i have searched and searched and cant find a definite answer as to what i can put on my stock 18 inch wheels with stock suspension. i have no leveling kit.i am hoping for a 33 inch tire and if you have any suggestions as to brand of tire and even model i am all ears. i do a lot of highway driving but i am on dirt roads about twice a week and do a lot of hunting. i have had my truck for a while and its almost paid off and now its time to start modding and i know its probably backwards but i need tires now and will put a lift on in the future.

If OE height, you can put on 33's, IF you have a 4x4, and use the OE wheels.

here is a link on a different forum that I think may help

Looks like it wouldn't let me post the link.
This is off of a fitment guide on another website.

"On a stock truck without leveling kit you can run 33X12.5" tires if it is a 4WD and 31X12.5" tires if it is a 2WD, using stock wheels. "

i have 33.6x12.8x18 (325/60/18) on my stock 18" lariat wheels. sme will say its dangerous, i say i have never had a problem in the 25k miles of highway and extreme offroading i have done with them

I am wanting to put 325/60/18 Nitto terra Grapplers on my 05 4X4 King Ranch. Have you had any problems with yours?

id stick with a 12.5" wide tire or less on stock rims, you might not have problems running a wider tire on them, but at the same time do you want to spend $1200 on tire and then have problems because your wheels weren't wide enough, or they were too wide and rubbered frame,etc this is ofcourse with a leveling kit.

if your not going to level, just stick with 33's

The problem with running a tire on a wheel that is too narrow is that the center portion of the tread can wear faster than normal, similar to running too much air pressure.
