I'm looking for the "translate to english" button.
I'm not sure where those numbers are coming from, and what they all represent.
I asked about 7 inch rims, and you're starting the equation with 6.5?
Where is the 25.4 coming from? That sounds like the overall tire diameter?
Are you saying that on a 7 inch wide rim that 4.82 would be the maximum backspacing?
The guy at Corsa Wheels is suggesting a backspacing of 5.0 on a 15 x 7 - which is a 25ET
Given that the Bertone wheels are 15 x 7 with 20ET that extra 5mm should bring the wheels in more, and maybe reduce that rubbing under compression that that you mentioned, Ken?
What size tire you running?
Are you using adaptors to fit them?
205/50r16 on those wheels. No adapters, I had them redrilled to 108. I also have a set of 15x7 with 5.25 backspacing, and I am running 225/50 on those with no rubbing. But, like Ken said, my rear axle is in a different spot than yours.
That's the size tire I'd like to run on the 15's
Any chance I could try bolting those 15 x 7s on my car and see if they fit?
I'm more visual, than mathematical...
Definitely. They're brand new Corsa Steelies I had custom made, and they have essentially new Toyo Proxes r888r. I bought them with the intent on autocrossing the car a bit, but I doubt that'll happen now that other life stuff has come up. I'd happily sell them, but I'm sure you don't want r compound tires to drive around on the street...
Buy the stock RWD 15x5.5" Volvo steel rims then have a 1.5" band added on the outside. Worked perfectly on my 145, 245, 744T, 964, 965. The set I had made (by a stock car wheel builder) now wears 225/50 R15 race rubber.
