Dude just go with 205s on a 7" and make sure they’re GOOD tires. It’ll make the world of a difference. For example, compare 205/55/16 Potenza RE01s to 215/55/16 Toyo Proxes TPTs; i ran both those tires last year.
That 10 mm difference wont mean shit. The RE01s are a much grippier tire and you’ll notice it.
