Tire change for my 25FB

[runningjill]

What do I need to consider when it comes to changing my 15 inch Goodyear tires to 16 inch Michelin tires? Besides rims and tires what other items are required to make the transformation from Goodyear marathon two Michelin LTX tires?

New steel valve stems, new high quality lug nuts, and a good balance of new tires and rims. Some add a TPMS, we don't but are assured by the high reliability record of these tires on Airstreams. Some add Centramatic balancers, we don't. They are a stiff tire and at 80 PSI maximum pressure for them they can be a rough ride for your Airstream. Some run them anywhere from 65 to 80 psi, we run them about 68 psi.

We also have a 2017 FC with 15" GYM. I plan to move to Michelin after we've put some miles on our GYM's but I see no reason to toss them until then. I'd also like to stay with 15" for that added flexibility in the sidewalls but am happy to be persuaded if there are good reasons to upgrade to 16".

I bought the identical Eddie Bauer AS setup. The wheel lug pattern- check, You want Load Range E- careful there are two different tires of the same name Passenger LTX and Metric LTX you want Load range E (metric), The reason for 16" more than anything is that it opens up the choices for tires. There are very few 15" tire choices. Make sure they are balanced. I ended up having to go to a special truck place to have them load balanced because Costco, where I bought them, did not have the correct fitting for the Sendel trailer wheel to use their spin balancer. I have learned that many places do not bother balancing trailer tires.

We ordered the upgrade from the factory on our FC25, 16" wheels with Michelins LTX and very happy ($1700 including spare). However they put the crappy lugs with the covers instead of quality lugs. What did you use and what's the correct size? Thanks!

ORDER from Performance Plus Tire CTR, get the tires and rims (T0-3 Sendel) & Gorilla lug nuts. Shipping is free and NO SALES TAX, they will put everything together for you.

I took them to Big-O tire center and they change them out for $50.

Don't forget a spare tire, and they give you the road hazard also. FIVE TIRES & RIMS $1600.

Why do you want to change? I've been running GYM's for many years now and don't plan to run anything else. Of course, I don't plan on exceeding the 65mph speed limit either.

Don't forget that you also want new air in the new tires. I never reuse the old air, there have been too many problems with the old air.

[PeterKV]

Being an old fart I resent the old air comment

[ShinyPete]

No no no air is no good, you need Nitrogen @ $12 per tire. Heaven knows 78% nitrogen air from a compressor isn't good enough. 😬

Hey, sorry I couldn't resist............my smart alec gene kicked in….......

I ordered LT Michelins mounted on Ultra wheels from Tire Rack. They came with the correct and very nice solid lug nuts (which I am not using, see below). Six months ago Ultra was the only aluminum trailer wheel Tire Rack offered. I like the whole package and they always do an excellent balance job. The Ultra hub caps are plastic and attach from the outside with 1/4x20 cap screws--this facilitates a very sanitary and strong odometer attachment if your interested in that.

I switched to McGard 64010 nuts a few years ago and I'm still using them. $12.99 per four from Amazon.
