20 inch wheels on a crew


Recommended Posts

Posted

Now that we've throughly hashed and rehashed the 20 wheel question (on a separate thread) I'm beyond who's at fault and what should GM do or not do about the problem. Now I would like to try and figure out the real issue. He's what I THINK I know so far: #1 there is a problem. #2 GM does not recommend using their 20 inch wheels on the 1500 crew. #3 usage may/could cause a problem with the suspension or frame. #4 usage most likely would void the factory warranty as it relates to the frame or those specific suspension parts. #5 GM has not recalled any crews that were sold with the 20 inch wheels.

 

Now the information I don't have but would like to. #1 How serious is the problem and is there a safety issue with the larger wheels? #2 why hasn't GM recalled the crews that are already out there with 20s on them? #3 Are GM's recommendation and service bulletin just a CYA (Cover Your A$$) thing? #4 If they are just CYA should I risk putting the 20s on my truck anyway (I only use it for light hauling and towing)? #5 how can I find out what the real issue is so maybe I could address it myself by beefing up the frame, or ??? #6 If GM's 20 inch wheels cause a problem will aftermarket wheels? 18s?, what are my wheel options?

 

I guess if I could boil all this down the bottom line is I would still like to put 20s on my truck even though GM says there is a "durability" issue. Should I risk it? :D

Because there is no process in place for the dealer to notify GM which vehicles had 20" wheels installed on them. Therefore, they would not be able to recall vehicles they don't know about.

Big deal, put them on, and if there is a problem, put your stockers back on and deny you had 20's on to the dealer, you seem hell bent on finding a way to run the 20's so this is your way to it.

For sure one way to do it...as long as when it happens it doesn't cause a major accident where you don't have time to change them out. I doubt that will happen though.

I guess that's the real bottom line. Is there a safety issue? If I knew it was safe and it was only a waranty thing it would be no big deal.

    • Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver. 
    • Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....  
    • 4 low is really nice on steep boat ramps. 
    • Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.  
    • Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
