33X12.5X15 Mud Terrain Tires

Might be time to dynamat the cab if you are so worried about tire noise.

Very interesting. I wonder if load rating has something to do with it. All the Duratracs I have owned are 6 ply C load rated. They also make a 10 ply E load rated version that I have no experience with.

Have had 1 set of each and the behavior, noise was about the same.
Also to be fair, both sets are/were driven primarily highway miles. Interstate driving 20-25k miles a year at 80-90mph much of it in the mountains = high speed sweeping turns daily. Which makes those tires as bad of an application for the driving I do as any mud tire would be.

Edit. The C load Duratracs on my Trailboss have 45k on them now and at least 50% tread left. But they resonate so loud in the cab at 40-50mph range you have to turn the radio up!

True but I had other requirements. I had to run an "American" brand on my GMC. I like the Toyo, I run them on my '19 Duramax but bring myself to run them on my Old School truck. The Thornbirds simply look ridiculous to me, they did not fit the "look" of a 1987 era truck.

The Coopers were a good compromise and I studied this for months before I made my purchase. I probably overthink and over research but I want this old truck to look and feel period correct.

My Nitto RGs are made in America. My coopers on previous trucks were as well. Cooper was bought out in the not too distant past and I’ve been told by someone who sells them, that the ATs can be a bit more difficult to balance. That person also said he wasn’t seeing that as much on the SttPros. I like the STT pros. I may try them on my square.

My Nitto RGs are load range F, which was a deciding factor for the truck they’re on.

Most of the tire hum/singing/noise comes from the side lugs and very few modern mud tires have side lugs sticking out past the carcass. The Buckshot Mudders and Super Swampers of my youth had large side lugs and made a LOT of noise on the road. They pulled really well in the mud, which was what we needed them to do. Noise was secondary to traction.

I am running 33x12.50-15s on my '87. The Cooper Discoverer STT PRO was my tire of choice but I was actually looking for a tire that would "sing" on the highway. I am looking for any way I can duplicate the experience of driving one of these old trucks the way I did back in the '80s. Sadly, the Coopers don't make as much noise as I wanted, they are pretty quiet so far.








We are running a set of the BFG Mud Terrains on the Bronco and they are much quieter than you would expect. Again, the side lugs don't extend past the carcass and that keeps things quiet.

If anypne really thinks today' tires are loud you should have been around for the original Denman Ground Hogs
Also I ran Regul Trail Blazers and they were loud enough to hear from far off down the road!

I remember those Reguls. They were good traction tires. Ground Hawgs were awesome too, of course... but that should go without saying

I’m willing to bet I’ve got the loudest tire on the road right now lol. I know a little off topic but had to post. Very period correct for my ‘76. Bias ply to boot.

I actually really LIKE tire noise on a truck. On a daily driver family car I want it nice and quiet and well mannered, but if I'm cruising down the road in a lifted 80s truck I want to hear throaty exhaust, humming tires, etc. It just feels right and adds to the experience IMO.

Nice input. I'm going with the General Grabber X3. With M/T tires and headers/exhaust it will be music to my ears. Win/win!

Those are the most badass looking tires. Hands down!

Nice choice!
I just did the same.
Need wheels still.

Looks Awesome! Did you shop around for them? I think the General M/T stand out from the others. When I've seen them, I always say need to check them out.

Those are the exact tires I was talking about, that my dad had on his 1 ton.

I still have the same tires, used them on the back of my dually 94.

I feel like the 86 was too “new” for the old mud grip look but I might have still done it if there were the right sizes available for the look I’m going for.

I’d been on the fence for quite a while and going 20s there’s virtually NO white letter tires made anymore.
Actually these red letter and Firestone XTs I’m pretty sure are the only non black wall 35-12.5-20s on the market.
I actually just decided to try to find them on my way to Oregon (no sales tax) one morning and found a shop that matched 4wp price and had them in stock.

What made you decide on 20s instead of a 17 or 18?
