Yes, I'd been having 115 +-K km with several pairs of XM2 (185/70R14) over the past decade or so.

Note: With a residual tread depth of 2.0 -2.5 mm 'ish vs manufacturer recommendation of 1.6 mm tread depth for tyre replacement.


Current front and rear pairs of XM2 have done 50K and 22K km respectively thus far - and is probably good to repeat history again.

That's not true!

I'd been doing 40psi (275 kpa) with XM2 all these while.

I 'followed' tyre manufacturer recommendation on tread wear indicator mark of 1.6 mm depth and 10 year old rules on tyre replacement.

Socalled tyre rot, roughened, scratches, hairline cracks, tyre noise, tyre hardening etc etc fear mongering are not the criteria of replacing tyres.

Most importantly, wheel alignment (as and when necessary or once in 2-3 years).

For good tyre life, Speed City Tyre and Trading Sdn Bhd in Post #1 of my thread

https://forum.lowyat.net/index.php?showtopi...ost&p=109816226

has proven to be good in tyre longevity in Avanza.

My hunch is Oscar should be ok in tyre life too, but yet to be proven as time will tell on my yesterday's wheel alignment by Oscar.

The headache part is locating a shop that can consistently gaodim or correcting problems like steering wheel off-centre AND/OR vehicle pulling/drifting to either side problem.

My search for such a specific shop continues........

My hunch is your wheel alignment numbers were the culprit, never mind they are all greens and within oem specs.

The devils (of undesirable shorter tyre life) are always in the details.

Imho, tyre brand, tyre air pressure and driving speed etc are not so much a 'real' problem as most or all drivers here has got it quite right.

Absolutely agree it is MINIMUM, to support the factory designed loads.

Below this MINIMUM, the 4 tyres cannot support the designed loads.

And you don't need higher than MINIMUM to support the designed loads.

But heck, the typical open market tyres of say, Load Index H88 or higher are designed and manufactured to withstand at a working pressure of MAXIMUM 350 kpa (51 psi).

Note: Some smaller tyre size has a lower MAXIMUM value of lower than 51 psi.

Hence ALL tyres can operate anywhere between MINIMUM and MAXIMUM, as far as the tyres (and its manufacturers ) are concerned though factory designed loads does NOT require it.
