Appropriate Wheel Offset for 18" Wheels?
I visited my friend today and borrowed his Mustang wheels with 275/40/17's on them (he's got a late 90's or early 00's GT). He also gave me a 245/45/17 in case I wanted to swap them. The 275/40/17 is a Hancook Ventus and the 245/45/17 is a Nitto NT555. The jack stands are mounted underneath the rear end of the car with an 1/8 tank of gas (so the suspension is loaded). So, I tried the wheels on the driver's back of the Dart, no spacers or washers, it seems like the tires will fit with little modifications just with less offset. The wheel is flush on the rotor surface. and I can spin it freely without any rub.
In one picture, there's about an inch or so till you hit the outer wheel lip and if needed I could even trim that down a touch. In the other, there's a touch of room (maybe 1/4") between the leaf spring and the tire. Sorry for the funky/blurry pictures.
So, am I missing something? Is the suspension not loaded enough? How much room should I look for between the tire and the outer trim/leaf springs should I look for? With a little trimming and a different offset, it seems like a 275/35/18 should fit without much of a problem.
