hello there. I have set of volk rays g25 dark prism for my 2015 is350 f sport .
rims size front 19x8.5+35 and 19x9.5+45 rear. I might get coilover late on so I need some good suggestion for tires so even if I put coilover later, I just don't want to deal wth rubbing

I was thinking about 235-35-19 front and 255-35-19rear

 

The matching rear tire size for 235/35/19 would be 265/30/19...and by matching I mean relatively the same circumference.
The 265 would give you less sidewall height to make sure you didn't rub on anything since you have the +45 offset in the rear.
Although the 265 is a tad wider.

What about 225/35/19 front and 255/30/19 rear? Or do you want more sidewall all around?

 

Yeah I don't want to deal with rubbing so I will go with 265/30/19. Thank you so much
