Are these a good idea?

My back tyre is rounded, don't mind buying a new one but this seems like a good idea when there is still stacks of meat on the tyre.

soldering iron bro. or one of those "craft" hot knives...
good idea?
just be careful.

Back in the day I just used a normal craft knife.
It works well, but a powerful bike will tear the knobs off if you take too much off....

Or a less powerful bike ridden by a fat bastard.

I guess you would only do one cut on a tyre. Had thought of a craft knife. With a bit of water I guess.

Turn the tyre around. Have used an angle grinder but not worth the hassle.

Lol...back when I raced MX i was a skinny (ish) bugger. My KTM250 could stay with My mates 500 in a straight line

With three bikes in the shed I have had one of these I got from the US for about 5 years now.

I would get about three sharp tyres per rotation before having to replace the tyre.

Well worth it. Takes me about 20mins to shapen a tyre.

Yip they work well, I don't bother turning them around because you then put the crap edge to the back, try going down a steep wet muddy hill, its about then you realise that adrenaline is brown and it wasn't such a great idea.

I cut my S12XC three times and at the end of that it was completely F&%ked, third time around was on volcanic rock which is like riding in a cheese grater so it finished it off fairly quickly

BAck in the olden days that was a way to get 2 meetings out of a tyre

I used to use a dangerous method, but the Knobbly knife actually works well & encourages you to ride on better edge more of the time than holding off on buying a new tyre.

Starts raining the night before a big ride? least you can get out in the garage & give yourself a chance.

NZ ones come with NZ plug & 240v of course.
