Oh no...not more tire/wheel ?'s

265'x16 won't support your rear weight ? I thought you looked into that when you bought this new camper . Those OEM GM wheels have a 3500/3700 rating. tires = 6830.

You might need a spare tire too, check into that. If you do, where will you carry it ? Under the truck in the OEM carrier ? Maybe , maybe not depending on the size.
You have limited slips in your 4x4 , so be careful with tire size on the same axle.
Look into swapping one of the fronts to the rear and maybe you could get away with running 2 diff diameters on the front for a short ride if you had to.
As I have found out , a lot of places are closed on Sundays , so finding a new tire to match a 19.5 might take a few days .


The new tires will raise the height of the whole package, you might feel that in crosswinds. I know it's only an inch but it's a 16 ft long inch on a SB truck.

I assume your warranty is expired . GM might not like the idea of a tire swap.

There are a lot of extra expenses that tag along with the 19.5's (mount and bal., off set )
Look at it on the Rickson Wheel website.

The trade value of your truck plus the money $4-5k spent on upgrading it to fit the new camper might be a down pay on a new or different (new to you) truck heavy enough to do what you need w/o mods.

Hi bob, yeah not ready for new truck...love our 06 Duramax.
The 265's have been great...but starting to show wear at over 30k miles...so starting to think about what is next and why not go to more capacity?
Already swapped out the spare for a 5th 265 (which does fit underneath).
