finally get 19' breyton flame rims, they are 8.5 in front and 9.5 in rear. The offset is 30mm. lug pattern 5x120 front tires are new 235/35/19 but need rear tires. my question is what size do i need i can get some 255/35/19 for awesome price but will they fit can also get some 285/30/19 for about 80$ more each. id much rather spend less if the 255s will fit but please help btw i have a 2004 530i sport. thanks in advance

 

I think it looks funny with a taller front profile than in the rear. I had 275/30/19's out back with 245/35/19 fronts for one day and swapped them out for 285/30/19's. 255's will look worse IHO.
