Thread Tools. I got some 18" rims for my car firebird like a year ago and the offset or backspacing is not right for my car. So , now that I got a little more money I am going to get some new rims. But this time I want to be sure and get some that not only look good but fit my car exactly and don't stick out any. View Public Profile. I think the offset for the stock wheels is 46mm. Just curious what wheels do you have right now?

Do you have pictures of them on your car? I am looking for a set of 18s and since I do not drive my car in the rain, I may be interested in yours, but I would have to see how far they stuck out? I am looking for something agressive, but not crazy. Later, Aaron. Find More Posts by akrott1. The stock 4th Gen wheels are 16x8, with a 55mm offset.

That produces roughly a 6. That produced roughly a 7. For a 17x9 or a 17x9. The ZR1 replica with a 56mm offset has that dimension and fits correctly. I can post pic's of them if you want. You could also go as low as a 7. That is about a 45mm offset. In the back, you can use as large as a 7. That will require some inner fender massaging though. Find More Posts by Injuneer.

Originally posted by akrott1 Do you have any recommendations for Tire Width per wheel size. For example, If I have a 17 x 9, what is the widest and narrowest tire I can put on this rim and still be ok?

I have heard of some people putting 's on a 9in. If I get 17 x 9's, or 18 x9's on all corners can I put a up front and a in the rear? Thanks, Aaron. From the Skulte website Use at your own risk.

Offset is what really plays into this. I have seen as big of 20s on these car but that is fairly uncommon. This chart may help. Originally Posted by joshb Posted from Android App. Stick with 17s imo.

Most of the high end wheels come with a decent sized lip. If you are going for a budget wheel you can always buy a vette wheel from OEWheels.

They have a lip on them. Mine have a lip too, mine are what are considered deep dish in the rear. I didn't have to alter the car at all. Since most wheels are mass produced, they have a large center bore to accommodate several different vehicles.

If this is the case, it is recommended that you use a hub ring. Hub rings are hard plastic or metal ring that fits between the wheel and the vehicle. This centers the wheel perfectly on the hub ensuring that there is no run out when the wheel is installed on to the vehicle.

Wheel offset is the distance from the mounting surface of the wheel to the true center line of the rim. This in effect brings the tire in to the fender well more. This will cause the tire to stick out away from the vehicle. This information is accurate to the best of our knowledge.

need backspacing suggestions for2nd gen Firebird

For the Second Generation Trans Ams, there were quite a few different wheel and rim combinations that you could order. I will try to cover a few of these here and give you some examples of different styles and sizes. The rims changed sizes, shapes, and colors depending on the year and what options you ordered on your car.

I will try to touch on each one of these in a little detail to show you some of the differences. The Rally and Rally II rims came across the widest band of Firebirds from all the way up to They were considered by most to be the "basic" rim used on the Firebirds and Trans Ams.

They came in varying sizes like 14x6, 14x7, 15x6 and 15x7 and most of the time had a trim ring and centercap installed. They had a "two-tone" paint scheme used and were typically painted gray, but also could be painted to match the body color of the car. The honeycomb rims made their debut in and lasted until when they were replaced by the snowflake rims. Unlike the Rally rims, the honeycombs rims really only came in two sizes and two colors. They had the 14x7 and the 15x7 honeycomb rim.

And the colors Just like the rally rims, the honeycomb rims came with trim rings and centercap. The honeycomb did also come in gold for the 50th Anniversary, but you could not get them in gold for any other Firebird or Trans Am. The snowflake rims made their debut in on the Pontiac models and continued until They were most popular on the Firebird and Trans Am, but you could also order them on other Pontiac models like the Grand Prix and Sunbird.

The snowflake rims in came in a 14x6 inch and a 15x7 inch. The 14x6 inch you could not order on the Firebird models, only the 15x7 inch size. At the start, the snowflake rims were available in different colors such as white, grey, blue, gold, and red. Now, due to the popularity of the snowflake rims and trouble in production to meet the demand, the snowflakes were canceled for the other Pontiac models.

They were canceled "due to limited supply". Also because of the limited supply, the white, red and blue colors were canceled and you could only get the grey technically called "argent" or the gold snowflake rims. See the bulletins listed below. Now, the "specialty" Firebirds like the Sky Bird, the Red Bird, and the Yellow Bird still came with the painted rims to match the body color of the car, but this was the only exception.

In and , you could also order "natural" which was a bare aluminum rim as well. There is more on the snowflake rims listed below. The 15x7 inch snowflake rims came in two different variations. Most people do not know the difference, but when you put them side by side, you can definitely see the difference. Here you can see the difference between the 15x7 inch snowflakes for left and right. You can tell from far away by the inner most circle has edges on the right and not the left.

Also, the outer most circle has openings on the left, but not on the right. Now as far as which rims were used on which cars and why they still had both styles in to is still left to be determined.

