The problem for me is I know Michelin are so much better than all these other tires in speed rating and performance that I have a hard time not going black wall and getting the best engineered tire made . Probably also the safest and it lasts 60k . The past few sets of Michelin I bought needed zero weights. None at all . That says volumes about precision manufacturing . Diamond back was supposed to put whitewalls on Michelin , but unsure if that hurts them in any way . And I love you tomorrow applies to them. So we have looks vs real performance . I kind of like the look of the Andy Granatelli F going 180 on blackwall moon discs ( ok you can stop laughing ) Or the Kiekhoffer B . On Imperial wheels. ; lately I put “trim rings “ on larger black wheels and was looking at some way to mount F gear in middle ; this also allows 16” or 17 x 8 or 9 wheels and tires and a whole host of improvements in the way the car drives —with lower profile tires of about the same OD . Growing up in the era , wide whites were associated with Buicks and Cads . Chrysler had real race tires , Blue Streaks . Not wide whites. 409 or max wedge were black walls and dog dish. I guess it is the image one wants for his car . Zero criticism , just thoughts. I like the race heritage more than Luxo barge look of a Buick ( or New Yorker ) . Like the race B look too . Last —weights can balance a tire rotationally any where ( add weight to place that is light , you can do yourself on the car ) — all they had , generally, in 60’s ... but if off axis in and out of the plane of the center of gravity of the tire ( and imbalance typically IS in and out too) you add a new problem you can envision as a “wobble balance “ in and out while having a perfect rotary balance . So splitting is best or computer tells you the split % ( on a special spin balance machine) . That said if you need no weights you have no wobble . And even more of “ that said” most of my cars have American Classics especially C, D . If I had one , E. But F starts a new period... to each his own is a great part of our club — I remember some early days performance prone characters ( Chic Kramer comes to mind) who drove fairly ratty 300’s hard —on black walls, and their 300 was a lot faster than yours . George was a bit like that . I get that, and like it; but sadly cars are ? too valuable now.. maybe. Best day of my life was when 62 H turned the fastest time at 62 NHRA drags ( 12.9!) , besting 409 Chevy and 421 Pontiac .with an automatic! First 727. ( lost to Pontiac in the last race , guy was asleep at light) That is a 300. Big heavy and for real fast . Chrysler engineering prowess . Sent from my iPhone not by choice
For appearance sake, I directed my tire guy at the time to mount all weights on the inside of the 15” OEM Motor Wheel wire-spoke wheels. H said he would, but the wheel would not be dynamically balanced. I ran those old Bias-ply Remington’s a lot of miles at high speed and never felt any pronounced out-of-balance sensation. I believe the computerized wheel balancer directs the technician how much weight and where, ,including inside or outside. I don’t understand the physics of splitting the weights inside and/or outside but there must be a good reason. Tire and wheel guys: What, if anything do we lose by placing all weights on the inside? And, why split the weights inside and out anyway? Rich Barber Brentwood, CA 105F today. Curtis and Group, One final 'road-tested' comment from me re the 235/75R14 American Classics I'm running on my 300-F. Just drove back to Chicago from our wonderful Minneapolis Fall Meet tonight - have now put 4,300+ miles on my tires since having them mounted on the F's stock 14"x6.5" steel wheels in April, a few days before heading down to Texas for our Spring Meet. Homeward bound through northern Wisconsin, with strong crosswinds and torrential rain for 100+ miles tonight, in addition to the heavy rains I encountered for a good part of the trip to/from Dallas, these tires have performed very well. There's no sense of fighting the car to keep it stable through these heavy downpours. I'm very happy with their performance. I purchased my 4 tires through a Coker special promotion at a Mecum auction last fall - cost including free shipping and road hazard warranty was about $1,040. Whitewalls are 2 1/2". If your purchase them, be sure to read the online instructions for mounting - including the recommendation that wheel weights be only mounted on the insides of the rims, so as to not blemish the whitewalls.

First I will list 8.00-14 as it evolved to P215/75R14 (P/225/70R14), noting that P215/75R14 is largest 14 inch whitewall (Narrow White) in current full scale production as of 2019. (Hankook Optima H724 price around $65-80). There are other specialty tires ($200-300 range) including 8.00-14, G78-14, and P215/75 R14 including wide whitewalls, but for the most part these are limited production specialty runs, in some cases using outdated equipment. There is also an American Classic in P235/75R14 in whitewall (Wide and Narrow White?). I will note that in early days, to provide a soft ride, tire design was based on 24 psi, frequently with note in fine print to increase pressure (up to 32 psi) for sustained high speed or increased load. If I recall correctly the 24 psi assumed driver plus 2 passengers and 1 suitcase. Anything more moved you to higher load. And Speed limits were mostly assumed to be 60 mph. Later load capacities were based on 32 psi, and most current standard load range radials are based on 44 psi - so dont assume load ratings are directly comparable - and it your rims are old beat up rusty things, dont assume you can go to 44 psi safely. Also, belted and later radial tires tend to have more flexible sidewalls and give lower ride height for a given diameter. This is reflected in the SLR (Static Loaded Radius) column if I had any data from manufacturers data sheets. Most likely your 8.50-14 had a SLR of about 13 in, while a P215/75R14 would be closer to 12 inches and even the P235/75R14 is likely to be only 12.5 to 12.6 inches, hence lowering the car about a half inch despite being oversize to the P225/75R14 equivalent to the original 8.50-14 Second I will list the 8.50-14 to P225/75R14 specifications as these are more likely applicable to C-body cars. Unfortunately the last P225/75R14 I know of were produced by Cooper in 2006. Lastly I will provide data for 9.00-14 to P235/75R14 - again, I believe the American Classic is currently available in the P235/75R14 as of 2019.

Well, that's an easy decision, my 65 300L is original from front to back & I was hoping to keep the wheels & hubcaps!!! Amazingly after sitting for 25 years in a garage, it still has original bias ply tires.
