Hi guys, I went to a mechanic store and the guy kept telling me I need a new tire (SUV). So I'm wondering that what's the "standard" of the tire, like when do I have to change it? Also, do I have to change my oil every 6 months or so even I didn't use my car much?

Tires

Tire wear depends on several factors, including your driving style and tire maintenance habits.

You need new tires if:

You can see three or more tread wear indicators around the tire
Cord or fabric is showing through the rubber
The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric
The tire has a bulge or split
The tire has a puncture, cut, or other damage that can’t be repaired


Keeping your engine running at peak performance wouldn’t be possible without a fresh oil change. It’s your engine’s lifeblood, and if you don’t change it on a regular basis, it can fast become an ugly, engine damaging mess. As motor oil ages, it wears out and becomes infected with contaminants. Leave that dirty motor oil in your system, and it will begin to thicken, losing its luster and ability to protect your engine. The result? Engine wear and damage, reduced performance and even expensive repairs. Nobody wants that. That’s why we’re here: to help you keep your ride properly maintained and your engine protected with the right engine oil, expert service and advice.
