An SUV is a type of vehicle that is larger than a regular car and can handle rough roads. They usually have more space inside for people and luggage.

Term

tire compound

"...you notice that tire compound starts to dry out of structures and"

Tire compound is the mix of materials that make up a tire. As tires age, the materials can become hard and cracked, which can make them unsafe to drive on, even if they look fine.

Term

dry rotting

"...there's some what we call dry rotting and the cracking in the tire we want to replace those before we have a failure..."

Dry rotting is when tires get old and start to crack because of the sun and heat. It makes the rubber weak and can cause flat tires.

Term

tread depth

"...they do check the tread depth which is like this is the obvious answer but they do say you know this this tire is discolored or they'll say there's some cracking in there..."

Tread depth is how deep the grooves in a tire are. Deeper grooves help tires grip the road better, especially when it's wet. If the grooves are too shallow, the tires might not work well.

Term

date code

"...there's a date code when that tire was manufactured it'll be a the week in the year and then the last two years it was made so you'll know it's the 40th week of 2012 or whatever it is..."

The date code tells you when a tire was made. It shows the week and year, so you can know how old the tire is. This is important because older tires might not be safe to use anymore.

Term

OEM parts

"...is there a big difference between OEM parts and non OEM parts what do you recommend that tell our listeners what those what's that mean OEM the original equipment manufacturer..."

OEM parts are the same parts that were used when the car was first built. They come from the car's manufacturer and are usually considered to be of high quality.
