Just wondering about wheels and tire combos for a 2004-up Mazda 3 GT. Am I correct 16" is the smallest rim size you can put on a GT with the 2.3L engine? And for summers if I went 19" wheels, what is the max tire size one can put on the car? I was looking at a set of 245/30/19 tires, but not sure if those are too wide to fit. I suspect the 19" wheel will have a lower offset then the stock 52mm offset. Maybe closer to 40 or 45. Other possible tire sizes would be 215/35/19, 225/35/19, and 235/30/19. Which one is the widest you can go with?
