Ever since I got this HTT a month ago. I for some reason didn't trust the tires. I looked at them and I didn't see any cracks, the treads were at 8-9/32 so I thought well they are 6 years old perhaps that is it. I will replace them in the spring. We went on three trips (about 600 miles in total) before the end of our season.

Now I'm putting the camper in it's winter spot and getting ready for hibernation. I went around and filled the tires to 50psi. I pulled the cover off the spare to check tire pressure and inspect its condition. What did I find? A bubble in the sidewall. That got me thinking I should inspect all of the MUCH closer.

So I took a MUCH closer look at all 4 of tires on the HTT and wouldn't you know it I found another bubble forming. It was small and I must not have seen it when I first bought it. That was a nasty blowout just waiting to happen.



I guess I will be putting on 4 new ones in the spring.

What is the year of manufacture? It should be imprinted on the tire.


The stamp says 2414 (only mark I could find) and I am guessing that is 2014 which would make sense since that was the actual year of manufacture for the camper. Westlake has a Standard prorated warrantee of 6 years from manufacture or 5 years form date of sale if later than that.

2414 = Manufactured 24th week (June 9-15) of 2014. They are due to be replaced because they are at the end of their life. Some places say trailer tires should be replace after 5-6 years, some say 7.

If my trailer tires were seven years old, I wouldn't hesitate to replace them even if there was nothing that appears to be wrong with them.

If you are putting the trailer into storage, you may as well wait until spring to replace them.


Yeah,
I am going to look around. No time crunch for sure. I may step up to a D rating from a C while Im at it.
I did the math on if I had a flat and the unloaded weight would not exceed the weight rating for C tires (assuming the remaining 3 are ok) but Fully loaded It would exceed that rating.

I also have the challenge to find somewhere that will balance and mount them. called the local RV dealer and they don't do it. Go figure they sell trailer tire not do they mount the blasted things :) )

Dont forget that the tounge weight isnt on the tires, so subtract that from your total weight to see if you need to go up a load size. One load size up is generally ok, too much would not be good.

Thanks,
For this 2015 flagstaff shamrock 233s (HTT) with two axles, I calculated it: The empty weight is 4497lbs with a tongue weight of 458lbs so I calculated 1000lbs per tire.

loaded to the max I have a GVWR of 6600 and guessing 600 tongue weight. So 1500lbs per tire.

if I blew out a tire I was thinking the load would be distributed to the remaining three for the most part so empty 1300lbs on each remaining tire (still within the rating) and loaded 2000lbs. (over the rating of 1760* I believe is the spec). I honestly never expect to hit 2000lbs of cargo but who knows.

I suspect this plays out the similarly with low tire pressure in one tire
If I got it wrong I can save a few bucks ;)

When I replaced tires on our TT I bought tires and wheels at Discount Tire. I had them mounted and balanced before hand, then I took the trailer in and they swapped everything. I was in and out in less than an hour.

I did the same thing at Walmart for tires on the Pup. But I changed the tires myself at the campground.

Good to know. The shops I called around here wont touch camper\trailer tires for some reason. I either have to buy them with rims and mounted or hope I can find a shop to mount them at least. I also called a few RV dealers and they said they don't do tires and recommended a local tire shop but they don't answer their phone or email.

Just looking online The difference in cost is $87 per tire plus mounting if (I can find someone to do it) for just tires or $187 with rims mounted , nitrogen filled and shipped (etrailer.com).
Just seems strange to me.

They dont like to do them because they come in squished. This means they have to block out the tires and set it in the sun and wait for them to heat up before they attempt to put the tire on. Its a hastle for them. My guy does it but now i block out the tire at home for a few days. Its easier to order with rims.

Fyi the load is will not be evenly distributed if you have a blow out. The side with two tires will remain unaffected, and the remaining tire on the side if the blow out will carry double the weight. But it would be a very short period of time while you pull over. I would also suspect you will have more than 600lbs tongue weight fully loaded.

A bad day camping beats a good day at the office
Ordered tires from eTrailer a few years ago, and one had a bubble in the sidewall from the beginning. I shrugged it off... I'm not a "tire guy" and thought it might just be a cosmetic issue. They wouldn't ship me a tire with such an obvious problem, would they?

Had it for a year and it was fine. Then the next year we were driving out to Yellowstone... about 8 hours into the trip, and BOOM. Failed right at the bubble.

Story learned. Bubbles bad lol.

How many other bubble tires have you seen running? Should have been a red flag. Will be now.
