Radial verse a Bias tire on same axle

old · Mar 14, 2018

So I am working on getting 6 tires back on this old 1965 Ford 1 ton. Just mounted a good used radial tire on one of the rims with bad lug holes and then put it on the front axle and low and behold the lug nuts seem to have enough bevel to them to get it pretty well centered. The other rim has a bias tire on it and I am thinking about putting it on the other side instead of mounting another radial tire on that rim. This truck is on farm only and might get up to 20 MPH if even that fast.

Rears will have one bias and one radial in each side, side by side.
So will it drive oddly or will it be ok so low speed?

Seriously doubt you?ll even notice

run it, are the mismatched rears the same diameter? might want to match them up if not, might work the spiders some but weight would be better if different diameters.

I've always heard they don't tract the same. Whether that is true or not I don't know. My opinion on the tires is the bias tires are far better than radial and will last a lot longer. I have some on my jeep that are 20 years old and are still good.

Just make sure thy do not hit each other in the middle.

At speeds of 20MPH or less it will be just fine. Doubt you'll notice any issues. Prob'ly be OK up to 35MPH for that matter.
You'll know when to back off.

The bias tire on this truck have been on it for one maybe 2 decades if not longer. Ya there tube type due to the split rims.

old · Mar 14, 2018

The bias rears will be a 7.50X16 and the radial next to it is a 225/70R-16 so yes the bias tire it one maybe 2 sizes bigger so the bias tire will take more weight then the radial will but I figure once loaded the radial will sort of take up the over load

Ah but this Ford probably has less mile on it then the car/truck you drive. It has only 80,898 miles on it and no the odometer has not rolled over

The way I see it radial tires were invented so they could sell more tires. Radial tires usually only last me four or five years before they start coming apart. I had one completely delaminate like a retread one time and it never went flat. I went the rest of the way to work on just the core. I've never had a bias tire go bad before with the exception of being worn slick.

I've had trouble out of both type but then again I have also driven many types of cars and tuck and have something like 1.9 Mil miles on my driving record. I have also worked at a couple places as a tire repair man so again I have seen many tires go bad for some odd reasons

Rich, MO state safety inspection says you can't run a bias/radial mix on the same axle. So if you're taking it to get inspected...

May want to check your inflation pressure... Never lost a radial tire to delimitation that wasn't run flat / way too low on air. We run 3-15 year old used radials until they wear out or get an unfixable flat. Often seems to happen around the same time.

Sounds like you will never drive it on pavement?

This truck has not been on the open road in over 20 years. Kingpins are bad, has no brakes, light do not work correctly and the list could go on.

It runs but that is about all it does. I have to keep it at almost full choke to make it run and that was after I rebuilt the carb. Before I rebuilt the carb it might run but not well enough to do any thing. I think it may have a vacuum leak which I plan to check once I get the upper radiator hose replaced.

Been over 20 years since it was driven more then to the end of my driveway. Hasn't had working brakes on it for well over a decade and the kingpins are bad and the list could go on

I understand completely. Surprised you've managed 80,898.
A Kansas Rancher and a Texas rancher were talking. The Kansas rancher said, "me and the wife have 300 Acres and about fifty head. Not huge by any means, but it's enough to keep us busy."
The Texan replied, "Let me put it this way, if I get up at the break of dawn, hop in my truck and drive west all day, when the sun sets, I still won't be to the other side of my spread."
Kansan replied, "I had a Ford once myself."

(my first truck was a 65 Ford F100.)

Ya I am not a Ford man but seems most car/truck the state of Missouri uses are Fords. Look at most cop cars and small trucks used by cities and state and I bet you will find most are Fords. My dad got this truck back in the 80s and it was owned by the conservation dept. and they sold them when they had 60K on them. He paid $1500 for it. Up till the kingpin went bad it was used on the road but with them bad and the cost to replace figured it was not worth it to put it back on the road

I have been behind a truck with dual radials (2) touching because the wheels weren't dished out enough to support the sagging sidewalls. At 20 mph, nothing much is going to happen so I personally would do it if the economics warranted and with one of each type doubt they would rub and even if they did......20 mph???? Go for it!

As it sits right now the gap between the tires is big enough to slip man hand between with no trouble. But that is also with a 225/79R16 on one wheel and a 7.50X16 on the other one so the 225 does not even tough the ground as it sits. I have a couple 235/70R16 that I plan to put on since they will be a lot closer to being close in size of the 7.50X16s
