215 or 225 tire selection for 307 vehicles

Hello friends, I am thinking of wearing a tire with 17 inch wheels on my 307 vehicle. I could not decide whether to wear it.

I use 5 and they are 225 back 215. I do not have a kite, but when I get 2 people, I think there will be a problem in the back. This is just my idea.

the original size of my vehicle was 205/50 17 225/50 17, I got the original size again.

Original sizes of Peugeot 307. If you do not go out of these dimensions, it will not affect your fuel or rubbing. For those who use 15 "wheels; for those who use 195/65/1516" wheels; for 205/55/16 17 "wheels; 205/50/17 215/45/17 225 / For those who use 45/17 18 "wheels, there is no fuel difference for those who use 225/40/18 original wheels, but different rims may vary depending on the weight of the rim, engine difficulty, etc. metin2012-05-12 20:05:47

There is a difference of 2% in fuel, but at 225 * 45, but the road grip is excellent, but performance is noticeable at 1.4.

I am afraid of the backs, as I swear it, if they surt, they are surter fuel and I don't have a pull out of the car.
