What tires should I get?
I was towing my TT today in the rain and a few times my rear end spun out trying to gain traction from an uphill red light. I have my OEM tires inflated to their max PSI which likely doesn’t help but otherwise the ride isn’t as good.
I made sure my WDH was dialed in correctly via CAT scales and haven’t had issues on dry pavement. My current tires have about 40% tread left.
Would upgrading my tires to LT / E rated KOAs help this any? Are there any other suggestions and what load range I should be getting? Trailer is 33’ / 7,600 GTW

OK, so softer tires make the ride "not as good" ... ok, I trust you, but am surprised. I would like to know what "their max PSI" means. Tire make/model/size and what PSI you are using would help us analyze your situation.
The WDH reduces the load on the truck rear axle and increases it on the trailer axles and front axle. My OPINION is that trying less rear tire pressure and/or less spring bar contribution would help.

The tire says on the sidewall 50psi so I inflated the rears to 50 psi cold and the fronts to 45 psi cold. I got a better tow ride out of doing that. The stock tires are 275/65/18 Good Year wrangler Fortitude HT.

I tried lowering the PSI some and although it was better with traction, the ride wasn't as nice.

E load range tires in the same tire compound (may not be even in the same.brand / line) might be better if you lowered pressure to 40 PSI and still control the bounce (I'm assuming that's the reason you raised pressure).

Most OEM spec a minimum tire to meet the rating in CWL (Constant Working Load). For a 2250 (9.75) or 2400 lb (9.75HD) CWL would require a Sidewall Rating of 3094 or 3300 lb for a Pmetric.

Some people don't like the extra bounce and deflectuon you get with P Tires. Some people also need the extra sidewall thickness if they deal with shale and flint a lot.

i put e rated nittos on my 15, made no difference in towing the rv. Had the same tire on my 07. Rode like crap, and not needed. My 18 has d rated, when towing i max the psi. Does the same job and maintains a nice ride while not towing. If one doesn’t overload the 1/2 ton, e rated is a waste
The LT245/70R17 E Goodyears on a 2016 F150 Scab 4x4 rode just fine with 40 psi. It certainly wasn't a night and day difference between them and my 2015 Scab 4x4 with P265/70R17.
