hi geoff
i recently replaced all the tyres on the crown victoria for that very reason.
after 15 years, the original ones i put on during the restoration had only done about 25,000 miles and had heaps of tread and good sidewalls, but one of them had a broken wire come through the edge of the tread.
i suppose we were fairly lucky, the wire caused the tyre to go flat, but it happened overnight.
i threw them all out and got new ones, better to be sure than sorry.
as a matter of interest, i changed the tyres on the van at the same time.
bit exy, 8 tyres in one hit, but hopefully worth it.

Wouldn't you think ,if this is SO important.....that the Gov't or someone in a position of authority would have demanded a clearer system of date identification ( like print the date for FFS  )......this subject was also dealt with fleetingly on one of our current affairs programs a while back..... had a look at the tryes on the back of our Chevy roadster....1981.....still look OK too.....might be nearing time to get some newies....  |

Aust army is currently disposing of $$$$$$millions worth of tyres that are out of date, many of which were never used and straight from storage ,cars,trucks the lot.
It would make you cry so seriously have they taken the problem(or is it worry about potential lawsuits in case of an accident) Probably the latter!!!!!

It's all (bad) news to me  Tyres are a big thing when you look into them...I've never been able to understand all the writing they put on them so I found this site...it helps. Are they saying I have to chuck out a perfectly good looking tyre after FIVE YEARS!!! ....... not likely Cobber. |

Mates.....we have “shock jock” radio personalities ... and we have “shock jock” TV programs  That TV program smells a bit over the top to me. You will have noticed half way through the video the tyre manufacturing rep. says age of a tyre is not the main cause of failure... he probably had a bit to say about under or over inflation of tyres and overloading tyres........but it is obvious his contribution was heavily edited. In Europe and America they have speed limits of 130 kmh and sometimes higher on some of their roads....I'd want extra good tyres on if I was doing those speeds regularly. My daily drives have never had tyres that lasted six years...they wear out long before that. But me putt putting along in my old FJ... towing a 'van that weighs far less than the load rating of the tyres on it will not have the tyres changed just because they are six years old, if the side walls are cracked or the rubber is hard or the tread is low or wire is poking out or it has bulges in it... of course it will be discarded. The tyres I put on the FJ after restoration were there for 17 years .....I replaced them prior to the run to Mount Gambier because the tread was down a bit too much......... maybe they don't make tyres like they use to . If I want to play it real safe.... I'll stay home, it's plurry dangerous out there. Cobber. |

Nothing "Shock Jock" about this one Cobber.
The research, reports and tyre company advisories have all been around for years now.
I've just bought new tyres to replace the quarter worn ones on the van, and will be changing all 5 on the tug next year even though they have more than half their tread left.
In view of the overall cost of running a traveling rig, they represent only a small fraction.
Cheap insurance.

Guys, please take this issue seriously It happened to me on the way home from the 2006 Trevor Roberts Memorial Run ......the 39 Chev had what looked like good tyres with about 90% tread, and no evident tyre wall cracks ...... On the way home from Harvey, the right rear tyre peeled about 30% of its tread, but fortunately didn't explode. The car was towing 900kgs of Masonite / Jarrah framed caravan and traveling at approx 85 kmph .......could have been distrastrous had it exploded Had the tyre exploded, the following year the WA vinvan group may have also had a Mark Taylor Memorial Run ;D  Mark |

Hi All,'
I've driven a miles, on every sort of tyre pretty well that you can use legally on the road. The wires are only on steel radials, not older conventional "rag"tyres
I've had a lot of retreads fail ( mainly when they were all I could afford). & I've driven steel radials so hard the front ones had wire showing both sides with wear. I worked once for a couple of months in a retread factory, so I have an idea how poorly quality control used to be maintained.
But I believe if you keep your tyres inflated in the right pressure range for the load rating, ie follow reccomendations from the manufacturer, you should be unlikely to have a failure.
But you should always keep an eye on your tyres for damage anyway. It only takes a minute to crawl under your car & look at the back of the tyre to make sure nothing is damaged. If you have to, park one wheel up on a gutter, then slide under in the gutter, you should have enough clearance to visually eyball the tyre. Even skinny guys like me can manage.
I believe a lot of the problems blamed on tyre age arise from neglect. I'm not replacing any of mine until they show irregular or excessive wear, or any form of damage. This problem didnt come down with the last downpour.
Call it as you will, I'm sticking with experience not "expertise"

