  Thank you David, that is good news you have had no problems with you tires. This is the information on the sidewalls of our tires.  Power Towing   Trail Express  ST 225/75/R15   8PR Load Range D   Tread 5 Plies 2 polyester 2 steel 1 Nylon  Sidewall 2 plies Polyester  Max Load Single 2,540 lbs. 65 PSI . I know people are more likely to post a complaint rather than a good remark about something. I don't think we will ever load our camper over 4,000 lbs. The axle is only rated for 4,500 lbs. The tire pressure I think I will keep at 60 PSI, 65 sounds a little high.]]> Fri, 26 Jun 2015 13:36:29 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62378#62378 Tire-ology : Yes, it is only about providing... https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62367#62367 Author: techntrek

Yes, it is only about providing an outlet for those that no longer own pods but still want to hang out here.  I've lost count of the number of posts and IMs that say "we've sold our pod and I'm sorry we need to leave the forum".  We tell them they can stay and many have.
 
No worries about expressing your opinion, Bob.  Remember this forum was started because of censorship (and the denials it was occuring) on the other pod forum.  We've always pledged to maintain a venue that was free of that. 
 
As for critical information, that can be posted in multiple areas and even converted to a forum-wide annoucement if necessary (like the few posts you see at the very top of every sub-forum).  The "pod manual" thread is a candidate for that, hadn't thought of that before.  And, those w/o pods are welcome to read what is posted in this sub-forum, too, like Tars.

Personally, I don't see this as a matter of segregation. The forum was expanded to allow for those who do not presently own Pods to post information that is not necessarily specific to the Pod. We are all free to browse any and all areas of the forum. Quite of bit of the information found in any of the topics could apply to any travel trailer.

I am going to speak for the Admins and Mods and say that we have always welcomed all who wished to participate. All that has been expected is that everyone "play nice". The idea of adding additional section(s) to the forum was discussed and thought about for years.

I voted in favor of expansion. My thinking was: "Why would we want to lose the good fellowship and knowledge of a member simply because they purchased a different camper?

I hope my words are not received as "chastising". This is not my intent. It is not segregation but, casting a bigger net and being overtly open to all - Podders, wannabes, ex-Podders, and those who just like the great bunch of folks we have here. We WANT everyone to look at all areas of the forum...that is why we post.

I only have one gripe about the forum and this is it: I wish folks would quit mentioning CampLite campers - because you are making me WANT one!

You have the SAME tires that I do, except mine are Load Range C. I am into my 6th year of use on them and they have performed well - no issues. I would buy them again, if that means anything. Keep in mind that mine are well within their rating (60%, or less, of maximum load).

Personally, I think keeping an eye on the pressures (not letting them get low) is critical to good safe performance. Also keep in mind, I'm not a tire expert - quite the opposite. How much does your loaded rig weigh? Divided by 2 would reveal the load per tire, assuming the rig is roughly equal side to side.

I just followed a link in the above web site and it reveals some interesting info on trailer tires, per Discount Tire

I look at post using the "New" option. I'll set it to since Yesterday, or the past 4 hours, or whatever, depending on the last time I checked messages.  You can set to look at posts since 5:17 if that was the last time you checked posts.  (You can't set the time, it will do that for you.)  All post, regardless of forum are shown.  If I care, I have to look to see which forum I'm reading at any given time.  Unless I'm posting a new message I really don't care what forum I'm reading though.  I look at the message subjects and choose which ones look interesting or that I've been following.

   Bob I agree inpart what you are saying regarding important safety information that all should be aware of things relateing to safety. I think Doug has done a great job and will continue doing so. And in time if a safety topic of some kind should be created it will happen. Sorry if I am not understanding your post but I hope my reply is of some help. As the safety of our tires I'm hoping the manufactuer has corrected the problems. ]]> Thu, 25 Jun 2015 19:37:20 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62347#62347 Tire-ology : OK, at the risk of being branded... https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62342#62342 Author: coopercdrkey

Agreed. 30psi would not be good. You and I know that with tandem axles, in a turn, at least 2 of them "drag" across the pavement - the tighter the turn, the worse it is. I could see tires popping. So, I also agree on the bias tires. They would be better, IMHO, in our applications, due to the stiffer sidewalls.

