Tire Size-in Radial

[Dennis_MN]

After Reading many posts, I've learned that I should use

1: threaded valve stems and

2: 215/85R/16E Tires

to replace my 6.00-16 tires for my B1B

Actually mine came with 6.50-16 front and 7.00-16 six ply rear.

I'm looking for a softer ride and the look of the 49 pickup with the proper size tire.

Will radials work alright?, there has been some discussion of bias ply.

and is there a market for my old tires. Actually they have less than 1,000 miles on them. The guy who fixed up my pickup must have thought he had a 3/4 ton.

You probably go to a 225 without any problems. I'm running 235s and if I was going to do it again I would go down one size.

Y'all might want to check your old tire diameter before you buy. If you are happy with your top end speed, stay where you are in size. If''n you wanna lower the total ratio, opt for a taller tire. The 215/85 profile sure looks sock from a distance. Wonder what GTK's 235's do for his top end. How tall are they, anyhow? Is is too much of a good thing? Just wonderin' . . . . . .

"Y'all might want to check your old tire diameter before you buy."

I want to run the equivalent of 6.00-16 but the rears are 7.00-16 so measurements are out. The speedo is way off also, at least 15 mph with that big tire. I have to use a GPS to get accurate speed readings.

Dennis I have 21585R16s on my 46. They are great. Very nice looking tires-gives it a nice manly truck look. They do also help greatly with top speed. I'm sure they are taller then the stock tires. My speedo is off too but the 39-47s have a plastic speedo disk thats always broken so mine is self repaired anyways.

Did you have to do anything to the suspension for radials or just put em on and drive?

Put em on and drive is all I did. If it was warm out I'd be happy to show them to you in person but I wont see my truck til april.

[Dennis_MN]

Mine will not be out until April as well. When it takes over my garage stall, the front sheet metal is coming off so I can detail the engine compartment. While it is up on jackstands, I'll re-do the front brakes and change the tires. Hope to have it on the road by the middle of May.

My '49 is a B-1-C (3/4 ton), with the 15" wheels that came standard on it. The standard tires were 7.00x15" 6 plys. Yokohama makes a 7.00x15" D, or 8 ply rated radial, available through Tire Rack. I bought them and the difference between bias ply and radials are unbelieveable, particularly off pavement...although they make a big difference on pavement, also.

I did no other suspension work. The steering is now nice and tight and there's truly no more 'fighting' the steering wheel. The pickup will simply go in the direction it is steered.

My 1951 Plymouth also has radial tires, P215x75R15...the cheapest ones Wally Woirld sells.

If you ever put radials on these old MoPar cars or trucks, you will NOT, no way, no how, ever go back to bias-plys! David :)

The fair grounds lets the cars go usually the last weekend of march/first of april. You're welcome to come see mine after that.

David, Can you tell me how you found the 7.00x15" Yokohamas at Tire Rack? I bought a pair of General 235/75 15 radials that where about $65 each that I put on the front of my 51 B-3-C and like you said, it is like night and day. They where also the only radial tire I could find that was black on both sides. They are 28" tall about the same as a 6.50x15

Vintrader, all I did was go to the Tire Rack website and typed in 7.00x15 and the Yokohamas came up. Cost was between $100.00 & $105.00 each + shipping. The OTD is 29.4". My wife followed me in her car and when my B-1-C speeedometer was on 55 (steady speed), her car's speedometer indicated 60 M.P.H.

The salesman told me there were about 40 of that size at their warehouses across the country and that he knew of no plan to stop offering them.
