Sailun S637 or Goodyear G614

For those of you who say that the original poster could run the G614's with 80 PSI, I expect that Goodyear's weight/vs pressure tables might bear that out but I prefer to carry higher PSI in my tires on a trailer with similar weights. I always run 105 PSI and can see no unusual wear after 3 years and 30,000 miles.

I know that under-inflation is one of the biggest problems with trailer tires but I've never seen any indication that over-inflation (as long as it is within the wheel/tire's capability) is an issue. Sure, the ride might be harsher but I don't see any evidence of that in my trailer's contents and doubt that 80 PSI vs 105 PSI would be noticeable at all in the trailer's ride quality.


I will err on the side of carrying too much PSI rather than too little....

The reason to run what the weight charts say is because in wet conditions you won't have as much stopping ability and the centers will wear pre maturely and the trailer won't track as well if over inflated. Per GY Tech Support.

When I went from E to G on my Avion I talked to GY Tech Support and they said to weigh each tire then use weight chart based on the heaviest tire then add 5psi.

Do what you want, but that is what GY Tech Support recommended. May be worth a call.

The GY G tires that came on our 07.5 Mobile Suites were made in early to mid 07. We never had a flat in 5 years and the spare never touched the ground. From what I have read the 07 and newer G tires have been very good. But the nay sayers will always say they have lots of problems and not mention that was 7 or more years ago. I put a set on our 02 Avion Platinum in early 07 and they looked great after 5 years when we traded for the MS.

C'mon, give it a rest. No one is badmouthing Goodyear's tires here, some of us just want to spend less money. So I don't really think I've seen any "naysayers" on this thread. Until now that is.

AMEN!!!

I guess my above reply goes for you too!

G614's came on our fiver 7,000 axles, actual weight 12,500 I run 110 psi as driver side is kitchen/entertainment slide. Replacing with G614's, existing tires wearing well but close to 5 yrs old.

The reason I asked for approx. build dates was to see if they some of the older tires made and if any of your newer tires have had any problems.

My Dad was told to run 110-105 be GY Tech Support and has had no problems and even wear since around 07.

The earlier tires that came with my Dad's HH Premier did have problems and GY Paid for damages 100% no questions asked.

now that you mention, the failures were with tires that would have been made sometime in late '06 .... our camper came with Load Range E Kenda Loadstars .... they were horrible tires and we went through 6 of them in less than 8 months .... now that you have me thinking about it, I do recall being told back when we were having the problems with the G614's that there had been some tires sabotaged during a strike at the plant where they were made .... have no clue if ours was involved with that or not

What is the GVW of your 5er? My 5er, a 39'6", 4 slide HR with a GVW of 16,950 came with the GY G614's..Manufacturer of my 5er recommended running tires at 110 psi, as did Good Year....I spoke with a Goodyear Rep at a Wingfoot about 2 weeks ago and again was told the same thing. I asked him about using the scales to take the weight of each tire and use weight tables and was told what I already knew. "IF" one wants to go through that, go ahead, but your covered, with no effect to the tire if you run at max sidewall pressure, less heat build up, best wear pattern, again, that was a GY rep. I've had my best wear and no heat issues running my tires with my 5er loaded to about 15,950# @ the recommended tire pressure of 110 psi...

believe it or not, until a few minutes ago I've never bothered to so much as look at the weight ratings of our camper .... we are currently spending the summer in our '06 Sunnybrook Titan 34BWKS so as to answer your question I went over and checked .... its UVW is 13,248 lbs and its GVWR is 15,000 lbs .... what it weighs as it sits, I have no clue and really don't care .... guess it shows that I pay very little attention to such things .... we now put on a new set of G614's just before the ones in use reach the 5 year mark and as a side note we have never managed to wear out the tread .... all of the failures mentioned earlier have taken place when trying to stretch their use past the 5 year mark .... in all three cases the failures took place during long summer trips where the temperatures were in/above the upper 90's .... that period was also one in which were still working and the camper sat for longer periods between use

What were the approximate build dates of the tires that went bad? How many miles were on the tires when they blew?

As you said no way to tell what caused the tires to pop. So GY still stepped up and paid. No tire company will pay for road hazard but from the many posts that I have read and from personal conversations they still seem to pay when is is a vague situation.

sorry, I don't recall the build dates but when we buy tires I require them to have a build date that shows they are less than 6 months old .... miles is another thing, we are on the road for 6 - 7 months a year so I tend to believe we tow more miles than most .... we are from NC and spend the winter in Texas and the summer in SD .... as a pure guess I'd estimate abut 10,000 miles a year .... G614's run 110 psi (we actually keep the cold pressure of ours at 100 psi) and, at least for us, when they let go, they really let go .... the part that was still on the rim has been pretty well shredded .... I really don't believe that it would be possible to tell the cause from what is left .... with us they have paid 100% all three times

You are probably close enough to your tires has weight to run 110# with no or little ill effect.

You will get a different story from GY Tcch Support than a Wingfoot rep. The Tech will tell you if your loaded weight is much under the max load for the tire it is advised to use the weight charts. Example going from an E to G tire. They will not contradict what the trailer mfg has for psi. The fact is most RV's need to be at max psi becaust the trailer mfg only supplies tires to just make the grade with none or very little cushion.
