I am restoring my 69Z and I was considering installing the correct tire for that year which is an aftermarket Firestone/Goodyear e/70-15. My question is what are the pros and cons of the old tires? Are they strictly for show or are they acceptable for easy cruising and such.Thanks

Bias ply tires tend to "pull" a little due to road irregularities. Radials give a better ride and all around handling. You might get lucky and find a set of original "look-a-likes" but are radials. I would only do the radials if not a stock show car.

Does anybody know where to purchase a radial tire that looks like the original stock bias ply tire?

I found this on Yenko.net It looks like interesting reading for 69 Camaro owners.

Some folks, like Charley, know this but (judging by the great number of 69 Camaros and Chevelles with Polyglas), many don't.

Fiberglass belted WHITE LETTERED tires were not an option for Camaros or Chevelles in 1969. There is only one tire currently reproduced that is correct for these 69s in RWL and that is the Goodyear Wide Tread. The Firestone Wide O Oval being reproduced is the 1970 fiberglass belted version and is incorrect on 69 Camaros and Chevelles. The 1969 smaller lettered Firestone is not FG belted.

Belted vs. non-belted was confusing even in 1969 as the Goodyear Polyglass Custom Wide Tread IS technically a wide tread, but the correct tire is white lettered "Wide Tread" only (no "Polyglas" in white letters). I have numerous contemporary 69 road tests that clearly show a Camaro or Chevelle with non-belted Wide Treads and the caption or text refers to them as Polyglas - an obvious error.

Note that fiberglass belted tires WERE available in 69 for the Camaros and Chevelles in red or white stripe (unbelted too).

So many nice, otherwise correct cars have the wrong tires on them. A case, I believe, of relying on other restored cars as a model and not doing the research. It has snowballed..............

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

Take a look in Street Rodder or any of the magazines out there for the "older" cars... seen ad's but can't recall company name.

There are actually two types of 'bias' tire constructions. Bias/ply that was used from the 60's and earlier and bias/belted that was used from the 60's until radials (that are always belted) took over.

Hi, I purchased a set of CORRECT Bias Ply Repo Goodyear Speedway E-70-15 Wide Treads from Kelsey Tire. I personally would not drive on them, they are kinda scary the way they wander at slow speed.
I mounted them on my original YH wheels, and only use them for display purposes. I drove the car home from the shop and that was enough to convince me that newer tire technology was the way to go!
I Have another set of driver tires ( Goodyear Eagle GT ) on another set of YH wheels for cruising. Hope This Helps.

You mean ta say you drive at low speed????

Just kick it up a notch AND I bet that wandering will just feel right a home since that was the way our cars were way back then!!

PS., there was an old steel decked bridge across the Missouri River at Booneville that would make your car seem like it moved 6" each way b/c of the way the steel treads were placed!! You talk about scary trying ta get across the bridge in a hurry AND all of a sudden an 18 wheeler comes on the deck before you make it across... NOT funny at all!! Glad the old bridge is gone!!

pdq67, Higher speeds are not too bad, they still wander a lot, i just dont feel comfortable enough to risk crashing my original 42,000 mile Z28, plus i do not want to wear them out. I have had this car since 73, and believe me i drove it fast back in the 70,s. LOL. It had the original tires on it and it never darted like these repo,s, until they were 25+ years old, and very hard and cracked.
