The tyres from the pics also look worn out to add to the fact that the M3/M4's struggle for traction. :dunnoanymore:
Actually a worn tyre (to the extent that these are) will provide better traction in the dry as there is less tread squirm. These look to still be above the wear indicators but are certainly not good for any wet weather as they are....standing water would be a huge problem.... (well....not anymore......)
I disagree. The more my tyres got worn on my M3 the more is struggled to put the traction down. Mine were near the wear markers before I replaced them and any form of exuberant throttle would have kicked in TC or lit them up if I had TC switched off.
Seems odd..... Especially when one considers the early days of Group N racing on road tyres (before the tyre boys started making special compound "standard" road tyres) because in order to get better grip and stop the tyres chunking the guys would skim the tyres down to wear indicators or slightly less.
My experience with my 320d's and Golf Gti was that the greatest dry road grip levels were experienced just before the tyres needed replacing.... Cars became very direct and predictable with the absence of squirm that new tread inevitably has...
Anyway whatever the respective experiences may be the tyres in these photos are still apparently legal with 1mm + of tread depth.
A little off topic here, but I would just like to point out the following:
Yes the guys used to skim tyres in the old days for the Stannic group N racing, and they did in fact grip better when the sipes in between the tread blocks are shallower.
But……
They used new tyres, and skimmed them, meaning that the rubber compound is still soft as it was intended right after the vulcanisation process.
A naturally worn down tyre is usually old, and the compound hardened because of age, and many many heat cycles. So even though there is less squirming of high tread blocks, the tyre has less grip overall (compared to a new tyre) because of hardening.
New tyre skimmed > New tyre > old worn tyre
PS - This only applies to dry tarmac
