4.80X12 Trailer Tires
 

My trailer has 2 4.80 X 12 tires its a 2 place ATV (sideway's loader) ,lets' see the trailer is ca 300# ,each ATV is ca 600# so its a combined 1500# unit,now here comes the question: each tire is a 2 ply 790# max weight at 60# airpressure!!!!

Is it save to haul that trailer around on these tires?

(previous owner said its a 2 place/ i didn't feel good with 2 Atv's so all i used is hauling 1 ATV!)

Are there tires available in this size which could support 2 ATV'S?

I wouldn't like to push it to the limit like that. Does the trailer have a sticker that says how much it can hold? It might be a lot less that the what the tires say. If I put over 30 pounds of air in mine it eats the middle off my tires, so I can't haul the maximum that my trailer or tires said.

Look at the make of tire, then haul out the yellow pages and find a tire dealer. Sounds like you are running close to the line..You can probably buy tires with a heavier weight rating but they might be special order.

I have trailer (4x7) with same size tires. There is a size bigger (1" taller) you can get and I've been thinking about going to those. As said, read the capacity ratings.

My tires are the same diameter and 1/2" wider and IIRC can take up to 80 PSI. It's buried in the snow so I can't see what it says but I think they can handle more weight. It would be worth checking into. Since they fit the same wheels it would be cheaper than buying a larger diameter wheel and tire.

Also, of equal importance...not all wheels are created the same ;)

What I am getting at is to make sure what the wheels (rims) are rated at to know what load rating or PSI tires can safely be used.
