Looked on the tire and manufacture date was May 2015

Tires ..... -- ...gotta be properly inflated to support the actual weight which ya don't know without a scale. I think it's under $20 at a CAT scale......

I paid $11.50 @ Fly J/Pilot north of Richmond while returning from Delaware. Weighed Fury with full fuel, water, & normal RV trip cargo on board. I recommend going in to desk & telling a specialist @ desk what you want to do. That person will set up a ticket for you & recognize you when you call in over the intercom at the scale.

You can get a no cost 2nd weighting within 24 hrs. That is for truckers to learn the payload's weight. 2nd weighting can be useful if you change load or hookup a trailer.

Escapees RV club offers a service where they weigh each wheel's load. CAT scales only provide axle weight.

Some thoughts on these terrible blowouts.

The Interstates have rough road surfaces + frequently there are debris or obstacles on the road. My son hit an unavoidable large piece of steel & it destroyed the right front & rear tires on his new pickup. Repeated impacts at high speed can delaminate the belts & plies of the tires leading to blowouts. Hot weather & high speed running add stress to tires, engine cooling, and batteries.

I never cease to be amazed by how many RV problems are solved by new tires & new batteries.

When a driver learns the vehicle, an overall knowlege can develop as to how many bad bangs, pothole impacts, hard braking, & puncture repairs the tires have had. If one starts being worried about a set of tires...then "retire" them.😊 Get new tires when you want them.

I'm going to replace Fury's tires next year although they will be only 5 years old. The techs @ McGriff truck tires inspect Fury's tires each year. In May, Chris said look like new, no dry cracking or checkering. I usually run Fury @ 60mph & 1200 rpm or 64mph & 1300rpm. Why add the stress of high speed in hot wx?

My opinion is that American industry has seriously let down vehicle owners. Air inflated tires are nothing but danger & trouble. The tires are too weak, prone to failure, need constant service & maintenance, plus have very short life. My Coach House Type B RV has needed 8 sets of new tires in only 22 years. As soon as we learn how to produce anti- gravity with electricity, rubber tires will go away like Polaroid cameras & I won't miss them

RV was weighed last year while we it was in for repairs at Dynamax. We made it a trip, so the RV was loaded for a long trip. We were 350 pounds over weight in the front. Dynamax added new heavier springs from 7,000 Lbs to 7,250 Lbs. we unloaded the some stuff on the front of the cab to lower the weight to what we are supposed to be.

I’m guessing the age of the tires is what got you. I go 4 years if it gets driven a lot. 3 years if it sits for long periods of time. I just replaced mine last week. Tires looked good and still had plenty of tread. My Chassis is a 2016 and coach is 2017. It will be 2 years in August since I purchased it new. It has 34,000 miles on it as of today. Leaving on a 4000 mile round trip next Tuesday. Better safe than sorry with as hot as it is this summer. I hated to spend the money but why risk it. The cost if one blows is much much more and you still have to buy tires.

In my opinion, the 5 series should have nothing built any larger than the 30FW, the 36DS and my 35DB should have never been built because of the limited weight capacities. Let's face it, why have 7 seat belts in mine, and all the tanks/storage areas if we can't load anything more than grandma and a tank of fuel. I was on that same interstate in and out of Nashville, sorry about your bad luck.

Bad luck got worse today when headed to Amarillo, TX and one of my back tires tread came right off. The roadside tire guy could not understand why that tire peeled its tread. He said those tires should have been able to get 7 years out of and he could not see any signs of rot on them. Are plan was to change out the rest of the tires when we got back home, but now going to wait it out in Amarillo tomorrow and hopefully get brand new tires all around.

The CCC already includes a full tank of fuel...so that would not factor in.

A 36DS and 35DS on 4x2, come in around 1600 lbs of CCC. We build what people want...but we cannot force a customer to buy what they need.

If someone wants ZERO restrictions on carrying capacity, then they should buy a Force HD. That will likely have about 8,000 lbs of CCC. Most people do the research and buy what they need. However a small group, buy, based on what they can afford and that's when things get dicey.

If your budget is an Isata 5, but you have a family of 7 and want to dry camp, then a used Force might be their best bet.

