Gentlemen: This covid stay at home stuff has got me tinkering with my ride. But this is new territory for me. Been looking at the tire calculator chart for a mild combination of tires. Two questions for you: (1) will a .5" difference in height make a noticeable rake ? I want very little, if any rake. (2) Is a 1.5" difference in width noticeable to the untrained eye? The car is a 1968 Charger H code & 4sp. All stock. Thanks.
