16-6.50 are 29 inch diameter.(what I measured anyway)
235 75R15 are 29 inch diameter.
235 70R15 are 28 inch.
I wouldn't mind lowering the truck a bit.Does an inch made a difference?
This is a Sunday afternoon truck.
Has any one ever do 235/70 front and 245/70 rear? Is there room?
I'm getting used to the seach button.
Cheers to all

Does an inch make a difference in what?
Obviously, an inch is an inch. It's a half inch on top and a half inch on the bottom. Which really means a one inch shorter tire will be a half inch smaller all the way around. If you want the truck lower, it'll be a half inch lower with the shorter tire. It also won't fill the wheel opening as much, so it'll actually "look" taller. The larger your first number (ie; 235/245) the wider the tire gets. That means you need a wider wheel to go with it. Now you need to start thinking about your offsets to make sure you won't rub somewhere.
Does an inch make a difference? It all depends. What are you really trying to achieve?

What has been done already? easiest way to lower your truck a couple inches and improve the ride at the same time is to remove every other leaf out of the springs. Using a lower aspect ratio (the tire width vs the height i.e a 50 series has a lower aspect ratio than a 70 series) gives you a tire with a narrower sidewall which can lead to the "rollerskate wheel" look and a harsher ride. A truck usually will look better with a higher aspect ratio tire, something in the 60 -70 series.

Gosh, sorry.
Hi 52 Merc,
The goal on this 51 Merc is to keep it stock,but for a couple of changes.Dual exhausts which I had put on 40 years ago after the original wore out.The other thing would be to give it a hot roddy look when the young lad pulls a float in the parade.I was just thinking of the old days 1967 etc when it was redline's F70's G70's rear.
The 1/2 inch isn't going to make that much difference,but add that to the collapsed springs and it will help.
Thank's AXracer,I knew some one had figured it out.Your savin' me a bundle,I don't have to get so many springs re-arced!

??? I don't quite get the relationship. If your springs are in that bad of shape, tou'd be better off buying some new lowering springs. I would never pay someone to re-arch old springs for me, I'd buy new or do it myself. How far are you from Julie, her spring shop did a good job on hers.

Also, the tire size difference you are talking about might look a little weird from a profile standpoint, but as far as roll out distance of the two tires, the smaller one will increase your rpm by about 200-300 at the same freeway speed as the other tire.
The 15" radials will be about 35% less expensive.
I bought a set of 235/75R15s for the back and a set of 215/75R15s for the fronts of my F1 and it was a super choice. I got them at discount tire and spent about $450 on the set - mounted/balanced/installed with lifetime road hazard warranty. They ride great and I'm very happy with them.

OK, so you'll be swapping them back and forth when desired, makes sense. Just was thinking out loud, that 16" wheels are a lot more common with the inner nubs for the caps, than 15". As for springs, if you want lowering springs, I've looked at Posies dual springs. They are a bit safer than monos. I also planned to add a couple shorter stock springs onto the Posies to bring it back up a bit for less drop, and still give it truck usability.
