2003 Mazda Protege5
I recently bought 17" Mazda 3 rims and was wondering what would be the best tire size to put on so they don't rub and they fit properly (btw it's not lowered, stock height) I was considering either 215/40 or 205/45. I live in Montreal so as anybody who lives here knows, the streets are horrible, pot holes everywhere.

I'm open to any tire size, not necessarily a size I listed above.

Thank you
 
If they're the same thickness, then go for 215/40/17s. Closest overall diameter to stock, difference is 0.43% versus 2.44% with the 205's.
 
but dont I run the risk of damaging the wheels with 40 series tires? and am I going to notice a difference in comfort between the two sizes?
 
I'm running 17/215/45 Contis on 17/7/+40 rims. Civilized ride, no rubbing on stock fenders, MSP springs, Tokico Blues.
The lower the sidewall aspect ratio, i.e., 40/45/50/55 (sidewall height), the rougher the ride, particularly with coil-overs.

You'll notice that 215/45/17s are almost a perfect speed match with OEM.

You put 215/45/16 into that calculator. The closest match is 205/40/17.

Yeah, you could damage the wheel. Just do your best do avoid hitting huge pot holes at 50mph and don't run up any curbs, you'll be ok. Drive carefully, basically.