Working in a tyre shop I see lots of failures in tyres and of late have noticed more steel belted radials delaminating and separating in the tread. Most caused by age and some by damage from gutters/potholes or road hazards. JBJ is right in saying that you should look under your car everynow and then and especially look for eggs in the side walls.
Last week we put a very rare Cadilac on the hoist to have some white walls fitted. I immediately got the owner to look at the inside of the front left tyre. A huge egg in the side and the tread was starting to lift. (reckon another 20 k or so and it would have blown) Admittedly these tyres were old but today we changed two 5 year old tyres from a well known Japanese brand (Jap tyres are generally some of the best) on a Commodore and both tyres were separating.
As we do a lot of older cars with the white walls and odd ball sizes we do replace some very old tyres including cross plys and knife them when we put them out in the scap pile to ensure they aren't taken for use. These tyres suffer mainly from sidewall cracking yet may have a lot of tread left. I saw a trailer the other day with sidewall cracks on the cross plys and the owner bragging they were 35 years old. I also hear various stories from people regarding storing of tyres. One customer buys his 4wd tyres 12 months or more in advance and leaves them in his shed as he reckons they get harder and last longer. As I am racing the Sunbeam less often now I sought advice on storing the race tyres (buffed Toyoy proxes) and various experts suggested placing them in large garbage bags and storing them in a cool room where the temperature doesn't vary much.
For those with 4wd's that have the spare tyres mounted on the rear door (Pajero,Patrol etc) It is important to have a cover on them or rotate the tyre 45 degrees every six months or so and if the car is parked for long periods turn the car so that the tyre is away from the sun. A very expensive tyre can get sunspot damage and become prone for a blow out when needed.
In short keep a check on your tyres and a vibration through the steering or drive train can be an indication a tyre is separating.
Also buy yourself a quality tyre guage as even those electronic ones at the servos are not always accurate. If you want to get it really accurate get onto one of the Snap On Tool guys for the Blue point guages. I did the research for a race team and these proved the best and around $70 is a good investment.
If you ever want to see a tyre delaminate quickly then fit a used directional tyre on the wrong way. It doesn't last very long.
With regard to retreads we sell only the cold caps for trucks and capped rally tyres for speedway etc. I was shocked recently to see a BA Falcon bought from a car yard in NSW with retreads. I had one separate in 1978 so never again.
One other thing to consider is the load index on the tyres. check that they exceed what is required for your car/van etc. The insurance companies take a good look at this when an accident occurs. New Hiluxes are a very high 112 which means a very expensive tyre to get it right.
If you have a query about particular tyres send me a PM and I'll endeavour to assist with any advice.

Article posted on behalf of Boblor regarding caravan tyres and how often they should be replaced.Note the comment that tyres bought new from a tyre dealership may actually be close to their 'use by' date when they are purchased.  (Source: Caravan World, August 2009, p 142)

Hi all, This item regarding the question of how often you should change your tyres over comes from Hardings Caravan Services' most recent newsletter (Winter 2010):  A somewhat sobering thought: "Whilst tyres are expensive the inconvenience of a blowout can be more expensive. The cost of the insurance excess on a wheel arch damaged by tyre blowout is more than the tyre cost itself, and repairing wheel arches has become a very common job at Hardings!" Don Ricardo PS This is not intended as an advertisement for Hardings - just some further info about tyre wear from people who probably see a bit. |

They are right. I have had two customers recently blow out tyres and done considerable damage to the mudguard are of the van.
It seems the tyres these days are not lasting like those of old either. Changed some 4wd tyres that were only 5 years old, still had good tread yet were badly sidewall cracked. (becoming more common and this was a name brand tyre also). I have my van in the awning of my shed but have put a cover over the wheel facing out so that the sun doesn't hit it directly.
