I finally bit the bullet on purchasing these tires, 245/45/20. They are absolutely what the doctor ordered for these 2 ton plus Chrysler LX/LC platform vehicles. The handling, ride comfort are excellent thus far. There is more sidewall flex than I was expecting, but nothing that presents an issue. I'm experimenting with the air pressure for now, which is now at 34psi F&R vice the OEM 32psi which is not suitable for this particular tire on this vehicle. I have moderate power over OEM levels with 370rwhp/410rwtq along with a full Pedders LX Track 2 suspension. Overall these tires allow you to keep pulling with exceptional lane changing and speed burst control in both the dry and wet. As of now, I will purchase these tires again when the time comes. I'll remember to post an update at the 3000 mile mark.
Note: Michelin really needs to re-evaluate their pricing in the 245/45/20 size. They are too many vehicles that have this size, like the Chevy Camaro SS, Chrysler 300C, Dodge Charger, Magnum and Challenger R/T and SRT models. Just a thought.
