    How's the handling when the derivation from front to rear is over 50mm? Like 255/315.

    I'm looking for options, I've got 19x8.5 / 19x11 wheels on the way and haven't decided on tires.

    I'm looking at 255/305, but was concerned with the handling.

    Any feedback is appreciated.

    I have spent a lot of time on this as well. Mine is a 78. I have not purchased yet but have come to the conclusion after a lot of measuring that the biggest I can fit without modifications is a 275 with 5.5” backspace on an 18x9.5” wheel. At that size I should be about 3/8 or less away from the rear spring. It looks like I might need to pound the seat belt to get the tires to fit. I also have about a 1.5” drop in the rear.

    Short story, I wouldn’t go wider than 275, but lots of people have different experiences as you can see.

    I'm currently running a 275/40/18 in the rear with hotchkis leafs. And I have about an inch or so of clearance all around the inside.

    The wheels are 18x9.5 Vette wagon wheels (all rears) +65mm, with a 2" adaptor.(equivalent to 5.84" BS)
