smaleest 18inch tire

whatup guys, currently im running 17inch wheels with a 40 series tire, i am considering going to an 18 and need to find out if there is a small enough 18inch tire to fit under my truck.

smallest tire to my knoledge is 215.35.18 most tire websites have the overall diameter of the size tire in the specs section.

215/35/18 last I knew.

Theres a 205/35 out there. I forget who makes it, saw it on eBay once looking for my 205.40s.

Ebay is full of garbadge....online yard sale

is 205 to narrow for a 7inch wheel?

I'm running a 205 on a 7" wide wheel, its a little wider than the wheel.
