Cooper Discoverer ST Maxx 255/80/17 Skinnies

Just a heads up for anyone researching these tires:

I love the look and performance, but the pull to the right with them is a pain in the ass. I'm going for new tires this Tuesday, gonna try Pro Comps.

I had researched these tires prior to purchase, and had noted that one person had a problem with them pulling as well, but that seemed insignificant. Well, after installation and a few months of driving with them, I looked further into it. There seems to be about 25% of the guys running them having problems with a pull to the right (that number came from a poll on a tacoma forum)

The problem seems to cross platforms as well since I saw guys with wranglers having the same issue.

That being said these are amazing in the mud and rocks and I have no worries about a puncture leaving me stranded in the mountains, but I spend more time on the road than in the mountains.

My 4r is a 2014 trail with Toytec 3" suspension lift, oem trail wheels and JBA UCAs. My alignment numbers are perfect (even the caster since the install of the JBA UCAs).
 
Love them!

I looked over at TW and that pull to the right seems to be a big issue there. I haven’t heard it much here on t4r.

Edit: I finally did some driving today, city and highway. Mine definitely pulls to the right as well. So add me to the list.

[MENTION=78909]alexb[/MENTION], did you have Spidertrax on in these pics?

Edit...
Nvm, found the info:

P.S. Also have a dog named Tucker.... too funny!

Finally got a chance to get off the pavement and test out the Coopers. Didn't get too far out there, but did get on some decently challenging terrain to test them on. First impressions they did fantastic. Most of the terrain was loose rock and some dirt that they plowed right over. The few places I got stuck momentarily then used the terrain select and diff lock and powered right on through. Did a few water crossing that felt solid as can be, one area the depth was just up to the rocker panels. This was all at 40psi, I imagine the grip will be even that much better aired down on the Coopers.

Enjoy some pics

Looking into getting 255 as well to replace 285's. Toyo OC AT2 also come in 255/80-17 and I am wondering if anyone has experience with the Toyo's in 255. I would guess that they may be quieter on the road. Feedback?

I have them on my 4th Gen and like them. They are the LT version sidewall/tread. While I'm not the guy who rocks mud terrains just to look cool, I do wish they were a little more aggressive looking. I actually got these to replace 255/80r17 ST Maxxs that had grown loud. I loved those Coopers but hte pull to the right was maddening. The Falken AT3W now comes in 255/80R17 too if you want something that looks "cooler"

are they out yet? not showing on the falken site
 
I have no lift on stock off road wheels with no rub at all. Not at full lock going in reverse or forward. With no trimming, BMc, etc. Totally stock running 33's. Have had them fir several weeks now, and went light off-road, still with no rub.
 
Sad to see this thread died.

Anybody have specific info/pics about the Wildpeak 255/80? Considering these as I re-do the suspension and tires.
 
yeah man sad to see no more info or feedback. I love my coopers on my tacoma and now throwing a set on the wife new 2020 sr5 premium and lifting with dobinson 3/2 lift/. Anybody feel the falken or toyo 255/80/17 are better or quieter on road but still good offroad compared to coopers?
 
Cooper or Michelin?

Hello,

Newbie here. The system wouldn't let me start a new thread yet, so I'm posting here.

I bought a used 2016 4Runner SR5 earlier this year with only 21,000 miles and original Dunlops. It now has 32,000 miles and I am looking to replace the tires with either the MICHELIN LTX A/T2 or the COOPER DISCOVERER AT3 4S. I like the look and price of the Coopers, but am concerned they might not be made as well and are more likely to give me shimmying headaches.

Any advice?

Thank you.
 
It looks like no one replied to your post. It might not be the be best thread to ask the question so if you have not already received a reply in a different thread here is my input.

Ask around and see if you can catch a ride in similar/same vehicles with those tires. People tend to like certain ride characteristics so see what you like. I have run almost all brands and I seem to moving towards Coopers. I run 4-5 full size pick ups and I get a really good combination of ride, traction and durability from the Cooper AT 3 4. My next tires will most likely be Coopers on the 4runner for the same reasons for spring/summer/fall use and dedicated snow tires for winter.
 
Just got a 2021 ORP and thinking of running 255/80/17 Wildpeaks on the stock OR wheels. It is completely stock. Sounds like it might not rub but hoping others can confirm.

Thank you.
Both should be fine especially if you get load range C. I'm considering those two for my next tire as well.
 
Stock 2015 Trail w/ KDSS. 255/80 WildPeaks with a slight rub on front liner at full lock; will push back liner. Will be adding OME lift, and possibly longer bump stops if that helps from stuffing them on inclines. Thoughts?

Drives straight, steering wheel wobble is gone!
