I have been forcing my brain cells to use my tires a bit longer..
as I'm not making high mileage yearly most of my tire sets are discarded with 6-7 mm thread depth after 5-6 years because of hardened non grippy tire surface :-\ and obviusly thats big waste..
in the past I found tire softeners to be a solution , but not practical as I expected..
after a bit of search and thought I found this and wanted to share

yes.. they sand the tire surface and take the hardened part.. and its logical as the surface goes into many heating cooling cycles and faced various chemicals on road and sun factor.. and japanese even build a machine for that..please watch till the end , you can see the difference

and there is a better way also.. as it doesnt heat the surface

Oh somebody shake him, I'm getting old here. ;D He'd be better straightening the wheel first surely?
If your going to bin your tyres early anyway, what's to loose? May as well try it...?

I think he's the boss , the worker's would have to do at least 10 a minute ;D That wheel was wobbling all over the place :o

whyzatden cem? Tyres aren't worth that amount of worry?

my worries were about a very different subect.. I was outside..

Hope not too serious...
, my point was if something is broken and to be thrown away, why not try to fix it? If your tyres are for the bin, you have nothing to loose.
For instance, it would have been good to test this on my old Falkens. See if tread wear/uneven profile was to blame.

Hmm. Watching with interest. It seems the tyres on the Westfield have transformed into Tunnie granite compound during its' recent period of inactivity. That combined with the fact that I've done about 3,000 miles in it in the last 2 1/2 years and none in the last year....
Mmm. perhaps I'll just bin them. ::)

and this is the best maintenance video I have ever seen ;D ;D ;D

seriously sanding the tires can be watched also ;D :y

.. although it begs the question as to why you wouldn't just take it to a private road somewhere, light up the back tyres for a while, swap them with the front and repeat...
.. and if you're going to be that anal about a Scalextric car you need help. ;D
-
Yes, exactly, why not take the car out for a 'spirited' long drive, and do a couple of 'enthusiastic' corners to take a bit of tread off? :y
-
you can also try what we use to use on drag days at avon park...
spray bleach onto tyre treads & good bit of revs dump clutch & light up the tyres bleach sofens the rubber compound & lighting them up (burnout) will remove aprox 1mm tread per 30 seconds, & make them sticky also good for track days too!!
also another way of resoftening rubber is to let tyres down to 20psi & have a short F1 style weive up & down the road that will scrub the tyres on front & heat them up wearing the tread but not to low pressure or ull fk the sidewalls!!
i have also found out that the harder the rubber compound the worse they get when worn, some tyres will do 30k on 1st 3mm tread & only 10k on last 4mm
others will burn the soft 3mm of the tread & go very hard at 4mm & have shite grip & will not wear out but you get pissed off with the grip level u bin them anyway!! (conti are bad for this!!)
tyre manufactures engineer this into there tyres im sure somebody may post a link on tyre sidewall meanings but if i rem the lower the number the softer the tread... 180 220 240 280 320 360 400 etc etc so worth checking when buying tyres i try to go for a 220 it will have even wear all the way threw tread depth... also traction & temp ratings A AA B etc meaning the running temp tyre will grip at its best etc...
i Dont know of anybody in uk sanding tyres but im sure if u jack both rears in the air & leave in 1st gear on tick over you could use a pad sander on them??
Not as bad as me cutting new tread into a tyre with slick edges with an angle grinder to get another 1000miles outa them :-\
-
Only advantage I see is an attempt to regain something approaching the original profile. :-\

It's common to cut tyres for motorsport use. I think in the first instance you can make the tyre work with minimal "bedding in" - i.e. give it a flat profile at the pressure it's working at, and, secondly, if you don't need 8mm of tread (i.e. you're sprinting or hill climbing), taking the tread depth down makes the tread surface more stable and the tyre grips better.

yep.. thats a good idea :y

thats also another factor..
do you know what happens when you cook the meat initially at strong fire.. and than later use a smaller fire..
water inside the meat is blocked by the cooked layer... which is all professional cookers accepted method..
if you do the mistake to cook the meat slowly from the beginning , it will loose all its water, dry up and will not have any taste..
same is true for tires(not for very old tires).. the tire softening agents (oils) evaporate from the compound at outer surfaces more quickly.. when you clean this layer you will have a better softer compund.. of course this process must be optimized and not done within frequent invervals..
