For a given tire manufacturer, the capability to operate with the additional inflation pressure rating of a load range E versus a load range D tire generally results in a stiffer tire carcass. The tire has to be built stronger to handle the higher inflation pressures.

how many miles did you get out of your first set? i have driven a dually with them on it and they were great in the snow. i cant complain about the nitto terra grapplers in the snow or ice they have done great. i just think they didnt last long enough. all of the reviews i have gotten on the BFG TA KO's have been good.



I did a good job on air pressures and maintaining appropriate levels. Rotation and balance? The only balance was when they were factory balanced for the H2 they came off of. Rotation occured one time. The fronts have some tread left but are thin. The rears are down to the wear bars. Given this ill treatment, I got 50k out of them.
 
I’m coming up on 100K. I wore out the original BFG Rugged trail and a set of BFG KO’s (285-70-17’s). I also towed with the KO’s (9,000 lbs gooseneck) and the KO’s worked great. Snow traction was awesome (no chains, driving through 2’). The only issue was I had the radial pull so I needed to play with the rotating or she pulled to the right. I got around 40,000 out of the KO’s. Because of the pull and desire for better mileage, I went the E rated 285’s in the Toyo AT. The pull is gone, snow traction is decent but the ride is harsh compared to the KO’s. With pulling, the KO’s actually felt better and the Toyos empty, besides being harsh, are squirmy compared to the KO’s. The harshness is particularly evident when off-road. I’ve got about 10K on the Toyos so this will be a while before I need tires and I will go back to the KO’s. If hauling heavy, look at your rear axle weight and buy accordingly. Hoping this sheds some light for those stuck in the middle.
 
I had set of Cooper Tires installed while traveling out of state. By the time I got back home (2000 Mi. ) the vibration was so bad above 50 I could'nt stand it. I took it to a Cooper dealer. He said they were slightly out of round and he would fix them by grinding them back to round,which removed about 25% of my tread. That helped some, but still was'nt right.

After another 6 or 7000 Mi. the tread de-lam. in the Az. dessert (110 degres) and that was the end of my ***. with Cooper Tires.

I did promise myself I would tell this story to anyone interested in Cooper Tires.

This was several years ago but, the burn is still in me.

i got about 18000 out of some 35x12. 5 cooper stt mud tires

versus 40,000 to 50,000 out of my 35 bf goodrich mudterrains and that is on the same truck 03 4x4 quad cab long bed
 
I've had pretty good luck out of the Coopers I have bought. I did have a set under the recall though.



On my 91 - Discoverer ST

1st set - 40,000mi

2nd set - under recall, around 10,000 mi when recalled and no problems

3rd set 8-10,000 mi and still looking great, no appreciable wear



Getting ready to put a set of the ST's on my 01 also.



My sister's truck (98 in sig) has about 10-12,000 on the ATR's and they seem to be holding up pretty well.

My Coper Discovers went to the junk pile when one of them seperated at 31k. Never lost any air just fell apaft (seperating they call it) I looked at the numbers and they had all been built near the same time. $2,000 damage to my left front. Then I noticed there was 16 oz. of lead to balance the wheel. Michelins hardly require any weight to balance and they are ROUND. I found the J. D. Powers report on the internet and it said a survey of over 500 tire stored in the midwest revealed that Michelin was the only tire that had not had a complaint. All the rest had complaints. Michelins were available with "E" rating so that is what I got.
 
You get what you pay for I guess. The Michelins are pricey buggers but, undoubtably excellent tires. Unfortunately they don't offer a good snow tire in our size. I have run LTX M/S and LTX A/Ts and niether is as good in the snow as the BFG AT KO or the Wrangler.
 
Can anyone explain this? I was thinking about a set of Mickey Thompson Baja Radial MTX in 33x12. 50R17. Just for laughs, I called about the Dick Cepek Radial F-C II. They said they won't fit the stock rims as it required a rim width 8. 5-11. The MT's only require a 7. 0-10. 00 rim width. These tires are essentially identical in every aspect. Why the difference in rim size? BTW, my buddy ran the MT's in the oil patch (yep, mud and northern clay gumbo) and they performed very well.
