tire blow out

[lee_worsdell]

Well had my first blow out yesterday just south of erie. Little scary changing on the side of the road. Driver side to good thing the interstate wasn't busy did it in between cars. It was a goodyear marathon. I was looking at sailun s637 st .I noticed there are 3 16inch sizes. My rims are good for 110psi which size should I go to. st235/80r16 or st235/85r16. THe 85,s are one inch taller which my trailer does run nose high and that as low as I can get it so that would help if they fit. any ideas and just on sailun

Put the Sailun S637s on our Jayco last year before leaving for Alaska. 10,500 miles later we had no issues and the tires still look like new. Everything I read on here was positive and my tire dealer recommended the Sailuns for heavy duty trailer use.

If you have Es now and have any indication you might be too heavy then go with the G rated tires as they will give you a little cushion from possibly being overloaded. If you have the room and still need more height then go with the 85 series but make sure you can tolerate the tires being an inch closer together.

I'm just leary of any ST (China made) tire. I had a failure on a travel trailer in 2nd season and checked them prior to each trip for proper pressure and never traveled over 65mph. On 5th I had failure start of 3rd season. By that time I felt like a tire expert and also added TPMS and checked every couple of hours on road for pressure and temp. and still had failure. Also learned that if one fails you can usually expect the second one on same side to fail in 100 miles so I carry 2 spares and when one fails I change both. Both failures were from belt shift (lousy manufacturing).

^^^Depends. Are you talking total weight on the axles? If so, maybe. If you have 12,168 lbs. exactly divided among the 4 wheels, you'll just make it. However if you have a wheel or two carrying more than exactly 1/4 of the total weight, then you'll be overweight on those tires.

It's entirely possible to have two tires carrying 3,500 lbs. and two tires carrying the remainder. That puts you overweight on two tires.

I had two Marathons blow on the same trip. I filed a claim with Goodyear and they paid for the damage to my 5er and replaced one tire. I kept both tires and they had them sent to the factory for inspection. I went with the 235-85-16 Sailuns and they have been great so far. I even had them moved to my new 5er when we traded last May.

So will the LT235/85R16 E carry 12,168 lbs.?

LT's

A LT235/85-16 E 80 psi has 3042 lbs capacity for 6k axles and smaller.

A ST235/85-16 E 80 psi can have 3640 lbs capacity for 7k axles.

A LT simply isn't up to carrying those heavy loads.

The OP didn't say if his trailer had 6k or 7k or 8k axles axles.

Sailun S637 has gone after the commercial trailer market (regional service trailers) with a ST235/85-16 G load range at 4400 lb capacity and more importantly is a 12/32" tread depth for more mile of service. These tires are popular with trailer owners who have 7k or 8k axles

The ST235/80-16 G 4080 lbs and has 10/32" tread depth. RV folks seldom actually wear out a tire so a thin 10/32" tread works fine.

OP ....the 235/85 tire is around 1" taller which will raise the trailer about 1/2".
Sailun S637 service record is tops with all types of trailer owners.

If you have the wheel clearance go with the 85s. If I can remember correctly you only need about two inches between tires. Someone will correct me if I'm wrong about that.

Make sure you have enough spacing between your axles for the larger tire. I wouldn't be able to go with the 85 instead of the 80, make sure you can.

Also, width is critical in many cases to avoid rubbing against fender skirt or other areas.

Sailun, now has a S637 ST235/80R16G to match the diameter of maypops. Chris

Hi, we feel your pain... had two Maxims blow out on us one trip 3 years ago. We switched to the Sailuns, on our 5'er and never had a problem since. As for size, since you are running nose high, go with the 80's. Good Luck and Happy Camping !!

Are you not backwards, why not the 85's to get his trailer a little higher, and eliminate some of the nose high.

If you insist on ST tires despite all the negative comments over the years, Salune or Maxxis seem to be the best.

Can't speak for Maxxis, but Sailuns are the best . I am sure you are aware that Sailuns were an LT tire not long ago, but changed to an ST tire for import reasons. Same tire as before.

Not sure where you got your information on the negative comments for Sailun ,but I have yet to read one.
