New Tires

[pjberny5]

Know this might start a major debate but I am looking at replacing the OEM tires on my Bighorn 3260EL. It currently has TOW Max STR 235/80R-16 E rated tires and after just a year and only about 7000 miles noticed some bubbles forming on the inside side wall on two of the tires. I'm very anal about inspecting and checking the air pressure and torque each time before we move. Not sure if this is just bad luck on these particular tires and replacing with the same brand and size or with their ST235/85R-16 would be the best or not. Have researched on the WEB but seem to find good and bad on almost all brands of ST tires.

Would appreciate any recommendations from your experience.

Thanks for all the input. Decided to replace the TOW MAX tires with a set of Saliun S637s. Now I'm dealing with the warranty company to try and get some type of compensation since the tires were still under the one year warranty.

My 2015 Big Country has 7000 lb axles and came with Sailun G rated tires.

I just replaced the Blowmaxx tires on our Bighorn today. New set of Goodyear G614's. It is worth the peace of mind. I considered the Sailun S637's also for the cheaper price, but went with the Goodyears because of availability. Sailuns are available online but not as easy to get if you have a problem on the road. We could not find anybody within 100 miles of our home that even stocked them.

Good Years warranty/road hazard policy is outstanding:)

And many have had to use it for both Marathons and G614's. No one has reported a Sailun failure to date! Chris

X1. Go with the Goodyear G614 E rated. Never had a problem after 10 yrs. and run them at 110psi.

That would be G rated... 🙂

Thanks, before they had the curret G rated tire, i ran E rated:)

Sailun's are not stocked at many places. However many tire retailers can have them in a day.
I chose savings vs. paying almost double to get a stocked tire.

I see you are in KC. "Dob's tire" in Blue Springs installed Sailun S637's for me about 2 years ago. They were in a KC warehouse and they were delivered to the store the same day I bought them. Your rims will handle 110 PSI. It is stamped on the back side of the rim.

I also suggest you visit the "Heartland Owners forum". There is a lot of discussion about tires there.

To say that LR E tires "simply won't work" is absolutely wrong.

They WILL work, but the tire capacity becomes the critical measurement in the suspension load capacity. His 7K axles now have a maximum capacity of 6,048 pounds. Just like those of us with 6K axles.

The lower rated tires are not going to "hurt" the capacity of the axles.

You now have to be very careful about loading the trailer, but that doesn't mean that it "won't work".

I do agree that it doesn't make much sense to reduce the capacity of the suspension, but it could be done without damaging the axles.

Tires are required to at a minimum to meet the GAWR. I posted a link to the reg a while back.

Tire selection under FMVSS No. 120 consists of two elements. With one exception, each vehicle must be equipped with tires that comply with FMVSS No. 119 and the combined load ratings of those tires on each axle of the vehicle must at least equal the gross axle weight rating (GAWR) for that axle. If the certification label lists more than one GAWR-tire combination for the axle, the sum of the tires' maximum load ratings must meet or exceed the GAWR that corresponds to the tires' size designation. If more than one combination is listed, but the size designation of the actual tires on the vehicle is not among those listed, then the sum of the load ratings must meet or exceed the lowest GAWR that does appear.

Just looked up the 5er, (guess I should have done it earlier)...got the impression 5er had 7,000# rated axles on it...if it does, it's over kill with a GVW of only 14,000#....You are correct.....knowing this, I'd have zero problems with putting the RIBS or the R250's on the 5er...For some reason I had the impression that "G's" were on it or required... next time I'll look at the 5er information first...

I guess "IF" the OP wanted to go with G rated tires, the Sailuns' would be a good bet, but would have to make sure rims could take 110 psi.....

Why go through all that when all you have to do is match the tires with the axle rating? One would have to weigh their unit to make sure they only had around 6,000# on each axle...seems like a lot of bother, when in the long run, purchase 16" G rated tires that are "normally" mounted on 7,000# rated axles, (I said, "normally"). The Sailuns can be had at a VERY affordable price....Why not go with something that will give one "Peace of mind" and KNOW you were within the safety specs of the units GVW?

Here is a quote from a member back in April -
"The price seems pretty reasonable for 4 tires shipped to Utah ,the total is 704.44 thats 176.11 per tire plus mounting ,and balancing. they are going to be under 800.00 for the set.
Thats a far cry from a set of Goodyear G614's. "

Cheap alternative for a what look to be a quality tire
