Is this just the trailer axle weight or total gross truck and trailer?
8600 is a lot of weight on what I'm assuming is a 235/75/15 x 4. If it was a 1/2 ton pickup you would have to have 3500 lbs. in the box to weigh that and you'd be surprised to get out of the driveway.
In any case I'd be running the highest load rated LT tire I could get for that size that had a highway speed rating of at least 75 mph.
Trailer tires are for utility trailers that never leave the farm.
Kevin [/quote]The tires are 225x75x15 ST E rated for 2830 lbs. per tire, the axle weights is what I posted so it has 11320 Lbs. load carrying abilty on all four tires and 8490 lbs. on three tires
the truck weighs a tad over 7600 Lbs with me in it with a half of tank of diesel and the trailer hooked up going down the road to the races with the old duster in it. My current S/P car weighs right at 1000 Lbs. less than the Duster did
I am going to reweigh it again empty and then with the new race car in it so I have current weight on the trailer going down the road.
I dug through my tire receipts for the truck and trailer and the tires that blew out may have been over ten years old
I will buy the covers and use them from now on
Hopefully this post will help someone else from repeating my mistake, I honestly thought that the tires on the passenger where less than three years old
Thanks to all for your help and comments
