What tires did u put on?

36 front tire pressure?

 

Teeko - Yes. 36 psi front according to my dash readout so it would be considered "warm" pressure but the day was cold. In theory, the higher the pressure the harder the tire the least rolling resistance, think of a steel roller skate wheel, requires the least horsepower and hence fuel required. But, the harder the tire the harsher the ride. So it is a compromise. IMO.

 

Okay sounds like what I'm running.
I set mine to 35 psi while cold and once I'm driving I see them come up to 36 or 37.

Some people run them at 40 but wouldn't that be considered over inflated?

 

I had bad experience with E load rated tires on small trucks. Hopefully, that's not gonna be a problem.

 

Gabor - What was the problem that you ran into. I would have preferred c rated but BFG does not make that in a 16 inch but they do in a 17 inch.

 

Are C rated lighter? Or smaller in size?

 

It resulted in a stiffer ride, and they went out of balance too quickly. Since the tires are more heavy, they require more weights to balance them.

 

C rated tires are lighter and require less air pressure.

 

C-rated has 6-plies vs 10-plies in a load E.
Therefore, it's max air pressure/max load rating is less.

 

Splitbolt's answer is more correct than mine. I did a bit of reading and found this:

So what’s the difference between tires of the same size but different load ranges?
It’s no longer the number of plies. Most radial truck tires, for example, have a total of five plies. There’s one steel body ply and four belts under the tread. What is different today is the strength of the steel cables in those plies or the number of cables per inch. We’re now at the point where we no longer add more and more plies, but instead, adjust the strength of the entire casing to achieve the desired load capacity.

As I understand it, tires are nothing more than a container for air.
Tires need a certain amount of air volume to support a certain amount of weight.
The easiest thing to do to change air volume is to change the air pressure.

All things remaining the same, when you upsize a tire, you do not require as much pressure to achieve the same air volume/load rating.

Yeah all stock, no issues at all.

 

So what are people expecting to get out of the KO2? Mileage?


Good highway tire?

 

My mpg went down dramatically with my 285/70/17 KO2's
It's worth it tho, unless I can find a tire that is the same size but lighter in weight.

 

I get 15.3 now. What are u getting?

 

TacoSeattle what kind of a hit did you see going to those tires. I'm probably gonna run the KO2 in 265/75/16 but they're 53 lbs compared to the GY OEM at 36. That's a lot of unsprung weight added. I pick up my truck this week, so if I drive it right to the tire place maybe I'll not notice lol.

 

That tire is more then my wrangler duratracs at 48.5. And those are 285 70 17

 

Ugh, I thought he was running the KO2 but I see he's running Duratracs. My bad. Yeah the KO2 is pretty heavy. Edit...I misspoke, the 265/70/16 OEM GY is 42lbs.

 

Well with mine I'm averaging 275 miles to the tank. That with a 50/50 driving conditions. I'm also trying to be very light on the gas. If I do my calculations for the tires I'm getting like 16.2 really.
