Two questions about Sailun tires

After to many tire problems I am going to purchase Sailun tires this week. Tow questions: 1) how do I know if the aluminum rims will handle 110 psi and 2) a friend suggested running them at less than 110 for less bounce on the highway. Said it would wear a bit quicker. Is that a good idea? Thanks for any advice.

The back of your rims will be stamped 110 PSI if they are built to handle 110. You can run lower pressure if your rig is fairly light without a problem, you can also run 80 PSI if that is all your wheels are made to handle. You also want to install metal valve stems if you do not already have them.

People run them at all different pressures. If you have 110 pounds wheels I see no reason not to run them at 110 pounds. The only downside is the camper will ride a little rougher. There are several pluses including they will run cooler with even less change of a blowout.

I always run at near 110#, but if you want to run less you need to weigh each wheel since they will not all be carrying the same weight and you donít want to run under inflated.

A tire will perform best at its rated pressure. Just monitor for even treadwear. Running a tire 30 lbs below generally increases running temperature and excessive sidewall flexing. If ride is a concern, suspension components need changing, not running tires at 3/4 pressure.

My Monty came with Sailun tires. I take it yours did not. As the manufacturer installed them it must match the rim specs.

I have been questioning whether or not I should keep this Sailun tires and get something better?

I usually laugh a bit when I hear upgrading a Sailun. Something better, not sure what that would be. Hopefully you were not considering Goodyear G614's, IMO , and that of many others on this forum the Goodyear is an inferior tire to the Sailun, and the outrageous price of twice the Sailun.

Stick with the Sailuns, IMO, and many others ,they are the BEST G rated 16" tire you can put on a fifth wheel.

At one time the Goodyears had a terrible reputation, they have improved in recent years, but just review them ,and you will see. Also review the Sailun S637's ,and see what you come up with.

I had my rig weighed at the National Montana Rally. They recommended that I run my Montana tires at 105-110 psi. They also recommend that I run my 2006 Ford F350 dually at 60 psi front and back.

I hope this helps.

You may have take a wheel off and thoroughly inspect it in the daylight for the stamp or raised metal numbers. If your actual weight doesn't require the full 110psi, then yes, lower your psi according to the Sailun chart. You DO NOT have to run the max psi indicated on the tire.

Thanks for all the assistance. Rims capable of 140 psi according to installer. Hope I have same performance with the Sailun as most others seem to have.

Hawk - an installer telling gospel is like the RV Salesman giving me gospel - we all have our humble opinion … unless it is in print, I take it with a grain of salt - IMHO

Thankfully we all can have one! God Bless this country

Great choice of tires I have put 7,000 miles on my sailuns tires and have always ran 110lbs air in them. They still look like new,the Monty tows very nicely with these tires and I have ran over some very poor roads with them. Look on the back side of your rims they should have a stamped air pressure ratting on them.

never said what tires you have on your trailer. if they are 'G' rated then you are all set. but, the psi rating is on the inside of the wheels somewhere.

I have Goodyear Endurance tires load range E, Goodyear has a inflation chart for the tire for the load you are putting on it so you don’t under or over inflate it for your load weight. I would think other manufactures would also

Hi

We donít have any complaint about the G-614 except the cost. We have had 2 sets of G-614 the first set is still going 9 years latter without any problem. The second set blew a tire on me last month but that tire was 6year 9 months old and had close to 50,000 miles on it and should have been removed from service in 2013 because of a broken spring causing the tire to be pulled sideways down the road for a mile or so.

I have just put a new set of E rated tires on to see how they hold up.

Generally 6 lug rims are for 80# E rated tires
8 lug rims are 110# G rated tires

LR E on a Monty? What is the GVWR? Or even loaded weight? I run Sailun at 100 psi on 14,000#.

I have to respond to the comment on Goodyear tires and how everyone knows they are bad tires.
1. Goodyear is the number one tire in the US
2. If you are making a comment on Goodyear's 'RV' tires, the one problem for them seems to be the Goodyear G159 tires.
3. Bottomline is that the G614 which 'we' use are great tires, but, they cost an arm and a leg.

"Run on 110 psi" Is this the cold pressure before you start out or the psi when you have been running which is going to be 10-20 psi higher than cold pressure?

It is the cold pressure.
