I've got a 2014 and will check this out tomorrow as I am getting ready to head out for another trip and happen to have it sitting in my driveway. This will give you a good comparison. I am pretty good about checking my tires every time and haven't noticed anything with mine yet. Got about 3500 miles on them right now with no problems as of yet. I'll try and take some pics as well.

OK, So i talked to the warranty guys with Forest River and they were great help and sent me new springs right away. I actually received them this afternoon!!
Here comes where good goes to really F-in Bad. So the mechanic is under the trailer taking a look and he calls me over and tells me the frame is bent....... So i crawled under and took a look...... YUP its BENT! it actually buldges in right about in between the two tires... Well this probably explains why the slide is acting up. still not sure why the leaf springs are flat as well.... I guess thats it for camping this summer!
I am not sure how this is going to play out with the warranty but i dont have any idea how or if you even can fix it, and to be honest i dont even want the cured thing anymore... SOOOOO FRUSTRATED AND DONE WITH THIS THING.
