    2017 GMC Sierra Denali 3500HD SRW
  1. Winter Tire Setups

    If you want a no compromise snow performance tire - go dedicated winter, not all season. All respect to the KO2's and Duratrac's of the world, but they are all a compromise. I currently run a LT275/65R20 General Grabber Arctic LT in the winter and Michelin Defender LTX in the spring/summer/fall. Pleased with the performance. If I was buying another set today for my 3500HD, I'd be ordering a set of the new Bridgestone Blizzak LT's. Check them out! Can't emphasize enough the difference a true winter tire makes...
  2. Southwest Michigan - around the Kalamazoo area.
  3. Thanks! We are loving summertime here in Michigan. We have a house full of Mastercraft fans.
  4. Sierra Denali HD

  5. Almost 23,000 relatively trouble-free miles. Have experienced the following problems: Low coolant warning message - Leaking lower tube and three service trips to get "air bubble" out of the system Emmission code - required replacement of DEF tank (sensor problem in tank) Minor surging and slow speed drivability issues - resolved by ECM flash in November/December Love the power levels and lower noise from the L5P versus my previous LML's. Overall positive experience with this truck. Only two things I don't like: Regens - very noticeable (higher idle) and always a burning chemical smell if I come to a stop - drive thru's are the worst if you have a regen underway - have not raised issue to dealer Lack of some more modern features (heads-up display, push button start, active cruise, etc.) which should be resolved in next generation model Overall, I would buy this truck again.
  6. I have the same tire in LT275/65R20's and they are significantly better than any all terrain tire that I've run in the past (BFG KO2's, Wrangler AT Adventurer, Michelin AT/2's). With Blizzak made the DM-V2's in an LT rated tire - best dedicated snow I've ever used. First set of this brand for me. Great traction, significantly noisy for me - spring/summer/fall tires are LTX Defenders for comparison.
  7. 3500 vs 2500?

    Went from a 15 and a 16 2500HD Denali to a 17 3500HD Denali. Both Duramax/Allison. No TPMS is great as I like to run the tires at a lower pressure while unloaded for ride comfort. I found little difference between the two on the ride comfort side. Switched from the 18 inch wheels (only size available on 3500HD SRW) to a factory 20 inch wheel and went LT275/65R20 to get the higher-than-factory-18-inch load capacity. Overall, I really no longer see a reason to get the 2500HD. To me, 3500 price point is essentially the same (no tax or registration differences in Michigan) plus I get much more payload capacity with the overload springs and frame stops. Once we hook up our boat, considering pin weight, passengers, and all the gear we throw in the back for a week excursion - have to believe I'm beyond rated limit for 2500HD. Just my .02.
  8. Go to www.kbb.com and build your truck exactly as you either like or the one on the lot is equipped. Take a look at the MSRP and the Invoice. I generally like to purchase somewhere a little less than invoice. Dealer still gets a profit, I feel it's a fair price point for negotiations. Supplier discount is generally a little less than invoice but varies by vehicle. Only spot I can't make this work is if a vehicle is in high demand (brand new model with limited availability or something similar). So, on a 72k MSRP, I'd guess invoice to be around 66-67k. So, I'd probably shoot for 65ish...
  9. 17 3500 Denali Single Rear Wheel. Swapped out to 20" wheels w/275/65's.
  10. Also maybe this is an odd question but I disagreed with my dealer but ultimately went through with the deal, but I noticed the tires are different between the 2500 and the 3500, on the 2500 they are more aggressive Wangler tires, on the 3500 they are more of a highway all-terrain tire. Very disappointed as I wanted that look of the Wangler to match the look of the truck, I have similar tires on my Denali and the road noise was minimal. Am I overthinking this or should I just deal with it or buy the more aggressive tires Not 100% certain, but I believe the Duratrac's that come on the 2500 do not have enough of a load rating in the factory offered sizes to meet 3500 cargo specs.
  11. Just heard a rumor last week that GM is no longer offering the Midnight Edition in the 3500's. You may have a little bit of a unicorn on your hands...
  12. Ran LT275/65R20 BFG KO2's on Factory Denali 20" wheels on my 2015.5 2500. Didn't touch a thing - no rubbing. Just purchased 2017 3500 Denali HD Duramax. Only come with 18" wheel from factory - moved to same 20" wheels as 2500 with same 275/65 but Michelin LTX Defender M/S. Same result. No rubbing, didn't touch keys, body or fender liners.
  13. Regret your 3/4?

    Came from a half-ton Denali. I miss the comfort and quiet of the gasser. I was right on the edge of safety for the toy that I pull for the 1/2 ton so it was a pretty easy decision to go 3/4 ton and Diesel is just better at pulling. All in all, no regrets, just wish the ride was just a little easier on my old spine, and any chance to get the Duramax quieter I would take.
  14. Nothing beats a set of dedicated snow tires (not severe snow rated tires like the KO2's and others). LT275/65R20 is the way to go for these trucks. Tirerack.com sells a General Grabber Arctic and a Firestone Winterforce LT. Cooper makes a Discoverer and Nokian provides an option too. Either get another set of wheels or have them switched out in the late fall / early spring. About 80 buck each time, or 160 per year for the capabilities of a dedicated snow. In the end, I wish the Blizzak DM-V2's came in an LT rated tire - best dedicated snow tire I've ever used. They make a 275/60R20 but non-E rates, 50PSI max. Would give my TPMS sensors issues and 2,675 lb rating per tire vs 3,195 on factory LT265/60R20's. Weight rating wouldn't bother me as I don't haul anything in winter but the TPMS alerts would annoy the snot out of me.
