RE: Tires- Tires - Tires

I'm sure I will get dinged for asking but maybe overinflation if the tires are the ones FTG found? The weights I saw for that trailer seem light, 14,000 base weight and 2300 hitch. I would think it would be more than that. Those 4 tires would provide 19,220 lbs capacity at 125 psi. I have no idea what you we looking at as our unit has a gross of 17999 and that's only because of the 18K pin box it came with. We've upgraded suspension and king box and are now close to 20K loaded for Full Time, and the tires are rated for 125 cold. My apologies. I was looking at the JD Power listing for a 2016 Redwood 39MB. It shows a base weight of 13,996 and hitch weight of 2274. I thought that did not look right. Hope your tire troubles are short lived.

RE: Sailun 637

I take it back, maybe I did look at some point for the rim capacities but forgot about it. I'm only 5 weeks out from knee replacement but decided I have progressed enough to get down on my creeper and slide under the trailer. I was successful. The rims are rated for 4400 pounds and are 16 X 7. I couldn't find the psi rating but it has to 110 or 120 so good to go with heavier tires.

RE: Sailun 637

Usually the markings ,weight rating ,inflation etc is marked on the backside of the rim , not sure you have to break it down , should be there , unless you have already looked on the backside . I've looked several times and can't find any markings.

RE: Sailun 637

I've been thinking about changing to a heavier duty tire and I'm considering the Sailun's. My problem is I'm not sure if the wheels on my Pinnacle have the capacity for heavier duty trailer tires. It came with 255/85/r16 Goodyear Endurance. Neither Jayco or Tredit Tire and Wheel, their supplier, could tell me exactly what I have. The wheels are 8 lug and the outside width appears to be about 8 inches. Sailun says their 235/85/r16 S637 needs a rim width of 6.5 inches. Other brands give an acceptable range of rim widths but not Sailun. I would hate to order a set and find they wouldn't work with my wheels. No information is stamped on the outside of the wheels. Tire engineer here. Wheels: The best information I have been able to gather is that not only does the government not require a max pressure to be written on wheels, but that wheel manufacturers only consider the max load to be important. I take that to mean that stresses in wheel due to pressure are much smaller than stresses due to the load. As confirmation, I note that when people purpose try to fail a tire by inflating it, the wheel isn't what fails. Allowable rim width range: It's size dependent, not dependent on the manufacturer (brand). That's because there are tire standardizing organizations and they are the ones who set the range - with the agreement of the tire manufacturers. If you see a spec for one brand, it will be the same if another brand doesn't state otherwise. Thank you. I have a friend who has a couple of tire shops in our town. I'm going to take a wheel to him and he is going to break it down and see exactly what I have. I'm pretty sure I have a 7 inch wide rim rated by the manufacturer for 110 psi and 4400 pound load capacity. This would match the Sailun's and several other tires I'm considering if that is the case. My total weight for the fifth wheel loaded for a month long trip to the Colorado Rockies is 14,700. My hitch weight is 3120 leaving 11,580 on the axles. I know getting the heavier tires would be overkill and I would have to adjust the inflation accordingly but I have always been one to err on the side of safety.

RE: It's that time again

I knew there was something I was needing to do. Thanks for the reminder FTG but with both knees being replaced this year I'm not sure I want to be climbing ladders. I may have to hire it done this year.

RE: Replacing solid steps with folding steps

My 2020 Pinnacle came with the Mor-Ryde steps. I park it in a garage behind our house and the distance between the garage wall and the door side of the Pinnacle was not enough to let me bring the steps down. I took them out and replaced them with a set of Torklift Uprising telescoping steps which solved my problem. While doing this I found the frame still had the cut out for the old style steps hid behind the sheet metal skirting. I thought about cutting it out and installing conventional steps but was afraid it would hurt the value. With some trim and proper cutting tools it could probably be made to look like it came that way. Later models may have eliminated the space for the old style steps, don't know.

RE: Will I regret this truck?

I also have that truck. Our Pinnacle has 3120 hitch weight and 14,700 total weight. The truck has over 4K pounds of payload capacity and is really a sweet match up for our fifth wheel. It's the best riding and handling rig we have ever owned in our 40 plus years of rv'ing. I will average around 10 mpg towing, sometimes it goes above 11 depending on the conditions. We've taken several long solo trips with it and the mpg has been around 22 every time.
