rims & tires, what sizes do I need? Options

[dayzdchika]

I want to get some rims, but I don't know anything about the different sizes in rims & tires, like what will fit on my celica. From what I've read, I think I want 17's, because if I understand right, if I try to lower the car, 18's will cause problems for me. I don't know anything about tire sizes, like what the 3 numbers stand for, so what would I need? And as far as brands go for the tires, is one brand better than another?

thanks guys!

if I got 17 inch rims, how much do you think some decent tires would cost me? and what size tires would fit on the 17's? I guess it would be 205/something/17, right? but don't they have to be low profile tires since the rims are bigger than stock?

btw, I think my wheels right now are just 14's, cause I have an st, and I was told since I have hubcaps, they're smaller, just 14, instead of 15
