Steering issues

[jgreg53]

I'm discovering that if I change my tires front to back and side to side in makes a difference in the way the car handles. I'm guessing it has to do with having gone from bias ply to radials. Anyone else notice changes after making the swap?

So do you have all radials at present?.............are they the same size front to back.........also the wear pattern on the tyres and air pressure?........the same all round?............and finally are you swapping a tyre from one side of the car that rotates in one direction to the opposite side of the car where it rotates in the opposite direction and does the tyre have an assymetrical tread pattern?...........andyd

sounds like you are experiencing the early stage of radial belt shift....brand and age factors may apply.  Cross rotation does not do a radial any favors regardless of what a tire salesman tells you...remember, he eats only if he sells new tires.

The tires are coker. Pressure is good. Tread is very good. All the same size all around. I swapped front tires side to side and that helped then I swapped passenger side front to back. That helped more. My reason for trying this was to help a hard pull to the right. The pull would change depending on where I was driving on the crown of the road.

just for giggles...how much weight is on each tire and don't forget to look at the inside of the rim for weight placement....

I have read of quality issues with Coker.   Close inspection for crooked belts,out of round, varying tread depth etc may be warranted.

I've had mostly good luck with Coker. I'm running their bias ply look radials on my '39 Plymouth. On my first set I had a bubble appear under a whitewall after a few hundred miles. Coker replaced it for free and paid shipping both ways. I recently bought 2 more tires from them. My mechanic found one was out-of-round when he tried to mount them. Coker again replaced it for free and paid shipping both ways. I'm happy with the ride and their service, but there have been some quality issues that they made right.

big big difference in tires for show and tires for GO....old molds and old techiques does not make the tire anything but new...not better, not quality, in no manner improved, just basically NEW.  For the trailer queen and many show/parade cars...this more than suits the bill for the build, just got to look right.  This has always been a factor in the hobby, which tires for the look and which tires perform.  Many will never show the car for points and I see the trade off for looks as poor choice when safety and performance is so lacking.  This is why such stores as Diamondback and the White Wall Candy store exists...the come very close to meeting both performance and looks.  Price, compared to a car that does not roll true and one that will, the difference is so little money I could never see old technology on a car rolling the modern highway at speed just to have the right square edge on the tread.
