I picked up some new and cheap rear tires for drifting fun for the E30. I go through tires alot so keeping it cheap and fun is perfect for what the E30 does. I went with 195/55/15 to go on the 15×10 so it would match the stretch that the 185/55/15 has on the front 15×9 wheels. The tires come in at about 10-20 bucks cheaper a tire than the 205/55/15 I ran previous. I will be spacing the rear wheels out another 10mm to even things out also.
