BFG AT KO2

[310racing]

Got a set of 285/65r18. Ride nice, look great. Stiffer but totally expected.

Will try to post a pic later, it's NASTY here today.

How do these affect gas mileage? First time poster, and after reading the lifted/tires/etc post someone started last week, I'm kinda terrified to do anything to my new Sierra. I love the look of these, and I know i want to get some wheels and new tires, but again if it's gonna dramatically change my MPG, I am happy with the look I have now.

Santa lifted my truck and gave me these tires in 275/60R/20's. Yesterday I drove it 560 miles and averaged 20.1 MPG. This is with the air damn removed and the lift. 6.2 engine and 70MPH average on interstate 5.

What side steps do you have on your truck?

GuapOh, how is the ride and noise of the new tires compared to stock tires?

[310racing]

 

Just put a set on mine, ride stiffer but handle well, balanced well.

 

Got a slight roar, but not bad at all.

[diggman08]

are these louder than the original KOs? Would you get the originals over these KO2's if you could do it again?

[EXSlider400]

Those look great!

Are these offered on 275/70/18? That size isn't on their web site but the guy at Discount Tire said they were available for $242/tire.

I also like the white lettering but find the ko's are not aggressive enough. So I run these

I just ordered a set of 285/65r18 yesterday. I'll be sure to post pics once I get them mounted.

These tires are sweet, have the same question as a previous post.

Can these be installed on a stock truck, or is a lift required for them to fit.

[310racing]

Mine are 285/65r18, fit fine, no rub or issue.

 

These are alittle louder, but seem to be a better rubber, handle great, and should be alittle better offroad.
