1978 Scottsdale K20 - tire size stock suspension

[BenningJ]

I have checked every thread in the 'tires/wheels' section and haven't been able to find the answer I was looking for.  So here is my question:  Will 265/70R17 tires fit?

Information:
Stock suspension (will add a 2" lift next summer)
17x8" 4.5bs rims (8lug)

My main goal right now is to get the truck running and have some decent tires on it.  I live in the north so I am wanting to buy some A/Ts; either BF Goodrich or General.  (I have good experiences with both companies)

Thanks for your help.

I think I have 265/70R17s on my '77 K20.  They fit fine with the stock suspension.  I had some rubbing issues on the front tires when backing-up and hard turn, but I went back to Les Schwab and complained that they gave me rims with too much back-spacing and they gave me the next one down and it completely solved the issue.  I drive this mildly off-road during hunting season, take it in the snow and haul at full capacity from time to time.

I'll double check when I get home the tire size.  I think your tire size should work!  Those 265/75R17s are about 1" larger in diameter and only 1/2" larger in radius than what I am running.  You might rub a little from time to time before you get the 2" lift in; depending on how you use it.

Thanks, for your reply.  It is what I was looking for.  I figured a 265/70R17 would fit. 

I changed my original post to the correct tire size: 265/70R17.  Would you be able to check your backspacing for me?  I expect to be doing quite a bit of offroading and hitting some mud roads as well so I wanted to be sure.

Thanks again.

Here is my '77 K20 with stock suspension and 265/70R17 Toyo M/Ts!  She's a little dirty right now, but hey...it's a truck!! 



The wheels I believe are an older version of the Ultra Wheels 'Crusher'.  They are a chromed aluminum.

Also...The backspacing works without the fender extenders.  I have some stock wheel-well trim that I want to put back on there and get rid of the fender extensions, but I have a little bit of body work to do before I pull off the extensions.  Like I said before...Les Schwab's first try on the wheels had too much backspacing.  They rubbed pretty good at full lock, so I took them back and we went with slightly less backspacing and it hasn't been an issue since!