We had someone that was dead set on a Force HD and that was the right coach for their family. But then they saw the Isata 5 (more in the budget)...and that would likely have worked too. But then they went and bought an Isata 4 and did nothing but complain about CCC???

Just a tidbit to anyone shopping. I don't hide this stuff. There is a YELLOW sticker that is FEDERALLY mandated that we apply to every coach. Not an estimate, but an ACTUAL weight of that specific vehicle. I also freely give that information. In fact, this past year, I put the weights of options on the price sheet so customers are CLEAR that just about every option they take adds weight. Dynamax may be the ONLY RV mfg that does that (I have not really checked, but I have never seen it). All in an effort to give customers the proper tools to make a proper decision.

Is there any warranty on the tires themselves from Ram? Road hazard is one thing...delam is another.

I will have to check, but not sure if the warranty starts they Day we receive the RV or the date Dynamax purchased the 5500 from Dodge? I will try and call Dodge tomorrow and see.

This is our 3rd trip from LA to Florida, but the only trip with tire issues. We have even traveled around the Sierras in CA and no issues.

Not sure what is going on with Continental tires, but will give them a call too.

[bclemens]

All chassis have a delayed start. So the warranty starts when you take retail delivery....within reason. I think at some point, if it is really old, the chassis warranty will start the clock. I don't know that I have a "written list" of that. I seem to think Mercedes would start at retail delivery or 2 years from mfg? whichever comes first. Don't quote me on that.

I know when Dodge had a recall on the Promaster. We had some that were 4 years old we had to call and have exceptions made. USA was no problem (they did it without a call), Canada made it a pain in the behind.

[dannko]

So you never made it to "Amarillo by morning", then of course no way you made it to San Antone

[kaulick]

Having all the tires changed before we got the road again. Not going to take anymore chances.

Some damage on the under carriage of the left side rear wheel well.

[dannko]

what tires did you go back with?

Let us know if it changes the ride or vibrations any?

[janeenb]

Isata 5 DB only 2 wheel drive. Brian, your comment says you try to keep them at 1600 CCC. My sticker shows 816 which is HALF of that. Salesman said oh they just slap stickers on going down the line so it's probably the wrong one .What am I missing?

[bclemens]

My number was where they are at today. I'd guess that is one of the earliest ones built, we've shed a lot of weight since then.

We were also testing the tanks before that stage and some of them got weighed with some water in the tanks.

You should always have your rig weighed at least once, after you have loaded it up for a normal trip.

For anyone else that gets told that same thing...if the salesman says "its the wrong one" then I would request the right one before purchase. They are VIN coded...so it should be an easy check.

[janeenb]

The VIN matches so the 816 on the yellow sticker is right. Unless it was weighed with water then the yellow sticker is wrong?

Just weigh it at the weight you want to travel and compare it to your GVW. That will tell you what you want to know.

Went with the Hercules 225 70R 19.5. Rode nice from Amarillo to Albuquerque. Hercules is made by Cooper Tires. They get really good ratings and less expensive.

To throw icing on the cake of this trip home. Our dinette slide had a fault code and the Multi Plex is not communicating with the wet cabinet showing no voltage. Spent time on the phone with Brandon at Dynamax who was great and helped us override the system to bring the slide in. Going to contact Precision Multi Plex folks tomorrow to see if we can find that error.

The slide might be the panel went bad. Getting for red lights and one green flashing lights. Going to switch out the panel with the bedroom slide to see if that is the issue. Might have to cut this trip short and skip Moab and St Goerge, Utah.

I don’t know what brand of tire you purchased but I have Michelin and they have a chart on line for psi by axel weight. My Isata 3RW has a front axel weight of 3900# and a rear weight of 1160#. That allows me to run my tire pressure as low as 55#. I run them at 60 to be on the safe side. I use the cat scale, it was only $11.00 and they guarantee accuracy.
FYI I weighed it packed and ready to travel with me in the drivers seat, full of fuel and 1/3 full of fresh water. Gray and black tanks empty.

Bill is that weight figured per load on each tire?

No it’s per axle weight. I didn’t weigh each tire indivisibly, just front and rear. The Michelin chart I posted earlier shows the total weight per axle with single front wheels and per axle with duel rear wheels.
