Replacing Tires bc of Time?

What’s the appropriate interval to replace summer performance tires these days? The front tires on the M3 are date coded 2018 and I’m kind of thinking this should be their last season, but is there a rule of thumb?

Some say 6, some say up to 10 years, but there is no set rule. It depends on sun exposure, heat cycles, the rubber itself, how it was used, etc. etc. Use common sense.

My local Porsche dealer was harassing me to replace the front Michelin Super Sports on the factory 18” wheels last summer. They were dated coded week 31 of 2015. I informed them I would be installing 19 inch wheels so they left me alone after that. It was noted on two R.O.s to cover their ass though. 6-7 years seems to be the norm these days.

Cool. I’ll plan to do it next year. By then the PS5s should be out, too, I suppose.

Hopefully! I am waiting on them as well. PS5S launch was originally suppose to happen November 2022. I later heard Q1 2023 and that ship is about to set sail.

Six years is a good general timeframe. It all depends on storage and UV exposure. My LR4 winters are on their 10th season. But the tires are away from the sun >95% of the year and are mounted 4 months of the year. They still look and feel excellent but this will be their last season. They are at 19k miles.

It recently dawned on me that my 2017 X5 with 8200 miles on it is still rocking its factory run craps. I suppose I will be forced to replace them in 2024.

I had several cars a couple of years ago that I had to put tires on - not because the wore out, but because they were 7+ years old.
I also replaced the tires on the car trailer and boat trailer and utility trailer as they were 15 years old or such.

I bought 25 tires that day. LOL
Took me about a month to get them all mounted (all told).

Agree with the consensus that 6-7 is probably about right—at least for a daily driver or cars left out in the elements. I wouldn’t push it too much, unless I had a conditioned garage and multiple vehicles.

Who wants a tire failure while driving?

BTW, same goes for bicycles. And we rarely think about those tires…
