Ok so I have been searching the forum for a couple days trying to find information on how big of tires will fit on a 1st gen truck, but I have found nothing besides the the Ifs thread.

Is there a thread for SA tire fitments? Because I couldn't find it at all.

Now to my question. How large of tires can I fit on my 1981 Toyota long box 4x4? It's a project truck and for now it will be a solely trail truck and I was just wondering what is the biggest size with no lift? And what is the best size based on experience? Any help is appreciated.

 

If your spring s are in good shape 33's but they will rub periodically.
32's more realistically

 

A friend of mine had 32x11.50s on his stock '81 with only a little rub at full flex. I wouldn't go bigger than 31x10.50 myself though.

 

good spring rate? 33x10.50s.

 

Here's my 89 with stock suspension and 31 10 50 15s, the tires are garbage but they came with it, Im looking at Firestone destination a/ts

Might have to go to my album since the app said I already uploaded them? Lol

 

33 12.50

 

Thanks for all the feed back!

 

my friend runs 38 12.50 tsl on factory lift he just tubbed out the fenders

 

35x12.50s stock 4runner besides airbags in rear , very minor trimming i just did this today and took it wheeling worked great
