HI have a 91 5 lug truck and want to put 16" wheels on it. Craigslist is the easiest place to get nice used wheels, but which ones fit, both lug pattern and offset? Also, which size 16" tires will be the same outside diameter as my stockers? And finally, what width will fit without rubbing? I think I want 205s, but 215s might be nice too.

Thank you truck gurus!

 

I cannot help with the wheels, however if you search (google) for a tire size calculator you can find out tire sizes. There is one with a comparison tab where you can input numbers until you get what your looking for.

2wd?
16s from a 90s truck, taco, 4runner, t100 should fit.
my 4wd truck had 265, 75 16s when i bought it. Mickey thompson 16 x IDK what. I can look if you want

 

Here's a great guide for tires: https://www.tacomaworld.com/tirecalc...0r14-205-50r16
Still wondering which wheels fit... I've seen guys put Crown Vic and Mustang wheels on, they seem to swap right over. I saw some great RX7 wheels on Craigslist. Anyone know if they'll fit? I see some RX7 wheels swapped to a Mustang, but not perfect...

 

Wheel geometry is an interesting subject.

Let's start with some basic terms.

A a rim holds a tire.
A tire and a rim make up a wheel assembly.

Ok so there is what's known as "king pin" angle, this is a hold over from well tractor and cart King pins.. This is the center of the actuator that makes up the steering. (Sorry I'm not drawing pictures for this, Google!)

Ok so on your modern, not really very modern, double wishbone suspension made up of upper and lower control arms. There are two ball joints these make up the "king pin angle". So draw a line from the center of A through the center of B to the ground. This line should intercept the center of the contact patch of the tire when the vehicle is neutrally bouyent..

Right so you're with me? The rim offset and the tire height will shift this contact patch inwards and outwards, both will cause increased tire scrub (reduced tread life!) When the chassis raises and lowers. They also effect the effort to turn as well as the self centering rate (the primary purpose of this kingpin angle is to return the wheels to straight which keeps you going in a straight line with not a lot of effort)..

A side effect of this is the Ackerman compensation, this is the center of the kingpin aligning with the center of the rear tires at the ground, again this effects the rear scrubbing and steering weight..


In short what fits? Anything with the same bolt pattern.
What is a good fit? (You didn't ask this but should have!) You need to match first off the engineering design (hub-centric, which bears weight and centers on the hub OR lug centric which bears the weight on and is centered the studs and specific lugnuts)..

So you whip out your caliper or tape measure and compare your factory hub and the rims hub opening. If these are very very close, IE touching, you have hub centric rims.

Next you look at the offset. These are cast into the Toyota rims and easy enough to find with Google.

There isn't anything you can do about the lug pattern with out an adapter which changes your offset required..


...
This is why the engineering guys get big bucks..

Anything that fits the lug pattern works but not as designed.
