I live in the UK and have an American trailer made from triton trailer components. Unfortunately I cant find any company that ships triton components to the UK so I would like to change the axle , springs , bearings etc to ones available in the UK. What I want to know is how to work out what weight ratings I need.<br /><br />Do I need to Get the Gross Weight of the boat + weight of the trailer and divide by 2 to get the weight on each tyre? If two axles can I divide by 4?<br /><br />Regards<br />Chris

Re: What Tyre Ratings are required.

Generally, you take the weight capacity of the trailer or axle(s), whichever is lower as that is your max capacity, divide that number by two (or 4 for a tandem axle) and make sure your tire capacity is above that. This assumes that your trailer has enough capacity to safely carry the boat on it.<br /><br />For example, my trailer is rated to carry 4800lbs an 2 axles. 4800/4 gives me 1200lbs per tire required. Because of the tire size I need on this trailer, the tires I have actually are rated at 1860 per tire, well above what is necessary. I like a large margin of safety. What size tires are on your current trailer? 205/75-14?

JasonB,<br /><br />Thanks I can't tell you what the size of the tyres are because the boat is near the water. I have tried and cant get the size of tyre over here (carlson tyre). The trailer that came with the boat is a single axle (1900LSR Regal Bowrider) I have never seen a single axle over here on a boat that size so I am trying to work out if I can get the bits to replace the single axle with a UK single axle rated for the correct weight with a safety margin. I suspect I cant and will end up either having to import the parts through a Regal main dealer or convert to twin axles. The costs of getting it through Regal are so much I really want to convert<br /><br />Regards<br /><br />Chris
