The radial tubes have a marker indicating they are rated for use with radial tires. I guess the flex of the radial tire is greater than a bias tire so they have to handle more movement.

Hey Tom,
'differ' Q.....
Yeah, they differ a lot as they are THICKER and built to support the radial tire in its' flexing behavior. Nice piece of equipment and gives nice ride, IMO.

BTW , when I bought my 16 inch steel belt radials from Coker about 2004, I went up to their main office in norcal. I was shown a little device that is used to prevent chaffing of the tube stem from the wheel. It is well worth knowing of this item and it dose its' job well ! My tires are like new yet. Of course, I only have approx. 2000 mi on them, but hard city driving miles

John,
Any pictures of how they look on your Fordor?
Thanks.

I installed the Excelsior radials about 6000 miles ago on my 31 Slant window sedan and what a difference! car drives like modern now. On the way home from a car show this past summer my left front tire went flat and because the sidewalls are 8 ply the tire was like a run flat! no kidding. I was able to very safely pull off the road. The reason for the flat? the new tube split at the seam! anyway the Excelsiors are well worth the money. If you are considering new tires drive someones car before you purchase and you may want to spend the extra bucks. My total tire cost was $1,174.00 with tubes from Mac's

I also have the 19" Excelsior Stahl Sport Radial tires from Coker on my 1931 Sedan. (I also purchased the required radial tire "tubes".)

They are great; much improved handling/steering/stability over bias ply.

Cost is twice that of bias ply tires but they are supposed to have twice the treadlife; I cannot yet validate that claim.

I've had them for 3 years/6000 miles and they show no obvious sign of treadwear so far. I will buy them again when needed and I highly recommend them.
