i find a lot of information on putting bigger tires, but how about smaller? i do very little, if any, off road, and would like better fuel mileage. also i am looking for a deal, and if i know what range would work i could take the best deal i can find. thanks!
ps would 215 65 R16 work?

If you have 16" wheels, the smallest you can *safely* go with the weight of these trucks is nothing below what it came with from factory. If it has 16" wheels, you can't go smaller then 225/75 R16

Same thing if you have 15" wheels, only it would be 235/75 R15

If you put anything skinnier, i.e. 215 versus 225's, it would probably be more prone to get out of control quicker....215's IMHO are for a lower ground clearance vehicle that doesn't have the notion to be top heavy.

These trucks are built like a moving box, you're only going to get so good of gas mileage. My rodeo came with 225/75 R16's from the factory, it gets the same gas mileage now with 265/75 16's, which are taller and wider.

So you just never know for sure if it's really going to improve or not. Stay with a *highway tread* type tire, you'll get the most mpg out of those tires

How would smaller tires give you better mileage? Are you referring to rolling resistance? If so it might be worth looking at a narrower tire, but I wouldn't get a smaller diameter tire, that would just increase engine rpm and likely lower mpg.

Something like a 205/85-16 is about the same diameter as stock, but is an inch and a half narrow. No idea if that size is readily available or not.

thanks for the replies. i guess i'll just stick with the stock size, or slightly larger, given the notorious top heaviness ;-)
