It doesn't take too long and will definitely make a difference minimizing tire wear. I have found that very few shops will align a trailer and I don't know what is involved with fancier or newer rigs.

I was going through tires every three years until I upgraded to a 3500 lb axle vs the 1500 that came on the Bear trailer. Cost about $120 and shipped to my house. Took about an hour to install. 1652 G3 side console.

Lots of good information here...My Skeeter uses an odd wheel/radial tire size that is hard to locate.Last few sets bought from an outfit called etrailer. They have a huge selection of every size known to man and ship at reasonable cost....Might take a look

Put a set on today , hope they get the job done .

If I had a large boat I would insist on " d" rated tires. Wan't weigh 800 lbs. with me in it .

C rated tires will work for coach, he doesn't like to drive far to fish.

Been running 2 ply, B rated non radials . My boat weight is half of the possible carry weight . Figure these radials will work fine .

On thing I came across is age of tires. I got some for my duck boat not long ago and they where 3 years old they where trying to sell me. I made the take them back off and get me some newer one’sb

I just put on 2 Carlisle st17580r13 on my boat trailer. D rated 8 ply. Max pressure says 65. Should i run max pressure all the time? I know 50 is the common but this tire says 65 to allow for max weight but my boat is not near max weight.
