|
|
I bought a continental CT22 165/80/15 for my spare wheel, its really nice. Im thinking i will buy 4 more and keep them in storage since theyre kinda hard to find. Is this ok to do even if i use them in say 2 years? If i keep them indoors protected they should not age or damage right? _________________ 03/1971, 1302 Super Beetle 1600 dual port

Keeping tyre for 2years is fine.
Most tyre manufacturers recommend replacing tyres after they are about 6years old, as longer than that and the rubber starts to degrade, especially if the vehicle is out in the weather all the time. _________________ Rob

I bought a '71 Honda 750 motorcycle in '86, and it had the original tires with less than 5000 miles on them. The tread was perfect, and they still had the little rubber nubbins on them. They were almost bald in 200 miles. Two years out of the sunlight/weather sounds fine.. 15, not so fine.
My jeep tires are 30 years old now, and they are CRUNCHY. _________________ '70 Beetle, 80k miles in the early 80's, gone.

Tires can be stored 5-7 years under ideal conditions: kept in the dark (no sunlight) and away from ozone sources (away from electric motors or ionizing air cleaners).
Keeping the tires frozen adds another 2-3 years.
Any visible sidewall cracking means the tire is ruined and should be discarded. |

My old mans Rewaco trike still has its factory 1997 Khumo tyres.
Its lived in the garage under a cover all its life and only comes out for an occasional blat every few weeks when the weather is fine.
The tyres still look almost new.
Be a totally different story if it saw sunlight on a regular basis. _________________ Quick little bug, you got a Porsche motor in that?

Hmm sounds good then! Thanks everyone.
Does anyone have any experience of the ct22 continental? I had never heard of them before despite being available in 165/80. _________________ 03/1971, 1302 Super Beetle 1600 dual port

Oxygen eats them eventually, hardens them, and you get the cracks.
Park on a speedbump and then look at the sidewalls.... If there is absolutely no cracking, then they are probably okay. But they won't live forever, even unused. |

They're on a 390kg trike, there;s no weight on them and there is 17 years of tyre shine on them they are probably impervious to oxygen _________________ Quick little bug, you got a Porsche motor in that?

Err right Joel, so you filled them with nitrogen so there's no oxygen inside either? :-) _________________ Rob

I don't know if filling them with nitrogen helps, but stacking them horizontally will eliminate the risk of flat spots during long term storage. _________________ Safe Sex: The Next Best Thing To Being There.

This is the reason that RV people are so militant about changing cracked tires.
You very rarely get a slow controllable leak.
Typically you get a BOOM and then you are rolling on the metal rim (down the highway at 60 mph).
Its excitement for sure, but the kind I'm not manly enough to enjoy :) |

There was a degree of sarcasm in my response but in saying that tyres seem to age from the outside in and rarely seem to perish on the inside not being exposed to the elements.
I've seen a lot like that on the barnfind bugs I've dragged home and even the spare tyre of my fathers 1992 Mazda before he sold it was original (we owned it since new) and had only been used a few times but after 20 years had perished cracks in the wall yet when it was pulled off the rim was still like new on the inside. _________________ Quick little bug, you got a Porsche motor in that?

I remember a thread on here a few years ago about this subject. Lots of opinions about when tires should be replaced due to calendar age. There were also other posters who were comfortable running tires showing no visible cracking or other obvious issues until they needed to be replaced due to low tread.
A lot of us (to include myself) don't use these old VW's as daily drivers thus these cars see maybe 2-3k a year of hobby driving. My 69 Vert has 10 year old radials w/1" white walls on it w/maybe 6k on them. The car is always garaged. I know there has to be many of us who are not going to change tires because of calendar age. My 67 has radials that are probably 15 years old. They are not cracking either and appear to be in good shape. I know they can be degrading internally but I just can't see throwing aways tires away because they have reached a certain age.
I've been on this site for 10 years and I can't recall anyone posting about tires failing due to being past a certain age?
It would be interesting to see people post about how old there tires are. _________________ Contact me at [email protected]

I for one won't be changing tires just because they have reached a certain age. If the rubber is not age cracking and doesn't seem to have gone hard, then keep driving them. Some brands do seem to last longer though. Most Michelins I have seen do show signs of slight age cracking, but this takes at least 10 years of daily driving to show it. My bus has Michelins that are now 14 years old and show zero signs of deterioration. This is not a year round daily driver however. My '66 beetle runs the Coker BF Goodrich whitewalls that are now around 15 years old as well. Hobby car use only, they still look new. My recently acquired '62 beetle came with bias ply tires that are Volkswagen "Golden Miler" brand sold by VW Canada and very likely date from the '70's. These tires have 75% tread remaining and look fine on the outside, BUT the inner sidewalls are cracking. They will be replaced for this reason, but this is mentioned to remind others to inspect the inner sidewalls too. The outers likely had some protectant applied over the years, thus the cracks did not form... _________________ 1974 "Restfalia" Camper 2000 cc EFI 2001-

Well it seems two things, the elements and oxygen, cause them the degrade. Sorting them inside away from sun, rain etc and extreme temperatures will eliminate the first amd for the second, i guess tightly wrapping them in cling film will minimise exposure to oxygen? If the film is static and sticks to the rubber then virtually no air could contact them i guess.
My old 165sr15 snow tyres were at least 20 years old and had gouges and cracks in the side walls. When i first got the car (and had no experience, or, you could say, common sense either) i actually painted them with some black paint to fill in the cracks!! Thinking back now, i did over 80mph with those tyres... _________________ 03/1971, 1302 Super Beetle 1600 dual port
