Not sure what jurisdiction the original poster is in but modifying tyres in the UK is frowned upon. Technically, cutting out the rubber sections is would be considered 'regrooving' which on a passenger vehicle is illegal (although not on heavy goods vehicles).

I'd assume that the insurers of a vehicle so fitted would be reluctant to pay out on a claim.

I run at 28psi back and front but I'm going to try 37 on the fronts next time out.

Thanks for the tip.

One thing to consider when upping the tire pressures is the additional pounding transmitted to your suspension and chassis. Not an issue for race cars, but could be detrimental in the long haul on our M3Ws.

Egads! -- The pounding and vibration using normal pressures are bad enough that one feels that one's internal organs are being rearranged on the fly! I'm using 27 lbs on the front and 25-28 for the rear. For me, this is a good all around setting.

Also throw in the ever other day walk about to see what bolts have loosened or have disappeared due to vibration. I go through a lot of Loktite!

Don't forget Laurens, you live in Switzerland and you have probably invalidated your insurance by doing a modification that is not approved.

Insurers normally ask if you have done any modifications and if so, does the car still comply.

Could be, but I don't think so.

But my question was;could this little change bring any positive change to the start of aquaplaning at a certain speed through a certain amount of water.

Probably it makes only a little difference but any difference without any negative side effects is a win.

For 100% sure, aquaplaning ALWAYS will happen when speed, amount of water, car weight and profile depth will be out of the the tolerance to preclude aquaplaning.

From all this tolerances, we as drivers only have influence on one thing, at that certain moment, and thats ..... SPEED.
So our brains need to check ALL the time; is this speed the correct one for the giving circumstances.

Certain moments circumstances can change so quickly (puddle) that we're too late to adjust this speed.
If the margin would have been just a bit higher ( through better water escape routes like the pictures I have posted ) it could be that we had stayed in contact with the pavement.

I have had Nokian winter tyres on two other cars with different tread patterns & found them excellent. In winter tyre tests Nokians always come out well, sometimes being top scoring. If you found them wanting then I dont query your experience.

I wish to add a little something for all of us to be aware of: We drive a three wheeler with the drive wheel planted in the middle of the lane, where all the oil, transmission fluid and coolant lands. Add even a trace of moisture and it can turn into something resembling ice. Motorcycles avoid the middle for these reasons. They stick to one side or the other. We can't.

Obvious when you think about it.
