I have a 1999 Osprey 200 that the manual says weighs 2300 lbs with a 115 outboard. I just installed a 130hp ETEC that they say weighs 405 lbs, or 60 lbs more, than the 115 so going by that, I figure the boat and motor now weigh somewhere around 2360 lbs. Does that sound right?
I have added a T-top at 100 lbs and four series 27 batteries at 63 lbs each for 252 lbs,for a toal of 352 lbs.
A full 45-gallon tank at 7 lbs per gallon adds 315 lbs.
That's 3027 lbs. With gear, I'm guessing the boat, motor, and a full fuel tank weigh perhaps 3075-3100 lbs. Does that sound right?
My single-axle aluminum Continental trailer has a nearly new 3500 lb rated axle and matching springs, with a pair of Kenda Loadstar K550 ST 205/75 tires with a Load C rating. The tires read that they have a capacity of 1760 lbs, which I assume means each, for a combined capacity of 3520 lbs.
The tires are three years old, have good tread, but the insides of each tire are wearing faster than the outside.
I had them reversed on the rims to put the more worn sides out and the less worn sides in, to try to get a little extra life out of them.
A new tandem-axle trailer isn't an option right now.
Question: It's probably about time to buy new tires. Should I consider upgraded/higher capacity tires of some kind?

You didn't say if those are 14 or 15" wheels or if they are radials or not.
I would definitely go with radials. They run a lot cooler than bias ply tires and there is very little difference in price.
Your first option is to go to a load range D tire.
If you have 15" wheels you can also go to a 225R75D15 and those will be well above 2000 lbs each.
The 225 is the width in mm. So the 225s are 20 mm wider. Which is less than an inch.
I recently bought some 225R75-15 tires from Discount Tire and their prices were reasonable, I think about $89 each, and they were load range E, which IMO is even better.
