a tire with excessive toe out?

Too much toe causes severe tire scuffing and may create a sawtooth or feather-edge wear pattern across the tire. Note that unlike front toe, rear toe causes a telltale diagonal wiping or scalloping effect.

What does it mean when your tires wear on the outside?

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.

What causes outside tire feathering?

Improper tire alignment can cause your tires to wear unevenly and prematurely. Feather edge tire wear: Tires are “feathered” when the tread ribs are worn lower/smoother on one side and higher/sharper on the other. This is often caused by a combination of improper alignment settings, such as excessive toe and caster.

Why do my rear Tyres wear on the inside?

Scalloped Tires Cupped or scalloped dips appearing around the surface of the tire tread wear could indicate loose, worn or bent suspension parts. Worn shock absorbers or unbalanced tires can also cause cupping, but the cupping would typically be more indicative of a concentric pattern.

How does rear toe affect handling?

Toe adjustments on the rear tires also have an effect on car handling. Toe-in on the rear creates understeer, which can help with cars that are oversteery on exit. The tradeoff is wear and heat in the rear tires. Toe-out on the rear is generally wrong, as you’re likely to get more oversteer on exit.

Why are my tires wearing in the middle?

Over inflation creates center wear, which is a thin tread in center of tire. Under inflation causes edge wear, which is a thin tread along edges.

Why are my rear wheels slanted?

Quick answer, some cars have the bottom of their wheels slanted outward to improve handling performance – also known as negative camber. Cars with negative camber maximize contact between its tires and the road surface when cornering – further increasing grip for the driver to corner faster.

Why are my rear tires wearing on the inside?

Positive camber angle forces the top of the tire to stick further than its bottom. This causes its outer edge to wear down. Negative camber angle, on the contrary, forces the top of the tire to angle inwards and the bottom of the tire to stick further than its top. This results in inner tire wear.

What causes outside edge wear on the outside of tires?

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.

What does tire tread wear pattern mean on a tire?

Tire Tread Wear Patterns. Outside Edges: Tires that are worn on the outside edges have been underinflated. There is excessive contact with the outer edges of the tire and the road surface as the vehicle travels down the road.

Is it normal for tires to wear outside of a car?

Indeed, tire wear outside of a vehicle happens to be a common occurrence with many causes. Remember that tire wear patterns give you vital clues on your vehicle’s suspension system’s health and functionality. So what would cause a tire to wear on the outside?

What are the signs of Underinflated tires?

Outside Edges: Underinflated tires wear on the shoulders or outside edges. There is excessive contact with the outer edges of the tire, and the road surface as the vehicle travels down the road. Center of tire: Overinflated tires wear in the center. There is excessive contact with the center of the tire and the road surface.
