The Stovebolt Site Forums The Shop Area General Truck Talk Tire size? Do newer sizes fit?

These old trucks ran a tire size, I think was a 7.10 something? Can you mount a tire of a newer size ratio? Not the right size but just as an example like 265/70/r15. Or will this be a problem. Asking before I'm wrong as usual haha?

Yes, you can run just about any size tire. But what year truck you talking about? I owned a 55,59,and now a 61. I'm running 235/75/15 now.

On my 52-3100 I have 215/75/16s on stock rims.

It really depends on what year you're talking about. The older the vehicle the skinnier tire. New tires like wider rims and when mounted on skinny rims tend to rub against tie rod ends and other stuff inside the wheel well. 215 or 205's can be a good choice. If you have 16" rims there are 7.00's for sale out there.

Its a 1952 chevy 3600. thanks guys

Which wheels do you have? According to the manual, they should be either 15" or 17" 2 peice wheels. Either way, modern tires will not work very well with them. I would suggest swapping out to a 16x7 modern single peice wheel with a 3.5" backspace, and use a 235/85/16 tire. That will be very close to the OE size in diameter and load rating.

what is the OE size diameter for a AD 3100 truck?
I tried looking it up with the search feature and shop manual and could not find it.


Thank you

IIRC, it's right around 31", which works out to a 215/85/16 in a modern size.

I looked in my TRUCK DATA BOOK FOR SALESMEN .Tire sizes could be 6.70-15,6-ply , 6.50-16,6-ply ,6.00-16,6-ply and 15"6-ply .There was no info on the tire diameter .That will vary by manufacture from what I have seen.

Thanks for the info.

I didnt have my original wheels.
I bought some new 15x6 wheels. and was trying to maintain correct tire diameter.
I went with 235/75r/15. Put me at about 30".
this was on a 50 3100

Thanks

If you wish to check rpm or tire size go to, www.randysringandpinion.com then go to calculator at the top of the page. it is fun to play with the different sizes and gear ratios.

I have a 1957 Chevy 3600 pickup 3/4 ton dually. The tires are 7.0x17.5 and it seems impossible to find this size tire anymore. I wanted to change the wheels to 17" or even 16" to allow use of standard tires (is this okay?) but I can't find wheels to fit the hub piloted design. I finally found an 8 lug x 6 1/2 wheel with a hub opening that is about a little too big. My worry is the vibration of using only the lugs to center the wheel while there is about 3/8" play aoring the hub may not be the best idea. Where can I find modern sized wheels that fit this older truck hub dimensions? My Chevy dealer isn't helpful and steered me toward specialty wheel shops, but none I visit so far even show the dimension for the hub opening, much less can match it accurately.
