Over All Consensus

[socalhd]

It’s time for me to change out tires and the information provided on the Internet gets confusing and sometimes argumentative.
My rig is a 2014 Fuzion FZ342 with 2 axles. I still have the factory Trailer King Tires 235/80R 16
My Rims are 6 inch wide and rated at 110 PSI
I do not intend to buy new rims to accommodate the Sailon or the G614.
Is the Goodyear Endurance my next best option??

[ChuckS]

For the weight of what you are towing Id have to get the Sailon tires and I would not give two hoots or hollers that the wheels are only six inch. As you stated they are rated for 110 psi and that’s what I’d run with that toy hauler..all metal valve stems as well.. the G614 is nice too but price wise the Sailon would be better.. and I haven’t seen anyone complain about them..

I’d still keep my tow speed between 62 To 65...

I opted for the GY 614s when we ordered our 16.5k 5er & had no problems with them. When it came time to replace them (approximately 60k miles) I found I could order 17.5" H rated Sailuns with wheels & new lug nuts shipped to my door for less than replacing the 4 GYs, accomplished 2 things, new tires & no more tire worries. So far have about 6-8k miles on them & very pleased with me choice.
I sold the used GYs with wheels & lug nuts for $500 to fellow with much lighter 5er making the swap even cheaper.
Check out Performance Trailer Braking, they also did the disc brake upgrade at my site.
Personally on a toy hauler I wouldn't go less than a G rating which run at 110 psi.

Are Sailuns Trailer Tires or LT tires?? This sounds like the most viable option

[travelin texans]

I have them on my trailer, so mine are trailer tires! LOL!
I'm guessing trailer tires, don't think I'd want 16 ply tires on my truck.

Info for the Saliun tires... it appears to be an excellent choice

Carbon 327 - Another +1 vote for Saliun.

[Tinner12002]

Yes, Sailuns are trailer or ST tires. Came factory on my Raptor in 235/80/R16.

[notanlines]

+1 on the Sailuns. 3 years on the Raptor.

Okay guys thanks for all the info.
After checking with local tire shops and getting price quotes here is the outcome.
I ordered the Sailun S637t 235/80 R 16 from SimpleTire online. Per many recommendations.
Price was less than $600. Shipped to my door and Discount Tire will Mount and balance for $25. Per. I priced the G614 at Discount Tire and they would have been close to $1500. Installed.
My wheels already gave the steel High Pressure Valve stems which is a plus.
Again thank you for the informative input

Sailun ST tire spec sheet.
Note the rim width.

"Tires should only be mounted on approved rim widths. If changing tire size, the rim/wheel must have adequate load and inflation pressure capability. For rims/wheels not so identified or for service conditions exceeding the rated capacities, consult the rim/wheel manufacturer to determine the rim/wheel capabilities." (On page 37 it's recommended to consult with the vehicle manufacturer about bead seatings).

http://www.sailuntires.ca/images2/637/637st.pdf

I contacted the Sailun rep that I got the tire inflation chart from a few months back, asked him about the rim width discrepancy (most of our wheels are 6", Sailun spec sheet indicates 6.5" for s637t tires). Here is his response:

"In regard to your question about wheel width, a 6.5” wheel is recommended, however; the 6.0” and 7.0” wheel width is allowable. There is no risk around the safety of the tire in your application.

There could be a minimal effect on the wear on the outside rib of the tire. The narrower wheel “pulls” the beads of the tire in slightly. This can cause the footprint of the tire to not sit completely flat on the road (shoulders slightly raised off the road). The result is possible irregular wear on the shoulder. This situation is compounded if the inflation pressure is higher than the recommended pressure. It sounds like you have a pretty good handle on your inflation if you are following the chart. Just keep an eye on the shoulder wear. If you see irregular wear start to develop, you may be able to lower the pressure slightly if you have 10 psi of safety built in. Don’t go below the recommended pressure though."

[Tinner12002]

Just as a side note to the tires, Sailun recommends 6.5" wheels on their 235 series tires. I looked on Trekwood rv parts to see if they had wheels and tires for mine which they do but wheels are 6", not 6.5" as per recommendation I seen from Sailun. I guess the 6" must be .50 cheaper so that's why Keystone uses them...lol!

I am running the "Provider" Tires that came on our Laredo and they are serving us well. ST235/80R16E If at the end of 4 years they are still doing there job I will replace with the same.

I have seen a lot of posts about tires, the different makes and different ratings. We just bought a 2018 Cougar 25RES and it has trailer king st radials 225/75r15 load E 80 PSI. Can anyone break all of this down for me?

Goodyear Endurance, probably good (too new on market to know how they wear yet.)

Are these something that will at least last me for a while? What kind of speed rating?

[JRTJH]

It seems that on this forum, the general consensus is to get rid of them, the sooner the better. The argument most have is which brand to use as a replacement, but for the most part, we all agree Trailer King is not a brand to trust beyond the driveway....

You may get 10 years of reliable service from them. That's 5 years beyond the recommended "age out" time frame. Then again, you may wind up with $8,000 damage to your trailer on the first trip. It comes down to whether you're willing to gamble or not? Some are lucky, some aren't.... How many lottery tickets do you buy and how often do you win????? That might be an indicator of whether you should trust your TK's..... Then again, maybe your luck will be different...... Too early to tell, eh? :hide:

ADDED: As for speed rating, if your tires have no speed rating marking on them, then they are rated at 62MPH, if they have an L the rating is 75MPH and M is 81 MPH. But most of us would advocate to never drive faster than the speed limit and certainly well below the 75 or 81 MPH rating of the tires. After all, a 6000 pound trailer with "magnetic brakes" may not stop as rapidly as you'd need in an emergency.

The normal procedure for rim widths is to establish an acceptable range. It might be 6" - 7.5''. Within the range the tire manufacturer will establish a measuring size. Their tire fitment specs will correspond with the size of the measuring rim. With a single size recommendation such a 6.5" there is no wiggle room. Saying something else is hearsay without a published standard.

When a rim is marked with a single width it's the vehicle manufacturer's responsibility to waver it's uses with any tire fitment that is not a standard fitment for such a rim. That's why the vehicle certification label has basic wheel sizes on it such as 16x6J or 16x6.5J and so forth.

Looks like the Carlisle are the cheapest option about $70

[JRTJH]

A number of us are running the Carlisle Radial Trail RH or HD (HD superceded the RH). WalMart has the best pricing I've found on the 225 75R15 LRE tires at $67 each. Some WalMart service centers will mount their tires free, but most will not jack a trailer, so you'll need to remove your wheels and take them to WalMart. Alternatively, you can sometimes get Discount Tire to price match the tires or buy them at WalMart and take them (with your trailer) to DT or another tire store and pay to have them mounted. I'd urge you to also have them balanced.

Our 371 Fuzion came with 637 Sailun's 235x65x16 G rated 14 ply. Built like a commercial truck tire and no problems running them over 3 yrs.

I replaced all 5 stock Trail King tires which were equipped on our 5r which only had about 300 miles on them (dealer to home/Home to where it was parked while I worked away from home) with new Carlisle tires I bought at Walmart, and had them installed at a tire service center; and spent about $500 (tires were about $350 shipped to my local WM store, and the install was about $150). I then sold the take-offs on Craigslist for $250. The Carlisle in my situation are great tires. I also installed a TPMS system, which helped me keep an eye on them on our last summer trip.

Just courious why you didn't just purchase the tires at Discount Tire?? They, well I should say my store here in town, will match prices including internet pricing.
