Keystone Cougar Tires?

friz · 01-15-2019, 08:31 AM

I have a 2004 Cougar 278EFS 5th wheel. Loaded (gross?) weight around 8100 lbs. I bought the unit last fall. The tires that came on it are 205 75R 15 load range D. Some oddball brand which I don't recall at the moment. I was reading a forum post that Sailun tires are the go to brand. So I went to their web site but did not find a trailer tire in that size. Got me thinking that maybe my installed tired are not the right ones. Haven't found the manufacturers recommended size. Can anyone help me here?

Thanks, Friz

Friz, I ran down that model at General RV and it seems that the tire size is indeed 205 75R R15. Might I suggest a trip to WalMart for set of Carlisles, in the neighborhood of $65-70 each?

Thanks for the assist. Also have learned the trailer originally came with Load Range C tires. I have D. Pretty good price on Carlisles at Wal Mart, $65.27 out the door.

It's always recommended to change valve stems with every tire replacement. For RV trailers steel ones are best, especially if you plan on adding a TPMS sometime in the future.

Whatever you decide, make sure the valve stems have the required pressure rating for your replacement tires.

Good idea about the valve stems. What are your opinions about Maxxis tires? I believe they are normally priced around the Goodyear Endurance. Amazon has them priced at $86 delivered. Maxxis M0008 ST205 75R 15D speed range R (106 mph). If I drive at 60 mph what affect or advantage is having a tire with that high of a speed range?

If that speed rating is not displayed on the individual tire sidewall it's a 65 MPH tire.

The importance of having speed ratings on ST tires is their link to load capacity. Very basically, it means a tire rated at 75 MPH can carry its maximum load capacity up to that constant speed. Above that, the tire degrades more rapidly as the speed goes up.

Any one have some input on the 14 ply tire called provider by taskmaster that etrailer sells. I'm between these and good year endurance 10 ply

That's old terminology. They use load range ratings such as E, D, etc. Tires are now rated by pressure. The higher lettering the more pressure they can hold. Higher pressure means higher load.

Tires are the one thing I would not go cheap on. IMHO, buy the best tire and always upgrade to a higher rating. The trailer manufacturers give you the bare minimum rating. My trailer has 205/75-15 and I run load range E at 80 psi. My tires are Maxxis M0008 ST205 75R 15E. Next time I might go with Goodyear's. They are having good reviews at other sites such at the Keystone forum, etc. Beyond load range D, 65psi you need to upgrade to metal core valve stems. The rubber ones are rated to 65psi.
Don't go cheap!

End of my story. Just delivered to the homestead a set of Maxxis ST205 75R 15D, date code 2618, 6 year manufacturers warranty from date of manufacture, $85 each, delivered. Looking forward to seeing you down the road (not on side of the road).

Will never know, but think you are much better off with Maxxis than the Taskmasters...

When you upgrade your tires to one that has a higher pressure, be sure your rims are rated for the higher pressure.

And the valve stems.

Never did wrap this up. Settled on Maxxis 205 75 R15 D. Got them for $86 apiece delivered. Company out of NC advertising on Amazon. Only con is not speed rated so that means 65mph. Not an issue for me in my 7th decade.
