Unfortunately, going with a larger tire isn't going to gain you the height increase you're looking for.

Going with the largest size trailer wheel we offer, which is a 17.5 inch would only lift your trailer by 3/4 of an inch or so, compared to the 16 inch wheels you're using now.

There are a few other ways to increase the ride height of your trailer, which you can read about in the article I've linked for you.

If your leaf springs are currently mounted under the axle, you can use an over-under kit such as part # K71-384-00 for 2-3/8 inch diameter axle tubes or # K71-385-00 for 3 inch diameter axle tubes. These kits allow you to relocate the leaf spring pack to the top of the axle tube which will gain you a ride height increase equivalent to the diameter of the axle tube plus the height of the spring pack.

Adding taller spring hangers could also help achieve the height gain you're wanting. You'd need to increase the front, center and the rear hanger by an equal amount so as not to change the suspension geometry. I'll link to our selection of spring hangers.

It really just depends on what you are looking to get out of the bushings. Bronze bushings, like part #K71-291-00, will last longer but are more noisy and it is recommended to use wet bolts like part #126B2 to keep them lubricated. Nylon bushings,…

Answer 8

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

Do you by any chance mean 235/80-16 and 235/85-16? Because there isn't a 275 trailer tire size that I have seen. If so then the widths are the same between the two 235 sizes. The difference is overall diameter. The 235/80-16 is 30.9 inches in…
