BFG K02 vs goodyear wrangler all-terrain for noise/comfort

I love the Goodyear's that came with the truck. But, I have an opportunity to grab some different tires for cheap (my dad needs new treads and I can sell these Goodyear's to him for a decent price).

Ive been eyeing the bfg K02s.

How do they compare in terms of (strictly compared to the GYs that came stock):

1. Noise
2. Ride quality (the Goodyear's are smooth and soft on pavement)

I already have enough vibes and howls coming from this truck, so I don't want to switch tires to be greeted with a new hum or howl driving down the highway.

Also I will be keeping the stock wheels. Should I stick with stock size 265/70/r16 or do the 265/75/r16?

 

I don't have either.

I ended up with the General Grabber AT2 as input I received here was that it was almost a copy of the KO2 and rode quiet. They were about $50 cheaper per, look pretty good, and for an AT, they weren't much louder than the passenger car tires they stick on the SR5 with steel wheels. The ride isn't much different.

 

BFG KO2 came stock with my 97 Defender. Amazing looking, not so good with the gas mileage and noise was unbearable. Of course the Defender had soft top so at hiway speed you wouldn't care what's what.

 

Oh, I did loose 2-3mpg going to the AT. It's a heavier tire.

 

I went from the stock Rugged Trails to KO2's. I think they're quieter and smoother, to be honest.

 

Depends on rating as well as KO2 come in C rated or E rated.

I went for the C rated over the E rated. No complaints!!!

 

They're going to be louder than the stock Goodyear's that are currently on your truck, since they're more aggressive. I have the Grabber AT2 which is similar and they do make some noise but I don't care. Since you're going from a P rated to an LT they're going to ride stiffer too. If you love the stock Goodyear's then just keep them until they need to be replaced. Going to a heavier tire is going to cause you to loose some MPGs too.

 

If you are really concerned then you probably don't want an A/T tire. That said, the KO2 in Load C is a good fit for the Tacoma. Run around 35 PSI up front, 33 in the back. You will lose about 2 MPG on the highway. Mine ride nice, comfy and are plenty quiet. I'm very picky about vibrations and noise, the tires have neither. They are MUCH better than the older KO's I've had on other vehicles.

 

unixadm, running 36 all around. May drop it slightly see if I notice much

 

Leave it to TW to give me conflicting information.

Most of the reviews on tire rack and elsewhere are claiming how quiet and smooth these things are..even for an AT with aggreasive thread patterns.

They are only 10lbs heavier per. Would that have as much on an impact on my mpg or is it more related to the thread pattern? 40lbs more weight seems entirely negligible (unless I'm not accounting for some physics wizardry where wheel weight is exponential blah blah).

 

I actually agreed with that assessment, and I'm running 285/75/16 E TA/KO2 vs. stock 265/70/16 C Rugged Fails. Even at that, the TA/KO2's seem smoother and quieter.

I may be wrong, but my understanding is that a heavier weight tire is harder to get moving, but easier to keep in motion. So, a heavier tire would result in better mpg on a highway, while a lighter tire would be better for around town. I don't think tread pattern is an issue unless you get into mud terrains.

 

10 lbs per corner is a significant increase. You might not notice a loss of power but you will probably notice loss of braking ability and the ride will be rougher, not just from the stiffer sidewall, but also from the shocks decreased ability to control the weight of the tire and wheel.

 

I went from the stock Goodyear ata with Kevlar to my new BFG AT KO2, Though going from a 265/70r16 to a 285/75r16, I noticed no sound increase whatsoever, and I know have a stiffer ride. Raising my truck 3 inches, the 10 ply of the tires I chose, does hold well in curves even with a raised center of gravity. I really enjoy them, and I have no trouble with sound or smooth ride.

 

Yeah you're going to loose a couple mpgs because of the additional rotating mass which is greater than if it was just 40 lbs in the bed.

 

I didn't mind the stock goodyear tires, but had a brand new set of KO2s (2000 miles on them at the time) sitting in my garage from my last vehicle. I notice no increase in noise, seems to have no diminished handling or braking. Only dray back is a loss of a couple mpgs.

Mine are 265/75-16

 

You wil get better information here than the tire rack reviews, as we all drive tacomas, and there are tons of people on here with both those tires. There are threads dedicated to the BFGs, search and you will find lots of good intel.

 

If you already think your truck should be quiet like a Lexus then stick with the oem tires the K02 are louder ( I like it personally ) bought a truck to be a truck or I would have bought another Pilot except now they are super Fugly!

 

Yes, it matters. Yes, there is physics wizardry. I'll explain below.

A heavier tire results in better highway mpg? Did you think about that before your wrote it? When does anything being heavier make better mpgs?

Force = Mass X Acceleration
Acceleration = Change in Velocity/Time

Normally, we think of Velocity as just speed, but in reality Velocity is speed in a direction, or a vector. Changing that direction is a change in velocity. Based on this rotation at a certain RPM is acceleration. Please note, a car going down the road at a steady 10 miles/hour is not accelerating, but the wheels are since they constantly change direction by rotating.

Since rotation is acceleration there must always be a force applied based on the Force = Mass X Acceleration equation right? Can a force be applied without some energy behind it?

10lbs per tire is a big deal..... why do race cars go to lightweight rotating components even if it only saves minimal weight? F=MA!!!!

 

1100 mi. on my truck. Switched to the load C bfg ko's. 265/70/r17. No noticeable change in power, braking or noise. It is a bit stiffer. Not bad, just noticeable. Went from 21mpg per tank to 20. I think with the load E it would be more than I would care for. BTW, they look way nicer in person. I could never go back to stock!
