It's good to see some through testing using a big Mopar, instead of a newer lighter car. I'd like to see the tires in a 255/50-17 or 255/45-18- ie 27" dia. For a driver car NVH is a factor as is wet handling and to a lesser extent, tread life. I'm not expecting super long life on my TW 260 Nitto Invos, but they are reported to be quiet and handle well wet and dry. I can accept a rumbly exhaust, but loud tires annoy me to no end. If I get the bug for autoX I'd probably get a set of dedicated tires for track only use.
