2010 Mazda 6 iTouring
This trim is offered with the 17" alloy wheels however, I'd like to put stock 18"s on it. Is there any reason why this might cause a problem with the TPMS? Is there a difference in the way the iTouring is engineered compared to Grand Touring S? Suspension or anything? Or will it be perfectly ok for me to swap out my 17"s for stock 18"s?
 
Incase this info. might help someone, the answer to the above question is: no. My dealership attempted this for me but these wheels have different offsets.

EDIT

Sorry, I thought I was responding in another thread I started about putting Mazda 3 wheels on my Mazda 6. My mistake. This explains why none of this makes sense!

sorry, but that doesnt make any sense at all. if the wheels were made for the same car, they should be a direct bolt on replacement.
 
I can't think of a reason why the larger stock Mazda wheel wouldn't fit. Even if it is a different offset, it won't be so different that it won't work. I could see a problem with downsizing if brakes are different between trim levels....otherwise you should be good to go.
 
You guys are right. I was referring putting 2010 Mazda 3 wheels on my 2010 Mazda 6. My mistake!
 
Putting the 18 inch(stock) on your M6 is no problem, just bolt right on.
 
Offset Mazda 6 187,5 wheels?

Hi everybody!

Since I drive a Mazda 5 this may be the wrong forum to post in but I try anyway. The thing is that I want to know what offset Mazda 6 187,5 stock wheels have. I want to fit them on my MS5 but I'm not sure it will fit. The size and offset on my wheels now is 176,5" and 52,5 mm offset. I posted The same question in the Mazda 5 forum but haven't got any answer there about the wheel offset. Please help me!

The pic below shows the actual wheel. It's a 2009 wheel I think.

I believe the 18 inch wheels have a 60 offset - I have the 17 inch on my 6i GT and those have a 55 offset .
 
The difference in offset is related to the width of the rim. The 17 inch rim will have a different offset due to the narrower width from the 18 inch rim, which is about 1/2 inch wider.

The rims will fit.
 
Ok, great!

I found a wheel offset calculator that I used to calculate the wheels (see below). The rim edge on the suspension side will be about 0,8 inches (20,7 mm) closer to the suspension compared to what it is now with the new wheel. The outer wheel edge is only about 5 mm closer to the fender so that shouldn't be a problem I think. Is there usualy enough space in a wheelhouse/suspension? I don't want the rim to touch the suspension. I understand if you guys with MS6 don't know about the space in my MS5 wheelhouse but perhaps someone know anyway. :-)

Thank you!

You can have a tire that is 1/4 inch away from the rear suspension without it hitting anything. The suspension design of the models are the same, except maybe a sway bar that is stiffer on one than the other.

With the TPMS, as long as you have the sensors in the rim, they will work.
