No good tires

Just got home from a short trip to sun lakes in eastern WA. Before we left I checked all tire pressures set at 80 psi. Just before Quincy WA hurd loud boom looked in left mirror to see big piece of side skirting dragging on the road and flat tire. lucky the rest area less than 1/4 mile up the road was able to limp in and put on the spare tire and remove all stuff hanging down dragging. Now buying Sailuns for all 5. Insurance will cover the repairs but have to be without the trailer probably the rest of the summer. Ordered TST 507 tire pressure monitor before we left but didn't show up until 2 days after we left.

You were pulling a 3820FK with 80 PSI in the trailer tires? Are your tire E or G? I would think a 40' trailer should have G rated tires with a PSI of 110 not 80.

RoadRunner,
Don't be too hard on DanandBrenda.
In 2015-16 (and many other years) the factory was sending out these heavy rigs with 'E' rated tires @ 80 psi.
That is what is listed on the sticker, too...
Some of us just have to be convinced at how scary this is.

DanandBrenda,
I feel your pain. We were convinced...
Last year, on the way to the Fall Rally, on the interstate, no rest area near by, steel railings 10 ft off the roadway, and semis rushing by in the near lane. Just lucky the blown tire was on passenger side.
Had to buy a pair of tires at the next stop just to make it to the Rally.

You have made a good choice with the TPMS, now invest in a set of 'G' rated tires. The wheels on your rig should be rated for 110# so you're halfway there.
I can recommend Sailun 637s. A quality tire that is value priced.

Yes E rated tires is what came on it new. the new tires will be G rated 110 psi.

Tires are always a hot topic in the summer.
If you have the standard ST China Bomb tires on your camper get them off before this happens to you.

My 3582RL cam with E rated tires. Drove them a whole 7 I think miles to a Discount tire store and replaced them.
Employees at the tire store thought I was crazy to be replacing new tires.

Just now replace that set with Sailun’s.

Just a note to reinforce your LRG choice; under the new RIVA recommended standards for your axles, replacement tires should have a minimum load capacity of 3850# ea.. The Sailun ST235/80R16 LRG provides 4080# of load capacity at 110 PSI and that designated size is your best choice no matter what brand you use.

Just remember to check your wheels max PSI rating, which is stamped on the back side of the wheel. Not all wheels (rims) are created equal! A reputable tire store would check the wheel to make sure that the wheel's rating matches the tire rating before mounting or selling them to you.

Yep, LR E cheapies are what came with my '16 3711FL. These big FWs need LR G at 110psi. Also, make sure the wheels are rated for 110psi.

WHY doesn't anyone seem to understand that, yes the E or G rating is important, BUT check your DOT 'born on' date stamps and write them down! There are tons of information by all the tire manufacturers about how tires will degrade over time no matter if their covered or indoors. Nothing but semi trailer tires will be safe with a close to rated load after five or six years.

I always check the "born on" date of my tires. Much like I check the age of DEF.

Buy 14 ply tires They handle the weight better . Stay under 65 mph in hot weather. Trailer tires are not rated for 65mph.

TPMS does not protect against bad tires. Best to buy LT tires.

Check out the "Dry" empty weight of your selected Tires. Tire Rack.com, etc.
I only run Michelin XPS Rib and Bridgestone Duravis R 250 LT tires now.
The heaviest (more rubber) AND most expensive LT tires.
I've also found they very seldom need to be aired up unlike cheaper tires I've had in the past that frequently were down a few pounds every few months.
I've had one Flat due to a nail, and lost one wheel (with the tire) due to some bearing failure. Replacing is expensive, but at least I can't blame the Tires.
My old Big Sky has 6K axles, 80 PSI rims, and weighs just under 14K lbs.

On my new Monty, the tires were set at 80 from the factory, but the recommended pressure on the tire side wall said 95. Checked with dealer and boosted them up to 95 psi. My last trip was about 7,000 miles - no problem.
