I can't speak for that particular Cepek tire but I had some Radial FC's for a VERY short time a while back. They were BALANCE_PROOF . 345/65/16 tires, one had MORE than 14 ounces on it. The vehicle shook violently above 30 mph. I took 'em back as fast as I could drive without breaking the vehicle.
So, to read between the lines, I don't care for Cepek tires. They do "Look Good" though
