@lincolnlocker I won't say that I am dead set against Cooper or their sub brands. But essentially not coming with a warranty is a mark against them that make other tires look like a better deal. It is hard for me to think back to something that I have had to use the warranty on, but defects happen to any brand. I have no specifics on what brand, model, or application of tire, just the blanket statement of "Treat Cooper and their sub brands as if they don't have a warranty. We have had issues with getting them to back their warranty lately". If you have a cooper tire that you think would hands down be the best tire for what I have tried to describe I would certainly consider it.
The father-in-law mentioned he didn't like Mastercraft before the recent warranty issues as he didn't have good luck with them. He had an anecdote about them that I am taking at face value as a tale of oddity and caution but not severe enough nor enough information for me to swear off the brand. Didn't specify when it happened but I believe his story went something like this:
Farmer bought 2 new tires (model never specified) for the rear of his truck as he had two that had worn but two with decent tread still. (As farmers will do). Tires were correct size and load rating, balanced, inflated to door frame pressures (as is required by some of these shops), and other normal procedures for any tire installation as he had been doing for years. Customer was sent on his way. Customer came back saying he couldn't explain it but the ride got way worse and insisted the father in law test drive it. Father in law described the ride to be similar to as if he were driving on marshmallows instead of tires. Not that the ride was smooth, but like the sidewall had so much give that corners we unnerving and he wasn't sure how the bead stayed on the rim. Brought it back, tried some different tire pressures to no change. Finally called up Mastercraft to see about a warranty claim. Mastercraft pushed back and told him the tires needed to be installed on the front of the truck instead of the rear. Fought with them over it a bit but got nowhere. Ended up giving it a try and the problem seemed to go away. Farmer was happy enough and kept the tires on the front but it never sat right with the father-in-law.
