Problem is most RV rims are rated at 50 lbs. Check your wheel PSI rating before over inflating. Note: many Aluminum wheels are rated higher.

Sorry, I missed that. But, I can say that my tires were 80 psi and rims rated to 110 psi.

(And, either way- I think this is off-topic for the thread at hand.)

I routinely tow at exactly 68mph. and when conditions are present, I have no problem running 70mph.

55mph can be just as dangerous to the right driver!

2014 ram 2500 diesel crew SB.
Only 2100 lbs payload.

My factory stock 16" Maxxis Rated E specify 80psi for max load and speed is max at 65mph.

You will have to explain that one to this dumb hillbilly.

There's a report (From the 60's, but it's still valid.) showing that a vehicle going 15mph slower than traffic is more dangerous than that same vehicle going 15mph faster than traffic.

The theory is that in the example of the vehicle going faster than traffic, it's only one vehicle weaving through traffic, they expect to catch traffic and are prepared to deal with it.

But when one vehicle is going 15mph slower then they become a rolling road block, traffic is now weaving around the slower vehicle, other drivers aren't going to expect that speed differential and may not adequately prepare for it. Sudden hard braking and/or lane changes by those unprepared drivers exacerbate the situation.

It's part of why 45mph minimum speeds were established, but they were also set when 55 was the law. What was 10 under is now 25 under in many areas.

Can understand it with regular vehicles, but not with an rv which is much larger and easier to see and most folks are very much aware that they don't travel at high speeds. When I see one if I'm not towing, I get over in another lane at least a 1/2 to 1 mile before I get to them. Same with semi's. I also steer clear of rvs going 70 mph knowing they are susceptible to erratic things happening to them at that rate of speed.

I had the same tires. There was a forum member here who owns a tire shop. He put a dealer inquiry in with Maxxis and they gave guidance that if the tires have a margin in load carrying capacity (ie, they aren't maxed out) that you can increase the speed whilst also losing carrying capacity. It was complex, but basically- if you have extra carrying capacity on the tires, you could go up to 75mph on them.

I'm not proposing or even advocating for going faster- I'm just saying that the standard line of "ST tires are only rated for 65mph" isn't wholly accurate.

UNSAFE how? You caveat it as "on ST tires"-- so, if I put LT tires on my rig, is it safe then? What about commercial trailer tires?
