Please help me, I'm confuse about choosing a tire size. I'm planning to get the Azul Speed 6(http://wheelsnext.com/default.?action=dspWheel&MODEL=SPEED%2D6&color=BLA CK%20(GLOSS%20FINISH), they are 18 in. but I was confuse if I should get it with the Dunlop tire size 235-40-18 or with the tire size 235-45-18. By the way which tire size will be safer for the rims so that I wont damgae the rims? If anyone have pics of their tire size please post as much as possible so that I can get an idea of what tire size I should get. Thank you so much!!

235-40-18 should be the correct changeup size.

Mine with that size

I suggest you use this (or a similar) tire size calculator. This one will throw an error if the calculated diameter is off by more than 3% from stock (235/45/17).

It'll also show sidewall height, recomended rim size, speedo error, etc.

245/40-18 - Same OD as 245/45-17. 25.7"

Assuming that your wheels are 18x8 then 245/40 18 is the right size. If you want greater rim protection then you should get 255/40 18s, should rolling size should still be close enough. 235/40 18 wont give you much rim protection at all.
