Just upgraded from my 14 Sport not too long ago. On that car I loved my Michelin Pilot Sport AS 3 plus. Always been a Michelin fan, however I've noticed that these Goodyear tires are getting some decent reviews. After 700 miles, they seem to have gotten smoother (car sat for 7 months on the lot) I plan to road force balance them in the future to make sure they ride smooth as possible. How have you SR owners liked them. I live in Pittsburgh so we do get a fair amount of snow.

 

I replaced the harsh noisy OEM goodyears and I bought Michelins Pilot Sport 4 (same than S4), but 255/40/19 instead OEM specs 245/40/19...the best upgrade for my Maxima SR...smooth ride, no noisy, better corner and curb handle, better dry/wet performance.....all these with a little additional rubber...

 

You know with the smaller diameter tire your speedo will be off a bit and you will rack a miles at a faster pace.


Tire Size Comparison
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
255/40-19 4.0in 13.5in 27.0in 84.9in 746 0.0%
245/40-19 3.9in 13.4in 26.7in 83.9in 755 -1.2%

 

You are right. But that 1.2% difference do not affect the brake system or the others safety systems. Referring to the speedometer, when show 60 mph, means 59 mph. And when the odometer reaches 10 000 mi, will be 9 883 mi.
Not big deal when you get a confortable ride, unnoisy, no harsh and jumpy ride with a little more rubber.....IMHO...
