I need to replace the tires on my truck and got some recommendations from my "all-things-trailer-related" friend. Firestone HT Transforce was among the ones he'd been told were good performers. Those fit my current budget and other requirements, so I checked reviews. I was very surprised to find reviews either 5 star "Love 'em" or 1 star "Hate 'em" with not much in between. Same thing with some Michelins. Very mystifying! I researched this further and found an explanation which at first sounded to me a little strange, but when I ran it by my friend, he said "That would explain a lot!" I then called Firestone corporate's Tech Support dept. and he confirmed that my info was absolutely correct. It'll take a paragraph to explain, but then we will all know how it works.
When a vehicle manufacturer (e.g., GMC, Ford, Dodge) makes their new lineup of trucks each year, naturally they pick tires to go onto that model. In the case of Dodge, it just so happens that they picked the Firestone TransForce. Well, this is a gigantic order, obviously, and the vehicle manufacturer can choose an existing model name (TransForce) but then get to state its own specs for this huge purchase, and that version of that model is made for them. Naturally, the vehicle manufacturer will spec their tires to favor new truck sales, optimizing things like quiet ride, smooth ride, great cornering, etc. That spec combination, however, may come at the expense of longevity (the vehicle manufacturer cares little about that, they want to sell new trucks that ride nice). This version of the TransForce tire is called the "OE version," which stands for "Original Equipment" (on those new trucks).
Meanwhile, the tire manufacturer (still in this case Firestone) continues to makes their own normal version of the TransForce tire as well, this version being to Firestone's specs. It might typically have less flex in the sidewalls (stronger for towing) but with not as cushy of a ride, might be a tad louder, but this version gets a proper amount of expected tread wear. And this version is called the "Replacement Market" version. (Those are the buzz words within the tire industry -- OE ("original equipment") vs. Replacement Market -- two versions of the same named tire. And this can be the case with any tire manufacturer (Michelin for sure is included) who's lucky enough to get one of their tires chosen for a Vehicle Manufacturer's whole line of trucks.
Do they take a hit on some bad reviews for that model of tire... for a while? Yup, they might. But eventually that straightens itself out.
So this is why the reviews on a given tire can be great (the Replacement Market buyers) and can also be bad in terms of tread wear and how quickly they had to be replaced (those who got the TransForce on their newly purchased trucks). I did notice that the bad reviews always seemed to be on Dodge trucks, bought new.
How would you know the difference when buying your own replacement truck tires? Call the manufacturer (Firestone, Michelin, Goodyear, etc.) Corporate 800 number, tech support or "other questions" menu choice, and give them your exact size tire and the exact type you are looking at (AT, HT, etc.) and ask them if that exact size and type of tire has been used as an OE tire, and if so, when was it stopped being manufactured. If it has been made in the last x amount of time (the time of manufacture you're willing to accept as shown on the DOT date code in any event) then ask if there is any telltale code numbering on either the OE version or on the Replacement Market version so you can tell them apart at the time of ordering or buying in person. And only accept the correct version. If your parameter of DOT tire manufacture date is "in the last 6 months preferably, or at least by the last 9 or 12 months" as mine would be, and that OE tire version has not been made within that time frame, you'd be getting the correct and preferable Replacement Market version tire without having to worry about it.
Also note that any given tire model might have been made as an OE tire version in only one size tire, but not in other sizes (this is the case with my tire size, it was never made as an OE tire in my size). Again, in that case you wouldn't have to worry about it.
So that's it! OE (Original Equipment tire vs. Replacement Market tire.
