Hey, if you’re anything like me, a recall that basically says your truck is too quick sounds more like a flex than a problem. I mean, who wouldn’t want a heavy-duty rig that can outrun what the sticker says? But the latest news on Ram pickup trucks is one of those rare cases where a little extra speed actually landed a bunch of them in the recall lane. It’s a safety thing, not a secret performance tune, and understanding why is a solid lesson in how tires, speed limiters, and heavy-duty pickups all need to get along. Let me walk you through it in plain English.
What’s Actually Being Recalled?
The National Highway Traffic Safety Administration (NHTSA) dropped a recall covering 12,736 Ram 2500 pickups from the 2023 through 2026 model years. It’s not a massive campaign—but honestly, it’s not every day you see a truck recalled for having a top speed that’s a little too enthusiastic.
Before you crack a smile and imagine a hidden Hemi overboost, let’s be clear: your 6.4-liter Hemi V8 or 6.7-liter Cummins diesel isn’t pumping out any extra ponies. The power numbers are identical to every other truck on the lot. The difference is in the powertrain control module (PCM) calibration—essentially the brain that governs how fast the truck is allowed to go. In the affected Ram pickup trucks, that electronic speed limiter was set higher than the maximum speed the factory-installed tires are built to handle. So if you kept the loud pedal pinned long enough on a closed stretch, you’d eventually outrun what those tires can safely take. That’s the safety risk in a nutshell.
When a PCM Speed Limiter Outruns the Tires
Here’s where a little insider knowledge helps. Most modern trucks use a speed limiter programmed into the PCM to cap the fun before you run into trouble. Ram, like every other truck builder, ships its 2500 series with a dizzying range of tires depending on the trim, tow package, and wheel option you ticked. One truck might leave the factory with a set of all-terrains carrying an S speed rating, good for up to 112 mph. Another might roll out on T-rated rubber that’s safe to 118 mph. The problem creeps in when a truck with an S-rated set gets the same top-speed limiter tune meant for a T-rated set.
Ram hasn’t come out and said the exact number these trucks could hit, but educated guesses point to a mismatch where some trucks could exceed the tire’s speed rating. And just because a tire is rock-solid for everyday hauling doesn’t mean it’s built to sustain triple-digit speeds for long. The faster a tire spins, the more heat builds up in the tread and the sidewall. Centrifugal force starts pulling the tread outward. Get things hot enough, and you’re looking at a sudden tire failure—even if you’ve only been pushing it for a few minutes. For a heavy-duty pickup that might be towing a loaded trailer, that’s more than a little scary.
The Tire Speed Rating Alphabet (S, T, and Beyond)
If you’ve ever glanced at the sidewall of your tires and wondered what those letters mean, here’s the quick version. Tire speed ratings start with a letter—and they’re not exactly in alphabetical order. On the low end you’ve got B (31 mph max), and it climbs through S (112 mph), T (118 mph), all the way up to W (168 mph), Y (186 mph), and Z-rated performance tires that can handle even more. Most full-size pickups come with S or T ratings from the factory because, let’s be real, a 7,000-pound truck doesn’t need to do 150 mph.
And just to clear the air: a high speed rating doesn’t magically make your truck a sports car. It just means the tire can handle that velocity without coming apart. What the Ram recall really highlights is how sensitive the relationship between the limiter calibration and the tire spec can be.

Ram’s Fix: A Simple (and Sobering) Software Tweak
So what’s the solution? Ram’s plan is about as straightforward as it gets: dealers will reflash the powertrain control module to set a lower top-speed limiter. The new number will be matched to the tires actually equipped on the truck. No parts swap, no new rubber—just a few minutes plugged in at the service bay.
Think about the alternative. Replacing all four (or six, if you’ve got a dually) tires with a higher speed rating would cost a fortune, plus the door-jamb tire information plaque would need to be swapped to stay legal. The software route is faster, free for owners, and safely clips the wings without messing with your towing capability, fuel mapping, or real-world power.
I’ll be honest, part of me would be tempted to shrug if I never planned on hitting those speeds anyway. But here’s the thing: even a quick burst on an empty back road could nudge the needle into ground the tires aren’t rated for. So I’d absolutely take the five-minute dealer visit. Peace of mind when you’re running heavy is worth a lot more than a few extra mph you’ll likely never use.
How to Check If Your Ram Pickup Truck Is Affected
Ram plans to mail owner notification letters starting June 4. But if you’re like me and don’t want to wait, you can jump on the NHTSA’s recall lookup tool or Ram’s own recall page right now—the VIN list goes live on May 14. Just punch in your 17-digit VIN, and it’ll tell you instantly if your Ram pickup truck is part of this unusual safety campaign.
While you’re at it, it’s not a bad time to glance at the speed rating on your own tires, especially if you’ve upsized or swapped rims. Keeping the tire speed rating in harmony with the truck’s electronic limits is something a lot of owners never think about until they stumble on a story like this. Now you’re ahead of the curve.
There you have it—the recall that sounds like hot-rodder bragging rights is really just a humbling reminder that even these massive Ram pickup trucks have to respect the rubber they ride on. If your 2500 is on the list, a quick trip to the dealer is all it takes, and you can get back to worrying about payload stickers and diesel prices instead of top-speed drama. Drive safe out there.
