Two place trailer tires

I have a two place trailer with 18.5-8.5-8 tires on it and seems to pull harder than my tandem axle boat trailer. Is there a better tire size to go to that would help the trailer pull easier?

i dont know if it will pull any easier but i put 13 inch tires on they are taller and narrower. I had to make a 2 inch lift to fit them but the bearings turn much slower now and the tires shouldnt wear out as fast.

I have used the 20.5 x 8 -10 for years and have been totally satisfied. In general, more rubber on the road is better. Great handling, wear and mileage. Just love 'em. Carlisle I think but make sure you are getting the ones properly rated for load and speed as some of the china brands are a poor choice. Good spare, jack and a battery powered impact wrench and you're loaded for bear. I even travel with a can of the fix-a-flat.IMG00015-20110409-1829.jpgaaa sled trailer.jpg

I honestly don’t know the answer to that question. But I think the answer is no. I’m not even sure if the Top Cap brand of trailers even remains available these days in that configuration.

you can buy a cover thats made of tarp and metal bows. i've read they pull tuff but i doubt its harder puller than a flat nose enclosed.

I own a tire shop. I converted my trailer from the 20.8/8X10's to a ST145R12. The ST145R12 are a little taller, so make sure you have clearance, or add a spacer between the trailer and the axle. These tires will last 3 to 4 times longer and only cost about 2/3 more. Radial trailer tires have better sidewalls for stability, make sure they have the ST designation on them. Don't by a passenger tire.

I have been pulling a triton 10’ open, with no salt shield and 8” tires, since 1999.

Trips are 1,100 miles round trip, multiple times a year.

If you have a tilt bed trailer, installing taller tires will increase the angle of the deck when tilted, making it more difficult to load.

A few years ago I wanted the fiberglass cap but they were not making them any more.

I have pulled similar trailers with salt shields and they definitely catch more wind and are harder to pull. By this I mean your mpg will drop 1-2 mpg and your truck will downshift more in the wind and hills. This is with a 1/2 ton pickup.

I did this 5 years ago and has worked great!

The effort required to pull a trailer can be affected by various factors, including tire size, load distribution, and trailer design. You might consider upgrading to larger or wider tires with a higher load rating, but it's essential to ensure they fit your trailer properly. Proper maintenance, tire pressure, and regular checks on wheel bearings and suspension also play a significant role in towing ease. Consult a trailer specialist for tailored advice to optimize your trailer's performance.
