1 set of tires that was 2 year old, the tread split and seperated from the base plys
the next set split down the center on a blow out. 1 set was a carlist the other
was a load star. thanks for any help you can give me

So; what size, what is the weight of the boat plus you are towing, what air pressure are you using? More information is the key for getting help, you can never give to much.

Depending on where the tire is coming apart, it might be a bolt in the fender. A weak spring would allow contact. Check the underside of the fender for rub marks.

If you have 8 inch tires, even with a 4 lug drum, you can buy a twelve inch wheel and tire. Less revolutions is less heat and you can probably get a higher ply rating as well. Then run it down the road and see of the bearings are heating up the wheel. Most problems are not isolated.

the size tire is 6.90x9 and the boat is a 1987 bayliner capri 17.6 I think it's about 2700lb It's on the original escort trailer.
the air pressures was set by Pete's tires

High-speed Tubeless Trailer Tire
This heavy-duty tire is for use in high-speed applications. Tubeless tire measures 6.90 x 9; 6-ply rating; 1,120 lb. capacity.

If this is the tire type, it would appear you are over loading them. And they appear to require around 60lbs of pressure.

Go to a larger tire that is rated for the load you are subjecting it to, at least 1370 lbs.

Geez dude: 1120# capacity. Two tires = 2240 pounds maximum Gross Vehicle Weight. You say the boat is 2700#. The trailer also sits on those tires so add another 500#. Do you get the idea the tires are under just a LITTLE stress -- by about 1000# plus any gear, gas, coolers and other stuff you stuff into the boat.

A 2000 Capri 1750DX weighs 2670lbs with the trailer and base engine. 2140lbs without the trailer. You can get a lot of info on your boat at www.bayliner.com under "visit the showroom", "older models"

This was posted on another thread, which engine package do you have? You might not be overweighted just close to capacity. First thing you need to do is to verify the boat and trailer weight, not just a guess. The weight capacity will be printed on the sidewall of each tire. Without correct info your guess is worth as much as anyone else's.

An '87 weighs considerably less than a '00: 1780# for the I/O version, 1475 for the outboard version (with original 85 HP Force motor). These are dry weights; the sales brochure says "total package weight," but those numbers seem too low to include the trailer.

Re: trailer tire keeps splitting down the middle

Some of the early escort trailers were very light, I remember I could pick the one I had under my old 16 and move it in the parking stall (not with the boat). The OP must be more specific as to what he has. I would suspect a bent axle or loose bearings. This would make the tires not track correctly and overheat the tires cosing failure. Running the tires under inflated could have same effect.

Re: trailer tire keeps splitting down the middle

+1 for Bob's Garage. For peace of mind, I always buy tires that are way over-rated for my boat/trailer (scissor-type for a pontoon). Don't ruin a great boating day with a blowout caused by cheap, under-rated tires.
