Avoid Cooper Tires Especially Discoverer at3

Those are a great deal. They are not severe service rated either but with how much you save getting them I am cool with that. I was going to get those for my Ram but never in stock on the 18s it seems like. I have them on my 79 F250 and had them on 09 Silverado 2500.

I think they no longer carry them, which really blows. I would've loved to get another set.

I definately want an LT tire and preferrably E rated also. After all, it's a truck, it should have truck tires, IMO.

They have been out of stock a long time but still have listed. I needed up getting Maxxis Bravo they were so cheap. Under $400 for load range E for my Ram 2500. Insane.

Been happy with Cooper Rugged Treks. Havent had them for long but I did tow 2x 750 miles with a loaded 6x12 enclosed trailer and then another 750 mile trip with a car trailer and a 3400lb car and they did great. I have no complaints with them so far.

Picked up a set for my moms car. Tires had great specs and were well recommended, but despite bing new with no leaks, they just constantly loose a ton of air all of the time. After asking around a few other shops, seems like this brand has a lot of issues these days. Might have to give them back and go another direction.

Were the rims properly prepared? Aluminum rims require wire brushing to remove surface oxide and pitting, and of course bead sealant prior to install. Quality preparation is essential to seal aluminum rims.

Probably has alloy wheels. They tend to get bead leaks with corrosion. Have to take off tires and grind off the corrosion. Many places are lazy and don’t clean them up and just put some bead sealer in. That works for awhile. On our 08 Yukon XL I just replaced the wheels I got tired of bead leaks and I figured they had given years of service already.

Could also be the pressure sensors if they have not been replaced.

It's a relatively new car under 25,000 miles. California car, very clean and installed at discount, who usually does a good job. Word from the techs was they are seeing a lot of defects on coppers, but the good ones are great. Luck of the draw I guess. My friends who go up to the mountains and play in the snow hate Nitto Ridge grapplers and love the cooper At3s.
