BFG M/T KM1 - How old is too old?
« on: Jan 09, 2018, 07:38:30 AM »
So I recently bought a fj40 project that was someone elseís project and it came with a set of 35x12.5-r15 bfg m/tís

They still look new with nipples on them and I am told they have been inside most of their life but they still carry what I think is a date code of 2/2000.

I already have 37ís but do you guys think these are worth selling or are they trash?

It is an 18 year old tire. None of the big tires places will touch them to mount. They are prolly fine but would get rid of them. Off them for cheap

you have tires older than me
Keep it TOYOTA!

In the past years, I used to get a lot of calls from Jeep owners wanting to go slow like the Toy trucks.

The reason that I got rid of my last set of tires on my 4Runner was that they had crossed the 10 year line where Discount Tire would no longer touch them.  I ended up giving them to a friend in Colorado that is running them on a CJ-5 that is mostly a trailer wheeler.

If you can find someone to mount them for a trailer only rig I would have no issue running them because a tire failure off road is fairly low risk, but street use significant increases you risk to personal safety.  I drive mine cross country so wasn't willing to chance it.

I am definitely getting rid of them, i already have 37's. they just look so new i am having a hard time junking them. I plan on selling them with the rims they are mounted on as they are 15's and i have no use for them but what do you guys think price wise?

400 bucks with rims for offroad only?

I wouldnít take any money for the tires. Advertise for the wheels with free tires. You donít want any legal connection to them in case the next owner thinks they are awesome and decides to run them on the street.

that is a good point.

you think 100 bucks a rim would be a good price then?

it is surprising though they are not weather cracked at all seeing as they were inside for 16 of the 18 years, dirty but look like they would have came from the tire shop.

I ran gateway buckshot n78-15s on my rig when I first got it. The guy I bought it from was the original owner with no reason to lie. He said those tires were purchased in the late 80s and ran during hunting season every year and then put back in the shed at end of feb. I sold them tires 4 years ago and the guy that got them was happy as could be to get them. Talked to him early this season and he is still running them on his hunting truck. Granted these don't get daily driven. Maybe 75 miles to the camp then all season around there then home. I have zero concern running old tires on a rig. I don't know if I would make a long journey on those bfgs but I would not feel bad at all purchasing them for $400 for use on a toy.

I believe they start to degrade from the inside out.

Not trying to start a gnarly style debate, but have you ever seen the inside of an old tire? I have seen many old tires dry rotting and cracked on the outside and inside still look fine with no separated belts or anything of that nature.

Inside as in internal and not just the inside surface.  I absolutely could be wrong, but when I replaced my tires I did a bit of reading and my understanding is that a tire can degrade to unsafe levels without exhibiting obvious visual cues.

They are an oil based product.  The oils evaporate over time and the tires lose their integrity.  I canít tell you how many stubborn old men have come back to the shop with a hangdog look on their face after a tire we told them was too old for service blew out.  As has been suggested, I would strongly discourage selling them
