There is no reason you can't replace 1 if they still have roughly 75% tread left.

Suggestion
If nothing else just replace the 2 rear (or front?) of which 1 is busted, keep the good tire, and then when they reach 75% tread you have a perfectly matched spare to rotate in on occasion.

I'm wondering why he says you need to replace all four.

I busted 1 tire off my summer tires and I need to change the whole set (the guy won't change just 1 given that it's a AWD)...

ok sounds like I definitely need 2 sets - however, the best option seems to be changing only the rear train (both tires) vs.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi,
I am considering buying all season tires for my C4S which is a daily drivers and is not intended to run on the track.
I heard only negatives about these tires (goodyear eagle F1 A/S) - and I was wondering why. It's not like I am driving on the autobahn and cornering every turns at 80mph+
Thanks for your feedback on what I think is a good compromise
Compromise- that's the problem. It's the worst of both worlds. Mediocre handling for your high performance automobile in the summer and poor foul weather traction in the winter. I'm wondering why you want them so much.
well... I busted 1 tire off my summer tires and I need to change the whole set (the guy won't change just 1 given that it's a AWD)... and I need to buy a winter set
hence I am looking at $2500 for both + I have limited space to store them... hence the compromise
Which tire is bad? What condition are the other three? Tread depth? I'm wondering why he says you need to replace all four.
I lived on the South Shore for awhile and I think you'd benefit from having two sets of dedicated wheels/tires for a couple reasons. Better performance winter and summer. Longer life from the more expensive summer rubber since it's only on the car 2/3 of the time. I actually switch from 18" in summer to 17" in winter. Taller narrower tires cut through snow better.
You could probably store your winter set at the dealer or indy. I know that's pretty common. Or you could just try the A/S and see how they work for you.
My tires still have about 75% thread...
I currentl have bridgestones right now (front & rear). The other option would be to get a set of winter tires and just change the rear tires on the summer with Sumimoto - if they're any good

Why put half-assed tires on your high performance Porsche? You may as well just put in 87 octane gas in the car. After all it's a daily driver and not intended to run at the track (It's not like you're driving on the autobahn), so why bother trying to make peak HP?
Why not go for the cheap oil too? After all it sounds like you rarely run it up to redline on the street, so why not save a few more bucks?
Or, here's a thought. Why don't you use summer tires in the summer and winter tires in the winter. They may provide just the edge you need to avoid an accident that could prove to be far more costly than a set of tires.
Here is a possible solution:
If your other tires are worn beyond a 5% difference in radius, the Tire Rack can shave one tire for you. Here is a link:

http://www.tirerack.com/tires/tirete...sp?techid=136&
That Tirerack link is informative. Sounds like you could just replace one tire if the others are truly at 75%. Might be a good time to measure tread depth on that other rear tire.
I had a set of all-seasons on my '89 C-4. Handling was bad in the summer and poor in the winter. They are, to be sure, better than summer tires when the snow falls, but I found that they were still scary in the snow. Go for 1 replacement summer and 4 snows - you will wear out each set half as fast!!
Even if your car wasn't awd, tire shaving is good to consider to match a new tire to a partially worn "sibling." Some tire shops try to sell tire shaving with every set, arguing that they can get your tires really "round" by shaving off the high spots to match the lowest spot on the tire. This has largely been unnecessary. But shaving to match a new tire to one that is already worn is appropriate and less expensive than replacing the pair.
ok sounds like I definitely need 2 sets - however, the best option seems to be changing only the rear train (both tires) vs. the entire set of summer tire
