Default Dually Tires

I have looked and am unable to find any information and I guess I am taking the short cut by just posting my question, but maybe one of you guys can help. I was wondering what is the largest tire I can run on my truck and still have it usable. I do not mind the idea of spacers or anything like that, but I do pull, but I also go way down the beach and would like a better tire with higher flotation. Thank you very much for your help.

I was going to do 34 by 10.5 interco on the back and run 315 70 17 in the front on reg rims(removing the dually spacers on the front). But that would cause you to need 2 spares. Or wife on stand by with a jack and a tire. I have not done it yet because i have not yet robbed the bank.

Hi,
I have just changed my tyres for narrower ones (standard dually size) because when I fitted my truck camper the bulge at bottom rubbed. even with max pressure.
So be aware that if you carry heavy loads, that you must be able to use HIGH pressures, and watch that tyres do not touch.

I have ran both 265/70R17 and 285/70R17 on my 06 dually and my recommendations are as follows:

With 265's put them on and run it, no clearance issues at all.

If you want the 285's you will have to run a spacer between the rears or they will touch. I run mine at 80psi all of the time and they do touch lightly- especially when loaded, something the DOT does not like to see.

That sounds good, where would I get and what size spacers would be best.

If you deal with a decent tire dealer they should have a line on spacers. I don't have any yet but will be soon.

Been quoted anywhere from $80 each to $400 each. Whatever the price make sure and get good quality ones, I have heard that the cheaper (cheaper aluminum ones) ones will fail (crack) under load.

Sounds good, I have also been looking at maybe converting to a srw with a set of 37x13.5 toyo's on weld wheels from Kore performance. I do not pull a lot with the truck anymore, kind of turned into my play toy. I think that setup maybe a little better in the loose sand down the beach. Any thoughts or suggestions? Thank you very much.
