We just got back from a two week trip from Texas to Tennessee and back in our 31ft Class C. We are just about to turn 30k miles on the coach and it has tires that are a little over a year old with less than 10k miles on them. I check my pressures every morning and fill as necessary. But unfortunately we experienced tread separation, again, in Louisiana. We were blessed that it happenned on a Saturday early and that we were able to get someone out within an hour and we were back on the road within 2. This will mark the second time this has happenned in the past two years. I went through the scales the next day and we weighed in at 1k below gvwr and was also below on each axle.
I have been convinced that class c's are at chassis limits, even when they weigh in below gvwr. My class c snacks on tires, having gone through 14 in 3 years. Okay the first 6 don't really count because I replaced them when I bought the coach, and the next 6were cheap models. But the new ones are BFG commercials, yes I can be taught
We had been thinking about upgrading to a class a dp, but have been reluctant because I have 4 children and the sleeping space in the c is nice. Bunk models of class a's seem to be a lot more popular now and I think we could use the space. After this last experience I am starting to feel strongly that a class a might solve this tire snacking issue. I see issues here on class a's tires, but does anyone have any experience on the the reliability of the tires on class a vs class c? Is this a dumb reason to upgrade?

2003 31' Gulfstream Independence - We love to RV with our 4 children, ages ranging from 6-15
Our main reason for upgrading was so we could tow a horse trailer on occasion. I don't think your reason is dumb at all. I'm just sorry we hadn't done this sooner. AND being a new owner, I'm partial to Newmar's . This one has bunks.
I think the family would appreciate the extra space too.
After considering the options, I started by looking at DPs. We still upgraded twice, but I think we're done now. We really like the one we have and I haven't seen anything that would make me even think about upgrading again.
@sully2 I am running 225 75 16s at 80lbs, I checked the pressure that morning about 200miles before the issue
@mena661 we love the Newmars, they are on the short list.
@pianotuna I am a middle or right lane driver and drive 55-65mph most of the time, slower as needed for conditions, wind etc. But as a result of this slow lane driving I often end up drafting trucks or other slow moving vehicles. I wonder if the buffeting that you get while drafting might be causing this? Maybe 31ft is just too long for a class c?
I obsess over tire pressures, checking all 6 every day while travelling and filling if they are even a single pound low. I also check them at least once a month while parked. Although we use our rv a lot so it is rare that a month goes buy that I am not taking it on a weekend trip. Tire maintenance and pressures are Always the top item on my check list and are always top on my mind.
Do you folks that have class a's have to think about tire pressure as much as I do?
