Question about new Rims

[ma-skis.com]

I'm buying new (used if they come up) rims for my car, I'd like to use the stock rims for some new winter tires (which i will also need) and put my current all seasons onto the new rims.

Concerning size, how do I ensure when I buy a set of rims I'll know they will fit short of putting them on the actual car. Am I just looking for a 16" rim with a 5 bolt pattern? I feel like I am missing something from the equation.

I'm not buying spinners or something, just thought i'd get something that looked a little nicer than steel tires and a cover plate.

You need your bolt pattern. 5x115 or what not. Not all 5 lug rims have the same bolt pattern.

If you're looking for a winter wheel just get a steel wheel with snow tires on it and call it a day.

It is also important to know your offset, so the wheels won't rub against the car or suspension. What kind of car?

2x Not all rims have the same offset, notice the tires that sick out but arn't really that wide.

Seems chevy trucks are the most common like that, must just F'up the wheel bearings and ball joints.

2010 matrix, I'm assuming the bolt pattern number can be found in the manual,
I'll check there next, if i was buying a used set of rims would that information be found on the rim itself?

You need offset and rim width. You should be able to find these on the back or the inner rim wall on your current set.
Easiest thing to do is just buy new rims of the same width and offset, however if you're going for nicer rims you might not want to.

Changing up the offsets and widths can give you a more aggressive setup which is what a lot of people upgrading their rims like to go for. You can even go for a staggered set up where the back rims and front rims (and tires) are different sizes.

I just got new wheels for my car, so did all sorts of research on this stuff. Ask away if you're got more questions. I'd try to find online message boards for your car and see what others have done and the measurements they went with.

This just has the 14" rims, I know the Matrix came with 17" but the bolt pattern will be the same. If the rim width doesn't change neither will the offset.

Not true

Well I haven't researched it but I know your going to F'up your wheel bearings and I suspect the spindles, ball joints etc.

It's common sense, changing the off set will move the load away from the center of the bearings. as long as the offset is the same you can put wider rims on until they rub.

Base Matrix or XR? Base matrix has 4/100 bolt pattern while XR has 4/114.3.

Wrong. Toyota used 2 different bolt patterns for the base model vs. XR/XRS Matrix.

a lot of info on the web about bolt patttern, offset and how much oversize you can put on your car without harming it. My stock tires were 195/60/16's and I run 215/55/16's in the summer now.

Perhaps you should research it instead of giving false information here. This is completely incorrect.
Changing to wider rims without changing offsets is where you will have issues, or changing offsets and pushing small wheels too far out (like the Chevy's you mentioned).
They need to be adjusted together to compensate for any changes and maintain safety, handling, fit and not damage the car.

Here's a good calculator to figure out new offsets needed to match a change in rim size.

Look smart mouth, I said I didn't research it, but it was very easy to understand my post, my statement that the bearings would be overloaded if the wrong offset was used was very easy to understand and sound advice.

My thinking is, the offset must be maintained regardless of rim width, and you think I'm wrong because the offset number changes...

Changing the offset number is not the same as changing the offset, in fact changing the width of a rim would require the same offset.

To maintain the same offset (like I recomended) you need a different offset number.

Frick I hope I'm right on this, LoL

You also need to make sure the wheels have the correct hub diameter. Too small and they won't fit, too large and you will need to buy some hubcentric rings to avoid shaking.

Sorry, wrong again.

I'm not trying to be a smart mouth, but you quoting me and saying "you know I'm going to F up stuff" based on my correct advice made you look like a smart mouth who hadn't done the research to back it up.

And the offset and offset number are the same thing.
It's not offset # + wheel width = offset, as you're saying.
Offset is the distance from the hub mounting point to the center of the wheel.

I understand where you're coming from in terms of keeping things in line with the wheel setup, but you're advice and explanations are off.

OK, I agree with this, and your saying this offset must be changed for wider rims, and I'm saying it will overload the bearings.

That is where your logic lost me and why you keep saying I'm wrong.

I didn't say that.
