Yes the KDW(2) is not the OEM or stock replacement tire.
Right now the ONLY tire that can replace the stock rears in their identical size is the OEM KDWS from BFG. No one up to this point makes a 245-55-18 tire aside from BFG in the KDWS.
The KDW(2) tire at 255-55-18 is a popular alternative as this size is close to our original tire diameter.
The sad part is that there will not be any other KDW(2) sizes that will work appropriately on the rear since the 255-55-18 is discontinued.
This is sad because the KDW(2) holds the following characteristics compared to the KDWS OEM tire:
- Better traction in dry and wet
- Doesn't turn brown and look like a round turd on your rim
- Appears to exhibit better treadwear characteristics
- Has the neat tread pattern which some like (some may not)
All in all I feel it's a superior tire unless you want:
- To keep with the OEM solution
- Need all season performance
- A sub-par tire (yes I said it)
I'm not saying the KDWS is a bad choice, in fact when they're in stock it's probably the most cost effective choice compared to other options. But at the same time, I think you don't have to look to far to find a superior tire that will work, the HARDEST part is getting all-season performance in another solution - for that it's still only KDWS.
I do not believe BFG will discontinue the Marauder KDWS rear tire anytime soon. They know very well that they make the only tire in this size and may have a committment to make these for a number of years from Ford. (Actually that I would be curious about.)
A year ago when they were scarce I think the main reason was the age of the Marauder mixed in with the poor wear characteristics of that tire, most of the Marauders on the road had probably shed their rear tire skin and there was a run on demand.
They upped production, people found other solutions that worked better, and many have learned how to coax more treadlife from the KDWS with different air pressures, so right now they're in stock.
The good news in all this is that there are other options in the 255-55-18 size but many did like the KDW(2) in this size.
