Very short side walls and very high tolerance for pain, because your ride quality would be terrible. I assume this car will be strictly for show and no go...?

Tallest I've personally seen done on a first gen are 18's. Depending on how wide you go and the side wall height of the tire you choose, you may need to do some mini tubs to full tubs.

My narrow minded opinion....anything over 18's on a first gen just wouldn't look right. Just my opinion....

Team,

I think Id have to agree!

I prefer the Slammed look on just about ANY Ride... but Muscle cars!?!? OH NOOOOOOOO!!!

I think that 17's are the limit. Now 18's would look good on some 60's and 70's vehicles that were gas guzzlers.. you know.. your bigger bodied cars, but im sorry... not on a 2 door performance ride!

Now.... take into consideration all the other things that would make the car look good, like interior, paint, other resto/customizing that would REALLY set the car off and make it nice might make the difference.

But to set a 20 inch rim under a restored 68............

I had a set of 20 rear / 18 front on mine. 20" on the front would be really hard to keep any sense of sidewall. There's an article in one of the earlier Camaro Performers with pics of the combo.

From an overall performance standpoint, a good 16" or 17" works well on mine.

There was a testing on a magazine with 17" and 18".
17" was better for handling on first gen.

Ismail- Not trying to start an arguement...but where did you read that because I'm pretty sure that's not true seeing as I've ran both...?
Donnie
Also, if memory serves, the camaro performers mag with CARLC's car showed slightly better handling with the 18's than the 17's...

Its true Camaro performers did run a test in the summer of 2002 edition I believe...they felt the 17's were the all-round favorite, but the 18's looked killer though! -C.

Boy!! I can't even picture wide 20's on the back and say average width 17's on the front??????

NOw I will say that if the 20's are made 20 x 6 with 3.75 b/s they WILL fit fine like stock AND you can mount upwards to a 29 to 29.5" tall tire!!! You really should check this though b/c all our cars seem to different..

Might have to pein the front and back a schosh but this should fit.

The old 9.50-14 Firestone Town and Country Mud& Snows I had on my stock 14" x 6" with 3.75" b/s rims fit fine but I had to raise the back of my car about four inches using coil-over shocks!!!rims

My buddy Bob that I worked with on the N&S RR steel gang up in Iowa on the Red Rock Dam track moving project back in the winter of '66/'67 had a pic. took by one of the other gang members of my car with four of us standing around it from the back and you can plainly see how high she was raised up with the old M&S's on it!!

Cool

I said it!!

Just add coil-overs and raise her up until you can fit whatever tire you want like I did back when I was a kid!!

I did the 18's 20's thing, back in '99! Pretty much the same backspacing rules apply as a 17 or 18. About 5" bs on an 8, 5.5 on a 9-9.5. 245 and 275's.

They were 20"/18" x 8" with a 4.5" offset. A 5" would have been better. The tires were both 245/40's.

Everything fit fine. There were two drawbacks. First, due to the short sidewall there was very little warning before the tires broke loose in a turn. When they did break loose they broke hard and fast. Second, the short sidewall would not have worked for me on a long-term basis. On more than one occasion lately I would have wrecked the rim on a canyon road due to the thin sidewall providing less damage protection.

We could not take the 17's on the slalom course due to an incorrect section height. These tires on Kevin's Monte Carlo spanked. They are a sport truck tire so the sidewall was a bit funky, but they worked.

The biggest difference, from a performance standpoint, was the tire. At a later test I ran a different 16" tire than in the tests and managed to easily better all of the times in the magazine. The current drawback to 16" rims is that the tire sizes we can use are becoming harder to find. If I had to do it all over again I'd look real hard at 17's strictly due to tire size and performance capability.
