Widest rear wheel for a 69 coupe?

I'm going to be running a 408w (if i can find a good shop) with afr 205 heads and a custom cam for max power so I need lots of grip in the back.
What size do you guys recommend for the wheels and tires?
I just want the largest I can stuff with fender rolling.
I was thinking about torqe thrust wheels but I'm not set on those yet.
I have a set of cobra brakes for the front so I'll need 17" for the front IIRC

I've got the Dodgestang chart you can take a look at......... it's beer 30 here
and I'm not really willing to interpret his notes but if you send me a PM with
your email, I'll send you his chart.

As the drill sergeant said, "I taught you everything you know. I didn't teach you everything I know."

Did you have to mod anything to fit them?
The chart shows 15x8 with 295 x 50 fit fine

I have to go with 17" fronts since I have a set of cobra 13" brakes. I think I remember seeing explorer disk brakes work on my 9" rear but I don't remember seeing a minimum rim size. 17" 225 tires up front and 15" 295's in the rear sounds tempting

hAS MORE TO DO WITH THE PROPER OFFSET so my wheels are semi custom.

Weld wheels was one company that would do it for a decent price. Have heard rumors they have been bought up and to be discontinued.

I began running 295 50 BFGs soon after they came out and found they worked out best on 10" rims. Their dropping of 275 50s which I used did run on 8" rims really upset me.

I liked these a lot because of their load ratings. Could go off on the evolution of there tires also as they changed tread designs over the years also.

I've got 295/50/15's under my '67 by dint of some wackyness which I wouldn't recommend and am going to redo anyway. I find Cooper Cobras fit just a bit better than BFG's for me. The profiles are a smidge different.
But Turbo, do you know what offset you ended up with? I like 295's and wouldn't mind putting some under my '69 but it will be all stock in the rear except for the rims.

Sorry cant remember I switched to a old Franklin quick change back in 83 84 in my 70 coupe. The 69 that had the 9" was totaled by a guy that ran a red light. The QC is wider and had to do a major inset. I might be able to get a side wall dim to the inner wheel well. Then you could do some measurements to figure back spacing.

I just purchased some Hankook 295 50 15s for my 87 country squire and 265 50s for the front I LIKE BETTER THAN THE COOPERS which I DISLIKED IN THE WET. The Hankooks are only a few tenths different in side wall and tread widths on the 295s BFGs and 265s are almost the same dims as the 275 50 BFGs .

I can figure it out the hard way if need be, wheel fitment is actually WAY down my '69's to-do list.
At one a time I got a friend at a tire shop to hook me up with bald 295/50's. Goodyear, BFG, and Coopers. Which I used for trial fitting. I didn't know Hankook had any, I appreciate the heads up. The best thing I can say about Coopers is that they have a snake head on the sidewall.

On my 70, I also have 10" wide x 15" with 5.5" BS wheels on my 70 with no issues and plenty of clearance. I am running a drag tire, 28"x10.5x 15", that has a 12.3" section width.

Excellent info! Thanks.
If anyone asked me what sections width and offset I am running it's fair to say I haven't a clue. I might try to write that stuff down next time. I observed different section widths on those tires I test fitted but never thought to measure them. Next time.
