Goodyear Wranglers on 2017 Bambi Sport 22FB

Hi AS Team!

Recently, I reached out to Airstream in Jackson to see if they could endorse me putting on the same model of Goodyear Wrangler Duratrac tires onto my 2017 Bambi Sport 22FB as can be seen on the new 2020 Basecamp 20X. I inquired as to whether the more aggressive tread might cause any structural issues. Jackson gave me the go ahead to proceed. So now, along with my 3" Torklift lift, I have the more aggressive tires to help me access a few additional places out here in the Northwest.

Anyway, it changes the aesthetic somewhat, and I have a feeling from that perspective alone, there are going to be some robust opinions in favor of the stock tires. I am sure my reasonable self would do better to respect those opinions because the classic AS look holds a significant amount of sway in my own heart as well.

Before I made this choice, I looked and looked to see if there were any images online that would give me an idea of what the final product might look like. I could find none, but I had a strong feeling I would like the tires from a practical perspective and aesthetically as well (Yes, I could have used photoshop, but what fun would that have been?).

For those that have thought about it, you now have an actual model to help you in the decision process. For those that would never think of it, you now have an actual model to support that perspective as well.

But for me, I think the switch looks and drives better than I had envisioned and/or expected.

Enjoy...or don't

For once I disagree with Bob. I think you made a great choice. I know a retired Goodyear tire designer who ran Wranglers on his trailer during the Marathon era. They worked good. I have mentally not quite gotten over the bad period for ST tires. Let us know how they work out for you as time progresses.

We have the Goodyear Endurance tires on our 2018 22FB Sport. The Wranglers look rugged & ready, and kind of look like something that would be conducive for the terrain that we deal with in Wyoming. Will be watching and waiting to hear how these perform!

I like the look, but...

There are plenty of threads on ST vs LT tire here. Have you done any research? Calling someone at Jackson AS and getting an OK, does not sound like research to me. We are lucky to have a couple tire engineers here on the forum.

Perhaps Roger Marble - (Tireguy9) https://www.rvtiresafety.net/search/label/Trailers

Or Barry - (CapriRacer) http://www.barrystiretech.com/sttires.html

It sounds a lot like you based your decision on new tires because of there "LOOKS". Since you have already made your choice. I guess it really doesn't matter. Keep us posted on how they perform for you over time. Good luck!

Stay off the gravel and pea stone resurfaced highways. No telling where those tires will toss the little buggers.
But I have to admit, as trends go, pretty good looking!

Excellent point! I will endeavor to review my mud flap situation and hopefully mitigate some of those concerns.

I would be lying if I didn't say that some percentage of my choice in tires (significant) included aethetics. Probably why I paid the premium for an Airstream...aesthetics...you caught me! I lbought my Airstream because it looked so good!!!

But I also frequently traverse a rugged path to a gorgeous undeveloped property I recently purchased that the tires and lift have helped me to more easily clear obstacles that might otherwise be detrimental to the under carriage.

So I probably under sold the practical value.

Did any of the engineers you mentioned make any comments about Airstreams decision to use these same tires on their Basecamp 20X?

I chose GY Wranglers also at the start of our build. They had the specs desired and I liked the idea of having a Kevlar ply. Four years of towing no problems. Time to change out due to age, 2013 date stamp.

You wonít be alone for long. I plan to do something similar in another year or so when itís time to replace the tires on my 2019 Sport 22. The 3Ē lift gives the space and I too want more dirt/desert road confidence. Looks great too.

It looks like you kept the original 15Ē wheels. What size did you use, and what was the load rating?

Be careful! It looks like the dry weight of your trailer is 3,600 lbs and the GVWR is 4,500 lbs.

Just the trailer and full holding tanks plus propane will exceed the tires combined maximum weight rating. That is before putting in the coffee pot, a can of beans, or even a blanket and pillow.

Just sayin

yes it looks so cool but yes there is always a but somewhere in this.. but it cuts too close like Batman warns. the wheel well is not big enough, once there is a blow out, the wheel well and a panel or two will be severely damaged. I admit it looks so cool. I like the white lettering tires. if you insist to keep the Wrangler tires, at least paint the letters white... will look super cool!

The maximum load rating of the tires must exceed the Gross Axle Weight stamped on the axle. I think that is a pretty universal DOT requirement. The axle wt rating will be less than the GVWR for the trailer by the tongue weight. Looks like you are going to be close but maybe not quite enough tire rating to be legal. I hope you checked that.

Hi Dennis

The load on the Endurance tires is 2150, so that also puts you below the GVW based upon your calculations. However, the trailer also distributes its weight at a third point as well.

The Basecamp 20X has a GVW of 4300 and these are the same tires.

But I take your point. One should ne cognizant to travel within the load ratings and make safety a priority.

What does the trailer say the axle weight is? The is the number the tire rating needs to exceed. Since it is a LT tire it does not need to be derated the 10% from the stamped max load.

The load rating of my Goodyear Endurance ST225/75R15 load range E, are 2,830 at 80 psi.

The third point of contact on the trailer (the hitch) does not distribute the weight off of the trailer tires. A WD hitch with distribute the weight off the rear axle of the TV to the front axle of the TV. It will not distribute weight from the trailer tires...

"My calculation" was from your info numbers. Trailer Unit Base Weight (w/LP & "w/o" options, water & cargo) (lbs.) 3,634. Gross Vehicle Weight Rating (lbs.) 4,500 lbs. Your Tire rating: LT235/75R15
Load 1985lbs. 1985x2 = (3970lbs) weight capacity

Holding tank capacities: fresh 20gal, black 18gal, gray 24gal. 62 gallons total at 8.34 lbs per gallon = 517.08 + 3634 = (4151.08lbs)

With nothing else in the trailer you are over the weight rating of your tires by 181.08. Now add hundreds of pounds of cargo, cloths, food, gear, etc.

You do the math. I was trying to help, not stroke your ego. Be safe.
