Tint UV on rear windows?SR5, double cab

Are the factory stock rear windows, non_UV ? (2020,double cab).
Gotta re-tint everything?

 

It’s just smoked glass. Not tinted, not UV resistant.

 

I tinted the front windows only. Paid $80 for Llumar ATC 30 film. It's a little lighter than the rear privacy glass.
If you live in a hot climate, Arizona, Texas, etc and you leave your car outside in the sun, you may want to tint all around.

 

I tinted my back 3 (over the privacy glass from the factory) with 35% Llumar and the front 2 with 20%.

 

i did the same to mine....cant recall tint level....

 

I did 20% front doors, 50% rear doors and back window (over privacy glass). All the windows light transmission were within 2% of each other when tested.

 

I did 30% all around, back is super dark now. Perfect for me.
