Sailun S637 or Goodyear G614

Below is a Bridgestone tire reference. Even though it carries a 2006 date it was published after the 2007 tire rules were made public but before they were enacted. If you don’t take the time to read the entire document or just take some statements on the first couple of pages out of context you will miss the statement on page 15 quoted below.

Never select a tire with a smaller size, or with less load carrying capacity, than the tire specified on the vehicle tire placard.

Instead, I'm going to go for some new G load wheels and G load tires. With 3750 capacity per tire, I figure I have a greater safety margin and won't be anywhere near overloading which could happen with the E load tires. I've narrowed it down to the Sailun and the GY614.

Is it worth $480 extra for the GY's? I'm dumping China made ST's and not sure I want a China made LT - although the Sailun seems to have a pretty good reputation.

Go with the G rated tires. You can't go wrong with an extra margin of safety. Good Year has been outstanding in replacing my trailer tires when there has been issues. In addition they paid twice for all the trailer repairs from the damage caused by blow outs.
$1500 and $1200.

Initially I was going to go for some E load Bridgestone Duravis R250's or Michelin Ribs but they only have a load capacity of 3042 per tire - kind of low considering my GVWR.

R250 or RIBs will do just fine. I would however not but put a poly carcass E rated tire on it. If you run the G614 or Sailun according to the inflation chart they it will be at 80 lbs, the same as the R250 or RIB. Why waste the money on tires that do not have the track record of the R250s and RIBs? Chris

I run the GY 614,S 14750 GVWR 6000 lb axels, i am heavier on the fridge side and would be over on any E rated LT hence the G,s. You may want to weigh your sides as opposed to just axels.I got about 40000 miles out of the 1st set of GY,S with no problems at all.

Donn...I should have also asked for opinions on sticking with the 3042 rated tires as compared to going up to the G loads.

Based on your comment, appears I'm going overboard???

Ok, I will bite!

Yes the GY G tires are worth every penny (IMHO) I have had two sets both for 5 years and never even had a flat. One set on a rig about your size and one set on my MS in sig.

Really doubt Sailin will cover damages or even a tire but GY sure does if it is not a road hazard.

The GY G's have been very trouble free over the last 6-7 years. Older ones did have problems but they did stand behind them.

US Made or China, it's up to you.

Some will tell you either won't work because your rims won't handle the air pressure. Based on actual weight on each tire you will probably only need 80psi anyway.

And some will tell you you have to use Max Psi or you will ruin the tire. Not true that is what the tire inflation/weight charts are for.

My Avion had E tires and 80 psi rims. I ran the tires at 85 psi for 5 years and they wore evenly.

Some posters will swear by the Goodyears because some people who have had blowouts with Goodyear G614 tires have had the damage covered by Goodyear. Did Goodyear cover all damage by all people who have had damages? Hard to say, but they have covered some. There is no guarantee that the damage will be covered if Goodyear decides the tire failed because of road damage.

Other posters, me included, have decided they don't want to spend the large sums of money necessary for the Goodyear tires and have gone with the Sailun S637. We are gambling that the tires will not explode and damage our trailers. I spent $1307 for 6 Sailun S637 tires, that included shipping, and mounting and balancing. Will they last? Dunno, but it's worth a shot IMO.
