trying to figure out what the biggest tire from the DOT slick area i can fit under my stock wheel tub 69 dart
-- Agree with mopowers. -- Here's a 68 Dart, that I built, I believe the spring off-set was 3/4". The wheels were modified Mopar 8" steelies, with a 4" backspace and 275/60-15" BFG Radial T/As.-- If you the simple 1/2" offset of the springs a 275/60/15 will fit. You've got to nail the baskspacing of the rim though. --
I did the spring off set kit and a set of factory 15x8 rally wheels and got 275 60 15s-- Agree with mopowers. -- Here's a 68 Dart, that I built, I believe the spring off-set was 3/4". The wheels were modified Mopar 8" steelies, with a 4" backspace and 275/60-15" BFG Radial T/As.

Stock wheel wells, stock spring location...I fit 255/60R15 on a 7" steelie with 4 1/2" backspacing. It is very tight but it fits
255 is pretty much the max for Dart's with the stock spring location and stock wheel wells, and those won't work for everyone without trimming or rolling the quarter lip back for clearance. Some cars can, some can't and the backspace has to be pretty much perfect. I wouldn't even go quite as far as saying a 245 was a sure bet for everyone, but it's definitely a safer bet with everything in the stock locations.
275's are the max with the 1/2" spring offset, and even those sometimes require some quarter lip trimming/rolling.
BUT will it fit with a 10''-12'' rim like that tire should have???If you do the simple 1/2" offset of the springs a 275/60/15 will fit. You've got to nail the baskspacing of the rim though.

My 255/60's ride on an 8'' rim so 275's should get at least 9-9.5 right...You're kidding, right? A 275/60/15 on a 12" rim??? LOL

According to the tire chart I use a 275 is ideal for an 11'' rim but will squeeze on a 9.5, the wider the rim the better your handling and even tire wear will be. A narrow rim promotes wear in the center only, unless you lower the tire air pressure but that ruins the possibility of good cornering.

Can the rear offset hangers be used without doing anything to the front hangers??
A 9.5" rim is the MAXIMUM width rim for a 275/60/15. Those are straight off the tire manufacturer recommendations.
An 11" rim is not ideal for a 275/60/15, it's not even recommended.
Like I said earlier, if you were talking about a 275/35/18 it would be a different story because of the much shorter sidewall. But even in that case the recommendation is for a 9"-11" wide rim. The rim should be roughly the same width as the tread width, not the section width, unless you're talking about a very low profile tire. Not sure what "chart" you're using, but something isn't right.

So will be the max tire size and rim offset for a 72 demon with stock wheel Wells and stock location of the springs I'm going with 15 in wheels 8 in wide
hello, I have a set of 14x7 cragars and want to do the same thing basically. small tires on front and max out tires on the back. I believe the rims are the standard backspace. sure could use some help here. thank you brianSo? Something on the internet is inaccurate. There's a lot of bad info out there.
It's a generic calculator, and based on all the graphics I would say it's biased to modern, low profile tires, which 275/60/15's are not. My information is coming directly from what's recommended by the tire manufacturers for that size tire. Sure, the calculator might get you in the ballpark, but you still have to check the specs for the tire you're actually installing. I could post a dozen calculators that would all have different numbers. Look at the specs for BFG T/A in that size.

That's a totally different car. What will fit on a '72 Demon with the stock springs is totally different than what will fit on a '69 Dart. Send me a PM and I can get some more info from you so as not to derail this thread.
