Re: [Chrysler300] 61 300G

Hi Val - Nexen is Korean, and Toyo is Japanese. I know nothing about Nexen but Toyo have supplied original equipment tires on Japanese cars for over forty years. They're decent quality but not the best available.

Diamondback do not make tires, rather they take tires made by brand name manufacturers, remove the sidewall, and essentially vulcanize a replacement sidewall onto the tire with the design the customer wants. The tire they start with is driven by which manufacturer(s) make the tire size your car needs.

I have Diamondbacks on two of my cars, Michelin on the brand X GS455, and BF Goodrich TA's on my '66 300. BFG was the best manufacturer IMHO that made 225-70R14's for the 300. Both sets have performed well, although my cars aren't driven much, or hard. The tires on the GS are 9 years old and have about 3,000 miles on them, showing almost no treadwear. They hold full air pressure during 6 months of winter storage here. Tires on the 300 were new this spring with only a few hundred miles so far.

Diamondbacks are pricey because obviously you're paying for the tire plus their cost of replacing the sidewall. However, the upcharge for a better quality brand is probably not that significant, and worth asking them about.

Spoke with James at Diamond Back this afternoon and he stated 235!75 R15 was the correct size for a G. He advised of brands: Nexin & Toyo. Never heard of either one. I suppose they are made by a major company?

I second Michael.  My Diamondbacks are for superior to the Cokers I took off.

I have Diamond Back DB2 radials 235/75/R15 with a 3" white wall, same size whitewall as original tires. If you want the original look of bias ply tires then they offer those too. If you plan on driving the car I would go with the radials, I am very pleased with mine. They usually have a holiday sale with $50 off each tire if you can wait till December

8.00-15 nominal diameter 29.3 to 29.7 inches (variability by brand back then).
I think Coker now has some 8.00R15 vintage looking whitewalls not sure sidewall width, but 1961 was last of the wide whitewalls and they had gotten progressively narrower by year til they went to narrow white in 1962. There may be some better experts here, but as first responder, I would guess about 3 inches - not much wider.
225/70R15 (nominally 27.4 inch OD) equated to G70-15 or in your vintage 7.10-15.
227/75R15 (28.3 OD) H78-15 or roughly 7.60-15; 235/70R15 (27.9 OD) H70-15 (same load as 225/75R15 or H78-15)
235/75R15 (28.9 OD) J78-15 or roughly 8.00-15 - still slightly smaller OD and radials even at higher pressure will have lower static loaded radius (shorter sidewall with more bulge at bottom).
Best, Ed

Hi All,
Now that I've sold my 61 Corvette my 61 300G gets all the attention!
1. What width size whitewall did the 300G come with?  I'm planning on buying Coker radials, The stock size was 8.00 - 15.  Would that equate to 225 70R-15?
2. I also need to do the brakes from stem to stern.  I was going to use NAPA for most of the parts.  Comments?  Recommendations?  Has anyone used s/s brake lines from Good Brakes or Brake Hoses Unlimited on EBay?
