I'll be posting a video soon about the tires I took off and the tires installed today.

Looks great! I’m wanting to do some similar tires. What brand/ tire did you go with?

 

[TARDIS]

Radar Renegade AT5
285-75-16

Set at 38psi


After One Day and 80 miles, I found the set to be:
Quiet (for an A/T or aggressive HT)
Comfortable on the road

And overall my 2 door Yukon feels like a more confident and planted ride on dry road.

I am still breaking them in, and will do a short video soon.

They look great on the truck, and clear the fenders without rubbing at full turn.

Your speedometer is more off now isn't it.I have 265/16 on mine right now and I don't like that speedometer is off.on highway speedo has 65 but feels like 55 mph

 

[TARDIS]

The speedometer is incredibly close to accurate MPH.







This chart shows you the difference in OEM (265/75/16) and my current tire set up.

At most I am only 3 MPH over at 70mph.


Luckilly, I also run a digital screen from my OBD2 that gives an exact MPH by callibrating the size of the tires.

What pressure do the sidewalls list as the max?

 

[TARDIS]

3750lbs Max at 80psi

10 ply, E



I'm currently running them at 38psi, until I can do a real chalk test.

Sidenote: They feel great, with minimal road noise.

The KO2 10 ply E have shown good results at about 50 lbs. Curious to see your chalk test.

Each tire maker lists a nominal tire diameter when mounted on a specfic rim width. You have to check what the maker of your specific tires lists for diameter and what the measuring rim width was.

Hypothetically, it's possible to have a 265 mounted on a wide rim be the same as a 285 mounted on a narrow rim, or that they'd be closed to each other.
