Re: [Chrysler300] Tires 300K 15 inch radial wire wheels

Just as a point of reference, I have as a spare in our ’64 300K ram car, an 8.55/14 Goodyear Power Cushion “3T” WSW bias-ply tire. It as a 5/8”-wide white ring 1-1/8” away from the edge of the rim. This is an inexpensive Rayon-cord tire costing $36.20 A/O 1-1-66. http://www.jholst.net/tires-wheels/Goodyear_Automobile_B-198_1-1-1966_ERM.pdf At the same time, an 8.55/14 Goodyear Blue Streak WSW was $54.45 and appeared to have a slightly wider WSW. I recall that the tire manufacturers changed tire-size nomenclature from 8.50/14 to 8.55/14 in 1965 with little change in dimensions. WSW and sidewalls changed often making exact replacement challenging.

The 1964 Goodyear Tire catalog (http://www.jholst.net/tires-wheels/Goodyear_Automobile_PL1964.pdf ) contains 8.00/14 and 8.50/14 WSW Nylon Custom Super Cushion “Blue Circle” tires at $41.45 and $47.55 each. The illustration indicates a slightly-wider “Narrow” WSW (said to be 1”-1 1/8” wide) about the same distance away from the rim. Catalog note: Available for Factory Shipment Only +-Tire Equipped with Sidewall Valve for Optional Use with CAPTIVE-Am STEEL-CORD SAFETY SHIELD

I know Harry is striving for originality, but with radial tires on 15’ x 8” wire-spoke wheels, originality of tires and wheels is lost so might as well go with a good, safe tire that looks good. I’d go with the widest-possible narrow WSW but would not pop for a custom one-off tire just for the sake of the width of the WSW. I do like the concept of a bias-ply look radial but they are not currently available with narrow WSW or in ideal sizes for letter cars https://www.cokertire.com/american-classic-bias-profile-radials.html .

Page 31 of the Diamond Back catalog has a P235/75R15 Auburn Premium tire with a ¾” WSW http://www.dbtires.com/2017_catalog/2017_Catalog_Lo.pdf The 29” OD is even a little larger than that of the 8.50 x 14 bias-ply tires (28.10”) that came on ram ‘64’s. Styled for the 1979 Lincolns and mimicking the Michelin tread style. Pricing is unclear but probably around $225-$250. The black ring around the rim appears to be wider than the ¾” WSW. The catalog is pretty clear that Diamond Back will make you a WSW of the width you want it and, presumably, the right distance from the rim.

I think you are probably out of luck if you want exactly one inch. I assume you have consulted Coker as to exactly what they have - maybe the American Classics or their new bias look radials - I have not checked them. But you also need to ask distance from inner edge of whitewall to rim - most originals were a bit further out than some of the reproduction tires.

As to production tires mostly 5/8 inch to 3/4 inch and white edge 7/8" to 1-1/16" from edge of rim while Original BFG and Michelin of late 60's to early 80's vintage appear to have been 1-3/8" (2 samples - one BFG HT Silvertown 770, other Michelin X Radial).

Nexen N'Priz AH5 P235/75R15 5/8" whitewall, 1" from rim edge

Hankook Optimo H724 P235/75R15 5/8" whitewall, 1-1/16" from rim edge

Toyo Extensa A/S P235/75R15 3/4" whitewall, 7/8" from rim edge

Cooper Trendsetter SE P235/75R15 3/4" whitewall 1" from rim edge

All above measured as mounted in 71 vintage Chrysler 15x6 rims at 32 psi.

(Mastercraft, Multi-Mile, and other Cooper made tires will be same sas trendsetter SE). (Kingstar made by Hankook but appear lower quality). I did not try Milestar MA775 as they are made in China and appeared to be inferior in appearance. Above Nexen (Korea), Hankook (Korea or Indonesia), Toyo (Japan) , Cooper (Mexico).

Two I have not checked Maxxis MA1 and Gremax 5000 but I think those are also Chinese? Maxxis, however, makes a good ATV tire and an expensive (supposed to be good) trailer tire.

You could go to Diamond Back and have them custom make a set of blackwalls into 1 inch whitewalls by vulcanizing on a whitewall but that is expensive and it puts additional stress on sidewall during prep (buffing) and secondary vulcanization. Still may be your only option.

Hi members, I'm still looking for a set of 235-75R-15 one inch radial white wall tires, only found under 1 inch or over 1 inch, tried all internet sites, hope they still make them somewhere. My current tires are gone.

Thanks Harry
