2016 Chevy Silverado LTZ Z71

[ThundahBeagle]

That's a K1500 you've got there. LT tires are of course very good and very rugged. Might I suggest a load range C as opposed to load range E. The Load range C will be a little bit lighter. Not quite as rugged as an E range but certainly more robust that a street tire.

As for me a recently went with the standard BFG AT KO 2's (probably the last opportunity to by the 2's) and I love them. 285's on the GM steely 17 inch 7 spoke rims. They've been great all winter with very little MPG penalty, unless I put my foot in it

I run LT295/70R18 Falken ATW3 on my 2500HD. Great tire, but those are all big heavy tires. Tires are a big expense anymore. But they sure last longer.

That's a 34.5" tire, not interested....

Yes, that is what the spec says. But in real life I set my speedometer adjustment for 33.25 to read correctly and it is spot on. if I was to do over, I would probably have done the LT275/70R18. Narrower tire in a slightly smaller profile. I have gone through the front end, replacing UCA, upgraded the steering, and shocks. The tires and pickup drive great and it goes where I want it to. I really like the Chevy platform and have driven fleet trucks up to 200K with nothing more than regular maintenance.
I really like your build.

I am currently leaning towards a 305/65R18, that is roughly 33.60" x 12.20"

The current size 295/65R18 is roughly 33.10" x 11.80"

The 305 size is also about $450 cheaper than a 295

Interesting weight increase also

295s are roughly 60-63 pounds each

305s are roughly 68-72 pounds each

......and I'm finally taking the truck to a local dealership on Monday, for the brake vacuum pump/belt replacement

Hopefully there's no issues and it's fully covered!

The service manager said they stock the pumps and have repaired a ton of trucks and SUVs with similar symptoms

 

[D45]

Confirmed failed vacuum pump!

They are replacing the vacuum pump and the pump belt for free, under the special coverage warranty

At my request, they are also replacing the serpentine belt and A/C belt......for $130 total

110,000 miles, I figured whynot, since all the belts are being taken off anyways for the vacuum pump replacement

 

[D45]

All done and back in the driveway

Time to search for tires and deals

 

[D45]

Took a 525 mile round trip venture

some wet trails, the worn out Duratracs still did good and the truck performed flawlessly

Brakes are back to normal and I averaged 17.0 mpg overall

Almost at 110,000 miles and will be ready for an oil change soon

 

[D45]

Another oil change done, new air and a new cabin air filter

Took a 500 mile round trip drive this week,no issues at all

110,000 miles

Need tires soon!!!!

Well the P0700 code and check engine light popped up twice in the last 2 weeks

The trans temp gauge on the dash will fluctuate from 0 to 171 degrees and register all over the place when driving, in 90 degree weather

Based on a quick call to the dealership, they said its likely the faulty trans temp sensor......thats only accessible from inside the transmission once the pan is removed.

N192291660 is the special extended bulletin for the 8 speed transmission to have this replaced for free.

however, it only applies to the 6.2L not the 5.3L. ******!!!!

Its a $1,000 job at the dealership

Dont know for the life of me why it should not apply to the 8 speed transmission no matter what engine it is coupled with, other than maybe there was no class action for vehicles with this combo like there was with 5.3 /6 speed.

That's a "general" code. Could be any number of things. Check with a specialist tranny shop and I bet they know better and can do the job better but for less $

 

[D45]

Yes there's P0700 code could mean many things

In my instance, the trans temp sensor is triggering a no or low reading for the P0700 code

I am calling around this week to get various estimates for repair. I am certain the dealership will be the highest

The special exemption for this sensor covers upto 120,000 miles. My truck is at 112,000 miles, so I guess its also worth a call to the local dealership to inquire why thr 5.3L 8 speed trucks are not covered
