wide whites .... Diamond Back ,Coker , Konotia , Calli ...........excuse spelling on second to last . suggestion appreciated .
those are radial sizes. I am no help there. My 40 has 8.20-15's on the back and 5.90-15's up front... good luck
I installed a set of Diamondbacks last spring on my '41 Chevy sedan- 205/70R-15 fronts and 215/70R-15 rear. They really smoothed out the ride and they look great. Hope that helps. IMG_6710A by brokedownbiker posted Feb 8, 2025 at 3:06 PM
Two of the best reasons to buy DB wide whites. The last set of Cokers I had rode like those square wheeled cars in Canada on Southpark. Eh, buddy!
My basic understanding of Coker vs Diamondback is that Diamondback installs a new sidewall on someone else's tire (at least in radial sizes), for example one of their lines uses BFGoodrich Radial T/A tires. Coker makes their own tires using their own manufacturing and rubber compounds, to my understanding. A friend was buying "BFGoodrich" Silvertowns from Coker, and found they wore poorly compared to regular radial T/A's (essentially the same tread pattern). As others have stated, there are other concerns with Coker. I haven't heard a bad thing about a tire purchased from Diamondback.
I have had dozens and dozens of Coker’s with zero issues. All of them were bias plies. I have never had any radials on my cars
I don't know about DB's other tire offerings like those BF's but I have a couple sets of Auburns (both WW and BW) and they are built by DB, their molds...new molds, not worn out molds that produce less than round results. Call down and ask to talk to Bill, as well as all other men named Bill, he is wise, friendly and helpful. I do know he started building a 820 WW Auburns. He didn't make them when I bought me 720 rears as the mold was not yet perfected.
There are Cokers when Cory owned the company, and there are Cokers now..... Many reviews posted on threads here. I like Diamonbacks. I think they currently have free shipping. https://dbtires.com/eblast/2025/20250203/Blast2.jpg
Had a customer in the shop a couple weeks ago that had just changed out a set of cokers on his ride. He said the same as above, badly out of round and drove terrible. He said they were less than a year old and had about 7000 miles on them. Said he thought they might have gotten better if he just put some miles on them but said after 7000 miles he couldn't take it no more and ordered a set from someone else. Another customer came into the shop about 2 months ago that bought a set of used cokers for his 63 vette, again the same thing, he bought them cheap because the guy he bought them from said they drove like crap on the highway because they were so out of round. The customer said he didn't care because he just drives it occasionally and basically to the car shows so we went ahead and installed them. To be honest I'm curious if he starts showing up this summer complaining to us about it since we went ahead and installed them... ....
I’m a “Whitewall Tire Geek”. Have delt with both, Coker and Diamondback. Go with DB Tires. They by far have a better product and customer service. Not cheap, but usually run some type of monthly specials with percentage off or free shipping.
LOL! The problems some of you have with specialty tires is one reason I buy "Off the shelf". I forgo the wide white for rideability. I buy a LOT of gas from the $ savings. The Shurtrac [ china, I know] on it now have around 12,000 miles, and would go that many more I believe. I 1/2 inch ww. Around $100 per currently. Ben
I run Coker BF Goodrich Silvertowns black walls (Available in www ) on my 51 Ford Coupe. They have been great tires.
My 49 Buick has Diamondbacks on it, but they are radials and they ride great. Sounds like Coker can only make a good bias ply tire. All the problems I have heard about are with their radials.
