what kind tires does these use? it only say 170 and something 16. it's all stock wheels. what profile can i fit?

 

The origanal tire size on this truck would probly be a 750-16 bias ply tire which maybe hard to find but you can replace them with a 235/85R16 10 ply radial tire same hight and width just more popular of a choice or for a wider tire the same hight a 265/75R16 8 or 10 ply radial but would probly require a wider rim do to the popular 6 inch wide stockers 7 inch is the perfect replacement rims for your truck.all of these tires are 31.70 inches tall. as to what the truck is if there a five lugs you have a f100 If it has 8 you have a 250 but this tire sizing most likely indicates a 250 most 100s came with a h7815 or a 70015

 

What kind of truck are we talking about?

 

i got a all stock 69 ford f250. the tires said metric? 170 and 16 something, never heard of it... werid...

 

The sales literature shows 8.00 X 16.5 (8pr) as standard on a 6 inch rim. Its very non specific about options, which means nearly anything could probably had?

8pr is "8ply" ?

You should talk to a tire store but I'm guessing that a 225 or 235 / 85 / 16.5 is a pretty close conversion.

You should double check that you have 16 or 16.5 rims (the tire should say "mount only on -- inch rim") and the rim should have a stamping somewhere that says 16.5 (or 16) X 6 (posibly followed by some letters)

 

On my 72 F250, I have 16.5 in wheels. I bought the truck around 75. However, I think the OE was 16 inch wheels. I have thought about finding a set of 16 inch wheels and changing tire sizes when my current ones need replacing. This would kind of relate to the tire size question because I would then be looking at a differant tire size than what I currently have.

My '72 F-250 also has 16.5" wheels and I know they were OEM(we're the original owners); I believe the 16.5" wheels were part of the Camper Special package but I'd have to check the invoice.

 

Mine wasn't a Camper Special so that is probably why the 16.5 inch wheel didn't show up in my Owner's Manual. I do have the original spare on a 16inch split rim and even the tire! The guy I bought the truck from bought it new in Houston, TX and switched to the 16.5 wheels because he had a pickup camper and that was a popular wheel for that application at the time.

A freind just got 6 8.00X16.5 Dunlops from the tire rack for his (ford) motorhome.

In the 80.00 each range.

Decent looking tire.

The 8pr means 8 ply rating. It's an older type of load rating as opposed to B, C, D, E, etc... load ranges. If I recall right, 8-ply typically is D-range and 10-ply is E-rating.

You might check out TireRack.com. Tires are usually cheaper than the dealers, mounting is extra but depending on your state, you can save big on sales tax.

Gene,
I notice you have a 68 f 350 dually flatbed. I also have a flatbed dually and have been trying to understand why mine shows a gvwr of only 8000 lbs on the spec plate inside the drivers door. I once saw a list of variations on this model and apparently I actually have a f351 or f352 which has a lower gvwr than the f350.

I am curious what the 10000lb trucks have that the 8000lb trucks don't. Mine seems to handle 10000 to 11000 lbs total weight without any trouble and the only warnings I have ever recieved while getting loaded were to ensure my tires load ratings weren't being exceeded.

I think I am running the previously mentioned Dunlops with "E" load rating and if I recall correctly they are good for 1950 lbs a piece in a dual configuration so I haven't worried about the weights I have been carrying. I just don't know what my truck lacks to be rated as a 10000gvwr.

Thanks for any ideas
Karl

 

It may be limited by the axle- bearings can only take so much-just a suggestion....

 

hi karl,
i look at my plate on the door ans my say 12,000gvwr, and i got a class 4 window sticker on her, cause of that 12,000,
till you replyed to my post i never heard of a f351 or f352 before this, i going to ask my ford friends to and i will get back to you,
gene

 

Gene,
I am a bit envious of those extra 4000lbs. I am baffled as to the differences. I am assuming we have the same frame, brakes, and drivetrain. It is hard to imagine that much difference in GVWR-- in effect you can carry twice the payload I can legally.

Thanks for the reply and please do let me know if you can find any more info.

Thanks,
Karl
