So I’ve got a 2013 F250 lariat 6.7. I don’t have a level or anything. Stock suspension. The truck has stock wheels that are 18x8. I’d like to know what the biggest tires that I can put under it without getting a level. Thinking about getting new 18x9 aftermarket wheels.
Thanks!

‘Biggest’ as in widest? Tallest? Heaviest? Most side wall? It would be helpful to have more info about what you are looking to accomplish.

I guess tallest. I like sidewall. And I do some hauling but nothing too extreme. I don’t need a wise tire but want a nice stance. Sorry for not having enough info.
I heard 33s work. And some 35s work

With 20” wheels, many guys have the 295/65/20, which is a 35” tire.

Does that change with the fact that I have 18” wheels? Or does that size stay primarily the same?

As noted above, 295/65/20s are a great height and width for a stock or leveled Super Duty. They are also rated for the OEM wheel width, whereas most 35x-12.50x20s are not. They also have a higher load capacity than almost all of the similar sized flotation tires.

There is a similar size in the 18” rim variety. It is a 295/70/18.

Those definitely do look better and fill up the space without sticking out! Thanks. Getting money together to delete my truck first. But then I’ll probably look towards that same route!

I’m about to put the 295/70/18 on my 2011, except I just did a 2.5 level kit and 5” rear blocks on it. Thinking they’ll be a perfect fit.

I have 35x12.5x18’s on my 2015 F350
