Before I decided on my tint, the counter guy at the shop was showing me some examples. Pointing to a BMW with 20%, he said, "That's our most popular tint right there, but it's not legal." He also mentioned that applying 35% tint to most cars will actually result in something darker, which would technically not be legal either, since most OEM glass already includes a slight tint, and the effect is additive. Made sense to me.
Depends on the factory tint. I believe most of them are around 10% and you can add another 25% to stay legal in most states. In IL its 35% tint all around (no windshield) or darker behind the B-pillar with no additional tint on the front doors IIRC.
When they did mine the measured carefully and depending on conditions my total tint is about 3 % more (or less) than the limit which is OK with LE since there is measurement error they need to account for. At least that's what I was told
Problem while talking about tiny is that people talk about two different measurements. Either how much light can still pass through or how much is blocked. Makes it sometimes hard to wrap your mind around.
