ok so i have a 2007 mazda3 sedan that is lowered on megan springs. im looking to get some 18's and im wondering if i can run 215/45-18's and not rub or stick with 215/40-18s. I really dont want to have to roll my fenders. thanks

215/40 is perfect.
You'll be fine. Im on 225/40 and Im lower then you and i don't rub

sooo.... should i go with a 215 or a 225 lol. what would look better in your opinion?

215/45/18 is the OE size on Gen1 MS3's, so I think your fine.

even with being lowered?

I don't see why not, depends on your offset. Possibly may have to roll the quarters depending how far out you are. If you are real concerned, you could go down to a 215/40 for a slightly shorter sidewall. A 225 is a slightly wider tread. Click the link below and you can compare the sizes on the calculator.

you might rub a little. i know when i had 225/45/18 it would only rub if i hit a bump other than that nothing major but. i was also tire tucking lol
