Wheels choice
Hello all,
I am about to change my wheels.
I have two options :
Stick with the 195 65 R15 wheels where I intend to have the least RR tire available (namely Bridgestone Ecopia EP001s) on the rear only (the front have some thread left)
Retrofit the 205 50 R17 wheels I had previously but with 205 55 R17 for a significant (?) 4.8% increase in perimeter.
My mileage is 25% highway (from 70 to 83 mph), 37.5% errands (around 50mph) 37.5% city but it is about to change towards much less city.
Regarding potential in FE increase, I am not after a short term return on investment, I consider the chase for the MPG number and least impact on environement rewarding already (within reason !)
So, what is your opinion ?
Alternatively, what difference in RR should I put in the calculator to evaluate the impact ?
