now, I know I should use a 205 55 r 16
but I've got an extra set of Ronal R28s from my VW and I just picked up a mint set of 225 55 r16 tires for free
is it worth mounting them?
they are about 3.38% larger in diameter, I don't think it will rub the fenders
has anyone done this?
and disadvantages other than maybe looking a bit goofy, slighty worse mpg, and a speedo thats off by 4 mph?
from what i understand is its going to rub try to sell them and get 225/50/16?

sorry, I mistyped, they are actualy 225 50 r16s
I'm pretty sure they won't rub seeing as she is at stock height, and if they do I own the profesional fender roller, but my concern is more the fact that I have just about twice the hp that the car (the 96 2.2 auto in question) in my VW and I have a smaller contact patch (maybe I'm just jelous cause I wouldn't be able to clear a 225 on my car)
think this car will be able to move outa its own way with more weight/ friction from the larger contact patch?
225's will be fine. I don't think the contact patch will have sufficiently increased to the point where it slows the car down enough to be noticeable.

I have 225'/50R16's on my 97, works fine at both stock height and lowered.

good to know, is that pic in your sig thge car with the 225 50 r16s on it?
it looks nice!
okay, so if they will work out pretty decent, I've got another question:
are stock chevy lugbolts conical, or taper seats?
I took a quick peak at the lug nuts she has on her stock steelies yesterday and they looked a bit big to fit in the lug locations of thre ronals
is there any good place to get a set lugnuts cheaply for these cars with a taper seat surface online?
and which size do I need
J-body wheel lugs are M12x1.5. you should probably look at somewhere like Jegs or Summit. they should have them.
you might even find a set on eBay cheap too.

it shouldnt rub at all, but check to make sure that your bolt pattern is the same.

quick tire lesson for you. the first number 225 is the mm is the side to side width, the 50 is the mm from the lip to the top of the tread and the final number is the diameter of the wheel. at certain points going wider will mean that you need to go thinner. till you reach the ultimate space there to wide will rud on the suspension.

Care to elaborate?
Best I could get is that "by going wider will mean that you need to go thinner" would entail that by going with a wider than stock tire, the sidewall height goes down?
Going from 205/55r16 to 225/50r16, the sidewall maintains virtually the same height -- 4.4"

Wrong. 50 is the aspect ratio, or % of the tread patch. Using what you said, the 205/55r16 would have just over 2 inches of sidewall, when in fact it is 4.4"
Using this site:
http://www.miata.net/garage/tirecalc.html and the largest tire, smallest aspect ratio the calc can do -- 335/25r23, it shows the sidewall to be 3.3", not the 1" that your explanation provides.
The sidewall height will
always be a percentage of the treadpatch (where 205 = treadpatch in mm, 55 = sidewall height as a % of treadpatch, 16=rim diameter.
I have Yokohama Es 100 ...225 50 r16 on my stock 99 z wheels, and they fit fine. I'm also lowered on eibach pro kit springs. You'll be fine.

actually the 225 is the overall diamiter of the tire itself the 50 is sidewall hight and obviously 16 is the rim size

I'll give you one and a half out of 3.
225 is the width of the tire, in millimeters, not overall diameter. Half a point for the sidewall height, and 1 point for rim size.
Here, I even sourced where I got the info originally:
http://www.1010tires.com/tech.asp?type=tires

The "215" is the width of a tire, also known as the "section width". This is the width of the tire in millimeters at its widest point from sidewall to sidewall when mounted on the recommended rim width. The actual tire width can vary depending on the rim width it is mounted on.
The "65"is known as the Aspect Ratio. It is calculated by dividing the section height by the section width and multiplying by 100. (In this example, the sidewall will be 65% of 215)
The "R" stands for Radial, meaning it has a radial construction. Radial tires have ply cords that extend to the beads and are laid at 90 degrees to the centerline of the tread, the carcass being stabilized by a circumferential belt. Other possibilities include "B" for belted construction and "D" for diagonal construction. This means the ply cords extend to the beads and are laid at alternate angles less than 90 degrees to the centerline of the tread.
The "15" stands for the diameter of the wheel in inches. This is the exact size that this tire will fit. There are some older rims called "TRX" which are metric measurements like 390. You CAN NOT mix TRX rims with regular tires or vise-versa.
