Question:

Hi Glen!

We do have a few 16" tire/wheel options available that have the 6 on 5.5" bolt pattern you are looking for, but they are a lot less common than the 8 on 6.5" bolt pattern. Which is why you were having trouble finding them.

So with that said, I recommend the Taskmaster Rambler ST235/80R16 Radial Trailer Tire w/ 16" Vesper White Mod Wheel - 6 on 5-1/2 - LR E # TA48GR. This has a 3,520 pound capacity at 80 psi and an M speed rating (81 mph), so it will make a great spare.

Do you have a spare tire mount on your 2015 Keystone Cougar? We have a bunch of options if you don't.
