Tire upgrade question

[Dickencider90]

I have a 2016 ram 1500 express crew cab 4wd it has the 17 inch rims on it. I would like to know whats the biggest size tire I could put on it without having to cut and I don’t wanna have any rubbing. It is stock height and already have my eyes set on KO2’s

I personally do not like how 285/70/17's handled on bends on dry pavement on my stock 17 x 7" wide stock wheels.
With 17X8" wheels they are fine.

Some don't mind the handling but it just felt squirrely if you hit a bump or the brakes when going around a bend - and they were E-load Michelin Defenders, not a low line tire by any stretch.

If you don't mind that I think some have gone as high as 305/70/17 with just a level.

Others have gone to a 75 aspect ratio vs. the 70 and those would probably be ok on a 17x7" rim.

Note, if you look on tirerack they do not rec. using a 285/70/17 on a 7" wide rim.
