Same tires on truck

[Joeb]

I am looking at getting all new tires for a 1989 Excella 1000 29' and my 2001 Chevy Silverado 1500 4x4.

I am thinking of getting Michelin 235/75R15 LTX M/S tires for the Airstream. The wheel has a 6 lug pattern at 5.5". The diameter is 28.88.

Then on my truck it looks like I can fit a 235/70R16 LTX M/S.
The wheel has a 6 lug pattern at 5.5". The diameter is 28.95.

Then if this works I can have 1 spare on the truck that rotates in and out and it should be okay to use on the airstream I would think for a spare as well.

Anyone have any thoughts or concerns?

You should run only trailer rated tires on your Airstream. They will have ST on the sidewall

I am seeing a lot of airstream owners using the Michelins with no problems as long as the load rating is high enough and these are at 2271 each and my airstrea is at 6800 lbs

Michelen LTX is a good tire for trailers and is put on by AS factory for Tommy lines I believe.

Why not got to 16” wheels on your AS then you have same all around?

Oh boy....before we go down this road, use the search function. You have a lot of reading to do.

I thought of that, then all I would do is get new rims or wheels for my Airstream and sell the 15's. I am still making sure I can use the 235/70r16's on the truck. They call for a 245/75r16 but the one I can use for both would be smaller on the truck and I am trying to find out if I can use them.

[DBinSD]

Thats what I did, waiting till snow is gone to put them on then sell the original wheels.
I have read many people doing that with excellent results.
Good luck !

I have those tires on my trailer for several years and over 50K miles. I could not be more pleased with a tire.

Check the offset on your truck wheels, Airstream uses 0 offset.

Where can I find this?
I found a website with the offset and it was 35 positive so does that mean I can't use a wheel from my truck on the airstream?

[wkerfoot]

Joeb,

I believe that this means that the truck wheels and therefore the tires will set 35 MM farther out from the brake hub. This may make the outside of the tire rub on the wheel well near the outside of the trailer. Someone with better information can certainly chime in.

That is correct. Offset must be the same.

My post may have mislead you. I have 16” Sendel wheels for the trailer. I also have 16” on the truck but, they do not interchange.

[GM Airstream]

ahhh... yes... I did the same thing... went to mich tires... and never looked back... they are the 16 inch... got the rims from sendel... same rim pattern... so they match the alcoa rims on the PU... but the PU has 8 lug... while the AS has 6...

I actually found that the orginal wheels and tires were bigger in dia but narrower in width than the mic tires... just check the tire and all so that you have at least 1 inch clearance all the way around... you don't want the tire coming in contact with the plastic liner... so you want to run the tires , one at a time, up on blocks so they go all the way up... and then check.. for clearance...

Oh and larger rims also meant that the trailer sits a little higher so you have to adjust the hitch...
Also the the tire pressure needs to be lowered... as the plys of the tire also adds to the sidewall strength... You go by the wt load vs tire pressure for the mich chart...
Trailer rides sooo much better that way...
I got the new rims from back east... be careful as some of the new knockoffs are china made and not DOT rated...
I called dexter down south.. and found out that you can change the spindle/break drum etc... and go to the 8 lug now... and exchange it for the AS 6 lug items... but, in talking to the engineer.. he said that the chevy 6 lug spindle is more than strong enough.. for the trailer wt... as the cost to change the spindle and drum is about 300 each... then again you could use the PU spare .... then again... the trailer also has the spot up front for a spare too.. so two are better than just one.. thing... If you go north to AK...
Then again I haven't heard many having problems with the Mitch tires and new rims...

Also just for info... the alu rims help to get rid of tire heat...et al.... which is a bonus... grin...
Change over to 16's and its cheaper and sooooo much better.. and as they say... once you change.. you will never go back... grin..

I have had Michelin 235/75 15" on my 28' for 4 years with 15 - 20,000 miles on them and they are great, but, I am well under their load rating.

Definitely check the offset on the wheels. The easiest way might be to try one of your existing tow vehicle wheels on the Airstream and physically check for clearance issues to see if it will work. I researched factory wheels online and found that auto and truck wheels can be offset as much as 2" or more. Wheel widths may also be wider as well.

My Argosy originally came with steel wagon spoke wheels and those were offset to the outside about 1". When I had the Michelins remounted on a set of 15" 2008 OEM 0 offset alloy wheels I had to add 1/4" spacers to prevent the tires rubbing on the inside.

I think there are more issues with the wheels than tires.

You would want the truck wheels rated to take the load as well. Airstream uses wheels rated at 2500+ pounds.

If you are not mixing truck and trailer wheels and just SHARING the spare, that may work because it isn't a continuous use wheel and tire. If you are mixing trailer and truck wheels in a rotation schedule you will have to make sure all of the tires and all of the wheels conform to requirements of both vehicles.

The goal is to save some space and expense. I get that. And to make all of the tires and wheels conform to both vehicles may generate more expense in the short run and be a compromise should the unexpected occur.

And in the extremely rare event of more than one flat tire, a single spare would greatly slow your travels. Unfortunately I have had that experience. It didn't totally wreck the vacation as I was traveling with a group. However it did add level of excitement that I could have lived without.

Good Luck.

OK, before we go too much further, we need to establish what kind of tires are on the truck.

It sounds like you have P235/70R16's - and that kind of makes this idea almost a non-starter. There is so much incompatibility between the truck and the trailer, that I don't think you can get there from here.

So just to be sure: Check your vehicle tire placard on the truck. It should be on the driver's door post. We will need the tire size listed there (including the letters!) and what inflation pressure the truck calls for.

And then the same info on the trailer.
