Have you tried searching the forum? You'll find quite a few who are running 17" and larger wheels. It seems like there's one thread titled something like "Show your wheels". You'll also find lots of wheel/tire pictures.

Love the look here! Would you mind sharing the details on the B/S and O/S as well as the tire size?

All stock suspension? Any rubbing issues? Thanks!

Suspension on the front is stock wiith 1" lowering coils and rear is stock leafs. No rubbing issues. In the rear there is room to go wider with more back spacing. Hope this helps. Ryan

17X8 for me. I think many different wheels look great on our cars. It’s very hard to choose.  I put some Bullitts from the late 90s/early 2000s on mine as placeholders during the build because they were very cheap on craigslist. Once I painted the car I kinda liked them so I just left them. If I decided to stop being cheap I’d probably get these:

I’d personally get 17s for the front and 18s for the rear if buying new.

I have the 2001 Bullitt 17 inch wheels with the 245/45-17 tires. With the TCP strut rods and Lower Control Arms, the ride is a bit harsh. I feel every nook and cranny on the road. Now for handling, it is a slot car. The aspect ratio is very important in determining the quality of ride that you want.

A car riding on lower profile tires will have less sidewall-flex capacity to absorb bumps, and will either require softer springs to accomplish the same results, or be bumpier.

I am looking into slightly taller tires or go back to 15 inch rims.

Yep the model T had 20" on some models. There is a model T here that has a spare that does not have a tube in it. I has a series of holes through the tire that is solid to give it some cushion. They have tried to make them in different versions over the years one recent was Twheels. Iire and wheel in one with no air. They had colored tires for a short while doing burn outs left colored stripes so they are gone.
A suspension on an old car is not made for low profile tires for sure. Even adding gas shocks makes them feel like a buggy. Handle better but very harsh ride.
I guess since i grew up then they just do not look right with the low profile tire.
The only good use for the Big diameter tires i have found was to build a bullet back stop for shooting. Went to tire store got worn out junk tires as big as they had. Stacked them and filled with sand great bullet stop self healing.

When a man is in the woods and talks and no women are there is he still wrong??:P

I agree, David. They don't look right, to me a wheel bigger than 17" or a tire with less than a /50 aspect ratio doesn't look right on our cars. Definitely won't handle right without suspension/chassis modifications. You see 4x4 pickups with huge wagon wheels and skinny sidewalls, obviously they never plan on taking them off the pavement.

FWIW - Here's mine running craigslist 20's all around. Sorry don't have great pics as we've been working on it non stop. 20x9.5s in the back with 315/35/20s and 20X8.5s with 255/40/20s up front. With that wide a tire there is still a reasonable amount of sidewall in the back IMO and looks pretty good. The front sidewalls look to thin. It's at stock height so I think lowering an inch or two up there will make that look a lot better. Eventually I'll probably go 18's or 19's with a taller sidewall. 

Personally I'd stay away from 17" wheels unless you know exactly what you want and don't think you will want to tweak the fit as there are just far fewer size options in 17s. 

Also for what it's worth, it handles and rides really good with this setup considering its all stock.

18x9.5 rear

 

I know some had issues fitting 17" in the front due to contact with the ball bearing. Any issues for you?

No sir

Front

4.5 Back spacing with 245/45 ZR17

Rear

5.5 Back spacing with 275/40ZR18

I now have coilovers but had stock front suspension for many years running same combo from the start.

I wonder if the same tires in 17x9 would fit?

That will depend on backspacing. From memory my 18x9s clear using a 1/2" spacer but there is still quite a bit of wheel over the end of the control arm. I don't know for sure but I think to get suspension clearance on the 17x9 would push the wheel/tire out too far.  I hope that makes sense.

All,

After further research, really always continuing, I was looking into taller sidewalls for the 17 inch rims. This is now not a valid resolution. If you look at the mustangs that had the factory 17 inch wheels and tires, their spring rates and shocks (struts) were adjusted to absorb the bumps and grinds of the road. As Carolina_Mountain_Mustang mentioned, the 71-73 mustangs suspension was designed to use the taller sidewalls for more road bumps and grind absorption.

Possible resolutions:

1: Lower the spring rates of the coil and leaf. Not sure if this possible since it maybe a custom order.

2: Adjustable shocks  Like QA1  Stocker Star Single Adjustable SKU: TS402 - Front  and Rear QA1 Stocker Star Shocks TS601

Eaton Detroit Spring offers a wide variety of front and rear shocks for the 1973 model.

I would image Eaton Detroit Spring would have to make you a custom set of springs.

Onward to more research.

For what it’s worth, I have the late 90s 17” bullitts (as stated above), and they came with a low profile tire stock, as you say. It looked odd on the 72 to me. I replaced with taller profile tires mostly because I wanted to fill out the wheel wells.  With the larger profile tires, people have commented they assumed they were 16s. I kinda like that it makes them look more subtle. 
 

I didn’t drive it much with the low profile original tires because they were plasticized and I had replaced the suspension (with mild upgrades and stock springs) so the car needed alignment.  I got the larger tires when I got the alignment. As a result I can’t speak to how rough the ride was with the 90s stock low-profile.  But with the larger tires, I think the 17s look better, they fill up the giant wheel wells, and they feel fine to me. 
 

Although I could see why the models in the 90s had adjusted springs and all with the lower profiles (and lower ride heights...and different suspensions), I would be fairly skeptical if you told me you could tell a difference between the feel of the Bullitts with larger profile tires and the period-correct magnums on my 73.  
 

FYI, my tire sizes are: 

225/50R17 front (25.9" X 8.9")
And
235/55R17 back (27.2" X 9.3")

A slightly smaller one I considered for the back was the
225/55R17 (26.7" X 8.9")

 

These are for stock-eye, 4 1/2 leafs in the back. I do have wheel adapters for the bullitts to fit.

Hello Lazarus,

Nice! I was looking into that direction. Since you have them installed and driven on them, I may again change direction. I have the 245/45-17 all away around and can tell every nook and crannies on the road. Your convertible looking really good! I appreciate the feedback!

 

What brand tire are they ?
