Model T Ford Forum: Forum 2015: Flat Spotted Tires "Fixable"?

I bought a set of 21" tires a couple of years ago that I believe were on a car that sat for a considerable amount of time. I assume they are flat spotted. Is there a way to fix them?

Where they inflated while they sat.

Depending on what they are made of they might recover if driven on a hot day at speeds that will heat them up even more. It's worth a try.

In olden days,some tire stores could "shave a tire" I don't know if they even have that equipment any more.

The last time I had to have a set of tires shaved, the only place left to do it was a 4x4 truck shop, they still did it for the "monster truck" tires that some folks buy.

The other 'fix' is to rotate them, one at a time, to one rear wheel position and spin the tire while that tire is jacked up off the ground. Lower the car, by means of a hydraulic or screw jack very slowly until the tire barely touches the ground. Best results are achieved lowering the tire over concrete. Make sure the car's other three wheels are safely blocked to prevent car from 'taking off'. Continue lowering car until the high spots are ground away and tire is relatively smooth. For additional safety, do this with a buddy with one of you in the driver's seat to stop the car in case the car's blocks, fail. My Dad and I did this in the seventies with some new Allstate 21" tires that were out of round, and although a lot of rubber was lost in the process, we finally got them to a tolerable state of trueness. Letting the wheel spin with the engine at idle and the trans in high will spin the tire fast enough to remove the rubber. I have been to tire shops that have a tire machine that is half balancer/ half lathe, and they do the same process, but with the wheel and tire off the car.

My T tires get a little flat spotted after sitting all winter. After a few miles of driving however, it goes away.

I bought the tires at our local steam and gas show in the swap area. The tires look really good. I talked to a member and he said the owner restored the T and changed the tires due to the age and sitting. I have no idea how long they sat in one spot. I have had them in the rafters of my shop the last couple of years and it really gets hot up there in the summer, so maybe that has helped. BTW, I do have a local garage that shaves tires, so that is a option.

Thanks everyone.

If they are nylon that's the case for them, will probably smooth out within a few miles unless they are cracked where they sat, then probably blow out. KGB

I'd mount them, inflate to 60 psi and lay them in the sun for a few hot days.

...and at the end of the driving year I would put the car on stands and deflate the tires by 1/2. Just my .02.

Lol in the 90's my buddy had a T he stuck back together using unrestored swap meet and "pulled off the spot where they sat for 50 years" parts including many old tires that had hardened to the point they didnt need any air needless to say taking off in that thing with the dry rotted spokes creaking away was exilerating!recently helped a friend move a dump truck that sat for twenty years when he took off i thought it would bounce right off the road but by the end of the run it smoothed out

I would run them like they say. If you shave them to the low spots, and then they relax again, you'd have high spots, and the bounce back again.
Tire shaving is for out of round tires, not flat spots.
