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

[Rbertalotto]

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?

Out with the old...In with the new!

Ordered my 5 new tires on Wednesday and they were here in Massachusetts at 2pm on Friday. Amazing!

The old 14" wheels and tires:



And the new 15" wheels and tires:


The old tires still have lots of tread left so I threw them on Craigslist for $250. The spare is brand new and never used.

I think it looks rather "smashing!"

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.

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

Ordered 5 wheels and tires from trailertiresandwheels.com. KENDA Karrier ST205/75R15 load Range D ....$605 including two day shipping. Can't beat that with a stick!

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!

THe manufacturer probably used a generic sticker.

No issues. Just do it. 🙂

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!

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.

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

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.
