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.

Well I have learned a lot about tires. Thanks!

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$$.

Big O Bigfoot and Cooper Discoverer were both mentioned in the initial post and Bigfoot is reportedly made by Cooper, but which Cooper tire is it? Or is it a one-off uniquely made for private labels? Big O tells me Bigfoot is a much better value and I am just paying more for the Cooper name if I buy the Discoverer, but they will get it for me if I want. I do want the E load rated version. I have the Cooper Discoverer AT3, NOT  light truck or E rated, on the Tacoma now and really like them. they have little tread left and have worn evenly.

Bigfoot is the house brand, made by Cooper, for Big-O.

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.

Ski3pin, any further comments on the Coopers now that you have a few miles on them?

 

Thanks,

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.

 

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.

Ski, Great to know. Were you aired down? I have the Cooper S/T  Maxx tires now and so for I like them.
