I took my 2018 in for service last week and the Porsche dealer said my tire treads were fine, but my front tires are from 2017 and have a little cracking in the tread. Said they should be replaced. To me they look fine, but are 6 year old tires fine to drive on or are they trying to make some extra money. ( I am also selling my car within the next 3 months).

Wondering why the experts all recommend replacement at 6 years? It's not an arbitrary number; tires tend to lose a lot of their safety and performance capabilities past the 6 year mark.

Visible cracking on the tread is something I would want to resolve before pushing my car hard at all. I have replaced multiple sets now at the 6 year mark because they won't pass tech for HPDE events (at least in my experience).

Dealer is right. Tires age out regardless of how the tread looks. You'll probably save a bunch if money buying tires from anybody but the dealer.

I would have agreed with that until just this week when I purchased a full set of Michelins from them (in stock) for within a few bucks of Tire Rack prices. Install was a little higher but that was mainly due to the center lock wheels.

Porsche recommends tire replacement every six years. I follow that. Getting an extra year out of my tires but ending up in a ditch doesn't seem like a worthwhile proposition. If you're driving to and from the grocery store, no need, you'll be fine. If driving in a performance fashion on a backroad, get a new set.

You mention you're selling your car, you can probably do without replacing them. Either let the next owner choose which tire they want on the car, or, if trading it in, let the dealer handle that.

Also, my dealer matches tire rack pricing. I always buy them through the dealer. They also have excellent equipment and if you explain how particular you are about your car and condition, they probably are going to make sure someone that has experience does the mount and balance and doesn't mess up your wheels.

My Porsche, BMW and MB dealerships will match TR pricing if asked. None offer that, but if asked they will all match. The Porsche dealership always seems to have stock as well, might need a day to get it to the dealership, but they have stock in whatever warehouse they store their tires.


My experience.

Surprised the OP got that many years out of a set of tires, esp summer tires. I get more out of the winter tires b/c I am consciously /subconsciously trying to go easy on the winter tires.

If the OP is selling, then it comes down to the calculation of what they feel a prospective buyer will want, 1) a new set of tires, 2) or will they not be happy with what the OP put on the car, 3) will they view a set of 'old' tires as poor maintenance etc. If the car I was selling was a 'cheaper' vehicle I would just keep the old tires on (as I have done selling the 2 last vehicles, they were not old tires, but were sold with less than 50% tread). If the car is a 'higher end' vehicle I would personally just spend the $$$$ for a full set, and hope to get my asking price.

I personally would view a 911 with 6 yr old tires in a different light than one with a set of tires 1-4 yrs old. That being said, a 911 with 6 yr old tires likely was driven pretty lightly, and not tracked.

You should replace them. Dealer is correct.

I agree 6 years of age is about the max. However, how long tires stay usable and safe also depends upon where the car spends most of its time. If 90% of it's lifetime is spent inside a climate controlled building with little sun exposure, they can live longer.

However, any visible signs of cracking requires replacement at any age.

In this scenario, as a buyer, I'd prefer to see the original date coded tires on the front with an adjusted selling price.

Bonus points if the seller called this out unsolicited. I'm buying the seller.

93 in a 45, of course it was the tires.

rwbern

Does not compute! 991 forum & talking about six year old tires? Even we senior citizens drive enough to warrant tires more often.
I suggest you change the tires, get on the road & enjoy it! :-)

There are factors to consider along with age.
