Quick qestion about tire size
 

I have a 2000 bmw 4.4 x5. i installed some 19" hartge classics on them. the tires sizes i have on them right now are "front 255/50/19 and rear 285/45/19". i wanted to know if i can go bigger on the height part of it. i would like to run 55 and 50 if possible i dont want to mess anything up please let me if this is possible, i want to the ride i had with my 18" wheels back.

btw if anyone is interested i am selling the oem 18's style number 56 with tires which have at least 90% tread on them

WE only guarantee the sizes you listed, and do not have any "taller" fitments that would change the ride quality enough to be noiceable. Sorry
