Identifying my Current 15 Inch Wheels - and thoughts about wheel replacements

If you stay with aftermarket wheels, the Torq Thrust type rims look great and you can get them in 14 or 15 with proper backspacing View attachment 1716250419
Hey Topless,
What are the specs on your Torque Thrusts?
Backspacing??? Offset???

I did a lot of research on the web, reading, and measuring yesterday.
I sat down and drew several pictures to illustrate what I have and what I want.
By my calculations, because of the springs n the inside only have 2 inches of clearance with the 10 inch tires that are bulging out of the wheel well......
I belive that I can only use a 9 inch tire (7 inch wheel); and need around 4 inches of offset; -6mm of backspacing.
