posted this in the exterior section, but with no results, so will post it here. have an 84 camaro that i took back from my son. well, he hit a curb and blowed two tires and ruined two wheels. car has the 5 spoke camaro wheels on it. had to drive 100 miles to get car, so called several dealers and tire centers to find out about bolt pattern. was told 5 on 4 3/4. took two wheels that were 5 on 4 3/4, and they didnt fit. measured mine and they are 5 on 4 1/2. thought i was crazy, so had my buddy the mechanic and tire dealer measure them, and they are 5 on 4 1/2. no one even shows these wheels to exist, but they are camaro wheels. trouble is, i cant find any more to match! what is the story with this, and am i just seeing things? will post pics soon as i learn how, so everyone can see i am not crazy! any ideas?

 

The Camaro is a 5 on 4 3/4" pattern. Are you sure you're measuring correctly? You DON'T measure center to center on the studs, and that's whatI'm guessing you're doing. Put the ruler on the center of the first stud, skip across the second one, and measure to the OUTSIDE edge of the third stud. I think you'll find that dimension to be 4 3/4"

EDIT: be sure to go back to your mechanic friend, and tire dealer to show them how to measure wheel patterns the correct way! [&:]

 

Could use pics, but yes all camaros are 4 3/4.

 

I agree 3rd gen wheel bolt pattern is 5- 4.750 BC

 

Thanks for setting me straight on this procedure. i always measured my wheels differently, and if they measure the same, they fit. just goes to show you no one is ever to old to learn something new, and i am willing to admit that i was wrong. with all this said, what year wheels will fit on my car? am looking at some from a 92 model, but they are 16" wheels. would rather stay with 15" so my speedo wont be off to far, but these are nice wheels, and also have heard that they are marked front and rear use. what is the difference? thanks again everyone for their input, and sorry if i sounded like a dummy!!!

 

16x8 wheels used with 245/50/16 will not affect your speedometer, The (front) & (rear) markings mean they are specific to that axle and can not be rotated. The front and rear wheell offsets are different and the reason GM did is beyond me..

 

Did they change the pattern at all in 4th gen? Ive seen some people with 4th gen wheels on their third gen. But idk if they had adapters or what not.

 

nvm, i finally found what i was lookin for. Artical said that all of the camaros/ firebirds had the same pattern, but different spaceing. So why do they have adapters to go from 4th gen to a third gen setup? is it just for the spaceing i guess?

 

4th gen wheels have more back spacing than third gen (7" vs. about 5.5"), and you would need at least a 1" spacer adapter to make it work. I already tried to put my '97 style wheels on my '91.

 

You would think a tire dealer, especialy if they sold wheels also, would either know how to measure a bolt patern or even have the tool for doing it. http://store.summitracing.com/egnsea...=KeywordSearch
Tell your guys that on 4,6 and 8 lug wheels you measure center to center straight across and on five lug the way mention above.

You can use this tire size calculator if you get a different diameter wheel to see what tire size you can use to keep the same ratio
