D or E Rated Tires?

[Road Geezer]

I'm not sure what the manager was afraid of. I think she had never done a trailer before and was afraid of screwing something up. Might also just have been an off day. She wasn't the manager I had spoken with when I ordered the tires.

Ah, so that is most likely why the manager didn't want to do it.

Before I switched to 16" wheels, I went to E rated tires on my 15" wheels on our Classic 30. They were Alcoa alum. wheels, and as I recall, they were stamped with a max. pressure of 95psi.

Why not just go with 15" LT's rated at D; it's still much better than any ST's.

Finding a 15" LT tire from a major brand will be the challenge.

That is why many of us went with the Michelin LTX (P) 235/75R15 XL tires on the factory 15" wheels. There is still adequate safety margin on the 27/28 models with 7,600 pound GVW even with the derating to 1,985 pounds per tire. The trailer axle will sit about 0.30" higher.

Click on images below my handle to see an image of the standard OEM tire beside both a 15": Michelin and later a 16" Michelin. The 16" tire only raises the axle 0.45" over the OEM GoodYear ST tires.

There's a Goodyear LT cargo tire load rating D that I almost bought but the size brings them down about 1.5" from current height and I didn't want to readjust the hitch. Maybe next time.

Edit: I think it's a 220/70/R15 compared to the 225/75/R15s from Michelin. But it's a fully D rated LT tire made in France. Standard in many sprinter vans.

The size is 225/70R15, and it will lower the trailer 1/2"

2 other alternatives is the Pirelli Scorpion ATR LT235/75R15 load range D and the Nokian Rotiiva AT LT235/75R15 load range E
