I used to run the VW 165 R15 tire on my car along time ago. My observations is that it was too small and coulnt hold the load.
I then went with a 215 -70 R15 on a 15x4 in wheel. It was bulged out some what but looked good & skinny and was about 27.5 in tall. This tire went low 10s regualrly and was the subject of some nasty launches.
If i had to do it again I would run a 205-70 R15 instead.
My buddy found a regular Nitto street radial in a 195-65 15 that looked real good in a 15x3.5 rim
