replacing 15" tires

I know this is beat to death however I have 225/75r15 tires with a d rating @65psi looking to replace I know every one on here is LT positive however everything I look at in LT doesn't really have a 15" I should say all the ones recommended on here and the ones that do have a higher pressure rating// question is will rim design be able to handle this? also talked to rv dealer where we bought unit and a tire guy both think the new Carlisle USA trail are the way to go?? NEW is what I'm wondering about

    The usa is a bias ply tire 2450lbs load d and weighs 34.6 lbs @ 65 psi
    The radial trial RH is their newer designed radial tire 2830lbs load E weight is 35.2 lbs @ 80 psi.

    Have never used or read about the usa tire so cant comment on it.
    Lol, for that matter havent used the RH tire either but going to give it a try :B

    Not a fan of carlisle but due to price, the benefit of being nowhere near the weight capacity and positive comments from my tire guy will give it a shot.

    thought of going to 16" rims however not planning on long term keeping trailer maybe another 3-5 years getting rid of bunkhouse and getting a RL so cost isn't justified for Rim upgrade BIG BUFORD I just called the tire store back and the USA Trail are the ones still made in the USA that's why they recommend them over the radial trail RH

    I went from ST225/75 R15 LR-D to LT 225/75 R16 LR-E two years ago. Upgraded to 16" rims. You need to make sure your trailer can handle 16" tires and wheels. I don't know of any 15" LT tires.

    I can't give you personal experience with that tire. I buy and install a lot of tires at work and bubbled a lot of trailer tires with heavy rigs.

    That said, my tire dist also said there having good luck with the Carlisle radial trail RH.
    I have a large 5er I run bridgestone r250. Love um.

    Last summer got a 20' tag toyhauler for beach, short weekends. It need tires, friend posted last week discounttiredirect on eBay was having a sale $100 off on set of tires over $400. So ordered a set of 4 Carlisle 225/75/15 trail RH, 10ply load e. $314 to my door no tax or shipping.

    Trailer I'm putting them on has a 7500 gvw so expect no issues and couldn't pass up price. I will say they seem to be improved where the tread meets the sidewall. Much stiffer than previous carlisle's I've had. Also thicker just above bead area. Time will tell.

    Ordered Friday last week at 9am, shipped with tracking # at 3pm. Tires were on door step noon today. Date codes were 51st and 52nd week of 2014.
