XM2 lasted up to 115k km (6 years usage) with 2 mm residual thread depth for my Avanza.
Can XM2+ do much more than that ?

Manufacturers say 10 years or 1.6 mm residual thread depth.
Other than this is just ..opinions and bias.

which size?
btw, i went to the shop to see the xm2+ thread.can say almost same with xm2.they claim different material

Any idea if the new material is of lower (manufacturing) cost with reduced tyre life, or otherwise ?

according to the shop he told me different material.will be more grip and quieter although the thread design is the same

Thanks.
More grip and quieter would likely mean softer rubber material leading to shorter tyre life in relation to harder XM2.
At similar price levels I would give it a miss as I don't see having problem with so called XM2 noise.

How's the noise level for this tyre?

My priority is quite and comfort, and I don't drive fast, should I get this tyre?

After 70000-80000 km it is a bit noisy .

He's asking the improved version XM2+, I think yours the previous XM2?
Supposed XM2+ improved compound should be much better I guess...

Oops , yes mine is XM2 .
Someone here quoted sources saying XM2+ is said to be quieter than XM2 , so I would speculate its rubber compound is softer with shorter tyre life .
Maybe someone can enlighten us XM2+ wear index ??

Just changed to XM2+ 185/60/R15. Threadwear 420.
Initial impression it's superb quiet, much quieter than another "green eco saving" tyre.

Wow, maintaining 420 threadwear with improved noise reduction ?
That's a bonus .

Is the heavier feeling comes from the installed tyre pressure being on the lower end ?

nah, checked and adjusted tyre pressure immediately after the installation, maybe the previous EP150 was really that bald theres not much rolling resistance i'm not sure it sure as hell doesn't look that bad.

in fact i might go as far as saying FC improved

Without obtaining confirmation from you numerically , I would speculate car OEM manufacturer recommended 30/32(?) psi is being followed by the air 'pumper' .

At tyre manufacturer permitted psi of say, 36 - 40 the car steering simply can't be heavier , doesn't matter China or Michelin tyres .

Science suggests rolling resistance of brand new soft tyres increases relatively to your 'throw away' hardened tyres , everything else being equal .

Your statement in bold above is contrarian to science .

Edit: Am not trying to be argumentative ( with your statement in bold) , but to straighten up the wrong to the right .
