You have a very nice looking SUV! I like it a lot! Like you said 24's is a personal opinion. Seems like its just one of those things you have to try it for yourself to really know. I think because my wife will drive this more than I will as I have a Lifted Avalanche, the small tire that will be put on the 24's she will probably scratch the heck out of the wheels because well, I love her and bless her heart but she does hit those curbs and I am not sure if those 305/35/24 will be enough tire on there. I had an infinit Q45 with some 19's and a small tire and she drove it, got a flat and had no clue she was rolling on a flat tire. When she got home she mentioned the car was a bit bumpy and I went outside to look and the tire was cut all up. Lucky she did not scratch the wheel so it must have just happened. Maybe 22's will be better....
So you did not like your kmc slide wheels? I have not seen anyone around where I live use them. I have seen some youtube videos of them rolling and man do they look sweet!! I had one test fitted the other day and I will say that it made my jaw drop on how much better it looked compared to my stocks....
