What you have done is totally opposite, if you want to keep different pressure front and rear for a car that says same for all tyres always keep front more because of following reasons
1. The front tyres in a front wheel drive car take more friction and forces so needs more pressure
2. The engine weight is at the front while mostly if you donāt have passengers in the rear there is no weight at rear
3. The front tread will always wear more than rear tyres in fwd car and by lowering the pressure in front more than rear you are rather accelerating that tyre wear more
4. Due to weight in the front as mentioned above you can visually also see that the side wall of tyres at front is smaller to look at compared to rear tyres even when tyre pressure is same
This is a front wheel drive Honda Civic and not a Bedford truck which has a load of stones at the back requiring to keep more pressure at the rear. What you have done is totally opposite for the car
Keep front more than rear if at all you want to do it and you use the car alone without rear passengers mostly
