Will it Fit Guide:

These are all sizes that will fit our trucks stock or with the correct modifications listed next to the size.

I hope this becomes a useful tool for everyone. This is strictly a guide, not an end all be all. Full disclosure: there will be some variation between tire manufacturers, lift manufacturers etc.

This is a live tool I am constantly updating and need more information to continue growing it. I have mostly focused on stock size wheels, but would like this to eventually grow into a comprehensive chart for other configurations. If you have set ups not listed here (or is on here, but you have more information) that you think should be added let me know.

Please include all information for your setup.

Version 1.0

Pretty cool idea. I'll contribute, since I have 17's, which is less common. 

 

285/75/17 will fit on the stock 17's, at stock height, with GM mudflaps, and no trimming. I ran those for nearly 5k miles, without any issues. 

 

285/75/17 will fit on 17x9, +18mm, with 7 cranks on the stock keys (1.5"), without any trimming and GM mudflaps.

I too run 285/70/17 on stock rims with no rubbing. I started with the truck stock and have plenty of room....now how they keys turned up some and could clear much larger.

Thanks Big Whiskey. Your post on another thread is actually where I verified that the 285/75R17 would fit! I appreciate the info, I’ll add to it!

I should be pushing out a new update later today. Any other inputs, notes or corrections? This will be update v1.1. It should clarify some things as well

I see you have info on 275 65 20 on a +15 offset wheel requires trimming of mud flaps. I have 275 65 20 on stock +44 wheels and they fit without trimming. I previously zip tied the fender liner a little tighter to the frame on both front fenders for my other wheel set up so I'm not sure if that was required or not for the 275 65 20 on stock wheels. I guess I will add my other set up is 275/60/20 on +18 wheels and they fit with no trimming either.

What is "bags on rear" on the chart for size 305/70/18? What does that mean? I have a 2018 2500hd 4wd. Will have a leveling kit. Want to keep stock wheels.

2015 GMC 2500hd cc 4wd 2in level, nothing trimmed and front flaps are still installed. Wheels are fuel sledge 18x9 +1. My last set of tires were 285/70/18 open country mt. They rubbed only at full turn, mainly for about the first 20k miles. I just installed a set of 285/70/18 ridge grapplers and they have plenty of clearance. After looking at the way the tread pattern is on them, I bet I could have fit 295/70/18 ridge grapplers. I'm bummed that I didn't try one of that size first. I had a set of those tires already waiting for when my new 18x9 +18 wheels showed up. I figured coming in 17mm would allow me one size larger. Long story short is that 5 sets of backordered wheels later, I gave up and just replaced my existing 285's on my existing wheels that were just going to be an extra set in my garage. I guess ridge grapplers must clear a little better for their size compared to the open country mt. Hope this helps the next guy questioning a similar fitment

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.
