Here's another one with 295/50 R15 on 8" in the rear (fronts are 235/60 R15 on 8" as well):

I had some 325-50-15s stuff on a 15X8.5" rim on my 69 Barracuda also. The tires were way to wide for the rim though and Im not sure you could even get a set of radials on them LOL

295s on 8s

The taller aspect ratio tires do not appear as bulged on an 8" rim as do the shorter sidewall tires. Taller being 60 series and more and shorter being 50 series and less. This is because the additional sidewall provides more area for the arc to be spread over. In the drag racing world, this is actually a benefit in absorbing the initial hit and the BFG 295/65 drag tires look right at home on an 8" rim. With a 295/50 series, it does create enough sidewall bulge that you may need to run them down around 28 psi to get a full contact pattern out of the tread.

15x8 with 295's on the rear of my Charger.

8" rims? Seriously? They are way too small. It might "look" OK cosmetically but you are leaving a lot of performance on the table going that route. I ran 255/60R15's on 7" rims and if I didn't lower the tire pressure substantially the center of the tread wore out first. Which ought to tell you that in this case the entire tread width was NOT contributing. So I lowered the pressure enough that I had an even contact patch and ended up right on the edge of too little air pressure causing excessive sidewall flex making the rear wiggly.

Can you run those meats on an 8" rim? Yes, but if you are going to pay for the meats you may as well be able to use them completely by running the right width rim and 8" ain't it. It's more like 11", but 10's can work if you drop the tire pressure a bit.

SuperCuda... Yeh.. I know... 295-50s on 8" rims may look cool around, but they will buldge alot... and they'd certainly benefit from 8.5-9-10" rims best (10" or 11"). So, more than likely I'm going to NOT get the 295-50s... probably 255-60-15 front and repeat the 275-60-15 BFG T/As.... just for street/hwy driving on my 15x8 vintage mini-lite rims. I have 16x10 road race rims for serious competition (275-45-16 Hoosier A6 race radials).

8" is definitely too narrow, and i dont even think they look good... the bulge aspect i mean... the width still makes up for it. But 8's are all you'll get in some rims, or on some cars. To use a factory rim you're stuck with 8", and to me at least, a 255 is still a Honda tire. I dont care how wicked-fast some cars have gone on narrow tires... i just personally have to see some meat on my cars. The 265/50's on the front ov my 70 just look... well, small.

9" minimum for the tire performance/wear i think with a 295/50, 9.5" is probably perfect. 10" looks good as well, but even 10.5" starts to go the wrong way in my opinion.

My Challenger's getting 15x8"s... for now. When i can afford some nice 18" that dont weigh 30lbs a piece i'll get the ratios just right...

Pale roader -- your previous picture of the Chally with the 295-50s all around looked awesome, though the backspacing may have pushed them out a little too far... were those rims 15x8 SuperCoupe rims? or what? (the 8" Super Coupe rims have, I'm pretty sure, a 4.0" BS.. and it should properly become an 4.5" BS to fit properly with the retained centerline as a stock 7" rim. The "buldge" of these tires on the 8" rims is, I agree, too much. Those BFG tires are low-cost, as are most 15" rims, so, there's the comprimise.

Considering my ride height is lowered, and size rims/tires, etc, and the SCCA class rules for "Street Prepared" (my class is E/SP) allows fender mods, etc, my lips are mildly flaired ... but done in a great stock-appearing way (my best friend/mopar buddy owns a body shop)... fronts are flushed/pulled a liitle and the top brace removed/not needed anyway; the rear were more difficult... lips cut/pulled but kept like stock appearance, lips re-welded and inner areas of fenders re-welded flush, etc... looks great and still apprears factory stock unless you'd really study them with another Chall next to it... all this done to accomodate 16x10 rims with originally 255-50-16 Hoosiers, later 275-45-16 Hoosiers.. you can barely fit your pinky fingers between tires and fenders... no rubbing even during racing! Then, with my 15x8 mini-lite rioms and 245-60 f, 275-60 r BFG T/A tires, there's plenty of space within the fenders.

Better shot of the wheels & tires. I have had these on there like this for over 12 years with no issues. I don't drive this car in road courses or anything so it is just fine on the street & gets many compliments on the looks.

Here 295 BFG t/a on 15 by 8 rim.

how bout 325/50's on a 10" rim dr diff relocators and a b body rear needed a 1/4 spacer on the pass side. espo drop springs in the top hole.

Thanks for that info. Do you know if the Cuda has more or less room than the Challey? Also what back space on the wheels? What kind of clearance on the inboard side? Your lips do not appear to be rolled either. Is this true? Spring relocation kit with the 1" or the 1.5" offset? Sorry for all the questions. Thanks!

the rims have 5.5" back spacing i never have people ride in the back seat bumps haven't been a problem the fender lips have been rolled as well. i really haven't drove it much since i put the combo together i have to pull the leaking crappy 440 source water pump housing off before i can drive it again.

its a mickey thompson et street radial. if your turning corners i'm sure you want less sidewall to deflect. i have had 295 50's on the back of it before on a 8" rim with the stock rearend.
