Talking New Tires - Cooper STT Pro - Pics Inside

Hey Everyone. Finally replaced the tires on my 2010 F150 FX4 SuperCrew. Just to bring everyone up to speed on my setup both before and after:

Before:
Nitto Trail Grappler - 295/60/20 - 70,000 miles on them!
XD Monster 20x9
Bilstein 5100's leveled up front and normal in rear

After:
Cooper STT Pro - 35x12.50x20
Same wheels and suspension mods

The STT Pro actually comes in the same 295/60/20, but I was able to go with the 35's because of the actual specs. The 295 for the Nittos is pretty large for that metric sizing and the 35's for the Coopers is a bit undersized, so they came out very close.

LT295/60R20 34.45 12.13 8.5" rim (I have a 9" so pushes it out a bit more)

35X12.50R20LT 34.69 12.4 10 " rim (I have a 9" so brings it in a bit more)

Now that I see these measurements again, I see why to my eye, the Cooper actually doesn't look as wide as the Nitto. With the rim widths taken into account, the Nittos would probably be little wider.

But anyway, obviously I had great success with the Nittos and most probably wonder why after 70k I'd even consider doing something else. But I like trying new things and the Coopers are cheaper. Wasn't sure I'd have the truck for another 70k miles (already at 105k), so that wasn't a deal breaker.

My initial assessment was that it was quite a different look for sure. Not using that fairly standard symmetrical looking tread pattern. With that, just like when I started using Mud Terrain tires for the first time, have to get used to how those big lugs "move" the vehicle while driving. I feel these a little more initially, but I've gotten very comfortable with it. They may be a tad softer feeling, but I don't know if thats just because they're new and have lots more tread on them. The sound is interesting. I hear it, but its a different sound and I almost tune it out better than the sound of the Trails. Especially at highway speeds. So far I like them. I do miss the "width" look of the Trails, but overall I'm happy.

Here are some pics. I posted both the old (when they were new) and the new so you could see the differences. Let me know what you think and if you have any questions.

I have almost the same setup with the 295/60/20 Trail graps, and the 20x9 +18 offset. I've been looking at selling my nitto's and trying the mastercraft mxts in the 35/12.50/20, nothing wrong with the nitto's but the masters are almost 10lbs lighter per tire and a fair amount cheaper, but now looking at how good the coopers look I'll be doing a little more thinking. Truck looks awesome by the way!

Thanks! And yeah, these are lighter as well and cheaper. I'm happy.

Thanks! I've had them for a little bit now and I'm happy with the way they handle and sound. Happy with the look too of course. Haha.

You were right about not looking as wide, I just put on 35x12.50x20's also and they seem to fit slightly better then the 295's did.

Yep, agree. Definitely a hair thinner.

Just wanted to revive this thread with some closure. Swapped out these Coopers today. Went with the Nitto Ridge Grapplers as a replacement. I'll start a thread with those specs. But I just wanted to provide a final review of the Coopers. I took them off at 47,000 miles. You can see from the pictures that tread depth was still fine. I had one bent rim that may have caused some uneven wear, but they had become annoyingly loud. And slow speed manners weren't very good. Until I drove with the Ridge Grapplers (admittedly not as aggressive), I didn't realize just how loud the Coopers had gotten. All in all the Coopers were a pretty good tire. They had lost some of their road manners as they wore for sure. I do think they looked pretty sharp. I may have pushed the sizing a bit. I was getting a little scrubbing on the back of the wheel well. Could be attributed to suspension softening over time. But I'd say the Nitto Trail Grapplers held up better over time. Less variation as they wore. Let me know if you have any wrap up questions. Heres a pic of one of the tires at 47,000 miles.
