Good ole BlowMax tires

[vr200275]

Was planning on upgrading tires, Guess I waited a little too long:S

I am planning on going with Sailun S637.

My wheels are only rated to 94psi.

Does anyone know the weight rating of Sailun S637 tires at 94psi?

I have three 7000lb axles.

Yeah ...just look at other trailering forums (non rv and rv) and we see all sizes of blow max issues.
safecar.gov tire complaints website has 14"/15" 16" and popup trailer size ?? tow max tire complaints.

ST tires have always had issues even when they were all made in the USA and the national speed limit was 55 mph. So its not because ST tires are made in china or everyone was speeding that had issues.

From the time I first started posting on this forum, which many years ago and with my original user name, nothing much has changed with ST tires. Except maybe Sailun relabeling their S637 from a LT to a ST tire. So we know there is at least one quality ST without a history of failure. Chris

Nope, not at all. But if you typically drive 70 mph down a gravel road, come to a skidding stop, do a rubber-wrenching U-turn to jackknife into a spot.... Let's just say YOUR tires are gonna wear out long before mine.

Blaming everything on the manufacturer is a typical response because it's easier than taking ownership of possibly poor driving habits.

BTW - I forgot to add hauling 1000# over the tire's limit. But, that's for another thread.

Yes, but see, I can boil this all down to a couple of simple sentences:

I expect my trailer tires to follow along over the same things my truck tires do, and be just as reliable.

So, I uses LT tires also on my trailer....problems solved.

Of course spending more $$ on the better tires will help because you are getting a BETTER TIRE to withhold all of the above. The other option is to just stop doing most of the above and run the stock tires..

....ok, so let's see here, to safely run a ST tire I need to apparently drive slowly only on cool days, on smooth terrain, I can't park the trailer, I must avoid 90 degree turns.....

.....hmmm....yeah, let me think on that a while.....:)

I had no problem doing it.

I can do it, but after the first 15 minutes or so, I do tend to get dizzy.

I used Towmax tires on our old Sprinter travel trailer for 6 years, 10,000 miles and didn't have an issue. I visually inspected them every time I checked them for air and once I started noticing ply separation on one tire, I replaced them all with Maxis.

I am of the opinion that ALL ST rated tires are of inherently poor construction and need to be watched carefully.

My decision has been simply to replace them with a higher quality tire ( LT ). As Forrest Gump said.....that's good, that's one less thing...

Please post the conflicting reports.

The Tow Master E rated tires that I had a blowout were carrying ~1950 lbs each. I had my trailer weighed wheel by wheel so I know what the weights were.

Also have a TPMS and kept the PSI at 80.

On edit: I'm talking about my 05 Savoy that had a GVWR of 10K, not my DRV 🙂

I don't think I hit anything. It's the rear tire so there are two tires in front of it. Seems they would of been damaged also. I was on the interstate going 65mph. It was 5:00 pm traffic and happened so quick its hard to tell.

I experienced a blowout and replaced all 4 tires. I kept the opposite side, opposite axle as a spare.

After arriving home I decided to replace all tires with LT's. I put all 5 tires along side the house and posted them for sale on Craigslist. A few weeks later this is what the spare looked like. The only thing I ran over was the sidewalk next to the garage.

No need to post anything to prove how my statement is true.

Common sense however, tells me that your statement is not true.

ALL reports of bad blowouts (what's a bad blowout vs a good one?) have been E rated that were run near max? You analyzed every single one of them? And they ALL were near max? No you didn't and no there were all not near max.

I had a blowout on an E rated one and I was not at max. So essentially because I reported one (that you must have missed since you reviewed all of them) and my failure makes your statement false.

And I have what I suspect is a pretry fairly common sized 5th wheel considering there are so many Montannas on the road.... A similarly sized 14.5K or 15K GVWR trailer.... I have 10,300 lbs on my trailer axles.... Well below the 14,080 overall tire capacity.

I have had GY marathons on 4 different RV's and never had a issue. I know others have had issues with them.
