hi, not to rain on anybodys parade, but... Eagles are very sensitive to tire size changes, most of the folks here who run non stock wheel/tire combos succsessfully , done the math, got the height correct, etc. There were two "Stock", sizes for Eagles. the base 195/75-15. and the "Sport/Limited" size 215/65-15. If you go anywhere above this size, with a stock drivetrain, your eagle will be slower, less responsive, etc. Again, not to belabor the point, but an Eagle is NOT a Jeep! An Eagle is a ROAD car! I have been driving Eagles for over 20, yes TWENTY, years, maybe closer to 25, and I have never felt the need to go past the 215/65-15 size. An Eagle with this size tire and a good stock suspension will drive through 6" of snow without spinning a tire! We used to live at the bottom a hill, about a 30 degree slope, occassionally we have ice storms here in Virginia, the road becomes a sheet of ice, best stay home, no regular cars can move, even Jeeps, with all those big tires can;t get anywhere, but the Eagle, with it's "soft" style of all wheel drive, and regular All Season 215/65-15 tires motored right on up that hill, on ice, I am not exagerating, I am not making this up. I used that Eagle to get stuff from the grocery store for all our neighbors till the ice melted.
Point being, appreciate what you have first, before you decide to reengineer the car. good luck, y'all, gz
