This could be little too early to form an accurate feedback. Nevertheless, thought of sharing a brief feedback of Michelin Primacy 3 ST after driving for about 200kms over the last 3 days which was covered entirely in the city. Since I had already experienced a better tyre than the OEM (JK Vectra) that were provided by Chevy with Cruze. Let me make this short review constructive by comparing it with Continental Premium Contact 2 (CPC2) which I used for 47,000kms
Steering Feel
First and Foremost feeling as I pulled away after fitting the tyre was, Woah; Steering feel has become much tighter compared to CPC2. Not sure if its because of new rubber or something else but, from what I recall never felt the same when I fitted the CPC2's. Definetly a big plus and now the steering feels nicely weighted in the hands
CPC2 : 3/5
Primacy 3 ST : 4/5
Tyre/Road Noise
These tyres are unbeilevably silent and live up to it's suffix of ST ( Silence Tuned).
I drove at a maximum speed of 110kmph (run-in period) on mostly tar surface ( thanks to the gorgeous road surface and infrastructure in Hyderabad) with windows open to check on its silence. I was thinking CPC2 are most silent tyres but, these beat them hollow. Love the quality of sound (which is none)
CPC2 : 3.5/5
Primacy 3 ST : 4/5
Ride
Ride is extremely comfortable and feels like your gliding on feathers laid out on road. Iam being careful over potholes which in any case are rare on Hyderabad roads and there's no jarring noise when i go over them.
I would rate these tyres equivalent to CPC2 with regards to ride comfort. 3 ST may infact prove to be better than CPC2 but, it's too early to comment.
CPC2 : 4/5
Primacy 3 ST : 4/5
Handling
I tired the corners that I do everyday when I drive about 50+ kms to work daily and they stuck to road like a leech. Phenomenal grip and much superior than the CPC2 in this department for sure. I normally take some corners at 80kmph but, tried the same with 100kmph and there was no drama whatsoever, felt safe and car stuck to its line like a well mannered baby.
CPC2 : 3.5/5
Primacy 3 ST : 4/5
Grip (Wet)
Believe you me, it's still raining pretty hard in Hyderabad and even yesterday there were thundershowers the whole night. I drove for more than 70kms in rains and the grip is pretty decent but, CPC2's was a different animal in wet conditions. CPC2 used to feel like your driving on dry conditions even in rains, they were that good. But, again it's too early to comment, so i will wait some more before forming a firm opinion
CPC2 : 4/5
Primacy 3 ST : 3/5
Grip (Dry)
There is nothing to complain about grip in dry conditions. Tyres feel soft, extremely comfortable and grip quite hard on surface.
I never used a sports tyre like S-drive, Advan, PS3 etc so I cannot really compare the grippy attitude of this tyre with them but, even for a reasonable enthusiastic driver like me, Iam more than happy with the grip these tyres provide and make a world of difference from the inferior quality tyres which OEM tyres of Cruze.
In this department, Iam not sure which tyre was better, need some more kms under my belt to come to an opinion
CPC2 : 4/5
Primacy 3 ST : 4/5
FE
Would be extremely premature to comment about anything like fuel efficiency but, Iam slightly taken aback with some initial instances as you can see from the picture below, WA seemed to have crossed the 200kms barried at 1/4th tank full.
Needle is at 1/4th i have covered 237kms ( previously it always used to be around 200kms, give or take a few kms and then needle starts slowly dropping down). I normally get 600kms to tankful with about 50L-52L of diesel coming in at auto-cut, giving out an average of 11.5kmpl to 12kmpl and the trip meter always goes back to ZERO
Summarization : Overall, iam extremely happy with my decision of going in with Michelin, a brand that iam not new to as I have used their XM2 in my previous car and enjoyed that experience as well quite a bit.
One strange thing that I note now is car feels little heavier than before and seems to have lost a bit of accelaration, you know the ability to take off seems to have come down a bit. Iam not sure whether it's due to my overall gentler handling of the car due to run-in period of tyres or these tyres have indeed made that difference.
