185/60r15 Tires on Front

Mon Jun 08, 2020 1:13 pm

Has anyway successfully used 185/60r15 tires on the front with no modifications? If so, what has your experience been?

I have 195 45 15 proxes t1r on all 4 corners with helium 6.5 x15 rims 7 lbs lighter per corner than stock I'm doing some test to compare range per kwh with stock rims and tires. But this set up gets rid of plowing and makes the car way more fun at the expense of slightly rougher ride and noisier tires

On the stock rims I have original tires on rear and ecopia 422 plus just installed will update on my findings

And yes I will compensate in my calculations for smaller diameter tires

With the 195 45 15 proxes I get 5.58 mi / kwh on a certain round trip. This is compensating for tire diameter (actual on display was 5.74mi/kwh)

With brand new ecopia 422 up front and stock not new tires in rear I get 6.5mi/kwh on same round trip

All this is with no AC or heat FYI

Supposedly as the ecopia wear my mileage should increase we shall see
