Rims for Radial


Donnadodge

Recommended Posts

I have used this site countless times to solve issues and is amazing.  I would sure appreciate any help on the following.

 

I own a stock 1947 Dodge P15 (Cdn Club Coupe) and is hopefully going to be my regular driver this week. (have done lots of work)  This car as purchased has 15 x 5 1/2 JJ rims with old 215/75R15 radial tires.  I purchased new 215/75R15 michelin Defender LTX M/S tires and had them installed on the rims.  The front rims had a spacer installed between the hub and the rim.  The Spacer is 9 mm thick. (23/64th inch).  I then realized that this Spacer takes up about half of my thread make up on the hub and is not very viable.  Plus, I put the new tire/rim on with the Spacer and the tire is still too wide and hits the top arm assembly on the nut anyway.

 

I believe I have looked at most of the threads and there seems to be no problem with the rims being used and that this size of tire should be OK.

 

Just wondering if there is a rim designation or code so I can by new rims that will solve this problem.  Any thoughts appreciated.

 

This one has really got me!

I don't know if this will help or not but I had 15x6 Wheel Vintiques Chrome Smoothies with 195/65 x 15 Coker Radials and 15x7, 235/65 x 15 front and rear and had no clearance issues front/back, inner or outer..........for me 215 size radials are too wide for 5 &1/2 rims, I would not run more than 195 width tyres..........andyd

Hello Andydodge

 

Thanks so much for the feedback,  your 41 Plymouth looks so great.  The body shape of the Mopar coupes are the best out there,  my opinion.  

 

As an update, I placed the original 16" rim and 6.00 - 16 on the front and checked the side clearance.  The clearance between the tire and top arm assembly is only about a 1/4 an inch or so.  This seems tight for being the stock build for the car.  To me the entire front-end looks original but is there something that maybe is letting the tires turn too far.  Seems like a long shot but thought I would ask.

 

Also,  just wondering if you would know off hand what the backspace is on the rim you have for your 15x6 Wheel Vintiques Chrome Smoothies.  

 

Just for info:

The 15 x 5.5 I have has a backspace of 3 3/4".

Just for fyi, the original 16" rim has a backspace of 3 1/4".

 

What gets me is that with the 15 x 5.5 with a 3 3/4" backspace I basically need an extra 3/4" or better 1" clearance.  This just seems odd to me.

 

Any additional thoughts would be greatly appreciated.

 

Randy

Unfortunately I sold the Plymouth........like a dope.......lol...........still got the 40 Dodge Sedan tho'........the Wheel Vintiques were the standard backspace which I think was no more than 3" but thats just a guess as I can't be sure..........the Dodge has 14x6" alloy mags on the front as shown and neither car has had an issue with the tyres hitting inner suspension parts or outer fender wheel arch openings...........do you know what your rims are from?..........also you mention hitting the upper camber nut..........which indicates on hard lock or turns..........the stub axles on these cars should have a steering lock adjustment bolt that screws into each inside or suspension side of the stub axle and is adjustable to limit the steering lock on each side plus this bolt has a lock nut to lock the adjustment ........does your car have these "bolts".....in the attached pic this adjustment bolt is right in the center of this pic and in hard turns touches that triangular "boss" that projects out from the spindle...............lol.............does this make sense...............if your car doesn't have these you can make do using a 7/16th UNF bolt, ideally a hex headed cap screw would be better........or the correct thing.........lol..............BTW is that backspace figure from the inner or outer rim edge?...............andyd.

Thanks so much for your reply.  That is a great idea and the picture was a great help.  I took a look and I have both steering lock bolts.  I measured how far out they are and compared it with my 1947 Plymouth coupe. 

 

1947 Dodge Club - 15/16" and the 1947 Dodge Bus. Coupe is 7/8".  So this seems to be ok but was a great thing to check.  

 

The 3 3/4" Backspace of the 15 x 5.5 rim is from the outer rim edge.  To confirm I cut a board and placed across on top of the steel rim (highest part) and then measured to the wheel mounting surface.

 

You mentioned the that the 5 1/2" rim is a little small for the 215 and I was concerned about that as well.  I did check the michelin specs of this tire and it says that it is has a width range from 5.50 to 7.00.

 

From what I have read on this site, people use the 215/75R15 with a wheel size of 15 x 6+, bolt pattern 5 x 4.5, backspace 3.75 with a center hole of 2 3/4" and it works just great.  I just don`t get why I am having this problem.  One thing I will check tomorrow is to put the 215`s on and take the car off the jacks.  Just thought about it and maybe that will solve it...  Any other ideas is appreciated.

