Blowouts With BF Goodrich Tires
One after another all of the BF Goodrich 235R8516 tires on my pickup have blown the tread off in catastrophic blowouts on paved highways in Mexico.
The unit is a single tire one-ton with a weight of 6,500 lbs. Tire pressure is carefully maintained to 70 lbs. Front end alignment is perfect. The
unit is not driven faster than 55 mph ever. Tires had a minimum of 8/32" of treadwear (even). All tires were spin balanced and were less than 3 years
old.
I have in excess of 150,000 miles accumulated driving in Mexico and have NEVER had a blowout until the Goodriches.
I have lost confidence in the brand

I'm not familiar with the 235R8516 but 70lbs pressure seems like a lot. If that's cold then it would be 5 or more when hot. I run LT285/75R16 TA KO at
45 front and 30 rear when unloaded and 40-45 rear loaded on a GMC 2004 Z71.

Is it a TA KO ? There the best tires I ever had. Who or what made you run with 70lbs.

That is the basic Load range E tire he's talking about, I'll wager, based on the size. It's rated up to 80 psi. Keep in mind that even if he adds 80
while cold, the tire is made to take the expansion beyond that.
Doesnt surprise me a bit from BFG. They have a history of churning out bad batches of tires, from what I've seen. I had a buddy who lost three within
two weeks; two on the same trip. All highway. Those were TA A/Ts. Tread separated longitudinally between the treads. BFG refused to call it their
problem. I wont own them after that.
Here's what I'm running. Michelin LTX MS. 48, 200 so far with a 6800# truck and a 2500# Lance on the back for probably 70-80% of driving. ONLY TWO
ROTATIONS.
Remember, the true cost of tires is cents per mile driven. The Michelins are probably more expensive than the BFGs but they wear like iron.

If it is the TAs you are exceding the max cold psi by 5lbs. I have a full set (6) BFG MTs 33 x 12.5 on my Bronco that weighs 5900 lbs and I run them
at 35 psi. I have seen psi increases of over 10lbs while running in Baja. Depending on outside air temps, the pavement can be 150 degrees + and its
way rougher then anything state side, oh, except for the pot holed, falling apart paving in my neighborhood. But that's a whole nuther topic, sorry.
I don't see that you crashed your rig during blow out, which is thankfully good. Not to diminish the trauma of the experience in any way but I think
you were way overinflated. BFGs have a nice stiff side way and don't need that kind of psi. Depending on size and application many of them have an E
rating.
I would also suggest purchasing future tires at Discount Tire Co., no association here, just a satisfied customer, and buying the road hazard
warranty. Flat a tire and ya get a new one.
I just replace the tires on my F250 utility bed, work truck at Discount. I had stupidly got talked into a set of Pirellis and they were balled in
35K. They gave me $62 back on each tire. I didn't feel as stupid

Hook beat me to the post. See how easily confused we can make you? Before I posted I went out and looked at the TAs on our Grand Cherokee and they
are 65 psi max cold FYI, FWTM

The door sticker of most any 1 ton pickup would require at least 70 PSI. I had to buy a new pressure gauge for my year 2003 3/4 ton because it didn't
go high enough compared to the pressures in my 1995 3/4 ton.
Note that DavidRe (who I do not know) says his unit is not a dually. Tire pressure is based on square inches of rubber on the pavement divided by
gross vehicle weight, if I remember correctly. 70 PSI would seem light for that rig, except that DavidRe didn't mention that it was heavily loaded.
Sounds like a tire issue to me, without knowing any other facts. I'd be making a call to BFG and sending a letter to the CEO if I didn't get a
satisfactory answer as to why the tires failed, but I certainly wouldn't just cry in my beer.

The BFG All Terrain TA spec sheet shows that the E-rated 235R8516 is good for 3,042 lb weight rating at 80psi EACH. Clearly, a 6500 lb truck on four
of these little devils does not require 70psi. A talk with BFG for a more reasonable pressure recommendation might be in order.

You cant say that without knowing whether his load is approaching that.
Even so, running those tires at 70 will, in no way, adversely affect them without some kind of manufacturing problem. That's still some serious aire
that would only serve to run the tires cooler than lower pressures.
Lower pressures might be called for if he's not carrying weight but it in no way explains the problems he's had. We're talking load range E tires
here.......they should take it.

