You just answered my next question.
I thought about a 16” rim for the front and a 17” rim for the rear with American Torque Thrust and GoodYear Eagle Sport.
Whatcha think???
I'm not a rubber band tire guy...If you're putting them on the 69 B I would use a rear tire that will fill up the wheel well. I had to push the limit with the wheel selection to fit the advertised wheel width for the tires I chose. I tried to mount mine on a friends 68 coronet...due to difference in the wheel well openings they would not even slide in and engage the studs. A Road Runner...GTX and Satellite have larger wheel openings...at least in 1970 they do.
I pushed the limits to get the height...width and stance I wanted. My rear was moved back 3/4" and I also run 1 1/2" lowering blocks on the Super Stock Springs to lower it down some.
In the end what you like is all that matters... .02
I kind of did the same thing with my 65 Belvedere II Project that has fallen completely off the rails...
I chose a rear wheel and tire that I wanted and built everything else around those...
I had found a 17x11 with 7 1/2" backspace TT-2 wheel very similar to what you posted.
It looks like a stock 8" wheel from the side but has a chit-ton of back space.
Thought if I could ever find a tire for these that was tall I'd get them...Stumbled across Hoosier 31.50x16.50 17's and bought the rear tires and the rear wheels. (Big Mistake in a way)
The openings in these wheels in 17's are so large you can see everything behind them...The little 10" drum brakes and the 8 3/4 rear looked out of place...
I upgraded to a Dana 60 and 13" Wilwood vented-slotted-drilled rear rotors and Polished Calipers. The rotors have the parking brake shoes inside the rotor hub so since I was going with a stick I would still have a parking brake.
The tires were too wide to retain the inner or outer wheelhouses so everything got cut out and new 2x3 frame rails and a 3 link with coil-overs went back in.
Ultimately the point I want to make is don't get too carried away as it will cost a small fortune...
