Yes..nowadays 99.9 % of the lousy tyreshop out there just wana con us to buy the tyres, and never bother about other factors. Will u consider other tires rather than the 2 types of tires that u stated above? Primacy "LC" = Luxury and Comfort, claimed by the manufacturer. As mentioned by VR2turbo earlier, they are more towards quiet & comfort range. No doubt, the tires are very quiet, however the wear off rate/lifespan and the grip for Primacy LC is completely a nightmare. It sounds more like the tire manufacturer has sacrifice safety for their fuel saving technology. Even the cheaper /entry level of Michelin XM1 215/60 R16 is simply tougher than a lot better Primacy LC. Put it side by side without it mounting on wheels and compare, you will notice Primacy LC:
1) it's Very light
2) width of the tire is slightly smaller compare to others same size tires
3) even the sidewall is softer than most of the tires.
(Maybe that is when the fuel efficiency came in? lol :stupid:)
That is why, maybe it's best if u can talk to someone from the tire industry who is Really close to u or ur friend about the statement i've made. Ask them to touch their heart and tell u the truth. Sometimes only the branding itself is strong..but not all products are the BEST mahh...
