Alright guys, i'm looking to get some new shoes for my Mazda 5. I'm currently still rockin' the OEM wheels...

Sorry, for the huge pic lol

Anyway, they are currently 17's on 205/50's. They came that way from the factory so I know the wheels aren't that wide since they are 205's on some 17's...

I can't find any fucking website that will show me what off-set these wheels are but it kinda doesn't matter since I wanna throw on some 18's and I know when you go bigger you don't use the factory off-set but knowing the factory off-set would at least give me a starting point when choosing my off-set, correct?

I don't want my wheels sticking out like a fucking beaner. I want them flush-looking with the fender and quarter panel. I'm getting rims strictly just for looks so the thinner size I can get some 18's in, the better, that way I don't have to worry about them rubbing when I turn.

I'm more or so leaning towards these...

I'm looking to get them in 18x7.5 but need help choosing an off-set. Is a 215 tire wide enough for 7.5's or would I be looking more towards some 225's? I will also be running them in 45's... 40's would just make me feel more of these shitty ass Cali roads...

Any help and links to wheel info such as wheel weights, off-sets, and lug patterns would be great :)

Oh, what is the rule of thumb on off-sets when changing wheel sizes?
 
Thanks B. Fuck ask.com, I couldn't find shit using them... it's google from now on lol.

So from those pics 18x7.5 w/ a +45 or +48 off-set is where I wanna be...

Also I meant 'rubbing when I turn' by the inside of the rim/tire rubbing the inside (towards the engine) not rubbing the fender lol... sorry for not being more specific...

Another question, what if I decide to go with a rim that has like a 2 inch lip? Wopuld I still be looking for the same off-set regardless of lip size?

that depends how the wheel is made.

i doubt you're going to find anything with a 2" lip with that offset in a 7.5 width though... it's simply not big enough.

ok, that makes sense. i've been reading on that Mazda forum you linked me to and it seems like i'm gonna have a problem with the TPMS. Unless I can just swap over the factory valve stems onto the after market wheel...
