Thoughts, experience with ST maxxx, ko2s, nitto grappler g2s

I like the ST Maxx a lot right now. I have around 10,000 hard miles on mine. Ill bet less than half are highway miles. The rest are in the dirt. I don't know of anyone that has reported such use of these tires. Maybe some of the hardest reported that I know of. The last 9 months the truck was here:

1)Moab 3x - 12 days total-BHTR, FIM, Golden Sike, moab rim
2)High country in Colorado 20x-30 days- talus roads, sticks, mud
3)Choke cherry canyon 6-7x- extreme rock crawling-only matched by Pritchett
4)Toyota Jamboree Colorado-3 days forest road and one rocky rocky roadI'ill never do again called Iron Chest(not hard just pointless)
5)Snow wheeling 6-7x- always perform
6)Ski area 3x-extreme ice, slush and pow

I've aired the tires down many many times, only rebalanced them once. Gas mileage has no bearing on my decision making. They don't seem heavy to me. My truck moves them just fine as you can see in some videos I have. I typically drive in 2wd as long as I can. So in my videos I am in 2wd travelling quite easily to and from the ski areas. Sometimes I may have to put in 4wd once I get to the parking lot. The tires do really great on hardpacked snow and in slush. They give you some warning to before they break free, so its easy to stay in the sweet spot with throttle. After all the hard use I've put on these tires in very hot conditions, I'm impressed. The lugs have started to round just slightly but it hasn't affected performance at all. The duratracs I had before looked much worse after much less use.



They do great in deep snow also. You can see even when I get stopped, I can back up and get another run at it. As long as I didn't spin the tires they kept pulling. The set of tracks I'm following are from my friend with 39's. You can see on my tire how deep the snow is.

I've got 255/80r17 ST Maxx on the F150, so no rock crawling for me. They've done well though on dirt/gravel roads, light mud, in hub deep snow, over icy mountain passes, and I drove through a couple decent deluges in Oregon this last week with no hydroplaning and no need to check speed. Probably near 2000 highway miles on them just this month and I've got no complaints at all.

WAY better than the Duratracs on the Wiferunner. They're quieter, they're wearing better, less drama in the sketchy stuff, and cheaper too.
 
I think I'm leaning towards the Cooper ST Maxxx at this point. Thanks all for the input, it really helps hearing from real life experience.
 
We are running the ST Max in a 255/75/17C...Have about 25k of HARD miles on them so far. MOAB/Ouray/Uwharrie etc. I will DEFINITELY be using this tire again, but will probably get 285/70's next time.

Another vote for the S/T Maxx! Love them, they do really well down here in the desert SW with all the rocks etc!
 
Another vote for the ST-Maxx, they been an amazing all-around tire for me. I'm
running them at 43 psi. I would like to dyno my 255/80 to see If I have lost hp/tq since I had no major change in mpg. I have looked at TheWraith's build and he lost some power with 285's. I don't have any thoughts for them in winter because I have another set for winter. They're probably good in winter if it doesn't get too cold like we get up north.

Why the switch to 285/70 over the 255/80?

K, where did you buy your Cooper's, if you don't mind saying.

I'm tire shopping for the 4Runner, but haven't decided what to go with, yet.

I'm debating the KO2 and ST Maxx. Snow performance on the ST Maxx is Pretty Impressive. I want a Good Snow tire to Play in Northern Az. BFG is Good in the Snow as Well. Going up to a 275 from 265.
 
You’re getting good feedback from members here. I can only attest to my experience going from the stock TG’s to KO2’s.

To the OP, first you need to accept this: You know that nice, smooth, magic carpet ride you have with the TRD Pro?? Kiss it goodbye with E rated tires.

You’re sacrificing some on highway ride quality and acceleration for stability and peace of mind in sketchy and sharp trail situations. To me it was worth it (except when I’m trying to pass a big rig on a grade).

You have to think long and hard about your specific needs.
 
That's one of the concerns, is the ride quality is great right now. Is the ride quality really night and day between the Terra grappler on the TRD Pro, compared to the E rating on the Coopers or BFgs? Great info so far, thanks!
 
I put KO2s on my 4runner and have very mixed feelings about them. They have been great in dry and highway usage as well as gravel road situations, but in the wet, they honestly sketch me out. They are very slick and I am second guessing my purchase. I have Dura-Tracs on my FJ and they have been amazing in all situations, including semi-deep snow. I honestly would not purchase the KO2s again.

I'd have to agree. I've run them on three different vehicles (3 times stupid, I guess)-not the KO2s, but the plain KOs. Absolutely great tire when brand new, but I had hydroplaning issues in all 3 vehicles. As the KO2 tread pattern is pretty much identical to the KOs, I won't be installing these. Ever.

It IS noticeable on and off road. There is not much difference in road noise, however you can feel more of the terrain, like bumps, rocks, ruts; more harshness of ride. The Coopers and the KO2's are heavier, thicker, harder tires. Its a trade off with ride quality. I've been experimenting with varying tire pressures.

I don't now how different the TG2's are from the TG's. Are those (TG2's) Pmetrics?

The TG's did not instill me with confidence in: steeper, off camber terrain in sand or loose dirt and gravel, or terrain with nothing but sharp rocks.
 
Yeah, I don't have great confidence in the Terra Grapplers either. I do like them better than the stock tires on the other models though.

I've had the BFG's for 3000 miles and Duratracs for 80k+, and I can honestly say that the Coopers have been quieter than both. Especially compared to the duratracs!
 
Anyone try out the Open Country AT2's?

I haven't, but a good friend of mine has a lifted Taco with a RTT, camper top, drawer system, and he absolutely swears by them. After riding with him I can only tell you that they're quiet, roll smooth, and can handle some serious abuse.

West Valley Big O. They can't balance a tire and don't use torque sticks on their impact guns, stay away. :D
