420A Tire Fitment For Stock Wheels

[BLACK'98DSM]

I'm wondering what the skinniest tire I can fit on the stock 14's is. I just want something skinny to put on the rear of the car for race days. I know they had 195's from the factory, maybe I can put 175's on them? I haven't measured the wheel without a tire so I'm not sure how wide they are.

OEM stock rim are 14 x 5.5JJ so 1:1 aspect ration for the tire is P140 before going into sidewall stretch.
