Cooper discovery sst, ko2, duratrac

I am thinking of buying new tires and I'm down to these three.

I love the look the to copper tires and a lot of great reviews and some bad. I live in nj and we do get snow I heard they r not the best in that department. (I don't think any tire is really made for snow I could be wrong). Not sure what the mileage rating is either I read some saying 30k and some closure to 50?

Ko2 love the price point not to sure if I like the look of the tire as much. Read good thinks about this tire on the jeep.

Duratrac I read very mixed reviews on this as well. I like the look but I don't like the price point. Dd 90 percent of the time about 30 miles a day give or take in the jeep. I plan on going more off raiding this year.

Size would be 285/70/17

Sorry if this read was done already. I have a hard time finding threads on the iPhone

Thanks for the help.

I got the cooper discoverer st maxx's in size 295/70 and love them. They ride really smooth, not noisy at all and are great on road and off. I just got them about 10k ago and there holding up great. I was going to get duratracs but they were out of stock but Im glad I found the discoverers, they are a lot cheaper too. The coopers are also an a/t and have a really aggressive look I would deff get over the ko2s

The S/T Maxx is an all terrain like the KO2 and Duratrac... The STT Pro is a mud terrain tire and will be noisier on the street and have less wet weather capability.

The S/T Maxx, KO2, Duratrac and even the Kelly Safari TSR and Mickey Thompson ATZp3 are very good tires for a DD Wrangler.

I run S/T Maxx and it is an exceptional tire.

We have 33 x 12.50 x 15 Duratracs on a 2013 JKU with about 48 K miles on them and frankly Im upset because they wont wear out so I can buy another set.

We have Cooper STT Pro's in 35 x 12.50 x 15s on a 2015 Rubicon with 10 K miles on them. They are slightly louder than the Duratracs, ride about the same and whoever says they do not do well on wet pavement quite frankly does not know what they are talking about. They are great, and ten K miles do not even appear to have made a mark.

I rotate both sets every 5 K miles. and run both at about 27-29 PSI Took some experimenting with the Pro's to find the sweet spot with pressure. These 35 x 15s seem to like 27 on the Highway. Make a killer footprint at 12 offroad, and produce the best traction I personally have ever experienced.

Had to have them balanced twice but it was not the tires fault. Either tire I would gladly purchase again.

The JKUR has a RK 3.5" lift and the JKU has a TF 2.5. Both have Rancho 9000 shocks. Both handle and ride way better than they did with OEM tires and suspension.

I love the way the pros look just worried about wear rain and snow. Plus I'm a 90 percent Dd.

I think my problem is I read to much info and get myself confused on what to get. I guess that's a good thing and a bad. I should just pull the trigger and take a chance with the stt pro.

My wife has been on these tires through one of the wettest falls on record around here. No issues whatsoever, nor have I when she lets me drive it.

I would bet money on you loving these tires.

I had issues at full stuff eating the front and rear bumpers with these 35s and an RK x factor. Since we installed Poison Spyders front and rear we have great clearance. Will post you a before and after when my wife gets home, those bumpers have been on for over a month and still haven't taken any pics of the new bumpers. These are before bumpers pics but it does show you the tires.

I have the Cooper STT on my TJ. NOT the STT PRO. Idk if there are differences or not. Kick ass mud terrain, rather noisy, and absolutely awful in the rain. I hit my brakes but you wouldn't know it cause the jeep skates like it's on ice. Sketchy as hell. But dang these tires are tougher than anything! I wouldn't go with any other tire for the trail, for the road I'm kinda worried it's going to get me killed in the rain. Probably going to try a different cooper tire for my next switch since I still like driving my jeep on the road these days.

You're good... None of the M/T's will have "all" of the traction that an A/T has in the wet, but the Coopers are the most advanced design M/T on the market today and will perform excellent for you, quite close to an A/T actually.

And, just sent you photo's of my S/T Maxx's.

Thanks ur ride looks sweet I'm sticking with 285/70/17 I was originally going to lift but I do not have the funds to do it correctly with re gearing and other stuff. I must have read reviews on an older version on the tire saying it wasn't good in the rain. After seeing the pictures of urs I have to now decide on which one to get the pro or the maxx. Loving the look for the pro Walmart here won't instal them because they r not stock size so I will need to find a tire shop that has the tire and will install them.

Thanks

we are getting a lot of snow here so I have been giving my KO2's a work out. these things stick like studs on ice and snow covered ice and same in the rain (not like studs ) but do not slip. Anybody who drives in winter conditions needs to consider these. I am at about 8000 miles on them and they will last 50000 based on the lack of wear so far.

"Kelly Safari TSR "

I had in excess of 65,000 on mine and tread still measured 11/32s!!!

Great on all surfaces I encountered. Not noisy on pavement. Never got into really heavy mud, unknown for that.

Biggest complaint was the tread liked to pick up the 3/4" minus gravel from the driveway & fling it out at road speed...or worse...NOT fling it out & clickyclick until you dug it out with certain annoyance.

Certainly I'd buy them again.

I've run my STT Pro's for just about 9K miles. You will not have an issue with traction in the rain.
Of course, we have not had any snow to try them out on but when it comes to rocks, mud, clay, wet roads these tires get it done.

Forgot to add, I bought the coopers from tread depot for 175 per tire. They were 33x12.5x15. Best price I was able to find anywhere and they shipped to my door! Good luck man, let us know how they do in the rain. I'm curious, maybe they are much better now.

I'm really liking the K02s I recently bought. Very quiet and handle very well in the rain. I was between the Duratracs and these, and bought the K02 because it is a true truck tire, the Duratrac was a passenger car tire, at least in the size I bought. Tougher sidewalls was important to me. I can't wait to have these in the snow, but it's fricken 73 here today. WTF?

Good decision, don't change your mind. Count me as one more person saying you'll love the STT Pros even on the road. They are siped, so that helps. Just drove today in a downpour and it's already been pretty wet here. Great traction, no problems whatsoever.

no idea on your rub
I had no lift/OEM rims/275/65R18 was the biggest I could go without changing stuff. Had to adj bumpstop steering about 1/4 turn and got 'just a touch at full R/L wheel lock'.

Love the S/T Maxx. Had on my silver(295/70R17) and just ordered my 295/70R18 for my new Jeep. They rode great and were quiet. I hope they ride as well in the 18" version.

I cannot seem to send pictures through a PM so I will just have to stick them here. I told Hcsif720 I would show him the clearance after bumper change. These tires are the bomb. Been so busy deer hunting and work I slapped the bumpers and winch on and never took a pic till this afternoon when My honey got home from work.
