I picked up a couple 235 85 16 Goodyear load range G tires a couple years ago at a swap meet. I have them on the front of my dodge 3500. On the tire it says they are regroovable. how is that done? Maybe they aren't for vehicles, but they are doing just fine. Stan
 
On my FedEx Home Delivery truck, I had a pair regrooved. Was not very expensive, but, on a commercial vehicle you cannot use them on the steering axle. I should have never done it, as the traction over the winter was less than desirable! Also, had a blowout in the summer of one of the regrooved tires. Kicked myself for even bothering!
 
I know that a lot of tire shops used to do that, but didn't know if they still did no not. Your link shows that obviously someone still does.
 
I do know when i worked for Firestone they leased tires on a cost per mile these tires were special
made with heavier construction with thicker under
tread so they could be regrooved with a very deep
tread to get more miles per tire.
ON most regular tires i have ever seen regrooved
they were cut into the fabric, because the under
tread is only a few 32nds deep.
 
I think it's like semi tires and regroovable means the same they can be recapped. They can be recapped but not used on the steering axle. Goodyear does recapping and Bandag is another popular name for retread.
 
only re-grooveable tires I've seen were on city transit buses in buffalo new York, when the tread was worn down they would drind them smooth then take what looked like a power saw and cut a cross hatch pattern in the rubber
 
I thought you guys were all older then me. I remember regrooving tires as a kid. Shoot a neighbor did it up into the late 80's.
I thought you could run regrooves on the fronts, just not recaps.
 
What you are talking about is retreading. Regrooving is cutting the grooves deeper in the existing tread. I do it on my drive tires all the time. I have never tried it on steer tires tho. Regrooving is done a lot on truck tires and I've even seen it on recap tires.

Use a grooving iron like in the link Jon posted. Like others have said, some truck and trailer tires can be regrooved. Back in my racing days we grooved our racing tires with the same type iron as shown in that link. I regrooved the tires on a truck I had back in the 80's and didn't have any problems. I wouldn't recommend anyone regroove tires that aren't designed to be regrooved.
Regrooving is just that. Cutting existing tread deeper with a grooving iron. Not the same as recapping/retreading.
 
please don't endanger your life and others on the road. On a tire that size, the thickness of the rubber under the tread is no longer thick enough to warrant doing this. I don't know why the tire mfg's still use that term, it just lets the recappers know there is enough of a base to support a retread.
 
Some tires are indeed designed to be regrooved. Not endangering anyone by properly regrooving a tire that's designed for it. I think you're confusing terminology used for recapping.
 
You can use recaps on the steer axle, as long as the weight rating of the tire is under something like 4400 pounds.

Not a lot of regrooving going on here anymore. Most of them get shipped to Mexico or South America once they get regrooved.
