A different solution to tires

[farnik78]

There’s a company in Hot Springs South Dakota called Boar Wheels. If your trailer has the bigger 235 16 inch wheels they make a 19.5 inch wheel that fits the bolt pattern on your trailer and you can then mount a low profile low boy semi trailer tire. This will have the same outside diameter of the 235 but now you have a much more reliable and durable tire and your chances of a blow out go down dramatically. The amount of side wall flex will also be reduced making your towing experience much more enjoyable.

The initial cost is kind of high, but once you have the wheels the cost of the tires going forward isn’t much higher than the 235 16s. You won’t have to replace your tires as often so overall it’s a good investment. I will need new tires next year and plan on investing in these.

A while ago there was also another tread on this. It make sense al long as the circumference is increased. Lower rolling resistance means cooler operating temperature.

IMO, installing a set of all-steel (tread and sidewall are steel belted) G-rated, 235/85/16 or 235/80/16 tires might be an alternate option to consider. Sailun, Gladiator, and Hartland (America/Discount Tire housebrand) make some all-steel versions. An all-steel, G-rated 235/85/16 trailer tire can weigh as much as 15-25 lbs. more than the E-rated trailer tire of the same size--pretty substantial.

On our last trailer we were able to purchase a set of 4, 235/85/16 all-steel, Hartlands (rebranded Gladiators) for less than $700 out the door, mounted and balanced.

You do hear reports of regular (non-steel sidewalls), G-rated tires failing occasionally, but it's very rare that you hear of an all-steel, G-rated version failing.
