austinsailor Posted September 23, 2012 Report Share Posted September 23, 2012 (edited) My '53 has 4 1/2" wheel and came out with 670 15 tires. I'd planned all along to get Diamondback wide whites for it. Diamondback's chart shows the replacement for 670 tires to be 205 75r15. They have 215 70r15 on sales for a pretty good price. The 215's are very close to the same diameter as the 670's. 205 75r15 are nearly an inch smaller. the 215's are .8" wider than the 205's. I have no idea what the width was on 670 15. Both 205 and 215 call far wider wheels than the 4 1/2" on the Plymouth. I'm inclined to order them. Any thoughts?

suntennis Posted September 23, 2012 Report Share Posted September 23, 2012 I have a 52 car with the 4 1/2 inch wide rim and have 215-75-15 tires that work just fine. I was told if a wider tire was used there would be a problem sealing. If intertubes are used, this would be no problem. Quote Link to comment Share on other sites More sharing options...
austinsailor Posted September 23, 2012 Author Report Share Posted September 23, 2012 I run 215 85r16 on my 4" wheels on my B1B so I'm not terribly worried about rim width. Overall, will I have good luck with these? I think so, but if there are any thoughts to worry about I'm interested in hearing them. Quote Link to comment Share on other sites More sharing options...
greg g Posted September 23, 2012 Report Share Posted September 23, 2012 205 are too short. Make your speedo read about 10 mph faster than road speed. Quote Link to comment Share on other sites More sharing options...

Oldguy48 Posted September 23, 2012 Report Share Posted September 23, 2012 I bought 215/75R15 Diamondback tires for my P15, using the original 4 1/2" wide wheels. I'm running them tubeless, and have had no problems at all. Wayne Quote Link to comment Share on other sites More sharing options...
Niel Hoback Posted September 23, 2012 Report Share Posted September 23, 2012 Likewise, I have 225/75R15's on 4 1/2" wheels, tubeless. Several years, no problems. Probably shouldn't talk about it. Quote Link to comment Share on other sites More sharing options...
austinsailor Posted September 23, 2012 Author Report Share Posted September 23, 2012 Sounds like I'm worrying about it too much. I should just order them and keep on trucking. I'll call them tomorrow. Thanks for all the feedback. Quote Link to comment Share on other sites More sharing options...
austinsailor Posted September 24, 2012 Author Report Share Posted September 24, 2012 Ordered tires today. Those 2 3/4 whites will look soo good! Quote Link to comment Share on other sites More sharing options...
kencombs Posted September 25, 2012 Report Share Posted September 25, 2012 My '53 has 4 1/2" wheel and came out with 670 15 tires.the 215's are .8" wider than the 205's. I have no idea what the width was on 670 15. Any thoughts? FYI, on the older tire sizes the first number is the width, 6.70" wide. section width, not tread. Or 170mm And, I think the aspect ratio is 100, meaning they are that same dimension from wheel tread. I have some 215r8516 tires on a Mitsubishi box truck which are really close to the 6.50x16 on my 56 Dodge PU. Quote Link to comment Share on other sites More sharing options...
