bd90, i did alot of searching online and asked around when i had the same question for my 99.. the bottom line is that no one was able to give me a firm answer on the biggest tire i could fit..

my best advice to you is to keep your eyes open for other trucks the same year as yours and see what size tires they have...

secondly, if you want to run some numbers on some tires..look at this thread to see how you can calculate a tires diameter based on its size
http://gmcowners.com/gmc-forum/showthread.php?t=10591

compare the diameter to the tire you have on now and see how much space its going to leave between the tire and your wheel well...use some common sense, talk to some tire shops, ask a gmc dealer near you, then decide for yourself.. the good thing is that if you buy from a place where you intend on mounting them, they will tell you if they are not fitting correctly or not..i ordered online, so i had to figure it out myself..

Hello, hive! I have a 1999 GMC K1500 Suburban. When I step on the brake pedal, no keys in switch, the dash and marker lights come on. When headlights are off, driving normally, both turn signals work normally, but the dash and marker lights flash with right turn signal. When headlights are on, left signaL works normally, but right signal buzzes a little at the relay, but does not blink, even though the rear lamp does light on the right side. I am at a loss. So is my mechanic. Help??

How did all that work out?
I'm wondering about your preferred PSI for tires.
My mechanic recommended 32 psi for my heavily-loaded 1990 Vandura.
That's what I've used for years (once it was around 36-38, and that felt like I was on rollerblades and could not sense the road . . . ), yet I see videos saying that 32 is way too low and damages tires . . .

(I got 11-12 years out of my tires at 32 psi.)

Thank you for any helpful feedback!

I'm replacing a lower seat foam and leather. The lower foam is attached to a smaller metal frame and is then bolted to the main seat frame. At the rear of the foam/smaller frame there are 2 locating pins that must fit into holes at the rear of the lower seat before the 2 front screws line up with the holes to put screws in. I' not sure what to call them but I need at least 1, 2 would be better, help please.

"I've come across quite a few articles about lifter damage lately. I assume much of it is marketing hype, but I suspect there’s some truth to it in certain cases. Any thoughts or real-world experiences?"
