Possible to convert 17.5 over to 22.5

Why do you want to convert if i may ask?

 

Lots of trailers that came with 17.5 from the factory don’t have enough clearance for a taller tire. Is this a drop deck? If so, I’m pretty sure you’ll have to raise your ride height for clearance.

At the minimum, you’ll have to change hubs. It’s not like switching from 22.5 to 24.5, the 17.5 has a smaller pattern.

 

In my experience, they tend to pop on hot summer days if you go above 65mph. It does seem like the newer tires hold up better, but you'll still have more blowouts, tire wear, and brake wear than you would with 22.5. They are just so small, turn so fast and the brakes are smaller.

We run some 17.5 on drop decks because we need the lower deck height, but I see no advantage with running 17.5 on a RGN. You can find a market full of 22.5 equipped RGNs that will be every bit as low as the Talbert you are looking at.

I would imagine the reason you are interested is that it's at a low price, the 17.5 rubber is why the price is low.

 

Question if you have drum brakes you would have to change drums along with hub and wheels?
Would the bigger brake shoes that fit a 22.5 drum, work with the pins for the smaller shoe.

Would it be best just to by complete new axle assembly?
I think that would be the better option and buy with disc brakes.
Good luck

 

I run a drop frame van with 17.5 tires. I don't have an issue wi tires blowing or brakes wearing faster. I also run 18 ply tires.

 

I'm curious what the deck height is with the 17.5's
