Help me find the right tires for my 2008 X189FD
Hi all - time to replace the tires on our trailer. They're 205/75R14 so that gets me started. When we tow we're usually a bit slower to reduce the fuel cost, but have been known to cruise at 120 km/h so I'll want a speed rating of at least L.
It gets trickier after that, though. For the load rating it says to either consult your owner's manual (which doesn't seem to include specific information for my trailer) or purchase according to the tires currently on the trailer (which is great, if the last owner put on the right kind). It's a light trailer (2660 lbs dry) and dual axle, so a wild guess would be that I'd maybe estimate 3500 lbs max loaded up, divide by 2 since it's dual axle and so require a load index of at least 99 (for 1709 pounds)?
And I can choose between 6 and 8 plies, but I'm not sure which is better. From what I can see, if a 6-ply will provide the load ratings I need it will actually wear better and ride more smoothly... more plies makes for a stiffer sidewall to handle more weight but also a rougher ride.
We only use it in the summer and don't tend to put on tons of distance, so I expect that whatever tires I choose will likely age out before their tread is gone. And we're not doing back-country or off-road... the roughest terrain we usually encounter is between the campground entrance and the spot.
So, based on all of this, if I'm looking for 205/75R14 with speed rating of L+, load index of 99+, 6-ply ideal (but 8-ply still acceptable), I get a range of prices per tire from $95 (all prices in CAD) for a DurableMax RS03 (load index 100/96, speed rating M, 6-ply) to double that... $186 for Goodyear Endurance (load index 105, speed rating N, 8-ply).
That's assuming I should stick to ST (special trailer) tires. I can get the size I need in regular, non-trailer tires, too, which adds 4-ply to the equation.
I have no doubt that the Goodyears will be better than the DurableMax, but either will be susceptible to a nail on the highway and will eventually age and need to be replaced, so are the Goodyears $400 better? Or do I go for a Carlisle somewhere in the middle?