So, if you are looking to purchase a set of rims off of someone from the Internet, make sure you look closely at the photos to make sure the rims you are purchasing are all the same "style". I have seen plenty of auction on Ebay or ads for rims for sale where there is a mismatch of rims for sale. So study the photos closely and you will be able to tell if all fours trims that you are purchasing are the same.

In , Pontiac came out with the WS6 handling package which included new 15x8 inch snowflake rims. They do look similar in nature, but are definitely different sizes as you can see in the photo below. The 15x8 inch snowflakes shown on the right had a 1 inch lip surrounding the outside edge of the rim that gave it the extra 1 inch depth. Now again, just like in , these rims could only be ordered in the agrent grey or gold colors.

The gold rim was typically used on the Special Edition Trans Ams, but you could order gold 15x8 inch snowflake rims and any Trans Am from to with the WS6 handling package. In when the gold rims first came out, they were painted all gold except for the outer lip of the rims. Typically you see this style of gold rim on the Y88 Gold Special Edition rim, but this was also true for any gold rim ordered in early As you can see from the photo below, the rim on the left was the all gold rim used in early that was painted except for the outer lip, and the gold rim on the right used late through is painted gold only in the recessed areas of the rim.

Now when they made the change from the all painted gold rims to the machined edged gold rims is anyone's guess right now. My research has shown that it happened sometime in , but when and why they made the change has yet to be seen.

We do know in the all painted gold rims were gone and they were all the machined edge for the gold rims. The argent grey rims never had this type of a paint scheme or change, it was only the gold rims. There are also differences in the 15x8 inch rims as well. As you can see in the photos below, the edges are different on different rims. The 15x8 rims from early had sharp corners around the edges and the ones from late and later had more of a rounded edge.

The spokes in the middle are also different. It isn't by much, but you can definitely see a difference. Also, there is more even in the later style rims.

I have found at least 4 different variations on the 15x8 snowflake rim maybe 5. So, if you are looking to buy or replace just one or two wheels, make sure you get the right ones. Some people point out that you can also tell the difference by the location of the lug hole in relation to the valve stem. If you notice in the photos below, the rims have different locations of the lugnut holes. Some are to the right of the valve stem, and some are to the left of the valve stem.

The turbo rims were introduced first and came only on the 10th Anniversary Y89 Trans Am. The Turbo rims for and for the Turbo Trans Ams came in two sizes and also three colors. They were finished in a natural color and had a machined face with silver painted inside the fins like on 10th Anniversary Trans Ams. They also came in gold for the Special Edition Turbo Trans Am in and which could also be ordered for a non-Special Edition as well.

And lastly they came in white for the and Y85 Turbo Pace Cars. It is hardly noticeable but when you line the two up together, you can definitely see the difference. From the top looking down at the Turbo rims, it is hard to tell.

In the photo below you can't even really see a difference can you? Ok, besides one is real shinny and the other one is real dull. The difference between the rims really comes in the depth of the front dish. The rims are real close in height. The difference come in the front dish depth of the rim.

It is really noticeable when you look closely at them. So, if some one is selling you a set of Turbo rims and you need the 15x8 inch ones for 10th Anniversary cars, then ask them the EXACT measurements on the height of the rim. Well, they aren't. Don't take round numbers like "Well, its about 9 inches The last thing to take a look at is the measurements for the rims.

I get alot of questions on people who want to change rims and ask what other type of rim will fit. So what I will cover is how to measure the rims to know if the rim will even fit the car.

The first thing to take a look at is the lug pattern. What does this mean? So looking at the rim, you can easily tell if it has 5 lugs or not. But the correct spacing for measuring the lug pattern is done by measuring from the back on one hole to the center of the hole diagonal to it shown below.

The next thing to take a look at is the offset and backspacing for the rims. The backspacing is easy to measure. Place one of your rims up on its edge and take a measuring tape and place the end of it flush to the back inside of the rim where the lug nuts would attach where it would sit flush against the hub or drum of the car. Then take a look straight down the edge of the rim and see where the edge of the rims line up and take your measurement shown below.

The last item to take a look at when thinking about changing rims on your car is the offset of the rim. The off set whether it be positive or negative does make a difference on how the car handles. To determine the offset of the rims, you first need to measure the width of the rim from edge to edge.

Divide that in half to get the centerline of the rim. Now take your backspacing and subtract the measurement of the centerline of the rim from it to get your offset. So, once you know the lug pattern, the backspacing, and the offset of the rims, then you can determine what rim you would be able to fit on your car.

The measurements of the stock rims on the Firebirds and Trans Ams are as follows:. Hitman's Pontiac Trans Am Site. Toggle navigation Main Menu. Call us: It's all here. Overview For the Second Generation Trans Ams, there were quite a few different wheel and rim combinations that you could order.
