When I restored my 72 Skylark, I put 15in. Cragars on it with 215/70r15's on them. My question is how will this effect the speedometer accuracy? Car came with 205/70r14's. Don't want to get a speeding ticket thinking i'm going 55 or 60, and be going 65 or 70. Can anyone help me here? David Riggs
Right When you take the step up to bigger rims your speedometer will say 65 but you will be doing around 60. Maybe not even that much 1" don't make to much of a differents. Ziggy 350 Regal Build
