Toyo Open Country R/T Trail vs. Cooper Discover STT Pro?

[Mifsuud]

Recently put 315/70R17 Toyo RT Trails on my Rubicon 4xe. Slightly louder than KO2, certainly smoother at highway speeds. Three of them took 1.5oz or less to balance, one took 3oz which is very little for a large tire. I chose the Toyos in part due to their reputation for balancing without a lot of weight. 315s are load range D and ride quite well even at the 37psi the tire shop used. Slowly adjusting down for the commute. Haven't been able to trail run yet.

For anyone wondering, I went with the Toyo Open country RT Trail, I couldn’t pass up the price. I got 5 tires plus a sensor for my spare and they even paid me for my old tires. Plus I got 26mpg round trip on the 120 mile drive in SoCal traffic. Took very little weight to balance compared to my old mud tires.

I really like the look of that tire. How does it ride being an E load rating?

What do you think after running K02's?
Hard to compare a new tire to worn tires.... but what do you say to the E load rating and tire being stiff?
My 392 will see 80%+ road vs. off-road. I have custom LJ for hard-core off-roading.

My other tires were the same ply rating, so I don’t notice a difference in that aspect. I probably run a little more pressure than I should just because I drive 24k miles a year and like to squeeze out some better fuel economy when I can. They’re way smoother on the road than the old tires. They do make some noise, kind of a higher pitched sound than a hum, almost like they’re singing. It shouldn’t take long before I’m at my first rotation since I drive too damn much lol.

Once I decided on the Toyo Rt Trail then next decision was the actual size 315/70R17 or 35x12.50R17, D or E rating. Per Toyo's data sheet there is .1" difference in height and 1 pound weight difference. Nothing to concern me. Then I checked price and availability. The 315/70R17 were available and less expensive. Decision made for me.

Selling point on the KO2 is weight. It has to be the lightest AT tire on the market. Significantly lighter and BFG has always been known for good looking tires. That said KO2s aren't the best performing even for pavement. Dry they are fine, wet not great IMO, and their soft sidewalls always made me feel more lean on turns than was really happening. The Toyos are more stable feeling IMO. D or E ratings don't mean as much as taking the time to dial in the correct psi for your vehicle and driving habits.

Bottom line: once you are paying $400 each for tires, and most brand names are within 10% of each other on cost, you either have brand loyalty, chasing a look, or searching for the tire that will do what you want. I took a risk supported by local shop recommendations and online deep dives that weren't really out there for the Toyo RT Trail. It's too new for long term data. I had to apply Toyo's general brand reputation to the equasion. I'm happy so far.

How tall is your 315/70R17 RT Trail tire after mounted and with weight of the Jeep?
I measured my stock K02, supposedly 35" (34.5" according to BFG site), mine measured 33.75" with 36psi.
I used a 4' bubble level on top of tire and a tape measure.

Btw, the only proper way to measure tires is unloaded, at sidewall max psi, and with a cloth or other flexible tape measure around the circumference at the max circumference, then divide by 3.14:

https://www.ecfr.gov/current/title-49/part-571/section-571.139#p-571.139(S6.)(S6.1.)(S6.1.1)

That should get the rated tire size for BFG and everyone else. Obviously all tires are smaller under load on the vehicles.

Mine are a hair over 36 mounted on the Jeep, but again I run 35-37psi

It’s also the smallest tire on the market, and the tread looks like someone barfed on the machine when making it. To each their own, BFG all terrains have always looked like an ugly tire in my opinion.

Do you have any type of lift or stock?

Could you please post a pick of your Jeep with RT tires?

If it’s just for wet roads/looks, def stay away from BFG. I ran Toyo OC3 35’s in C load that did fantastic, but they did get loud, otherwise handled great. I’m a big fan of Mickey Thompson Baja Boss A/T as well. I’d try to stay in a D load. E would be fine, but you’d have to air down to around 25psi and be prepared to not have good mpg (not that it matters with a 392 on 37’s ?). As long as you get a tire with good wet traction, there isn’t really a wrong choice since you don’t need a 3 peak snow rated one or go off-roading.

If you’re asking me then yes, I have a 4 1/2” lift on mine. It’s a Gladiator though. Haven’t been able to snap day pics really since I work till 10pm

on a side note these did amazing in the rain today. I feel like they don’t spray cars behind me as much as my MTs used to

I'm looking for a modern, more aggressive looking tread pattern 37x12.5R17 for my 2023 Wrangler 392 XR.
Currently have the stock 35" BF Goodrich K02 all-terrain, looking for a more aggressive, modern looking tread.
I live in FL, so no snow, but wet roads are mostly daily 8 months out of the year.

The two tires I like the look of are the hybrid Toyo Open Country R/T Trail and Cooper Discover STT Pro.
Have heard the STT is a round tire that takes little weight to balance?

Weight of the tire is a priority, wanting to stay as light as possible, sub 80lbs.

I've looked at most all of the tires on the market currently, haven't seen any all-terrain tire that have the aggressive tread I'm looking for. Was hoping the new BF Goodrich K03 may fit the build, but unfortunately not.

This is not my hard-core wheeling Jeep. Manly on-road use, but want a more aggressive look.




Anyone have experience with either of these tires on a Jeep?

Smooth on-road ride is a must.



Toyo Open Country R/T Trail:
- Weight: 75 lbs.
- Load rating: E (seems a bit much for a JL?)
- Tread depth: 17/32"

Cooper Discover STT Pro:
- Weight: 77lbs.
- Load rating: D
- Tread depth: 22/32"

Bit of a late reply, but I had to wait for the KO3's to become available. Ordered a set of 5 last month, had them installed and I am just thrilled at the difference. I ordered the 315's and they are amazing in the rain (I also live in Florida), its like having a wave runner for tires. The reviews are spot on: much quieter ride, smoother over pavement and incredible in the rain. If you haven't purchased yet, I highly recommend the BFG K03's.

I just may agree with you, however I think I’d go with 37”. Not available for a couple of years, from what I’ve read.
