tires and rear window

[BUEFORD]

I have a stock 87 k5 and was wondering if anybody knew how big of a tire I can go to before needing to make modifications to the truck. Also my rear window works from the console, but not from the key outside. Does anybody know what might be wrong and how to fix it? Thanks /forums/images/graemlins/k5.gif

For the tire question: read this.

For the window question: /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif I guess I'm not too sure what you're asking? The power window switch operates the window...but the key doesn't????? Is it supposed to???? (Sorry...don't own a K5)
