I wouldnt feel safe driving either one of those rides. 1 good pothole and your looking at a new rim and tire. I rode 20's for a month or so and went back to 18's, but to each his own
arent the 2000-05 or 06 montes the type of frame as grand prix??? i know 22s will fit a monte.... a lil rub'n in the rear with big dips in the road tho
I would do nothing but 18's and a drop. There is a pretty sick one around my town on 18's and a drop and looks good. I am not sure how well it rides, but looks good.
mehh on my impala i got 22's with 30 series tires and they ride good to me. Hit many potholes with no problems. Now if you get a 245 or 255w tire on a 10" wide rim then yeh you hit a pothole and you're done. But my rims are 8.5" wide with a 255 tire so it isn't stretched out at all.
And yeh for the grand prix you should be able to fit 22's if it is indeed the same frame as other gm models of that year. **** i seen a 00 impala tuckin 24's riding lower than stock height
