TowRig.com - Diesel Discussion and Tow Tech

I'm still getting used to my first new used truck. Lots of newbie questions yet. :confused:

I bought it in Minneapolis from a dealer who couldn't/wouldn't tell me much about how it had been used, but I knew going in, from the independent inspection I paid a diesel specialist to do that, that it had been used off-road a good bit. Nothing wrong with that; just something I observed in deciding to buy it.

It has Goodrich All Terrain LT265/75R16 tires.

I used to remember how to read that lingo, but I'm not sure any longer.

What I'm really about to ask is this:

Can I use 16" tires that are narrower than the 265, still fit on my 16" wheels, and have a lower overall diameter, so the entire truck sits an inch or so closer to the ground?

Or would I have to buy four new wheels, as well as new, narrower tires to fit on them?

Finally, since I use an equalizer hitch, which is set for a particular set of dimensions and angles between truck and trailer now, if I do lower the truck, would I have adjust the hitch also?

Factory size is 245/75-16. Technically, that is the largest size (per tire manufactures) that will fit the factory rims, which sounds like what your looking for.
I don't think you'd have to adjust the hitch for that minimal of a change.