I've always inflated my camper tires to 46-47psi - letting the heat build them to 50psi on the road. I'll likely buy something similar to what I have but, it is always good to hear what others think...I might learn something. If I can find bias tires, I think I'd prefer them vs. radials.

The web site has some interesting info, perhaps too much for a simple man as myself.

I know you are good about watching your pressures, so I think you'll be fine. Too much sidewall flex generates heat, which kills the tire. I was following someone on the highway, a while back, who was pulling a utility trailer. One of the tires on the trailer was low (not flat) and the heat was causing the tire to smoke!]]> Thu, 25 Jun 2015 14:41:44 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62332#62332 Tire-ology : Mine were rated online... https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62326#62326 Author: techntrek

Mine were rated online as "6 ply" on the etrailer website, but when they arrived were actually 4 + 2 sidewall.  I didn't go to the extent you did to figure that out.  I wanted to get load range D tires but couldn't find any at the time I ordered.  I wish I had held out because I'm running really close to the max for each tire with the C rating.  I stuck with bias tires since the originals were bias and from what I read they have less sidewall flex.
 
I've always run my trailer tires at max sidewall pressure to reduce sidewall flex, since that is a contributor to sway.  I also run the TV tires near max (about 3 psi less than sidewall).  30 psi would give me a panic attack!]]> Thu, 25 Jun 2015 13:27:22 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62326#62326 Tire-ology : In another post, the subject of... https://www.rpod-owners.com/forum_posts.asp?TID=6491&PID=62322#62322 Author: Guests

In another post, the subject of tires came up. Techntrek had purchased new tires and I will be, in the future. The post brought some questions to my mind, as I consider this future purchase. My investigations, thus far, lead me to the following hypothesis:

I am not smart enough to purchase tires, unassisted. I need someone with a PhD in “tire-ology” to tell me what tires to buy!

Just kidding – there is no such thing as “tire-ology”.    However, this web site, though dated, has some interesting information:

http://www.4crawler.com/Diesel/Tires.shtml

As I look at my existing tires I see – Load Range C, 6PR, and (further around the tire) 5 ply tread, 2 ply sidewall. I thought I have 6 ply tires but , I don’t. I have the equivalent of 6 ply tires! Quoted from the above web site:

“The Load Range rating is gradually replacing the older Ply Rating (as in 2PR) system. Ply rating at one time indicated the actual number of bias (fabric) plies making up the tire, but with the new radial tires, you often only have 2 or perhaps 3 plies making up the tire carcass with some additional circumferential plies under the tread. So a tire labeled "8PR" or "6PR" will likely not have 8 or 6 plies in the tire, but the "8PR" tire will be stronger than the "6PR" tire.”

So, my 5 + 2 ply = 6 (PR)! But, not really. This is because we really don’t use the ply rating system anymore. In my particular case, 5 + 2 = “Load Range C”. Load Range C roughly means that the tire is rated to carry approximately 1750lbs, per tire, at a maximum inflation of 50psi.
   
These are the maximums but, my camper (having 4 tires) is carrying roughly less than 1000lbs per tire, when fully loaded. Reading down the web site, regarding inflation pressures, would indicate, to me, that putting 50 psi of air in the tires is actually over-inflating the tires. There is a somewhat linear correlation between load and inflation pressure (as stated).   Since I have about 60% of the rated load on the tires, I should inflate the tires to roughly 60% of the maximum (about 30psi) and then test for proper tread contact with the pavement – adjusting as needed.

This just seems a bit low, pressure wise, to me. And, at this point in the thought exercise, is about where the hard drive between my ears overloads and crashes. The only way that I can get it to reboot is to go into the other room, eat some cookies and, watch “Gilligan’s Island”.

So, your thoughts/comments are welcome.
