Title: HD trailer tires
Post by: transamz9 on April 26, 2017, 06:46:50 pm
Now that's a tire. Tire of changing tires on the side of the road. Just installed a set of Sailun 637's and man these things are heavy.(https://uploads.tapatalk-cdn.com/20170426/30db23208f43a3ca29d3c66ad2ddc123.jpg)

Hope they fix the issues. What's the speed rating?

following...need to replace my china-bombs before we head to Colorado this summer and never thought to get a commercial grade tire on the trailer...not a bad idea...especially given how the Ram 3500 wants to run!!

I'm not one to discriminate where a tire is made. I just go for what works. My 5th wheel came factory with GY Marathons and I had always heard they were not a good tire for something that is always heavily loaded. I knew going in that I would have been replacing them but I didn't figure on two years having so much trouble no more than we travel. We have run Sailuns on our dump trucks and semi with good results so I thought I would look into them. I didn't even know they made a 16" tire until I looked. They only make two sizes (235/80 &235/85R16 in the commercial side. My RV runs heavy on the axles because of the 500lb tongue weight of my boat so it only made sense to find the heaviest tire possible at a reasonable price. The GY commercial tires are stupid expensive @ $300+ per tire. I would have added a third axle before I would have paid that. LOL I put the 235/85R16 on my RV with a 4400# rating and a 75 MPH speed rating. I will feel much better now when the ole Cummins is chugging along @ 85.............

That's a good looking tire. I like the solid shoulders on a HD trailer tire, especially one that gets dragged sideways like on our RVs. Another tire I ran on my last RV is http://www.goodridetire.com/index.php/products/info/stzc/244 (http://www.goodridetire.com/index.php/products/info/stzc/244). These also look like a good 14 ply http://www.goodridetire.com/index.php/products/info/cr960a/446 (http://www.goodridetire.com/index.php/products/info/cr960a/446) . I really like the more squared off look of these and the Sailuns.

I would take a look at Bridgestone Duravis R250's.  Massive upgrade and they are NOT ST tires.  They are commercial LT's with a speed rating of 99mph IIRC.  Discount Tire guy here said many full timers who come in either go for these if they need an E-rated tire or the Goodyear G614 if they need something more.  Google the R250 and see what you come up with - even the people on RV.net say nice things about them.   :o :o :o

That tire don't have the capacity I need. The 235/85r16 on good for a little over 3000#. The Goodyears are too pricey and still don't have much more capacity that the 10 ply tire that I had.

Those Sailun's are pretty beast.  4k LCC per tire.  I am going to try the new endurance - don't need anything that massive.

I wish I could Tranz - 15" wheels for the moment is all I got.  Might go to 16's in the future!  Happy trails :)

I just wanted to do a little follow up on the Sailuns  I put on. I really don't have any hard fuel mileage numbers because well.......I really don't care. It is what it is. LOL  I also drive with traffic so one trip I might keep it around 68 and the next trip we are liable to rolling along at 75 so it would be hard to get a good number anyway.

What I can tell is they have a lot less rolling resistance and it's pretty noticeable. The way I'm judging this is very complicated and scientific..... :rotfl: :rotfl:.

There is one place we go that is all 2 lane the whole trip and just outside one town there is a hill that is about a mile long and is "flat" the whole way up. What I mean is you can see it, there is no up and down in the hill it is just flat straight up at the same grade when you hit it. No matter how I hit it, at the 55 MPH speed limit or at 65 it don't matter with the old GY tires about 3/4 the way up I was at 55 MPH foot on the floor the whole way.  It would get to 55 and that's where it would stay the rest of the way up. The last trip we took was the first trip with the new tires and it was 57 MPH. We have made this trip probably 15 time in the past two years and the results were always exactly the same ,55.

Another way I can tell is on the interstate it shifts much less out of OD to 5th. Before, a bump in the road would make it drop a gear but now it takes a small hill to make it drop a gear.

The other thing I like about them is how well they hold up when jacking the trailer in and out of a tight turn. With the 10 ply GY's it looked like the tire was going to pull off the wheels and the wheels look like they were going to break off the axle. Now it just looks like the wheels' going to break...... :rotfl: :rotfl: :rotfl:

So far I'm pretty happy with the results.

Thanks for the report Trans.  Good to hear that the lower rolling resistance has helped MPG's.

Funny how things seem to come up once you start a project. I decided to start the research for new tires since ours are 6 years old. I am still tossed between the Goodyears and the Sailuns. Guess i'll have to flip a coin because they both seem to be really good.

OK so I decided to go with the Goodyears. Install went well. Only got to tow it from tire shop to the storage but it seemed to tow a bit better.

Will be doing first trip in a few weeks and then a longer trip at the end of the month.  Hoping for the warmer weather too!!!

I noticed a big (much better) difference in the towing when the Goodyears were installed.  Here's to many happy and safe miles.   :cheers:
