Texas states must have a light transmittance value of 25%. Does that level provide enough? I’ve always had cars that already had tint. The tint on my Honda seemed pretty dark and it was new from Honda when I purchased it. I think it’s darker than 25%
Great question! The darkness of the tint actually has nothing to do with heat rejection (it’s a glare/cosmetic issue). You can get almost clear 70% tints that offer far superior heat rejection versus stock. In my experience the stock tesla windows let a TON of heat in. In order to protect your interior ... and increase range due to lower HCAC use...a tint is one of the best investments you can make. A trusted local tint shop will help you find the right product. Modern tints are insanely effective, even if they aren’t dark at all.
