GMC Yukon / Yukon Denali



  • fellersfellers Posts: 18
    Safe 1 or others,

    Any resolution from the dealer on this issue? I have a 2001 Yukon XL Denali and while the 4 corners have the 17" Michelin, the Spare is the 16" Firestone. Seems like a joke and will cost me money when I replace the tires as I usually take the Spare and only buy 3 tires. Not to mention if I have a flat, the inconvenienc of one tire at 16" and the others at 17".

    Did I infer correctly that you have more than one skid plate on your Denali? If so, where did you get them and where do you have them installed? Are their mounting holes in place? I have always had skid plates on my SUV's but it was not offered on the Denali? Thanks.

    Ok, too many of you guys don't know how to calculate tire height... So here is the lesson (again).

    2x(sidewall height) + rim diameter = tire diameter

    Michelin P265/70R17
    2(26.5cm x 0.70) + 17in x 2.54cm/in = 80.28cm

    Firestone P265/75R16
    2(26.5cm x 0.75) + 16in x 2.54cm/in = 80.39cm

    Therefore the spare is 0.11cm (0.0433in)taller than your Denali Wheel and Michelin tire!

    Ok, you are out the price of 1 tire to rotate into the others. Hey how did you afford the vehicle in the first place. Long story short, it will be hard to convince the dealer that the spare is the "wrong" size.

    My Denali came with a skid plate which covered the front half of the transmission and oil pan, I added the second skid plate to cover the back of the tranmission. I have some fairly treachous rocky inclines to get thur on my cattle ranch and didn"t want to lose the casing on rocks. My dealer ordered and installed the plate around $125 total. The AWD performs great offroad. I don't think the firestone spare is that big of a deal, but I would have been happyer with tires that matched. I do some pretty heavy towing, can anyone tell me if you can damage the vehical under a heavy load if you have to use the spare? An eariler posting calculated the rotation differences and It didn't appear to agree with Daves figures, but I'm no engineer.

    I'm still awaiting a build date for my Denali so I'll wait and see if the spare is indeed a Firestone. However, in a recently discussion with my dealer rep on this topic, he did indicate that "something" could be worked out if so equipped. Sounds promising but.... Will post when the truck is delivered.

    No, I didn't pop off the radiator cover, nor did I use rubber bushings. The emblem comes with four double ended screws, four metal wahsers,and four locking nuts. If you look closely at the emblem housing you'll notice that there is a black plastic casing (the casing is mounted on the grill, the emblem is mounted on the casing). When I received the emblem in the mail I didn't think it would fit, but it did. It took about 10 minutes to install. Good luck!

    Be careful with a 2001 Denali if you are taking four friends and towing. The Denali only has a 933 pound payload. This explains why it can't have a front bench seat or a third seat. Plus, it can't tow a medium motor boat and seat five full size adults without overloading the vehicle. Wait for the 2002 Denali. If it is like the Cadillac Escalade, it will be improved up to a more reasonable 1450 pound payload. For comparison purposes, a 4WD Yukon SLT would have a better 1680 pound payload.

    Not sure where lambdapro is getting his info but the GMC site has the 2001 Denali and Denali XL with a 1510lb payload.
  • lambdaprolambdapro Posts: 51
    Here is the link that I used for the information.
    But I agree with heatwave3 that this site must have bad information. It must have been for an older model. The current ratings are as heatwave3 states.

    Does anybody know if the "Wood Trim" on the Denali is plastic or real wood. My salesman told me it was wood, I have my doubts. I don't think he would lie about that, but i do believe he was misinformed.
    Also, sunroofs, ASC vs Webasto Hollandia, any of you know about these roofs and quality of each.

    The wood trim is definetly not wood its plastic. I removed the large dashboard piece to install a relay and it is molded to the metallic like silver dashboard. Sorry to give you the bad news.
  • mbclk430mbclk430 Posts: 58
    It's plastic, buddy.

    I talked to the dealer about the 16" spare issue on the Denali and it took him by surprise, apparently. He called the GMC Technical Hotline and they told him that it is "intended to be 16" and for temporary use only." Obviously, this GM response is a bunch of bunk but that is what GM is saying. I don't like it but what are you gonna do? Anyone have any other success in getting it replaced?

  • I took delivery of a 2001 Denali with all four tires at 42psi. I talked with Michelin and they told me to use the psi stated on the door, which is 30psi for all four. The tires "look" very low when I do this. What are the rest of you using?
  • don4341don4341 Posts: 69
    Sorry I thought it was still $6.00.
  • larry91larry91 Posts: 189
    Thanks, Plastic, just as I thought. I will have to inform my salesman tomorrow of his error..
    U would think for what we spent on these vehicles, it should be WOOD, ah well, such is life

    I'm running 31psi rear and 34psi front.

    larry91: A little late in my response but I own a 2001 Denali XL. The trim is absolutely, undeniable plastic. In fact, its really just a continuation of the rest of the plastic dash trim. Not awful, but it should have been real wood and I will be adding a wood trim kit.

    I also installed the ASC sunroof aftermarket through the dealer. The same sunrof as factory with much better controller. You get to have rear climate control and one touch close and auto-close on the sunroof once the engine is off, neither feature is available from factory. You won't be disappointed as the auto-close feature can't be beat.
  • Thank you for your response. What is the benefit of running higher in the front?
