Hi All,

I have a 2022 Trailhawk brand new and I'm in Australia the only sell the car here with normal road tyres no A/T.

Anyway I ordered and purchased the HS 2inch lift which I just installed and now I want to upgrade my tyres. With the tyres I wanted to key some BF goodrich K02 in the size of
255/70/R17 does any one have this size and do they fit with out any modifications to the wheel wall??
Here is a photo of mine lifted with the road tyres it comes with.
Thanks and if anyone has any photo of their cards with this tyre combo I would love to see the pics. View attachment 220239

Welcome from Utah, USA!!! 245/70/17 is the largest tire you can fit without trimming the lower front wheel well area. KO2's are a great tire, but they are very heavy at 50lbs each since they are an LT rated tire. I personally run the Toyo A/T III's that I've found are very comparable, but much lighter at 37lbs. Another popular tire down here are the Falken Wildpeak AT3W. Search around the forum and you'll find many lift and tire threads...😎

cannot really find many running the tyre size of 255/70/R17

That's because it's not a very common, or manufactured size in the A/T category...😎

Also how do you rate the Toyo A/T III's? and do you this the KO2 are too heavy for a TH?

I rate them excellent. Very tough and capable, but also very street friendly, and their 60,000 mile warranty isn't bad either. Another tire that has peaked my attention are the Maxxis RAZR AT. Seeing some great reviews on them as well, and they will probably be replacing the KM3's currently on my Can Am X3 XRC when the time comes...😎

Toyo

Maxxis

I have also seen the Maxxis RAZR AT and have them on my list as a possible candidate, what is their weight like compared to the KO2s?

Same as the Toyo‘s, Falkens, and most other non LT rated, all around 37lbs in 245/70/17's. @Mark_ they are not available in 255's, in fact they are pretty limited in smaller sizes all together...😎

 

[Flybynightcru]

Actually, with the Maxxis, you would actually run the 265/65, as they are not available in a 245/70, but they would be almost exactly the same as a 245/70 once mounted up, and should fit without issues. 30.7" compared to the Toyo 245/70 at 30.6", both 37lbs...😎

 

[Flybynightcru]

Thank you to you and everyone else here for all the great advise, what would you suggest be more beneficial for off-roading the 265/65 or the 245/70? would they both give the same amount off lift and if so how much 1inch?

Also what would everyone consider as the holy grail of A/T tyres for a TH these days?

There's only a tenth of an inch, or less than 3mm in the diameter height, so virtually zero ground clearance difference between the 245/70 and the 265/65. Any of those are top of the line AT's, and all excellent choices for the Trailhawk. I'm not sure where you are located down there, but my one trip down was to Queensland, and I would compare it to our Southwestern US as far as climate goes, pretty dry and dusty most of the time, and you don't have snow to worry about. Again, all great choices, and let us know what you go with, and do post pictures...😎

 

[Flybynightcru]

Also worth asking why do you feel the heaver LT tyres will not be good for these cars? gas mileage or extra strain on the drivetrain?

Both fuel mileage, and wear and tear on a somewhat delicate drivetrain to begin with. That's just my opinion. Better safe, than sorry. PTU's, axles, RDM's, suspension, and steering components ain't cheap nowadays...😉😎

 

[Flybynightcru]

Well noted, do you believe in your opinion 245/70 with some non LT tyres will hold up just fine for the long term?

Absolutely. Any quality A/T from the above mentioned will serve you just fine...LT (stands for Light Truck) rated tires are designed for trucks, and much heavier vehicles that haul, and or tow much heavier gross vehicle weights than our Cherokees...😎

 

[Flybynightcru]

I wouldn't even put LT's on a Jeep Wrangler JLU or Gladiator. The damn things already drive like an old dump truck that you can't even haul dirt in...Well, I guess you can put a little in the bed of the Gladiator...LOL!!!😉😎

 

[Flybynightcru]

I've heard through the grapevine that it was a problem with 2019+ Trailhawks?

Fake news...😉😎

 

[Flybynightcru]

Yes they are, but actually they are a very good hybrid, with more of a street friendly look for someone not wanting an aggressive looking A/T I guess...Great tires though...
Which ones look like the "real A/T" to you???
Yokohama GO15

Toyo A/T III

Maxxis RAZR A/T

 

[Flybynightcru]

One would think they would at least come with the GO15 A/T, or at least the same Firestones that we got...Hmmm...🤔😎

 

[Flybynightcru]

My thoughts exactly, if they had I wouldn't have to make this post I guess. Took the TH on the beach today no issue at all with the highway tyres...

Did you have to drop the pressures at all???😎

 

[Flybynightcru]

No I left the tires fully pumped up yesterday as the sand wasn't that thick but in softer sand I go down to about 15 psi otherwise I will bog down. Also How do you rate the toyo A/T 3 against the wildpeak at3w i've now narrowed it down to these two tires.

Well, I'm probably a little more partial to the Toyo‘s, since I run them, and have not run the Wildpeaks. Do a quick Google search, Toyo A/T III's vs Falken Wildpeak A/T 3W. There's a few pretty good comparisons. The only negative I've seen with the Falkens on other people's vehicles is they seem to chunk the tread a little bit in our high desert rocky terrain here in Utah. You really can't go wrong with either one, they're both excellent all terrains...😎

 

[Flybynightcru]

The toyo A/T 3s just got released in Australia this week not sure how long the US has had them the come in the following sizes

245/70R17	119R
265/70R17	121S
285/70R17	121S

Wow, we've had them for at least a couple years. I've had mine for a year. Not many sizes available down there either, but you have what you need, 245/70's...We have every size available, even LT's, and XL's. I run the non LT 110T...😎
Looks like the 119R in 245/70 is the LT. You don't want those, way to stiff, and heavy. I would call around and see if you can find the standard 110T...😎

Try this website. I have never purchased through them, but they have excellent tire reviews, tire, and test data for literally every tire on the market, at least here in the US...😎

Another good distributor site with plenty of reviews on every tire on the planet...😎

Thanks for that, I went to see a tyre shop today and they advised the following.

If I go 245/70/17 I would get roughly a 1 inch lift over what i have now this is with the wildpeak at3.
If I go 255/65/17 I would get roughly a 0.6 inc lift and more width

The guy seemed to know what he was talking about and said he fits these tyres all the time. Do you guys think what he said is right on the lift between these two sizes?

@Mark_ is correct. 245/70's will give you another half inch of ground clearance. So with your 2" lift, and the 245/70's, you gain roughly 2.5 inches of ground clearance...😎

This is what I have at the rockers. I'm 12" and change at the lowest point of the skid plate...😎

 

[Flybynightcru]

Also will the 255/65 spare fit in the wheel well like the 245/70?

I don't know. The 245/70 is tight. The extra width might not let it close completely flat, but I'm not saying it won't either...😎

 

[Flybynightcru]

I agree with what Mark said. I personally wouldn't run anything bigger than the 245/70's, even if we could fit much larger tires for a couple reasons. First one being, they fit without any modifications, and leave plenty of clearance for things like mud buildup, suspension travel, and articulation while offroading. Then the biggie is added wear and tear on the drivetrain, suspension, and steering components from larger, and heavier tires. Even though there's virtually very little difference between the two sizes, I've come to the conclusion from my own experience from 50 years of offroading, and from other folks experiences around here that the 245/70's are just the perfect size upgrade for our lifted 2019+ Trailhawks for performance and reliability...JMHO...😎
