Re grooving tyres

Hey guys … Ive bought a used but perfect and next to new Tip Top regroover off Ebay ( saved me £100 notes from Dingbro’s price)… cos I’m sick and tired of putting tyres into my local ATS for them to do ■■■■ all about it … when I have an axle stripped :unamused: … Anyways my 6x2 is gonna need them all done (and they are all quoted as do able) , but Ive not found consistent info about cutting depth. Ive a front Taurus 315 to be done next. I’m a fitter to trade and maintain my own rig :sunglasses: … the tyre fabric is excellent as I’ve been careful about flints and stuff so I’m happy to do the cut. Best info I can find is take out 3.5 mm once the tyre gets to the tread bar or a bit above the bar … does that seem reasonable to you guys ?

TIA … FBF

can’t give an exact depth due to the fact some tyres have more rubber left over the cords than others, I have to say even the better quality tyres don’t seem to have much left to cut these days!
what I do know is if you cut to deep the rubber that is left will pull off the cords without even trying, which then means the tyre case is scrap!
I don’t cut as many these days and I also never take a truck for test with cut tyres (the brake rollers have been known to rip down to the wire resulting in a fail)
so it might be a case of trial and error, don’t get to carried away!

I wouldnt be putting tyres that have been regrooved on the steer axle matey as that tempting fate.
Always new on the steer

If you pull max weight, don’t bother shag, total waste of time. I had to scrap half the tyres on that prem I bought after a week as although they appeared ok on first inspection, the weight ripped them akimbo showing cord. If you run light then crack on.

This ^ a billion times, X 10.

We (that is ATS on our behalf) re-cut at 3mm remaining, to a further depth of about 4mm, giving 7mm in all.

The Michy website has info on there re: patterns and recommendations.

As for your ATS depot, it can’t be Mansfield? They are our local depot and look after us very well.

As Taurus are part of the Michelin group of tyres then popping down to an ATS seems like a good idea.They SHOULD have a Taurus regrooving pattern book there somewhere which will give you an idea what pattern should and shouldn’t be cut and to what depth.

This seems to be the average position I could find. I know some of you guys dont fancy the idea, but Ive never had problems doing this with good cases. I’ve condemned my fair share of cases that aren’t up to the job, a good probing soon reveals any weaknesses. As its my own yoke … just to give you an idea, Ive run an NSF 315 throughout its life with almost no sidewall damage what so ever, whereas, when I’ve put an employed driver on such a vehicle, they manage to obliterate any manufacturers markings on the side of the case with the abuse they give it. Also … I’m of the view that you should stop ASAP if you hear any stones caught in treads, and remove them, whereas I know some previous employees just ploughed on. So I am only referring to cases that are in tip top condition.

My local ATS are actually quite good, particularly after a certain gentleman took over the reigns ,just that even when they are dead, they still don’t seem to be able do some tasks in a timescale that’s suitable

Thanks for your views anyway folks :wink:

it’s not that we dont fancy it, it’s because we know it’s dangerous, i would advise you too ask your ats depot about fitting regrooved tyres too the steer axle of your truck and i bet the answer would be dont do it.

I recut out tyres some makes are betta to cut than others, we use mainly hankook and bridgestone and both recut to 3mm no problem, I always recut them when there 3mm to 4mm on them, I find the main problem is were you fit the recut tyres, I always save recuts for midlift on units and middle axle on trailers this works well for us, sometimes we recut drive axle on units but most of time they just chunk out when you have recut them.

Both Michelin and conti drives recut well, should be able to get another 30-40,000km on a cut, but they have to be done correctly with the right pattern to make sure they give you decent grip. A quality tyre recut at 3mm up to 6mm should grip better than the original 3mm tyre.
Tractor units with 2nd steer will hold a recut no problem, some recuts on a fixed midlife will last, some will chunk off.

Don’t fit recuts to a front steer axle.

Should be able to recut a first run tyre at least 8 mm.As long as you dont cut to the wire its legal.

PLEASE DONT RUN CUTS ON THE STEER! if your unsure why your welcome to pm me and i will tell you a tale about being dragged across three lane and a fight with the central reservation !

Yep, wakes you up it does. Drivers side front disintegration, nearly going off the A40 on the drop in to Monmouth with 30 tonne on & then being stranded just after the left blind bend, waiting for the cannon up the jacksy.

Admittedly not down to a recut tyre but you don’t tempt fate on the front axle unless you’re crazy.

Wasn’t a recut, and i too think you’re asking for trouble if you do, but one of my mates had front blowout on fully loaded transporter (yes the modern unstable design where tail often wags the dog) @ approx 50mph about 3 years ago in the contraflow north of Toddington, he held it all together and stopped safely without blocking the road, well done IMO.

Watched my dad ‘stripe’ loads of tyres when I was younger, but he NEVER fitted them to a steer axle.

A few years back I was skint and my rear tyres on my car needed replacing, sneaked round my dads and ‘borrowed’ his machine and cut my car tyres, came out really good.
When I confessed to dad what I had done he went mad!! Made me go straight to the tyre shop and have 2 news ones fitted, which he paid for.
As it happens, I still owe him the money! :smiley:

re cut tyres are not legal on cars, but are ok on front steer of a truck!
never seen a problem with cleaning the tread out on the steer, the only problem is when some numpty has cut to deep! in fact in all my time I don’t think I’ve ever seen a front blow out due to a re cut tread, it’s nearly always sidewall or casing damage!
we don’t need to “fit re cuts to the front” as the tyres are already fitted, as the tyre wears down if needed the wheel is jacked up and re-cut in position, having said all that these days I don’t cut as much due to the tyre casing been worthless if it rips to the wire

this sounds right to me
