Weird tire clearance

[luckyforrest]

Hi, I have owned the Mirage G4 for almost 4 months, but just noticed that the clearance of the two rear tires are significantly different: the clearance of the driver side is merely 5 cm, while the other side is 7 cm. The clearance of two front wheel is 7 cm. If I recall correctly, I did not notice this difference when I bought the vehicle.
Tire pressure checked, all four tires are 3.85-39 psi. Had the alignment done four days ago at the dealer (the car pulls to the right due to alignment issue) after the alignment, the car is doing better, but seems pully slightly to the left, just a tiny bit. I replace the original tire with four 165 65 R14 winter tires last night and found the clearance issue, but generally, the car drives great. I also checked my wife's car, the clearance of all four wheels are pretty consistent. Should I worry about the variance in clearance? Thank you!
