[0w40X1]

My 14 s28i M Sport was getting bad about hesitating when taking off before shifting into second gear.

I thought I found solution by starting in Second Gear, but that was what one does when in slick conditions.

The real reason was that my Pirelli P7 run flat summer performance tires were 5 1/2 years old and 25k miles.

I put a set of Michelin Pilot Sport 4s in 225/40r18 and 255/35r18, and it drives like a dream now.

I'm guessing everytime I took off the rears would slip, and kick in fuel cut on traction control. Not anymore.

Notice old tires were 26 inch diameter and new ones are 25 inch diameter.

Funny thing is that my scangauge speedometer had to be set 4% higher to run the factory tires, and scanguage is at zero or no correction for the new lower profile Michelins.

I guess that reflects the fake 5% higher speedo needle. Now the true odometer will be in my scan guage not the dash.I watch scanguage not dash for info. Dash is secondary.
