Well, I did it, since they were only $3.86 each, I tried it.

I put 20" wipers vs the listed 18" windshield wipers on my Tahoe...

I had been meaning to try it; since I watched where they hit (its pretty obvious if the truck's dirty) and it looked like there was more room...

So, I put them on, and no ill effects; just more of my screen to see out of!

I also went from a 14" rear to 15" with no ill effects... I think a 16" would work in the back too...

So, if you have a 1995-whatever (99?) Tahoe, get some 20" wipers

just FYI...

I figure if I can spend $10 to improve my 1995 tahoe; that saves me $590 over a new one lol
