Boat Trailer Tires?

I have a new Ez Loader boat trailer and this morning I noticed that the tires were made in China. They are named Rainer.
Has anyone ever had any problems with this tire?
I have read that people with RV trailers that came with China tires have had a lot of problems with them. Different name than the Rainer tires.

Also the trailer has oil bath hubs and on the inside of one wheel I notice that there is a small amount of oil.
Is this something I should be concerned about? The sight glass does does not indicate low oil.

Thanks
John

Agree with your statement. I feel like I have to much invested into what those tires are carrying for any doubt with air pressure and load rating. I check trailer and tires before every outing and make sure I don’t load the boat with any extra weight were it should not be. I even moved the boat forward on my trailer 8” to ensure I always have the correct tongue weight with addition of motors and extras. Not worth the risk to you or others not understanding your trailer and cargo.👍🏼 better safe than sorry.

Lt tires are not designed for trailer use and are not a good idea. What you’re looking for are ST tires which are more durable and stronger for trailering use.
My 5th wheel came OE with ST tires. They have a higher speed and weight rating.

If Ez loader put those tires on the trailer they are probably adequate. More info on the boat size, and weight plus the rating of the trailer load would help. Also what is the load rating of the tires. There is too frequently a case where dealers put marginal load capacity trailers with boats to reduce the package selling price which causes problems down the road....literally. Happened to me and I had to buy a higher capacity axel.

The Dept of Transportation says that tires over 6 years old should be replaced, especially if they are on vehicles left out in the elements. Also car and truck tires do not have enough side wall strength needed for trailers so don't use them on a trailer.
As far as the oil lubricated bearings. There seems to be mixed reports but a common recommendation is to carry extra caps and oil in case you damage them on a curb. For your possible leak, clean it (brake cleaner works) and see if it comes back. If so you should replace the seal....be sure to get the seal with twin ribs.

Chinese factories build products to a specification/price point. They can build very good things, or they can build total crap. I agree with LGB... EZ Loader probably didn't put totally defective tires on the trailer, but they are also probably price-point tires ("good enough" tires).

You will have a hard time finding non-Chinese made trailer tires in stock, anywhere, with the exception of Goodyear Marathons (you can find these at America's tire in common sizes).

Personally, I like the Marathons, or Hankooks, Kendas, or Maxxis trailer tires (US, Korean, and Taiwanese made).

Most tires are made over sea's but there are a few brand name ones made in the USA. If you look at your brand name tires like Cooper some of them are made outside of the states also. I did some research and found that all tires have to meet a DOT standard to be sold in the USA no matter where they are made and that stamp is on all tires made for sale in the USA. For you that are wanting to go buy Goodyear Endurance tires if you do your research they are most likely made in Taiwan. For the last ten years I have been buying all my tires online and some being brand name and others that I have never heard of and have never had any problems. Out of 5 vehicles I have none of the tires were made in the USA including a set of Goodyear Endurance and a set of Cooper all-weather on the car. If you think about it every car that is made outside of the USA and sold in the states has tires made from a foreign country including your brand name vehicles.

I’ve always had a habit of getting new tires on every new trailer I acquired over the years. My tandem axle trailer tires for our Bluewater boat are about 4 years old now, and I’m thinking I should have them rotated and checked out good. We typically do a dozen trips a year to the coast, and a few high lake trips every year, besides back and forth the the CR and Willamette. So I’m guessing I’ve got about 10K miles on them.
Time to run by LesSwab again me thinks…. I’ve had real good luck with LesSwab tires on vehicles and trailers both. Kirk

I just replaced the tires on my 10k Karavan trailer. Decided to increase from "D" rating to a "F" rated radial tire……substantial side wall thickness. Greenwall is manufacture, China made. Many construction contractors use a F or G rated tires on their heavy haul trailers. Still has the 'ST" rating for trailers, because of the required sidewall construction for trailer tires.

Tire brand and wear come in second to how you tow. Heat is your tires enemy which boils down to tire air pressure axle alignment and balanced axle loading. That trailer was designed to be towed level to the pavement. If it’s not your increasing the load on one axle while decreasing it on the other. I think we have all seen trailers behind a truck that looks like it’s going up hill. I leveled my trailer on a level floor using the tongue jack and hand level until the bubble was centered. I then measured the hitch then hooked up the truck and measured that after the weight was on the ball. It told me truck hitch needed more height. I ended going with a 4 inch lift and even that was an inch shy but better than it was. I would not have believed I needed that much change by just looking at trailer.

Both my boat trailers are due for new tires. Did my own suspension last year, but I don't have the equipment or know how to mount my own tires on the rims.

Are most you guys doing your own or taking them to Les Schwab or other tire place? Time for me to start shopping around so open to suggestions.
Mounting most tires requires specialized equipment and can be dangerous if not done properly. I'm a mechanic. I install all kinds of tires from passenger cars to heavy equipment but I'd never try to install my own tires at home.
