NEW Shoes for MOBY : 40x13.50R17 Cooper Discoverer STT Pro M/T Tires
- Thread starter wayoflife
- Start date
Welcome to Wayalife. Stop by the Give us a wave section and introduce yourself. I'm from outside of Lafayette so I'm interesting in getting to know you.
You bet! I'm eager to see how they compare to other 40" MT's I've run in the past.
Yes, Toyos are heavy tires but trust me, not as much as so many seem to think. But, like you, I am interested in seeing what the actual size and weight difference is. I'll be sure to post up what I find when I can.
Well, if I can break down what I have and can get these new tires mounted by the end of the weekend, I will for sure get out on the rocks to test them out next week. :yup:
Toyos are great tires and as many know, they are what we've preferred running on Moby for quite some time. I don't think you'll be disappointed. From experience, I have found that the Cooper STT Pros hook up better on the trail but are slightly louder on pavement. Where they really tip the scales is in their price. What I have found is that you can get 5 Coopers for the price of 4 Toyos or Nittos and at least back when I needed a set of 37's for Rubicat, they were actually available whereas my other choices were not.
LOL!! Hadn't even thought about it but yeah, I suppose they will be :crazyeyes:
As of now, the 40's are only available in a 13.50 and for a 17" wheel. For my purposes, that's what I wanted and prefer. Anything wider on full width axles is too wide - at least, based on my experience.
No, there is no information about them anywhere yet but yes, they are officially available now. You need to have your tire shop call and order them for you.

As for road noise, how would u rate them relative to Rubicon stock rubber, if u can?

Personally I don't find them loud at all. I had General Grabbers on the Jeep before these and they are no louder than those.

Thanks! I'm excited to hear your thoughts on the onroad comfort comparing the 37 and 40" versions on Moby and Rubicat. I'd almost think Moby would be more comfortable on the road with the 40" since it's a C and has more rubber.

Those tires are freaking sweet. In a few years when my nittos are toast, stt pros will be my next choice in 37's.

They're HERE!! :wings:
As some of you may know, Cindy and I have been running 37x13.50R17 Cooper Discoverer STT Pro M/T tires on our 2012 Jeep JK Wrangler, also known as Rubicat and a much smaller 225/75R16 version of it on Renny, our 2015 Jeep Renegade and we've been so impressed with how well they perform, we've literally been chomping at the bit to get them in a size 40 for Moby. Well, I'm happy to announce that Cooper Tire is finally making these awesome tires in a 40x13.50R17 and we just got a complete set of 5 of them in today. Needless to say, you know what we'll be working this weekend.
For those of you who aren't aware of it, the Cooper Discoverer STT Pro is a replacement of its predecessor which was just called the STT. According to Cooper, this new tire is their most advanced and extreme to date and in addition to it's new and more original tread design that features an aggressive "3-2 center rib design" and shoulder lugs they call "side-biters", the new STT Pro comes with an all new "silica tread compound" and improved sidewall strength through heir "3-Ply Armor-Tek3. I should note that unlike the 37x13.50R17's which come in an Load Range E, these new 40x13.50R17's come in a softer Load Range C and that means they will offer a softer ride. Of course, what we love most about Cooper Tires is that they're made right here in the U.S.A.
With all that said, here are some shots of what we just got. Drool away :drool: :crazyeyes:
I'll be interested to see how they air down...I have Toyo's OC MT's on the Brute and the sidewalls are pretty stiff...almost need to get into single digits to get a decent bulge...
LOL!! Moby's tires are well used but far from bald. The shoulders are worn from trail use for sure but I think we have about 20k on them and down the middle, they still look great.
Without question, Range C 40x13.50/R17 Toyos are a hell of a lot more comfortable than Range E 37x13.50/R17's. The 37" Cooper STT Pros that we're running on Rubicat are surprisingly comfortable for being a Range E tire and I would assume that the Range C 40's will be even more so.
Yeah, that's typical of Toyos. I get people telling me all the time on YouTube that I need to air down. Little do they know that I typically run about 8 psi on the trail. If it's a really hard trail, I'll go down to 4 psi and have actually run 0 psi a couple of times without knowing it at the time. By comparison, if I air down the 37x13.50 Cooper STT Pros we have on Rubicat to just 15 psi, they "look" more like they're sitting at 10 psi or lower and this is in spite of the fact that they are a Range E tire.

Okay, finally found some time this afternoon to rack up Moby and work on breaking down tires.
Gotta remember to remove the valve stems before working on the rings.
Now for the fun part - spending the better part of an hour removing a gazillion bolts :crazyeyes:
Only thing that sucks is that all the tire shop close early on Saturday and so now we're in a holding pattern. Hopefully we can find something open on Sunday otherwise, I might have to dismount the tires from the wheels the old fashion way :icon_crazy:

As many tires as you seem to go through, just buy some more rims. Unless you're planning on selling your toyos.

Oh, just for kicks and giggles, Cindy and I took a few measurements and weighed a few things. For your entertainment, I think you'd be interested to know that a brand new 40x13.50/R17 Cooper Discoverer STT Pro unmounted weighs 91.5 lbs., has an actual footprint that measures about 11-5/16" and a tread depth of about 11/16".
Here you can see how we measured across the widest point of the tread footprint.
As you can see here, edge to edge, the actual tread footprint measures 11-5/16".
And here you can see that the tread depth is an impressive 11/16" deep.
By contrast, a brand new 40x13.50/R17 Toyo Open Country M/T has a tread footprint that only measures about 10-3/8".
And, the Toyo only has a tread depth of about 5/8".
I should note that mounted and fully inflated, the widest point on the 40x13.50R17 Toyo Open Country M/T is a true 13.50" wide. Likewise, on our mounted and inflated 37x13.50/R17 Cooper Discoverer STT Pros that we have on Rubicat, the widest point on them is a true 13.50" as well. I can only assume for now that the same will be true of the 40x13.50/R17 Cooper.

Ummm, if I'm lucky, nothing. Otherwise, tape on weights from a tire shop? :idontknow:

I hear you can throw in like 5 pounds of balancing bead.... er BBs and that'll make a cool sounds when you drive, slow and accelerate. Almost like having a playing card in the spokes of your bike back in the day!:rock:
LOL!!! [emoji23].......
