Hi all,
This is a warning to all Toyota 80 & 100 & probably 200 series owners.
If you have BFG A/T tyres then beware.
Because it is very hard to puncture one of your tyres it may be years before you have to wind the spare down to use.
I have just found the security bolt on our 80 to be impossible to turn to allow the cranking shaft in to the wheel lifter and I had to drill it out and use a screw extractor.
All this caused by those BFG tryes that I have not punctured in 9 years and haven't lowered the spare for maybe 4 years.
My advice is to wind the bolt up and coat it in a light grease so it won't corrode in place and retighten.
We had just been away and luckily had no tyre trouble.
Ian

Ours only gets used for bush trips. It is only a 2 seater now with the drawers and 80 lt waeco in the back. It is not good to drive around town so only goes bush.

So I hazard a guess that you haven't checked your spare tyre pressure for 4 years as well.

My spare is regularly removed from the underslung storage position so I can check the tyre pressures, but then again I am still running those POS Cooper ST's hahaha

Kev,
I check the tyre pressure only by feel and if it was ever used would check and adjust it when I put it on. I do hear what you say though.

Put some grease on the thread and add some dust and then try and wind it down.

Keep it clean and try as Kev said wind it up and down on a regular basis would possibly work better.

Mine is checked and the tyre pressure adjusted before every trip. That tyre carrier is a diabolical design, no doubt Toyota's revenge on young players.
But I now also have a rear carrier.

I've had a bit of a search on this site for a reference but I can't find one, but I'm certain that there has been a lot of comment on various sites and blogs re. the ageing of tyres.
Current wisdom dictates that 6 year old tyres, i.e. from the date of *manufacture*, should be considered as no longer serviceable due to the volatile compounds which add adhesion and elasticity evaporating from within the rubber.
If tyres have been exposed to extreme temperatures and rough usage, then de-lamination and other structural failures can occur much earlier
There are normally no visible indicators of this deterioration.

I never said they were the same tyres for 9 years but they all have been BFG A/T.

:D But it's worth the "heads up" to alert those who, like me, are "parsimonious in extremis" and try to get the last ounce/gram out of everything.
There are some very expensive savings to be made ;)

Why are you picking on BFG.

Surely it doesn't make any difference what tyre is on the carrier.

If you are careless or stupid ( cross out which does not apply) enough not to check your spare occasionally the same thing will happen regardless of make or tyre size.

Keep it clean and dry is best grease only attracts stuff to stick to it.
Use it more often or Murphys Law will apply at most inconsiderate moment.
To me this is an unnecessarily inflammatory post which is not really about the heading at all.

I have a set of these in the shed to go on shortly and thought O God what's wrong with them now.
Answer Nothing that preventative maintenance wouldn't have fixed.

Graham, maybe the Qld sun is getting to you.
It was "tongue in cheek" from the start pointing out the need to check the security bolt which I had not done for years because I haven't had a BFG puncture for years.
Cheers, Ian

Instead of grease chuck some molybdenum disulfide dry lube (or similar) on it as it wont attract dust and dirt.

Yup! Or old fashioned graphite powder or even selley's ezy-glide.
At a push even a coating of cheap baby-powder can be helpful.

You are a lucky guy!! Often when Toyota owners go looking for their spare, its either broken off and missing in action or punctured by something they have driven over.... Michael

I have heard from similarly afflicted owners that Lanoline spray works a treat for that application...... nice plug for BFG though
:-o) ...... seems you've got away with it !

Lanolin is really bad for attracting dust. We used to use it on a cockrell spreader and had to jetwash it off again after every use due to the dust attracted to it making it hard to operate. But it did stop it rusting.

Another smart idea would be to rotate the five tyres at every 10,000 k's if you follow a servicing schedule.

Not only do you eventually get extra k's out of your tyre set and therefore delay the purchase of new tyres just for a little longer but it just might stop the worst case.

That would be when you are stuck in the middle of nowhere and have snapped off the bolt to get your spare tyre.

Just a thought.

Yes that is a good idea but.... I have 265/75 16 on the road wheels and a 235/85 16 as a spare. They have the same rolling circumference but the 235 is 30 mm narrower than the 265 and so does not hang down like normal 80 series spares. With a 70 mm lift the spare is behind the rear axle housing and high enough not to not drag on anything. There is method in the madness after all.

I hope to go out and do some off track stuff again this year and in the interests of totally unbiased and impartial assessment, I hereby volunteer to try out 7 BFG A/T's or Muddies at someone elses expense. Tyres must be 285/75 R16 and new. Please deliver to Victoria. I will make a thorough assessment and report at trips end. Same offer applies to Coopers or any other brand someone wants to provide for me to destroy in the Great Sandy, Gibson or other desert of my choosing.

Any donations or round black rubber things greatly apreciated. The sacrifices I'm prepared to make for this forum I tell you!

Cheers Mick.

Yeah Mick life's tough and somebody has to stand up and make those much needed sacrifices.

Tell you what if someone does donate a few tyres for your next trip then I'm prepared to help you out by coming with you to help change or repair them when they go flat :-))

100 & 200 series don't have a security bolt like the 80 series does
