2001 996 Spare

Good Day Group. So quick question can you just replace the actual tire andd not the rim... for the spare. Its a 105/95/17

Yeah, pretty sure you can get a new tire for that rim.

You know, that's a great question because I'm sure mine is original (24 year old rubber) and probably should be replaced if I ever need it. My nephew works at Discount Tire so I have a good connection for a replacement I'm sure. I guess I better put that on the To Do list......

Somewhere on RL is a thread on the topic with tire options that's about 2-3 years old.

I have a �99 and I used my collapsible spare when I got a flat last summer. It worked fine (I only drove a couple miles on it) - I drove home, ordered a new tire from tire rack. 3 or 4 days later my tire came in, I brought the wheel with old tire (which was totally trashed) to the place I had the new tire shipped to, and bam! New tire mounted on wheel. Brought wheel/new tire home, mounted it up and I was back in business. I removed the valve from the spare it collapsed back on the wheel and I put it back in the frunk. I hope I don�t need it again soon�

I have heard the opposite that the tire is not replaceable and has been made obsolete by Continental The entire rim & tyre is still available as a spare part though

Still available from Continental Continental T105/95R17 TL CONTACT CST17 (90M) | Discount Tire & Service Centers (discounttirecenters.com)

My old spare held up yesterday, but I�ll be getting it replaced now.

FYI the 996 non collapsable wheel is no longer available from the dealership

So I went to a tire shop today, and asked the owner to replace my spare. He said it doesn�t need to be replaced. I told him it could be 25 years old. He said they don�t go bad. I asked him 4 times, and each time he said, these spares don�t get used hardly ever, and they aren�t really made from the same type of rubber as regular tires. He said it�s fine.

I also don�t think the spare needs replacing. You really shouldn�t be driving fast with it due to its small size, so you�ll still be fine to putt around town with the aged rubber.

Its easy enough, just pull it out in the sun and look at it, when they start aging they get cracking/checks in the rubber. I've had other cars, that the inflatable space saver fail on inflation which makes it a bad jackstand.. LOL Good Luck!

Jeebus! Not to change the subject but any idea what caused such a catastrophic tire failure!!??

Quotes source post: 19483805

I don�t. I�ll have to ask the tire guy when he sees it. I remember passing over a new section of road and immediately felt a vibration. I was thinking: this new road section is totally messed up!

From my experience that (pic) failure most likely was from tire running low on air. And the bad road finished it off. Maybe at some point in tires life, run low on air and at higher speeds. That will expedite the underinflated tire failure. Once a tire is run low on air long enough, one can fill the tire full but the damage is already done and down the road it will fail eventually. Maybe at the worst time possible. Were little rubber ***** inside tire when it was removed ? those ***** are telltale signs of a tire with a leak (maybe slow leak) having been run low on air repeatedly with sidewalls disintegrating from the inside out..... Thats why the DOT recommendations to never plug tires without first taking tire off rim to check for the 'little rubber *****' showing tire was run low causing sidewall damage and a dangerous blowout possibility. jmo

I tend to agree that it was operated with no air. I think there was a puncture, hence the initial vibration, it lost air quickly enough, and by the time I slowed from 85 to 40, I was probably running the wheel into the rim. That was the 2nd vibration. No ***** inside the tire. These tires were done anyway - 7.5 years old and 25,000 miles, including 4 track days (years 1-3).

Exactly the scenario allcool described went through my head too. They having been tracked increases the probability they were underinflated* right there and then, when they were cold at the beginning of a session and were brought up to temperature on the first easy/sighting lap and the damage to the plies could have been done. *underinflated is any fill pressure below what the operation manual states for the speeds, loads and camber the tyres will see.

Well to be clear, I was tracking with these tires back in 2017 and 2018 when they were new. This flat happened here in 2024 on the expressway. You bring up a good point about tire pressure on the track though. I remember starting with stock pressures and then I had to let out a bunch of air in between runs due to all that heat. In my case, they were overinflated at that time. It was interesting to me that after letting out 7-10psi over the course of the day, the tires never deflated even after sitting for dozens of minutes at a time. I guess all that heat never left the system.

Ya, track tire pressure is a conundrum to tire health. Many times on a tight slower speed track or autocross, very low tire pressure is best for the lowest lap times. But that low pressure heats up tire sidewall excessively. If the track also has high speed sections this compounds the underinflated heat/tire sidewall destruction. But might win you the race,,, unless tire pops.