Mas Info
The tires are the "commercial" BFG. The sidewall info indicates a max tire pressure of 80 psi. The tires were installed and spin balanced by Costco in
El Paso. I quaified my tire gauge against an identical gauge as used by the Costco technician. Both were within 2 lbs of one another. The greatest
weight I carried was when I was coming south. A commercial truck scale measured 6,500 lbs with both fuel tanks filled and me sitting in the cab.
I checked the Costco in San Lucas, and they do not carry the 235R85 X16 load range E tire size. The closest is a 245R70 X 16 in both Michelin and BFG.
These tires are close in height but are three inches wider than the 235R85 tires. I checked back with the tire shop and they said that they had called
Tijuana but found no correct size tires.
Yes I did opt at time of purchase for the road hazard warranty. But it does me no good at all when I am a zillion miles from a US store. The shredded
tire is dangerous to human body parts as well as to the camper and truck. The steel cables make grappling with the tire just as hazardous as fondling
a jellyfish.
I cannot access Costco from down here. An unhelpful email answer simply said "Contact The Store Where You Purchased The Tires". Can I slice off a
section of the tire that shows the problem plus includes the serial number, or do I have to haul the whole carcass back to the states?
Aye! Maybe it's time to sample a few dozen Tequilas 
Thank You Folks!

I've mentioned too many times previously that I will no longer use BFG All-Terrains. Multiple instances of sidewall blowouts with the tire sizes I
was using on my Toyotas.
I've tried many other brands/etc, found winners in the Bridgestone Dueler line and see no reason to now change - at least not yet. Things always
change though.

Can someone in the states call a Costco warehouse and ask the tire folks if a "whole carcass" is necessary in order to make a road hazard claim? I
cannot access US information down here.

70 psi would be way more than what I'd put in my tires, off HWY or otherwise. Factor in the heat expansion etc. you might be rolling on bombs.

70 psi is not abnormal for any 3/4 or 1 ton truck with e rated tires. The truck manufacturer recommends that as a normal pressure. Underinflating
tires on a heavy truck can cause severe tire failure.

Davidre, are you saying that the Costcos in Mexico will not honor a warranty purchased in the US?
Or is it just that they dont have an exact tire and the warranty only applies to an exact exchange?
If it was me, I'd see if they will apply the prorated warranty to a tire in their stock. Sounds like too much hassle to try and deal with a US Costco
from down there.
If you have already moved all your gear down, you probably dont need load range e tires anymore; you could get away with some Ds. Are those more
available?
David, I have an ex-student that manages the tire portion of the Costco near me. I'll call tomorrow and see what it takes to verify the warranty. I'll
bet the whole carcass will be the answer.

I bought a set of 4 Of BFG TAs and 3 through the tread and the forth I thorough in the trash after bfg would not honer there woranty. I will never buy
another BFG. I have gone to Firestone and bridgestone and the tires are very good. they cant afford to put out another bad tire.

Hook,
I had pair of those Michelins and got over 50,000 miles on my F250.
They were great tires !
I'm actually needing a new set for my F350 crew and I'm considering either the Michelins or Toyos. My last set is Schwab Wild Country 285/75. The D
rating is the same load as an E rated 265. I'm looking for more of an all season than off road tread. Ford sells them with 265's but it seems like the
285's are a bit better ride and better in sand ?
Anyone have any recommendations ?? For size or brand.

¡Mil Gracias Señor Enganche!
Costco Mexico does not offer (nor honor) a road hazard warranty to the likes of the one available in the USA. Secondly, COSTCO (nor anyone else I can
find) has the 235R85 X 16" load range E tires.
What I CAN find are 245R75 X 16" load range E tires that are three inches too wide for the wheels. This means that even at 60 psi, the center of the
tread is going to wear horribly fast. Wider wheels are not an option unless I want to spend an additional three hundred dollars for "custom" wheels
that apparently are not made to carry anything near the maximum load rating of the tires. The wheels also do not have "coined"holes for the wheel
studs meaning that the lug nuts can come loose at any time. The weight of the truck will not allow me to choose eight ply tires and even then the damn
eight ply tires are an inch and a half taller than the ten ply tires (go figure!).
I am going to hate having to spend seven hundred and fifty dollars for tires that have to be thrown away.
