New tires - that's what I've been missing.
I bought my 2001 Boxster S in June 2009 and had to put new tires on it to pass safety when I brought it back home from Ontario. I put the Hankook v12's on all 4 corners on it back then at around 70K km...
I've gone through 2-3 sets of rears, to the one set of fronts on them since then. I recently had to replace the tires as the inner shoulder on my right rear was getting pretty worn... Like I think I would be on cords soon. I currently have just under 138K km on the car. All 4 tires had variious bits of scalloping on the inside shoulders.
Man - took the car for a spin yesterday after cleaning the wheels and putting them on the car...
Wow. transformed. comfortable ride, quiet. All the grip that I need. Smile to my face.
I ended up getting Kumho ps31 tires. $650 delivered plus $132 for installation at a tire shop less than 5 minutes from work. Had to take wife's q7 in to get the 4 tires and rims to fit.

my tires are from 2001 I think ... my car didn't explode and cause massive havoc like many people think because of the age, but reading this makes me think its time to treat myself.

I'm seriously thinking about putting a note in my phone calendar for mid/early 2019 to get my L and R's swapped.... I think if I can mitigate some of the inside cupping, I should get a more comfortable ride in terms of NVH.

Been about a month with the tires on, and haven't noticed anything untoward with them... Happy.
I've had them chirp once doing a left hand turn from a 2 lane hiway onto a county side road... I'll blame it on going in too hot, and there were recent lines painted on the road....

I used to think that the ageing thing was not such a big deal.
Wrong.
Was driving the SL in Arizona a couple of years ago. The car, a 2003, only had 30,000km on it and they had been easy, Tires had lots of tread.
At 120km/h the right rear failed completely and shredded instantly.
Luckily no damage and no skids.
After that I would not allow tires to age out.

On November 30, 2013, at about 3:30 p.m. PST, Walker and Roger Rodas, 38, left an event for Walker's charity Reach Out Worldwide for victims of Typhoon Haiyan (Yolanda),[53] with Rodas driving[54] his Porsche Carrera GT. In a 45 miles per hour (72 km/h) speed zone on Hercules Street near Kelly Johnson Parkway in Valencia, Santa Clarita, California, the car crashed into a concrete lamp post and two trees and caught fire.[53][55][56][57][58][56][59] Rodas died of multiple trauma while Walker died from the combined effects of trauma and burns. Both of their bodies were burned beyond recognition.[54]
The curve where Walker and Rodas were killed is a popular spot for drifting cars.[60] No alcohol or other drugs were found in either man's system,[61] and neither mechanical failure nor road conditions appeared to play a role.[62] Police found no evidence of drag racing.[63] The investigation concluded that the car's speed – between 80 mph (130 km/h) and 93 mph (150 km/h) – and age of the tires were the primary reasons for the crash.[64]
Tires are cheap. Porsches are expensive. Get new tires.

IMO the issue with old tires is the lack of sticking. No data supports old tires will blow out sooner than new. The difference in grip is huge as the rubber degrades.
Going to the UCR concours exiting off dvp an SL was trying to keep up with me and did some fishtailing around the corner. It was an older gent and I am sure that both woke him up and was caused by old tires.

I have a 10 year old set of sneakers. feet hurt after a 10 minute walk.
They look great lots of tread.
Put on my new set from sport chek, I can walk for miles.
Always like new tires. That extra 5/32 mm of compliant rubber, takes out all the creaks and thumps. It's like brand new suspension and a quiet car.
Put new Continental DSW's on my wifes X5. Drove like used to.
You forget over time, you remember after the spend.

next Spring it will be time to give Zook a call just a matter of figuring out which Country he is in .

Don't people love revived old threads?
It's now 4 years later, and the boxster has about 156K km on it (that's what I told Service Ontario yesterday when I went to 'renew' my stickerless plates).
Even tire wear, still happy with the ride... The rears are at just over 5/32" tread, the fronts at 6/32".... Depending on gas prices, I may get enough km on the car that I will replace the rears with something this season.... alas, looks like the PS31 from Kumho was discontinued in the 2020 season. There is some scalloping wear from some track abuse when I used these tires for a few track days/evenings at grand bend before I got a dedicated set of tires and wheels....
Not bad for a tire with a 400 treadwear rating...
