Tires

SIL and I have a question. Men are away so can't ask them and SIL wants to deal with this herself.

The tires on our brothers and SIL TT are wearing funny.
They have about 1500 kilometres on them about 932 miles.

The tires on the passenger side are wearing almost smooth on the inside. I will try to explain. The tires have four or five rows of traction and the inside row is practically smooth.

Is something out of alignment? I told SIL not to take TT anywhere until they are checked properly.

    Yep, the trick is going to be finding a shop in your area that knows what they're doing.

    The "worn parts" issue should only occur if you've used the trailer a fair amount. Shouldn't be a problem if it's almost new.

    The "alignment" issue can happen if you hit the curb or a pothole hard. But since both axles have the problem, this may be less likely.

    The "overloading" issue means that the axles/springs may not be heavy duty enough for your trailer and what you put into it. This is quite common and some have had their axles/springs upgraded under warranty.

    There should be a label on the trailer giving the axle's GAWR (Gross Axle Weight Rating) and trailer's GVWR (Gross Vehicle Weight Rating). With a double axle trailer you want twice the GAWR to be comfortably larger than the GVWR. Mine is about 25% larger but I've seen some where twice the GAWR is actually less than the GVWR.

    Good luck.

    Too much air for the load can make the center of the tire pooch out (commonly called "crowning"), reducing the contact patch of the tire to the center few rows of tread.

    According to your picture here the wear would be on the far left of tire.

    If the tire is on the vehicle it would be the 2 passenger tires with the wear on the far left side. Not the middle as shown on your pic.
