you want your tires to have the normal air pressure. underinflate tire means wear easily and doesnt have much grip. overflate tire means more grip but less wear.
Worn suspension/steering parts Incorrect tire pressure Alignment
Several items will help with tire wear: *Insure that they are properly inflated according to manufacturer's instructions *Make sure the wheels are aligned *Rotate the tires on a regular basis *Drive with smooth acceleration and stopping. Take turns at a reasonable and safe speed. Squealing and skidding the tires will have an affect on tire wear.
There is no date. Expiration depends on wear. However, you may find the production date on a tire. Look for the DOT numbers on what would be the inside of the tire. Example, DOT 02112 would be the 21st week of 2012 that tire was produced.
Depends on how much it was worn on the edges. If you are in doubt, put these on the back and get new ones for front. - After struts are replaced don't forget to have an alignment. Very important for your tire wear.
Those are small rubber bars in between treads that indicate recommended maximum wear
When tires are made, the tread pattern has grooves in them. There are parts of the grooves that are not as deep as others. When the tire has worn down to that level, the tread has worn away to the point where they are no longer safe to drive on. The bars are clearly visible going across the tire.
its possible that a missing sway bar or link could cause excessive tire wear by allowing more weight to transfer to the outside wheels when turning. more weight means more stress and heat buildup, the ultimate cause of tire wear.
Lights, Gauges, sounds like bells etc., fluid level markers, tire wear bars.
on my 2008 srx i got 40,000 on factory tire & on 50,000 on goodyear replacement, do not let them get pass the wear bars the backend will swap
Always check for visable damage to the tire itself. If there is no visible damage, the easiest way to check tire wear is the penny test. Place a penny "head down" into the groove of a tire, If you can see the top of it's head, your tires need replace, legally. However, you should replace your tire when the tread is reduced below 4/32 of a inch. The easiest way to measure this is actually to us the "Quarter test". Do this test the same as the penny test on with a quarter, for a more accurate reading or check your tires "wear bars" which are bars within your tread that are below the tread and are the minimum safe depth for your tire.
The minimum tread depth in New York is 2/32". U.S.- and European-manufactured tires have wear bars or tread wear indicators molded into the tread. There are portions of the tire that are raised 2/32". When the tread wears down so the tires are no longer legal, these portions will form a smooth bar across the tire in several places.
yes
Camber and toe can both cause inner tire wear.
Yes, if camber is not right the tire will wear prematurely.
Extreme braking and low inflation cause wear on a bike tire.
Yes. Low pressure will cause edge wear. Over inflation will cause center wear.
