Maximum Tire Grip

Recommended Posts

I have a new 987S with 19" wheels and Michelin Tires PS2. When will I start getting maximum grip? I have about 1,700 miles. Fronts are inflated to 32 and the rears are at 37 (like the good manual says!).

How much is dependent on outside air temperature too? Most of the weather I have been in has been around mid-50's. Will I get better grip in the summer temps??

Your temperature seems ideal, handling could degrade when the roads get hot. I would say you are getting maximum grip right now. Having taught motorcycle roadracing classes, I would work on driving technique as it is by far the most important thing to increasing cornering speeds. SMOOTHE = FAST

Another opinion........ from my experience (18"s and PS2s) in temperatures less than mid 50s it takes a good hard drive to get the tyres up to full grip, normal driving never seems to get enough heat into them.

The best grip seems to come over 65 degrees and I can't say I've noticed the grip reducing when the road is very hot either?

EDIT: After a bit of internet surfing the only info I can find on best operating temperatures for road tyres seem to suggest some sports rubber works best between 100 and 160 degrees F...... not air temp obviously! ;)
