Less than 1/2" space between tires

I have a 2007 Cedar Creek (Silverback) 5th wheel and the tires are factory tires exactly matching what the recommended tires for unit sticker on the side of the trailer says. I think my tires are too close together. I literally have about 1/2" of space between tires. When I take weight off trailer setting up scissor jacks landing gear etc. the gap increases to about an inch or slightly more. ( trailer is not even close to overloaded ). It seems over the last few years the gap is getting closer. Would this be my leaf springs getting weak, shackles, something wearing out???? What would cause the axles to move closer together??
Thanks

All of the above would cause the gap to close. Check your shackle bolts to make sure they are not worn. Also, you should have a noticable arch to your springs, even when loaded.

Another troubleshooting recommendation: Measure the distance from hub center to hub center on both sides while setting level. If both measurements are nearly the same distance and something like 33” apart go to the next step. Find the diameter for your tires. For instance, the diameter for ST235/80R16E tires is normally 30.7” - 30.8”. If they are taller than that they may be in the first stage of tread separation. They will keep on growing until they fail completely.

Thanks guys. I'm going to bring it in and just get the shop to fix it. The leaf springs are pretty much straight flat ( no arch ) so I'm betting I'm going to be buying 4 leafs springs, bushings, shackles, maybe shocks, etc...Hope they go easy on me $$. Also this unit I'm sure to save a dollar at the factory has 5200Lbs axles!! The GVWR on this unit is 12,200Lbs+/-. 2000-2300Lbs pin weight. Wonder if it would cost about the same to just put 6 or 7,000Lbs axle under it. ( Core on 5200Lbs Axles?? )
Thanks

The 7k axles are really not that expensive. Very little difference in cost between 6 and 7. I think all the Silverbacks / Cedar Creeks are coming with the 7k Dexters now. I'd go ahead and upgrade since it's gotta be broke down anyway.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.

I'd go with the bigger hardware.

Most cities have a spring shop, google search for leaf spring rearching to find one, and give them a call. You might need a custom spring pack.

Weight police admonishing you for being overloaded in 3...2...1...
