new member w/ quick question

[rxm6]

Hey everybody,

I have a 75 k5 and a quick question.

Just curious if I can put on 33x13.50 with stock suspension setup without rubbing or without trimming the fenders.

I've definitely found pictures of k5's with 33's on them, but they are raised a few inches. I did find an image of a 76 with stock suspension with 33's on them, but I can't tell if the fenders have been trimmed or not. That was Tink's truck on this website. I also found useRc10's truck with 33's, but I don't know if the 85 fender openings were different or if the tires on his truck are as wide (if that even makes a difference) His truck is also raised 2''

so any help is appreciated, thanks.
