Experience, knowledge & opinions needed

[Semper Fi]

Good morning all,

We Purchased 2015 39MB late fall 2019. The unit still has the original tires in service. The tires are Goodyear G14 RST 14 ply , Lt 235 / 85 / R16. Total road miles on these tires is between 400 - 500 miles. The life of this Redwood up to 2019 has been to haul from storage barn 20 miles to RV park & back to storage in the fall.
While at the Rv park the tires were always covered per the previous owner. I looked the tires over very good and did not spot any sidewall or between the tread cracks. No sign of any type of failure. We took several short trips this past summer without any problems.
Our plan is to head south next winter. Probably 2500 Mile round trip. At this point in time the tires will be 7 years old.
The big question is, even though they look in great shape, should I trust a 7 year old tire on a long trip. I’ve read on line where rv’ers have used these same tires up to 8 & 9 years before change out.

Being a first time RV owner, any and all opinions / suggestions would be much appreciated.

Thanks, Randy & Karyn

Buy new tires and a TPMS system. Blowouts can be expensive.

I agree!
Check out Sailun tires as replacements though, in my opinion every bit as good as the GY at much less inflated price. You'll find a lot of folks on here running them with good luck.

The issue is sidewalls get week from sitting in 1 spot for so long... Thats why so many change tires every 4-5 years
... its usually NOT due to miles....

All of those steel belts in there holding the weight in 1 position for a long duration


buy new and enjoy the ride !

For not much more then the price of the good year 614 tires you can put a set of 17.5" wheels and Sailun 637 tires . and never have to think about tires other then pressure and age out of service. The 17.5 tires depending on the size and load range can hold 4800lbs . I am running 215/75/17.5 tires on mine and would say that the 235/75/17.5 tire would fit also and they are rated at 75 mph.
The Sailun 637 235/80/ 16" tire has a weight rating of 4400 lbs. and is a very heavy duty steel belted radial tire.

We have a '16 39MB and know the early ones were faily heavy and the G614s are marginal for that unit. Were running the 17.5 GY G114, granted we put plenty of miles on them, but was hoping for 5 years from them only made 4 1/2 years before one blew. We were lucky, only took on the plastic fender skirt. Installed the Sailuns at that rally and been fine since.

The life span on tires now is 6 years. Replace them now!

I have a 2016 39MB with the westlake tires, I have always ran my tire PSI at 100. I have not had any problems with them. So I think that the reason all the tire that i see here that are blowing out and damaging the rv is because the drive is running the PSI at max. You need to remember that when driving the HWY. the tires will heat up 5 to 10 PSI.

new tires every 3-4 years no matter what miles they have on them

[dave737]

Another vote for the Sailun 17.5 and wheel package, and TPMS.

[FTWANNABEES]

I agree with Sailuns as well.

[FTWANNABEES]

Get new tires. Sailuns are great!

A blow out at 65 mph cost me $3,500 in repairs in 2016. I seen it blow and got stopped immediately but the tire came apart anyway and took out a section of the dinning area above the wheel well and tore off trim from the door and side. I will not run tires over 3 years old from the manufacturing date! Although my unit was only two years old.....the tires were five years old per the Mfg. date.

Thanks all for the reply’s. Great info & suggestions. One thing for sure, looks like l’ll be putting on new tires this spring.
Thanks again, Randy & Karyn

I have a 2013 Redwood. Our Goodyear tires looked great. Stored inside most of the year. We had two blow outs within a year. Tire dealership said the tread was separating on a third tire. We replaced all of them.

I don't know if this is allowed or if it is acceptable practice, but there is another recent post on redwoodrvowners forum that has some interesting tire information:

Cant figure out how to edit, but I don't think the previous link address works. Try this to the other forum post on tires:

I give up. Here is the first post in the thread:

Posting this for newer members who may be searching for good tire information.

The two preferred brands for our Redwoods are Sailun S637 (G- or H-rated), Goodyear G614 (16” G-rated), or Goodyear G114 (17.5” H-rated).

If you have Westlakes, they usually provide adequate service for about 2 years from the manufacturing date, not the date you bought the trailer. They have a history of blowing out or throwing tread with no warning, regardless of mileage, pressure, care or use. It took between two and three years in service before Westlakes began having a lot of problems.

If you have Goodrides, they replaced the Westlakes on new Redwoods in 2019, so you are the guinea pigs. They have not been in use long enough to know if they will hold up but so far not looking promising. There is at least one that blew on a 2019 with less than 3,000 miles.

Of course, use a TPMS. But it will not help you on a Westlake (and probably Goodride) failure. It happens instantly with no warning.

Here is the difference between Sailun and Goodyear:

You will be hard-pressed to find any documented failure of a Sailun caused by the tire. They simply don’t exist, and the tire has been in use millions and millions of miles on thousands of heavy 5th wheels. Even those who experience a failure due to road hazard have found the casing usually stays in place, minimizing any damage.

Goodyear, on the other hand, has many documented blowouts of both the G614 and G114. But so far, Goodyear has been good about reimbursing owners for damage to the trailer sidewall.

All the above are facts.

My opinion is don't take your chances. Even on a brand new rig, one of the first things you should do is replace your tires with a proven brand and avoid the downtime, disappointment, and damage that a blowout will cause.
