New truck

[jeepmedic46]

I just bought a 09 chevy silverado crew cab with 275/50/20 tires. Having a hard time finding what the original wheel is. It has the Z71 package.

look on the doorjamb, should be on the sticker there.

Agreed with the door sticker. Also one in the glove box (not sure if it's on the NBS trucks) with RPO codes. Those should tell you EVERYTHING: wheel size, paint color name and code, options, where it was built...etc.

I never thought of that, been looking online for tire size and what comes with the Z71 package with no luck.

Not sure about the trucks, but my daughters 2004 Z71 Tahoe has 265/70x17's on it. My 1993 Z71 extended cab had 265/75x16's from the factory. The truck has been upgraded to 285/75x16 tires. My daughter is installing 285/70x17's on her Tahoe when her current tires wear out.
I run Yokohama Geolanders and Falken Rocky Mountain AT's on my 1993 and 2000 Suburbans. Both are 285/75x16 tires. With rotating tires every 9 to 10 thousand miles I get 50 to 60 thousand miles out of a set of tires.
I am sure you could easily run a 285 tire on your crew cab if it's a 4wd.
I mentioned if it is a 4wd because I think for a few years you could buy a Z71 2wd Chevy truck.
I run all these tires on stock Chevy 7 inch wide factory aluminum wheels.
Any tire store that tells you that 285 tires on stock factory wheels don't meet their guidelines for safety, ask them if they will put a 33/12.50x15 tire on a 8 inch wheel. If they say yes, tell them the tire tread width to wheel width ratio is the same.

Getting the truck today, will be able to see on the door jam what is stock. Would it have been a different size tire on a Z71?

 

[justcuz]

Yes Z71's come with one tire size bigger than other trucks. Stock tires on a 93 truck were 245/75x16, Z71's came with 265/75x16's.

This one has 275/55/20 tires, no skid plates and looks like regular shocks. Is there a place I can check to see if it actually has the Z71 package and not a fake?

Glove box RPO codes. One of them is "Z71"

Here is my RPO code list for example:

As was mentioned, look in the glove box for a sticker with all RPO codes. They will be there in alphabetical order. Make sure it says Z71. Here is a good decoder:

Thank you, I'll check in the morning. What should the Z71 have come with?

 

[jeepmedic46]

No Z71 sticker, looks like I bought a fake

So, no Z71 code in the glove box?

No Z71 code in the glove box. The code that is there is 7jw. Looking online for what that code is with no results.

Here's a master list of RPOs: http://www.longroof.info/pdf/rpo.pdf

Z71s have skid plates (they're pretty basic and kind of cheap anyway), shocks, fender flares, the sticker, and G80 rear auto locker. (G80 RPO code). That's what I remember off hand.

Also here's a place you can enter your RPOs for a list. I keep a PDF saved for reference :ylsmoke:
