I just got off the phone with Forest River. I simply asked if they would buy the OEM tires and give me a credit towards better tires. The answer was interesting. He (very nice by the way) said FR does not recommend going to a higher LR tire. It adds extra weight to the axle (65 PSI vs 50-55 psi) that was not in the design consideration. As such they do not recommend doing so. He did say that if I did so (to a D LR) I would be okay as long as I understood this reduced the amount of load I can add.

He also must be familiar with this forum. He said I suspect you are hearing this on a forum on the internet and it makes a single blowout feel like a thousand of them. He does have a bit of a point there, however I do have a friend at church that has experienced blowouts on his trailer (not a FR) and that was the first thing he warned me about as well was to improve the tires.

In the end he said as long as I keep them inflated properly and don't "take 90 degree corners at 60" these tires should do fine.

He also said that when a customer experiences a blowout they try very hard to take care of the customer. However in his opinion most of them are caused by overloading the trailer and improper driving.

Comments?

You do not need to go to "E" rated "D" rated is fine and then run them at 65 PSI full CP. I do not like running tires under the CP rating. A "D" rated Marathon at 65 lbs CP can carry like 2350 lbs were your "C" rated maxed out at 1795 lbs. You will be making a mistake going to "E" rated with those rims. The 1st year I went to Calf. and Oregon on the "C" rated. Had a blow out 6000 miles. Then I went to the D rated..... Why would you go to "E" rated then have to run them under inflated? That's even worst IMO. We all know that they are bad, but how bad is the question. I would spend the money on a TPMS get it installed and be on your way to the Golden State.

As I stated earlier, LR D tires are all you need. If you do end up with LR E, you can run them at 70psi as I did. No issues at 70psi for 25,000 miles.

The tires Forest River puts on the 8289 are the bare minimum for an RV that size. I switched my tires over to E's and what a difference it made towing the RV. I don't have an RV that roams all over the road any longer. By the way, I changed tires because by the time we had our RV 13 months the rubber was starting to split on the factory tires and one of them started to leak. Piece of mind= new tires.

Hello Ed,
We just put our new 2015 82829WS into service about 2 months ago. Our 4 trips so far have been short drives and 3 or 4 nights each. We love the unit (our first). We recommend the second AC unit - you never know when the temps will take off. So far, the 5th wheel has been superb. No real problems. We did notice the plastic indentations near the top of the front nose cone. Haven't asked the dealer to fix just yet. Good luck in your new adventure!!

How about a winterization question. We want to use our new trailer this winter occasionally to have a little fun. I see temps here in SC are going to get lows in the upper 20's (mostly in the lower 30's for lows though) over the next couple of weeks. Probably pretty much like that all winter.

How do you handle winterization if the 5er sits 3-4 weeks between usages. Do I need to winterize and de-winterize for each trip?

Sounds painful.

I'm not sure where the "recommended" 80 PSI came from. That may be specified on the tire but through other discussions, the tire pressure is to be determined by the tire load. There are charts for this. The recommended pressure on the label on cars or pickups doesn't correspond to the pressure on the tire but corresponds to the maximum weight on that axle. I've run my Load Range E at 65 PSI cold and covered many thousands of miles. This was an arbitrary decision on my part but haven't had any rim issues nor have I read of any on the forum.

Honestly no matter how hard I searched I could not get a answer on the rim ratings. The Supplier lionshead could not say when contacted. Research on other sites showed no results. I run 60 psi on stock rims with D tires. E at 80psi I would concerned also the ride would shake the trailer to pieces.

This discussion has caused me to look further. Looking at a tire pressure load chart-http://www.goodyearrvtires.com/pdfs/rv_inflation.pdf, for the ST225/75R-15 tire on my camper, shows that at 50 PSI the tire will carry 2150#. The individual axle rating on this camper is 4000 and weighing mine loaded, the heavier axle weight was 3800#. It looks like I can safely drop my pressures back to 50 PSI. Dropping the pressures is easy compared to resetting the monitor!

Brain this is what I got from Lionhead, also good year inflation chart. read the last paragraph.
