Time to order wheels and tires.
Dart or Duster style bodies?
Dart. Duster has an extra 1" to the quarters. But it depends on the axle, and how wide you go with the tire. 4.5" of backspace works pretty good on a Duster with a 275/60/15 and an 8 3/4 with BBP axles, with a 215 you'd have a ton of room to the outside.
with all due respect sir, I have been building buying, measuring and doing all my own homework for 35 years. at the moment , I have 4 different sets of wheels and tires for my charger. I use a tape measure and a little math to figure everything out. guess what ? I have never bought a wrong set of wheels and tires that didn't fit or that I had to return. you can sit here and guess every measurement , but you know as well as I do , every vehicle has it's individual tolerances and variables. the only way to truly know is to measure the SPECIFIC vehicle you are working on. which means getting the thing put together with the suspension loaded up and get to measuring. I had someone trying to say a 275/60/15 on a 15x10 wouldn't work on a stock 73 duster with a 7 1/4 rear !! I ran that **** for years without one rub in front . he showed pics of his touching the front of the wheel well!! this is why you can't just read **** on the internet , you have to measure your own car.
have a good day sir.
one more thing , if Mr. gtx internet stalker would stop alerting me because of his retarded quoting , I would have passed on this thread yesterday.
Right, except 35 years ago you couldn't get 17" rims, or 18" rims that will clear the outer tie rod ends with over 6" of backspace so you can run 275's on the front. You couldn't get 13" rotors and 6 piston calipers that had different clearance requirements for the rims. You couldn't even get tires in more than a few different sizes that would actually fit, now you can choose from dozens of different height/width combinations if you run 17" or larger rims. So really, anything past about 10 years ago doesn't mean much at all.
Figuring out the backspacing for the rear axle is a piece of cake. For one car? I could have 8 different sets of rims for my Duster if I wanted, I only have to measure it once so who cares? Once you figure out the absolute biggest combination that will fit anything else is just extra.
And, I'm
not guessing. Yes, the body tolerances on these cars do vary a bit, but it's usually by a 1/4" or less.
Usually. And if someone is trying to fit a tire that will absolutely max out their wheel well, I tell them to measure their car. Because if it comes down to a 1/4" making or breaking the fit the body tolerance will make or break it. But if you could see my inbox, you'd see that it's filled with dozens of messages regarding tire and rim sizing, just covering the last few months. And measurements from dozens of different cars. Different years, different body styles, different axle and brake combinations. And I keep a spreadsheet of all of them, so I have a pretty darn good idea of the kinds of tolerances that the factory had.
Yes, I've been wrong. There are always exceptions, and I'm only human. And I DO tell people to measure, quite frequently in fact. And when I do, I actually tell them
how, not just that they need to get a tape measure and stop asking people on the internet, which helps absolutely no one.
And, not everyone is good at math. Or spacial visualization. Or figuring out the difference between offset and backspace etc. So breaking out a tape measure doesn't help everyone.
