14" to 15" tires...Any Advantages???

I have a Forest River Grey Wolf 19RR Toy Hauler.

Looking at the tires they are in need of replacing.

A few places on line sell Tires and Rims, mounted for about what the tires cost locally.

Currently I have DURO ST205/75D14 LR-C....

I want to go with a load range D as I'm close to the 1760# rating of the c tires

I can fit 15" wheels and tires and it seems there is a lot more selection for 15" radials in a D rating

Any issues with doing this?

    The load range D tires will give you a nice fuzzy but the weak point is still the axle limit. In other words going up a load range doesn't increase your CCC. So you still need to watch the weight. Unless the price between the C and D is nominal, I'd stick with the C.

    Can't answer your 15" question. Others have done it so I know you probably can, I just don't know what the caveats are.

    So I just went outside to figure out the bolt hole pattern and looked at the placard on the side of the trailer. It says this trailer is supplied with 205/75D 15 wheels and tires!!!

    What's up with this. No one swapped out the wheels and tires unless it was done at the dealer before I bought it!

    So I guess that answers my question....15" is good to go.

    Time to make a call to your dealer to find out why you didn't get the wheels & tires you were supposed to get? Or am I confused.

    Too much water under the bridge. The trailer is a 2010 and long out of warrantee. Just another thing to add to the book of why we don't trust dealers!

    THe manufacturer probably used a generic sticker.

    If I were you and were going from 14" to 15" id also switch from ST to LT.

    I thought about that, but the trailers is only 6k# and I should be good with D rated ST radials. Time will tell.

    With a trailer of that weight, the speed rating of an LT tire alone would be a huge incentive for me to go that way.
