Size of wheels and tires

Recommended Posts

Does anyone know the bolt pattern and size on the wheels and tires for a 2022 Malibu dual axle trailer? Going to look into ordering some larger wheels potentially.


Thanks in advance.

Factory 18’s are 18x9, I believe. The bolt pattern is 5x??? (I want to say 5x4.5, but you should validate). I know for sure the wheel offset is +18ish.

The tires are 255/55R18. 

If you don’t have 18’s from the factory, your trailer fenders are too narrow to run the factory sizes I reference above. So you’d have to do some “math” to figure out how to do narrower 18’s that will tuck under your skinny fenders.

Here's a guide to help determine your bolt pattern, I just had to use it last week to determine my bolt pattern on my Boatmate trailer.  It ended up being 5x4.5"

When measuring start with 1" centerline of the first bolt (essentially cutting an inch since not all tape measures are created equal).

 

Word of caution on the 18" tires, you cannot run to just any tire store to get a replacement the same day.  No one near a main interstate from Nashville, TN to West Monroe, LA had one on a Friday when I needed one or two during my 8 hour trip home.  Would have been sometime Monday at the earliest to have one arrive at the tire stores.

Hey @jwl019 Did you get a new ride? You should have hollered as you were driving through.

Hijack off.

Yes sir I did, '16 Ri217!  It was supposed to be a fast trip, but did not turn out that way. Water tested boat on Percy Priest Friday morning, bought boat, then started the long adventure home.

Pics: 5 year old front tire hit fender which caused it to blow 1 hour into the drive.

Trailer had the 15" spare so mounted, hit up 5 tire stores in Huntsville with no luck. Continued rolling on.  I think the smaller spare is what kept it from rubbing the fender.

Not too far from home (near MS/LA border on I-20), rear tire blew and messed up fender and took out a brake line.  Never found any of the 18" tires to replace the 1st when calling around everywhere along the route. Carried on slowly with only the spare and front hub ratchet strapped up with no brakes.

Made it home finally on Saturday.  Monday I ordered tires and installed Tuesday.  Tuesday morning I confirmed axles and brake lines with Boatmate and ordered.

I am pretty sure the bad/failing torsion axle caused the initial tire blow out, but age of tires surely did not help any.  When I started the drive home, I noticed it was a little lower than the rest, but did not look like it would rub. The rough rodes and 70 mph sped the failure up a bit I guess.

I know the difficulty buying 255/55R18s, but have another tire question.  My 2017 Malibu tandem trailer came with OHTSU ST 5000 All Season Steel Belted Radials. I recently had a tire shop refuse to mount an all season radial on my wheel because they said it's not safe and in the event of a blow out they'd be liable.  My confusion is about using radial tires on a boat trailer, is it safe?  Is there something special about the OHTSU tires versus other radial tires that I'm not understanding?  Thanks.

Just as a general rule.  On boat trailers a 5 lug pattern is 5 on 4.5 and a 6 lug is 6 on 5.5

Pretty rare to run across anything else.

While those tires come stock, they aren't proper trailer tires.  Most shops will mount them, not all.

 

Considering the factory and trailer mfg consider them safe, they are probably fine.  But i wouldnt' run any old radial, i'd stick to trailer tires if i switched models.

 

2 Biggest trailer tire tips:  Run a rated PSI (rated max on Trailer tires), and replace every 5 yrs.  They rot before they wear out, tread depth has nothing to do with age.

 

 

Not much help, but my 0.02.

On my car trailers I ran nothing but e rated truck tires.  The trick when you get to the low profile stuff is trying to find something with an adequate load rating.  As for a tire shop not mounting them - you bring them a wheel, how the heck do they know it is for a trailer?  Tell them it is for a streetrod if they are the nosy type.  Can't recall anyone ever asking me what vehicle a wheel was for on a carry in mount.

Thanks for the replies.

I decided to purchase a Firestone Destination LE3.  Same dimensions, load rating and max pressure (50 psi) as the OHTSU ST 5000 that were on trailer originally.  Since it's a spare it may take some time to learn whether this was a good decision.  

I do wish a Malibu representative could explain why Malibu decided to outfit their trailers with anything but readily available and conventional trailer tires (and wheels).  Nothing worse than being 100-miles from home and needing to buy a tire that is not readily available.

My lug-pattern is 5 x 4.5".  For 2023 season I might consider replacing OEM gear with a set of four 16" wheels and tires, something like Trailer King ST235/80R16 E 10-Ply.  Not as sexy looking as the originals, but perhaps more practical for the boat that routinely goes on 50-500 miles trips.

50psi max says that it is likely only a c rated tire, which most stock trailer tires are and they are typically underrated for the actual load of the boat and trailer.  As for the why on 18 inch tires and wheels - customers demand big stupid bling trailer wheels so they provide them. The 15 inch factory combo is the best for towing if only for the range of heavy load rated tires available - just not as pretty.

I fully agree with this.  When my tires hit expiration, i'm selling my fancy wheels and getting black steely's.  I HATE fancy trailer wheels.  Trailers are for function.
