So I looked at my tires - and I could have sworn that they were less than 5 years old - but they're actually 2014 date code. So...old even though they look new, have never had a puncture, and only a scant few thousand miles driven. Apparently the PS4S are being discontinued and NLA so my only choice in the Michelin brand are Pilot Sport 2 or Pilot Sport Cups. I live where it is dry and mileage is not an issue - anybody have experience with either of those...or something else?

Check your records to determine when the tires were actually installed on your vehicle. Even though they're 2014 date codes, they may have been sitting in a temp and humidity-controlled warehouse for a couple of years. If that might be the case, and your car is garaged and infrequently driven, I think you can get a couple of more years out of them.

I'm pretty sure they've been on the car since close to 2014...I made sure I got fresh tires, not ones sitting in a warehouse. Yeah, I could get a couple thousand more miles but I think they might be done and I'm detecting a small vibration which may be due to flat spotting/hardness (per Marco at TLG)

Replacing tires due to age alone is not the only factor.

Factors that my contribute to the length of the usable tire life include temperature (cold/hot cycles), sun exposure, usage (year round vs. seasonal), and other factors.

If you track your car it's best to error on the side of caution.

My driving is pleasure-use only and low mileage per year.

My last set lasted 10+ years with no signs of cracked sidewalls, discoloration, or flat spots.

Ben,

I have PS2s on my car, and I love them. For reference, though, I last had the Sumitomo HTRZ IIIs previously, so an OK tire, to a great tire....Of course, it is going to be nice.

I drive 100% street, and for my skill level, they are quiet, smooth, and comfortable. I don't really drive much in the rain, so I can't comment, and I never push it in the wet anyway.

When I had them installed, I didn't tell my wife what was one to the car, just that it was at the shop, and she noticed that the ride was quieter and smoother on the first ride, so it was noticeable. i don't have experience with the Sport Cup 2s, so I can't comment or compare. FWIW RStrada is a Michelin dealer, so they can order, install, balance and align all at the same time, which is what I had done.

If your tires aren't hard, bald, or dry-rotted, there's no need to change them.

the main thing that degrades tyres that haven't seen heat cycles or just worn is UV.
Tyre manufactures store tyres in so that UV protected and pretty sta le temp and humidity environment.
If they have been locked away in your garage and not cracked or turned to plastic yet keep driving!

Hey guys I'm about to order tires also and need a little input on size. I have a NB 97 C2 that has the 17" cups and I'm switching to 18" hollow spokes. Right now the car is stock height so it's in 4x4 mode until MCS gets here. I see the stock 18" size is 265/35/18 R and 225/40/18 F. Can I run 235/40/18 F without spacers? and are 285/30/18 R the right way to go?

I've tried both these combos and they both work well on a NB lowered to RS+10.

Normal Size:

- 225/40r18, OD: 25.1

- 265/35r18, OD: 25.3

+10mm width:

- 235/40r18, OD: 25.4

- 275/35r18, OD: 25.6

You can also run +20mm:

- 245/35r18

- 285/30r18
But I haven't tried that yet.

Compared to stock, the +10mm sizes have a slightly larger OD so you lose a little torque and gain a little comfort. The +20mm are slightly smaller OD so you gain a little torque and lose a little comfort.

+1 on the PS2’s. I ordered mine (along with BBS RIA rims) from Rstrada (mounted, balanced, with spacers, etc.). I had Continental Extreme Contacts and they came with the car when I purchased it, so I was unsure if I was stepping up or down in feel. I have found the PS2’s to be much smoother, although some of that’s probably in my head because I also love my new rims. I have found nothing about them I dislike.

+2 for the PS2's. I find them much smoother and grippier than the Continentals or Bridgstones before them. I only use N spec tires. Current ones are N3 but there is an N4 upgrade now. Porsche N spec Approval. Understanding it When Choosing Tires (flatsixes.com)

I've had the N4 version PS2's for a while (circa 2016), got them in the 235 and 295 sizing for the turbo wheels, just replaced them with the PS4S same size. no N spec

Hi Ben,
Since it sounds like you don't drive your car much, consider less expensive tires as for you, tires seem to age out before they get too many miles on them.
