Tyre Regroovers

[PhillipM]

I wouldnt imagine a worn tyre has enough meat for regrooving? Is the carcass that thick before the cords?
Thicker it is, the more heat, so I cant imagine truck tyres being designed for it unless its retreaded...?

Sod cutting bike tyres, hardly anything between the tread and cord. Im quite happy riding some rears until the cords showing but thats different!

No, there isn't, and tbh once you get to the wear markers you're on the structural layer of rubber - it looks about the same but it's much harder, stiffer and slippery af in the wet as it barely has any hysteris, it's the layer you often see have microcracks in it in the bottom of tread grooves because it's so much stiffer than the usable compound.

tires that are re-groveable are marked on the side wall as ,,,, re-groveable they are made that way and marked that way ,,,

I have a set of tyres that could be re-groved, just wondered if it was a worthwhile investment before I attack them with the angle gringer!

I have the same unit, bought it secondhand to do some forklift tyres.

Make sure you have some spare blades and be aware if you activate it when not plunged in rubber the blades get hot and destroy themselves pretty quick.

You need to be a bit sensible about recutting treads, better to test gouge a tiny bit of a tread grove to see how deep the cords are and back off a few mm from that.

Blades also come in a few different widths, worth getting a variety. Pro cut are a decent make.

Work pretty well but good luck on making a nice even pattern that doesn't look like you have been at your tyres with a regroover.
I lent it to a lot of people over the years.

how many ended up in the hedgeback with burst tires

@8ob is it cord cord or wire?

I suppose its really the belt, I always set the blade depth deep and test cut a mm or two as deep as I can go. If you hit the belt back the blades off a few mm.Worth practising on a few old tyres before cutting something you want to run.

It's good fun, I went all over a couple of scrap tyres just playing, sad but true

Most (car) tyres have a layer of polyester cords (cap ply) over the steel belts, very few don't. I’d imagine truck ones are the same but I’ve never built them, only ever built car, van, 4x4 and trailer ones.

We used to put michelin XZY 7.50 x 16 tyres on landrovers and when they were worn up, regroove them and fit on the front axle of 2wd tractors. They made an already rough riding landrover into a proper boneshaker.

 

[123hotchef]

It's here. Just ordered some wider blades.

Is t that due to over inflating

 

[Trevorleach]

When I was much younger and had no money I cut the front tyre on the motorcycle i had, a VF750FD!

Most truck tyres have 4 lives
New
Worn then recut
Remoulded
Worn then cut again
Then the casing goes somewhere shifty

Not really they are 4x4 rock crawling tyres running at 30psi for road use
