Trailer Tire Notes-Balancing Boo-Boo, Maybe?

This evening I jacked and blocked up the boat trailer, and removed the tires (14 in., radials).

Since this is a new boat and trailer, I needed to go thru the exercise for several reasons.

First, I needed to figure out what combo of jack and lumber needed to safely raise and support the trailer in the event of a roadside flat or a more serious problem. This is an Aluminum I-Beam trailer, and I want to only use a jack under the galvanized steel axle. This is going to require a 'low' jack.

Second, I need to grease the Super Lube Spindle while spinning the tires. FWIW, after quite a bit of research, I'm going to standardize on one grease for all of my trailer wheel bearings, Kendall, L-427, Super Blu Grease for Trailer Bearings (High Temp, High Pressure). This grease came highly recommended by a couple of marine mechanics (Lake Cumberland area) and was discussed at length with Tech Support at ConocoPhilips (owns Kendall) for higher speeds and heavier trailers, including boat trailers.

Now, for my 'Maybe a Boo-Boo', I was going to have the tires (and spare) balanced tomorrow since I already had the trailer axle blocked up. Loaded up the tires when it hit me, This trailer has been sitting for 2 weeks (parked on grass).

I'm concerned about 'flat' spots from sitting affecting the tire balance.

What say the Pros here?

My thoughts are to put the tires back on and run the trailer up the road, then immediately remove the tires. Due to the aluminum I-Beams, I really don't want the tire shop taking the tires off.

Thanks in advance,

Fred
  • Just got back, the shop 'spin' balanced versus the old school service station 'bubble' balance.

    I'm not sure what to think, the tech said I had 1 decent rim, 1 so-so, and 1 very poor. He told me that the rims were not real true, the worst acted as if bent. These are brand new, less than 800 mi.

    I measure the length of the weights, so to give you folks a sense of the situation,

    tire 1----3 3/4" inside, 5" outside

    tire 2----4 1/2" inside, 1 1/4" outside

    tire 3----3 1/2" inside, 1 1/2" outside


    Tires are Made in China, Karrier, ST205/75R14, LR C, 1760# at 50psi.

    Rims are galvanized steel, make unknown.

    I've been watching here long enough to plan on buying a set of Maxxis before any long trips(KY to Fl,ect,), but based on what I've got, I may need a set of 'quality' rims, too. Upgrading to 15" is also a thought.

    Suggestions? Any comment on the Kendall 'Super Blu' grease?

    Of all the things to worry about this is not one of them.


    X2. Especially if they are radials but even if they aren't, the flat spot goes away after a few miles.
