275/60 vs. 275/65 another tire thread need opinions

crushNchowda · August 5, 2016

I know this topic has been beaten to death and then some, but I'm going to pull the trigger on some better tires for my '15 CC 6.2 which already has bilstein 5100's @ full height & an extra 1.25" in rear blocks - I was dead set against going w/ 275/65r20 or 285/55/r20 due to the substantial increase in weight & the coinciding mpg/performance drop, but w/ how expensive a new set of tires is I also don't want buyer's remorse wishing I just went w/ the more aggressive/slightly taller 275/65r20

Narrowed it down to the following for 275/60's that aren't super heavy:

Wrangler duratrac in 275/60 is 46 lbs but is 57 lbs in 275/65

Nitto Terra Grappler in 275/60 is 42 lbs but 59 lbs in 275/65

BFG KO2's, which I want, are nearly identical 275/60 is 55 lbs 275/65 is 57 lbs - may as well go w/ the 275/65 if going that route

The stock wrangler SRA's are 39 lbs FWIW

I do have an extra set of black 20"s that are about 8 lbs lighter each compared to the 20" AT rims, I did think a compromise would be running my winter tires on the stock wheels & running the heavier AT tires on the black granite alloy 20"s instead...they're a few years old & could use some clenaing but look good

So - has anyone gone to 275/65 on the stock rims & really regretted the performance/mpg drop??

Hands down the BFG's are the best looking IMO & I already know they wear/ride well.

M Y TRUCK IS 4X4 6.2 whatever standard gearing it comes w/ I'm guessing 3.23 or 3.42 w/ 8 speed

275/60 = 175, 275/65 = 179.4. 4.4x2=8.8. It is a total of 8.8 millimeters of wheel width.

I was thinking this same thing for 2 weeks. I was changing wheels to Fuel Savage same specs as stock 20s. I had decided to run the Michelin LTX MS 275/60/20. Mounted them after the RC level and hated the look it just looked weak with the street tread design.

I gathered a set of BFG KO2 in 275/65/20 hoping for no rub and no noise ride complaints. Mounted them and only had to tie the rear inner fender liner back and it was perfect no rub. Once on the street I absolutely love the tires, sure a bit of noise that can be easily drowned out by a slight radio volume and yes you can tell they are 10ply AT tread as you feel it a bit rougher. With that said the perform on dry,wet and cornering incredible! They far outperform the crap Goodyears which left you scared anytime driving in rain and felt like jello in corners. Wet traction is insane! I was traveling back to FL when a downpour hit,I felt so stable even in flooding waters.

So to sum it up looks are hands down the best,performance is incredible compared to other AT brands I have run and I have run a lot. I have noticed a 1.5mpg loss at h/way speeds only over 75 mph under that about the same. Speedo is off 4 mph now.

My background is in auto repair and customization as I own a shop in Knoxville TN doing Jeep and other Truck SUV work. I have run all brands from Goodyear,Nitto,BFG,Bridgestone,Continental,Hankook and others as we are a dealer for all tire brands and for the tire size the BFG is hands down the best!!!

Forgot mine is a 2016 SLT 4d 4x4 had the factory 20 chrome clad wheels.

Thanks for the comment, actually checked back on this old thread as I pulled the trigger on some 275/60R20 BFG K02's last week that I won't install until the spring since i run a winter tire/wheel setup (layaway @ a local tire shop).....but I had recently found out that my winter rims are 8 lbs lighter than my stock 20"s so I'm swapping snow tires to the stockers & will run the BFG's on the ligter aftermarket wheels to help offset some of the weight gain, instead of adding 17 lbs per corner it'll only be 9...I'm sure I'll still lose some mpg but if they're going to fit no issue I'll take the extra 1/2" of ride height over the 275/60's if I'm only gaining 2 lbs
