Thread: Largest tire?

  1. #1

    Default Largest tire?

    What are the largest tires I can run on a stock '94 Suburban 1500? Won't see anything other than pavement and mild dirt roads.

    Hey skiv I Just had a comment on your tire size chart. I don't think it's all that great to run an 8" rim on 35's and above. Everyone I know that did that they didn't wear evenly.

    I didn't make the list, just copied it from another site, but I can relay your concerns. Hell, my truck is still bone stock. I would like to put the 285/75R16s on it just so it has more tire, but I think it will be a while until I get any lift...if ever!

    Question- If you do this, how difficult is it to change the speedo gear to match the new size ? Just curious....
