Wear on the outside both edges is a sign you are running the tires with too little air pressure. Wear in the center is a sign you are over inflating the tires with too much air pressure. Cupping of the tires is a sign of worn shocks or struts. Wear on the inner or outer edge of the tire is a sign that the front end needs aligning. Also feathering of the tire is a sign of a front end out of alignment.
One of the signs of tire wear is when you see the tread disappearing and falling off. If you check your tires you may notice that one or more has very little tread left. Different signs of tire wear also include seeing the steel belt coming through the rubber, and your ride feeling a bit rougher.
Grinding noises, wandering steering, strange tire wear.
It is important to recognize the signs of part failure in a car. The signs of a bad rack and pinion are unusual tire wear, the steering is off, and fluid leaking from the front end of the car.
When the tire tread wears down to the wear bars, the tires are ready for replacement.
yes
Extreme braking and low inflation cause wear on a bike tire.
Yes, if camber is not right the tire will wear prematurely.
Camber and toe can both cause inner tire wear.
When the wear of a tire's tread is greater on one side than the other, this can indicate an alignment problem IF the tire on the opposite side of the axle does not show this same alignment problem.
Yes. Low pressure will cause edge wear. Over inflation will cause center wear.
no. changing a tire does not change the alignment aspects of a vehicle. alignments are encouraged to be verified upon a new 4 tire install for sure or once a year after snow is gone. of course if your tire showed signs of alignment wear when retired that is a different story and of course should be checked along with the front end parts. this is usually noticed by hard inner or outer edge wear on the retired tire.
A tire alignment is not necessary when changing tire sizes. You can tell by the wear on your previous tires if you need an alignment. If you have uneven wear, get an alignment.
