I'd never heard of the use of cotton plies. I think I see why. In the 1930s rayon replace the cotton in cord belts. In 1943 nylon cord was introduced; steel-cord in 1959 and fiberglass cord in 1963.
As a design engineer you learn pretty fast that standards last forever. I had a long, convoluted story that I told to newby engineers when they would question why we were using an awkward standard about how the diameter of the first stage of a Saturn rocket booster was determined by the width of a 1st century Roman war chariot horses a$$.craig333 said:I'd never heard of the use of cotton plies.

Interesting.ski3pin said:
But is it identical to one of the Cooper models and if so, which one. Or, is it a unique model manufactured just for Big O? I guess what I really want to know is if I will get a better tire if it has the Cooper name on it vs the Bigfoot name? I know that some manufacturers of high quality products make an inferior product for private labels by using cheaper materials.Ace! said:Bigfoot is the house brand, made by Cooper, for Big-O.
Four years ago, with an almost new set of the BFG all Terrains (the subject of this thread critique), we drove an extreme road down into a remote canyon in Nevada. On the steep 4x4 low crawl back up I was at the edge of traction with the BFG's.cwdtmmrs said:Ski3pin, any further comments on the Coopers now that you have a few miles on them?
Thanks,

Yes, both timescwdtmmrs said:Were you aired down?
Wouldn't a better comparison be the KO2? It tested as having better traction than the KO and is severe-winter rated.ski3pin said:Four years ago, with an almost new set of the BFG all Terrains (the subject of this thread critique), we drove an extreme road down into a remote canyon in Nevada.

A couple of weeks ago we again drove this road with our almost new set of Coopers. The road is now in much worse condition. Driving back out, I was very impressed with the new tires.
This was a good real world comparison of the two tires for us. The BFG's were good. The Coopers are better and I am impressed with their performance.
Which Coopers?ski3pin said:Yes, both times
ski3pin said:We have put over 100,000 miles on our truck with camper. Check our blog stories, I believe you'll find a well rounded set of travels - mountains in winter, the high passes in Colorado, the legendary roads in Death Valley, and a bunch of others we keep to ourselves.
I have wanted to love these BFG tires. So much so that I ran through two sets on our truck, close to 80,000 miles. Based on this extensive experience, please allow me to offer a very personal review.
Things I liked about the tires - they did well on dirt roads.
Things I did not like about the tires - they were poor in mud, mediocre in ice and snow (we live in the snow), poor thread life (barely reached 38,000 miles each set), noisy and got noisier as they wore.
If this tire went to school, here are the grades I'd give.
Dirt - B
Mud - D
Snow & Ice - C
Thread life - C
Quiet/Comfortable Ride - C
Overall, I give this tire a very strong C .
An idea on other tires I have used over the years - BigO Bigfoot, Bridgestone Desert Dueler, Cooper Discoverer, Toyo Open Country. My favorites from this bunch were the Cooper and Toyo.
Yesterday we put new tires on the truck and went with Cooper Discoverer ATP
Why we went with Cooper? I liked them in the past and personally spoke with people who drive on Coopers. They certainly looked like they were worth a try.
My critique of the Coopers will come after I've got 15,000 to 20,000 miles on them, if anyone has interest.
I just did a tire rotation on the truck and noticed I now have 20,000 miles on the Coopers Discoverer ATP that I moved to after the two sets of BFGs.ski3pin said:Four years ago, with an almost new set of the BFG all Terrains (the subject of this thread critique), we drove an extreme road down into a remote canyon in Nevada.
