Question guys. How do you know when your tires are done? Yes I can easily look at it for treat wear loss and I can do the quarter thing between the tread. But I was curious on if their something else that can be done to know if it is dangerous to drive on it? I am in my stock tires and I THINK they are almost done because I put 8,000 miles on them. But they look okay to me.. but others have said that the stock tires are done for at 10k miles. Is this true? I wish their was a device or something else that can help determine if I should swap tires or not lol. I'm still planning on driving with it for another 5,000 miles... bad idea?

 

Unless they're corded, look like a racing slick, or have cracks/splits in the tread I'll keep using them.

 

There should be tread markers in the gaps around the tyres, as soon as they wear flat to the road, that's the manufacturers sign that the tyres have met the end of life, if you are thinking you still have rubber on the tyres so you'll be ok well think again when you get a ticket for your trouble or even worse you hit a puddle of water at speed and lose control, water needs a place to go and tread is where it squirts out of, if you don't have tread the water will literally lift you car when you hit it, your driving a high powered car it deserves good rubber

 

well usually if you have to ask they are done lol, but you can measure the tread depth left and that should give you an idea if you have enough left. Also my stock tires died at about 4 k... they had a ton of wear on the inside of the side walls.

 

Yes, it seems the inside of my sidewalls are wearing out more than any other area. okay. Thanks guys. looks like im just going to have to get a professional to judge it. This is not my daily so im not to concerned at the moment but water is a big factor like jonno99 says.

 

On my car, I replace the tires when they get to 4/32 of tread, or when they cord. Which ever comes first.

 

Damn! I would still run them at that tread... DD though...
