O/T F100 tire size

I am in the process of getting my Dad's 64 F 100 back on the road. It has 700-15 tires now. What would be the tire size, with today's metric numbers. Thanks Stan

Stan, I am driving a 1981 Ford F100 with the original rims. They say P235/75R15 108T. I hope this helps Ellis

This is a guess but I would say 235R75x15 would replace them. 700x15 is bias ply.

Metric conversion 25.4mm to the inch. 7 inchs = 178mm. Bias profile is about 95, most radial high profile is 85-as in % of height to width, and basics are 80 profile with newer 75 profile fat large ground contact patch and perfomance at 60 with spoked wheels, wide rims, firm ride . Wheel rim width is maybe 5 inches instead of newer 5.5/6 inches on original wheels- take a look at 205/215 LT(=light truck) tires and see if total mounted diameter is close to same so won"t have minor speedometer error and fender clearance problems.

If you're going to bother, why not answer the fella's question politely?

I have a 1990 F150 with 15s on it. They are getting hard to find

The 235 75 is close but a bit smaller in diameter, about 1 1/2" and 2" wider, the 215 is smaller yet with a 205 being about 4" smaller diameter. have all sizes here but not able after surgery to go out and measure but trailer I am repairing changing from 235 to 7:00 and it will stand about 1" higher off of ground. The 7:00 x 15 truck tire is the same size as the 7:60 x 15 implement that was a standard for years and that may give you a close size for them and there are size charts on the net for the truck tires.

Stan,


235R75-15 looks to be the closest for diameter. It will be wide in the tread and at the rim. Might want to use a newer, wider rim for a better fit.

Also, please think about using the type of tire the truck was designed to use. Bias ply tires, constructed of modern materials are pretty good. Your truck will ride better, be easier to steer, and put a lot less stress on the steering gear.

I have several older cars, and the two that don"t have bias ply tires will be getting them when the radials finally wear out. I have a "56 Plymouth that I can"t drive around town because it is just too hard to handle in a parking lot. Swapped wheel from my "50 Dodge (bias ply) onto the Plymouth. Only one hand needed on the wheel in parking lots. It is the increased width and sidewall flex that makes the steering hard. The Coker radials that have a narrower tread are OK. Those were on my "48 DeSoto when I got it. Their diameter and width are closer to the original bias ply sizes. It steers pretty good and rides nice. Tires look "right", too.

And as others have said, 15"s for these applications are getting harder to find. I needed 15" white stripes for my "72. Hankook was the only brand I could find here. So far, seem pretty good.

The right tire is always a hard decision that is complicated when they are for on older car or truck.

700-15/ 215-75-15,,,,,,,,,,,775-15/ 225-75-15,,,,,,825-15/ 235-75-15,,,,,,,,,,now if want to fancy it up, get the newer rims off f-150 and put LT 235-75R-15,,the radials will give a good and handle the groves in the road that old trucks wounder back and forth in... if you don't want to put on LT [light truck} tire s on if not going to haul weight, michelin tires are a stronger sidewall tire that will also handle the groves of the roads..

You can still buy the original 700x15. I bought some not too long ago....course they were made in China (Shield brand) but excellent, excellent tires. Do a fabulous job of resisting dry rot/cracking; if you want to keep it original. I have a full service 4th generation local store that has survived all the latino and big business influx. He does OTR truck tires, motor homes, implements, tractors, auto's, small and large trucks, small and large trailers, go carts, and lawn mowers.....no bicycles buttttt: If you need a tire if he doesn't have it he will get it for you.

HTH,
