I've been running the 420S's on my '02 Range 4.6 w/ 18" wheels...
I absolutely love them!
I use these for my all around driving, and have another set of tires/16" wheels for offroading.
When i bought the truck, it had the factory Michelin's on it, and these were a significant upgrade. Reading the description of the tires they claim to have a stiffer outer sidewall for stability, and I can personally verify this from experience. The Rangie holds the curves much much better.
I can't remember if they have a mileage warranty, but I'm around 40k-45k miles on them and the tread has worn perfectly. I know I should have, but I've never even had them rebalanced since they were first mounted 2 yrs ago. I just rotated them on my own. It's about time to replace these, and I'm gonna get another set of the 420S's. I just can't say enough about these tires.
Good luck, and if you do get them, please reply with your impressions of them.
