Finally pulled the trigger on new tires today.  Went from the factory 265/65/18s to 285/65/18 Yokohama Geolandar X-AT.  My son got them at his shop at a great price.

 

Great fit on the stock 18s with a Rough Country level.

GPS shows 51 mph at 50 mph speedometer indicated.  I can live with that.

Surprised it's not a bigger difference.

How was it reading before?  Was it spot on?

Bigger tires than factory should mean that you're actually driving faster than reported on the cluster, isn't that right?

These tires are the same height as stock so speedo should be really close. They are just wider then the stock.

Good look and I like the 285s on the truck. 

Currently running 275 55 20 from my sold off 2003 Sierra Denali. I couldn't let go of my forged Centerline Tomahawks.

 

Originally had 275 60 20, which went to the SD and think I'll be going back to a 285 60 20, if my Nitto 420s ever wear out.

The Yokos are 1” taller than the 265 Wranglers, at least to the calculator below.  Speed difference varies as speed increases.

Looks good...definitely a bit more aggressive looking!

 

How do they sound out on the road?

Not too loud.  Definitely not as loud as a pure mud tire, but just slightly louder than BFG KO2s.  They may quiet down after a few miles to break them in.

 

I will say they have a stiff sidewall.  Much harder feel going over speed bumps at 33 psi.  Could be that my Wranglers were wore out too.

So far avg says about 1 mpg less.  Given the speedo is off about 1 mph, that could be the reason.

 

Honestly, I haven't driven but about 50 miles since I put them on.  Chillin and grillin all weekend.  Back to the grind tomorrow so I'll get a good sense on in town mpg this week.

So after 3 days of regular mixed driving about town...some interstate, some downtown, lots of 55-65 mph stop and go  highways...I've averaged 15 mpg.  The Toyos are heavier than the little Wranglers I took off, so I guess it should be expected.  I won't know long trip mpg until next month when I have to drive to Orlando.

      2027 GMC Sierra: Official Discussion

      Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

      - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
