Changing tires should be primary about safety. It can be dangerous to have an old tire pop, or suddenly go flat. Especially when you are driving on freeway or busy road. A good rule of thumb is not to drive more than 50,000 miles on a set of tires.

A well-known "life hack" with tire tread is the "Penny Trick" or "Penny Test". You can stick a penny into the tire tread and the general rule of thumb is if you can see all of Lincoln's head, then you should change the tires tested. The one caveat is not all tires are the same. For off-road tires and quarter is better suited than a penny. We recommend getting an opinion from a mechanic or certified technician.

Oil plays three major roles within the engine. First, it lubricates all the moving metal parts so they don't damage one another. Second, the oil flows through the engine and removes heat, effectively helping to keep the engine cool and prevent any overheating issues. Third, oil prevents carbon deposits from building up on and damaging the cooler parts of the engine.

Tire tread is the rubber on the tires circumference that makes contact with the ground. Tire tread depth is usually the determinant of tire life.
