I have seen 325 65 18 KO2's (35x13) on a truck in a parking lot, Factory wheels with a level. Factory wheels are also a +27. I never saw the owner to ask about rubbing issues or if he had to make any mods to the fenders. On a side note I've posted this a few time but from my own experience 285 65 18 with 2.5" level and -6 BS clears with no mods. -12 BS rubs in reverse at full lock but can be cleared by Zip tying the wheel well liner back. That being said, If you crunch the numbers... A 325 60 18 is 12.8" wide 33.35" tall and a 285 65 18 is 11.5" wide and 32.6" tall. With 0 BS a 325 sticks out 6.4" from the hub face while a 285 with -12 BS sticks out 6.1". So the 325 on a +0 BS plus the additional 3/8" from the bigger diameter will certainly rub whether it's just the liner or it gets into the fender I couldn't tell you. The other things that play a role are tire manufacture and rim width. When the manufacture specifies a section width like 13" you typically see an approved rim width range like 9-(10)-12 the number in paranthesis is the width they used when making the measurements using a narrower rim will result in a narrower section measurement so the 325 might measure 13" on a 10" wide wheel but only 12.5" on a 9 inch, it may seem small but could be the difference between a slight rub and hitting the sheet metal. Offset is always the biggest factor in whether a wheel and tire combo will clear. One other thing to note is a lot of positive offset with really wide tires you start to run into rubbing on suspension parts namely the sway bar. I've heard of this happening with 305's on factory wheels.

Good to know! Thanks for the awesome response! very informative.

I have 275/70/18 not and i believe they should fit fine on a 0 offset, but the width is my main concern. I will be fine for a while, until these tires wear out, but after that I will be looking to go wider on the tires.

so you guys are sayin that that guys 3" level kit is way worse than a 2.5" level kit? why wouldn't you need all that extra stuff for a 2.5" level?

More than 2 1/2" just seems to put more stress angle wise than 2 1/2" and below. 2 1/2" still puts extra stress on it, but it just seems like once you go 3" that's when the ball joints go out way quicker than 2 1/2" or lower. This is all just from what I can tell by the comments I've read. Just seems like once you go over 2 1/2" that's when you need to start lowering the front diff (if 4x4) and the rack & pinion. Even a cheap lift kit that just has spacers for the front struts on a 4" lift will do the same. It's one of those things that you have to basically draw the line somewhere. I mean would you put a 6" spacer on the struts or would you lower the diff and rack & pinion 6"?

Exactly what he said ⬆️ a 2.5" does cause stress on components but not nearly as bad as a 3". So really you do gotta draw the line somewhere

Been waiting almost a year to get new wheels... couldn't hold off any longer. XD822 Monster 20 x 9 with the Kumho Road Venture AT51 with a leveling kit. Very happy with how it turned out.

Nice setup man! I was debating between 24 and 26in wheels, ended up going with 26's.

2016 Crew Cab LTZ Z71 with 2.5" RC lift with rear block...

 

285/65/18 Nitto Ridge Grappler with 18x9 Gear Big Block 18mm offset.

 

No rubbing whatsoever. Thinking of changing to a 33x12.50 while I still can. Thoughts?

Thanks! Honestly I just got them put on about 2 hours ago but I do love the look of them and for the short ride home they seemed to be just fine!

Has anyone has issues with the dealership not being able to recalibrate speedo.

 

My dealer wouldn't do it because GM said they wouldn't let them access the computer because the wheels I put on aren't GM brand wheels. Seems stupid to me. But it's what the dealer told me. If this is the case, would a shop that has a "tuner" be able to do it? I would hate to have to buy a tuner just for this one reason.

 

Is it even worth it? my stock wheels were 31.6 and new wheels are 31.9

What does the GPS speedometer app on your phone tell you?

    • Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose  
    • I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose  
    • The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.
    • So I purchased the Range unit for my 2026 and I am seeing different locations suggested for the ECM . Can anyone confirm wither under hood, left side or right side or behind the wheelwell?
    • Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
