First off, why in the world are you putting non-standard sized rims on your camaro? If you actually wanted to have a cool ride, you should have done some studing on the dynamics of tire size. Larger tires/rimms, means more work on the braking system. Youor standard size was either a 14" or 15" rim and with a set of "70 series" tires on your ride, you could as much as a 265 high speed multi rated radial for your car. But now you want to put on some ******** DONK rims for something that is not designed for this application.
First, you should have measured the actual tire height of your standard application. Next you will need to subtract the actual size of the rim you are changing out to. Then you have the height of the tire size you need to keep the same height of the standard size.

Your suspension was not designed to run 17" rims on the camaro. You will need to make the neccessary brake changes for the larger rims. Plus your turning radius is now 4" less from corner to corner due to this change.

Good luck.

It's called Hotrodding...................


Even though, I am not a fan of these larger rims, I cant see how they would affect anything. These 17 in rims usually use a lower profile tire which will make the outside diameter of the tire the same as a 14 or 15 in tire/wheel combo.

Maybe I am wrong about all this....enlighten me.

I think he is asking what width will fit under there. I know a quite wide tire will fit under these cars. My concern with all this would be.............496 Big Block, stock rearend plus wide tires..........equals.......breakage

Lord Maximo, nice words of encouragement. With some research, you would find tires that are the same overall size, just have larger rim sizes. Sometimes you need bigger rims to fit bigger brakes. That is why we are putting 18" wheels on our 68 Chrysler Imperial project. With 29" tall tires. SAME overall diameter as stock. What does the car care what the rim size is? The od of the tire is what matters.

You are right poncho

Here is a link to a spiffy chart that helped me understand the bigger sizes. http://victorylibrary.com/mopar/car-tire.htm

I doubt is some of the tires on that chart actually exist, so you need to go find a tire company you like and.......

Go to that tire companies website and get to the pages that have actual tire sizes in section width and overall diameter and suggested rim width, it makes selecting a tire easier.

Here is a sample page from toyo tires, of the sizes available for only ONE of their tread patterns.
http://www.toyo.com/docs/tires/produ...category=sport

not my favorite company, but indicititive of the resources that are available by looking on line. I just went to the website, picked a tread that looked cool , selected "sizes and specs" .


Most of the manufacturers have pages similar to that one.

Get your pencil and paper ready, especially if you want to find bigs and littles in matching treads.



Have fun,
Mikey

Here is one more thing to consider when choosing to go with the larger rims, , a larger rim may keep you legal when you start modifying your suspension to make your car lower as the increased rim diameter will raise the scrub line.

Another handy site I found a link to is this dynamic version. Plug in the info and get a view of what the tire would basically look like on different rims. Along with this and a coupe pieces of cardboard I've measured enough to get a good idea of what I can run. Helps to figure out those milimeter wheel offsets as well.

I put 24 inch rims on all types of cars everyday and with some work you can make anything work.A 17 inch alum, rim is not going to change a hole lot so u do some studying there vette rims i dont want mine to be like everyone else's with drag lite or centerline rims and it will look alot better,and i have seen vettes run low 9s with the same type rims with drag radials.turning radius is not going to be cut 4 inches either