 

On another note, I am in Canada and I have a 1940 Dodge businessman coupe.  The thing is that the Canadian Dodge was basically a Plymouth from the US.  Someone can correct me if I am wrong.  The dash for example is very different for a US Dodge than a Canadian.  I noticed you are in Australia and was wondering what Dodge you have or how it might be different.  Yours is a beauty.

 

Thought I would include some pictures so you see what I have been working on.

 

Ps.  The 1947 Dodge Bus. Coupe has plymouth front fenders.  (it was not me) hehe

My  1940 Dodge is an Oz assembled car, body is by TJ Richards the Oz body builders, here they used the Plymouth chassis, fenders, hood, lights etc with Dodge grille, badges & RHD dash...basically what was done in Canada.......tho' there were a very small number of Oz 1940 Dodge cars even with the plymouth style body but with the US Dodge fenders, hood & headlights...the attached pic is one such car...............andyd

Thats great info and thanks for the photo.  I do like those vintage shots.  Before the internet I told a fellow at a swap meet I needed a radio grill for my 1940 dodge coupe.  He said he would ship it to me at no charge.  Amazing!  When I received it I thought he must have misunderstood the year or make or something because it sure didn`t fit my car dash.  I finally found out that it was the USA radio grill.  Hehe!

 

I really need some help on this tire/wheel issue for the stock 1947 Dodge club coupe. (Going to be my regular driver hopefuly next week)

 

Question:  What P215/75R15 tire (make & model) plus Wheel (make and model) will fit this stock 1947 Dodge (cdn) club coupe.

 

IF I COULD RECEIVE THAT INFORMATION I AM GOOD TO GO!

 

Considerations/Concerns:

 

Hoping I do not have to use a spacer/adapter.  Maybe this is the only option regarding how other mopar fellows are able to make the P215 fit.

 

I mounted P215/75R15 tires on a 15 x 5.5 wheel and did not have clearance.  Note: Even with the 1/2" spacer that came with car it was not very viable. Plus I lose 1/2" of bolt thread make up into the hub.

 

I mounted a stock 6.00-16 bias tire with 16 x 4 wheel and only had 3/8" clearance.  How can a larger tire fit?

 

I have taken photos of the fit issue to hopefully solve this problem.  I have broken it down with pictures and some key details.

 

1st - picture is of the front left steering, suspension, etc. (issue area spray painted silver)

2nd - picture shows stock 6.00-16 bias tire with 16 x 4 rim - backspace of 3 1/8"

3rd  - picture is of 16" rim with 6.00-16 tire showing clearance to brake clip of about 3/8"

          (note: clearance between top arm nut to tire is about 3/8" as well) picture not shown

4th - picture is showing full turn right with 6.00-16 tire on 16" stock rim (just thought it might help)

 

Will send additional pictures on next submit right away.  Any questions or clarifications, info greatly appreciated.

Last photos to help me with wheel and tires:


5th - picture shows a P205/75R15 on a 4.5x15 rim - Backspace of 3 3/8"

6th - picture shows P205/75R15 on a 4.5x15 rim with no clearance to brake line clip

7th - picture shows P205/75R15 on a 4.5x15 rim with 1/8" clearance to top arm assembly

 

I guess I am kinda back to what wheel and tire (make and Model) for both that will work on my stock car.  Then maybe all this math stuff is not required.

 

I really need some help on this.

 

Tks Randy

This has me intrigued............does it scrub on both sides?......have you tried to adjust the steering stops I mentioned to see if that helps?.................does it only scrub when the car is on the ground....or only when off the ground.......or both?................does the car have an excess of toe in?............andyd

Make sure you are checking clearance with the tire on the ground and fully loaded. I was concerned when I first got my P15 as the front tire was scrubbing as shown in your photo when turned full lock when I had it on the jack and checking out everything. But when it was off the jack the clearances were fine.

Thanks for the replies.

 

I know I put the car down with the P205`s and believe the clearance issue was the same for left and right but did not document.  I will do that tomorrow and report back.  I checked the steering stops and compared these with my other 47 business coupe and they are pretty close so I am assuming what they are set as is normal.... 1947 Dodge Club - 15/16" and the 1947 Dodge Bus. Coupe is 7/8".

 

Just wondering what rim and tires you guys are running with as I could look the specs up to help me understand what should work.

 

Thanks again for the support.

Does it scrub with the tyres on the ground at normal road height? or only when the car is raised and the suspenson or upper A arm is hard against the chassis?.............andyd
