Upgrade Tires
Purchased a 2013 Outback 250RS last December. Still has the original tires on it. I know I've read here many times before to not trust the original tires very long. Over the course of the summer, th...

Let me see if I understand this correctly .
Jim is worried about a wheel failure due to increasing the psi to 80 .
There are no threads about wheel failures due to too much pressure .
However , there is a thread every week about ST tire failures .
To argue that there is no benefit to using a tire that has an 80 psi rating over a tire that has an 50 psi rating does not make sense .
The 80 psi tire has a 2830 pound rating , and the 50 psi tire has a 2150 pound rating . Same size but a 131 % load capacity of the load range C tire .
If you ask CapriRacer and the other knowledgeable folks they will tell you that the higher psi tire at max sidewall pressure is the way to go .
Plus there have not been any steel RV wheel failures reported on this forum.
I had an aluminum wheel fail me once .
What happened was that it developed a hairline crack ( not visible ) and the wheel simply failed to hold air pressure .
I noticed the tire going flat in plenty of time to go to the tire shop and get it replaced .
It was not explosive or life threatening .
So lets be safe out there .
That means upgrading your tires ( the weakest link ) when you go to replace them .
The experts recommend an upgrade in Load range ( C to D , etc .) first because the original steel RV wheels can be used and there is no problem regarding clearance issues .
If you have had a steel wheel fail you in a dangerous way then speak up , please .
