So it is time for me to replace the tires on my trailer for my 22ZX.
The trailer is a Loadmaster, all aluminum, dual axle, all four wheel disc brakes, with hydraulic surge brakes and electrical cut-out for reverse. It is the trailer supplied by Donzi when I bought my boat new in 2006. Even stamped into the frame to say so.
Anyway, it has the original Goodyear Marathon Radial ST205/75 R 14 tires on it. Those are being replaced. Tire Rack has them, and so do a couple others, but I was looking to shop around a little.
Walmart has that size trailer-specific tire already mounted on a shiny new galvanized steel wheel, but they are a brand I have never heard of, and they are NOT radials - they are bias ply. Yes, West Marine has tires and wheels, too. And I am certain my local favorite tire store will be happy to order something for me and mount and balance them.
So my discussion questions are:
Is it OK to change out the four old original radials for the off-the-shelf Walmart "specials" that are Bias Ply or should I stick to just replacing the existing Goodyears specifically with new radials? I actually prefer the radials (in my head), because that is what the factory chose to spec. But I am open to your rebuttals for the cheaper priced bias ply. The radials have really stood up well considering all the miles on them verses the bias ply tires on my 2001 Classic 18 trailer tires which wore out pretty quickly (single axle trailer, no brakes).
Walmart also offers a trailer-specific wheel/tire combo in 15" (verses my current 14"). Any reason I should not go ahead and select the larger diameter wheels? Any benefit? There appears to be ample vertical and horizontal clearance under the fenders for a much taller tire.
If I buy the Goodyear radials again, can I mount them on brand new old-school 14" chromed steel Cragar S/S mags? Will those four wheels be strong enough for trailering a gross load of 5500 lbs? I realize the stupidity of chromed steel wheels in brackish and salt water launchings, but if I hose them down each time I get home will they at least be safe while they get rusty. LOL!
Any other hot ideas?
