Whatever the cause, concrete slab roads in this condition are a disaster. In the past, we had the cords break in a tire on a near new pickup truck in NorCal on I-5. The tire had large bubbles all over it. All 4 tires got replaced under warranty when we got home. On another trip on same I-5, same thing happened twice on the same trip. When it happened the 2nd time, we were extremely lucky to find a wrecking yard nearby that we limped to. They had the same wheel/tire size available and we were able to get back on the road quickly.
Many miles of Interstate were built with concrete slabs which have tended to shift with use. Often one end tips down a bit, the other up. When a heavily loaded truck tire crosses from the up end of one slab to the next, it drops and puts further downward pressure on the next. The result is a sawtooth surface. If the period of that surface coincides with the RV suspension tuning the ride can be very rough.

Add to the RVer's problem is that if you tow anything you are supposed to stay at 55. That means right lane most of the time...…. which sucks. We are going to snowbird for the first time this year and I am looking at any route besides Ca.. It will depend on the weather at first of Oct., altitudes etc.. We just returned from 2 months down to Yosemite etc. and got beat up both on 99 and I5. Not as bad North of Sac though. TB
I dont vacation in CA not even when I lived there for several reason and the speed limit is one of them

How is it that other states with heavy truck traffic are able to design roads that stand up to abuse? I assume that some truckers are over-weight, despite the scales. That is foreseeable. And I assume that it is possible to pave a road to withstand that extra pounding. But in all my travels throughout the West, there is nothing like the Calif highway system, where the right lane is just trashed.
This is not a political issue -- it has to be an engineering issue, at least in part.
The cost of this mess is not only in terms of ruined tires and suspensions. It has to result in more accidents per mile. A blowout on a big rig or an RV is dangerous to everyone.
