My 70 charger has 18x10 FR500s currently. I had to add a 10mm spacer in the rear. They are temporary until can decide which wheels to go with. The tires are Nitto 555s. 275/40 front and 295/45s rear. I do have some very slight rubbing at the inside of the front tires. But, I am running a Borgeson steering box and I'm sure that's part of the rubbing. I just finished installing the suspension, brakes and running gear, but so far so good and I've pushed the car pretty hard since breaking in the engine.
