Well, Im using 215/55/R17... air pressure around 32 or 33 PSI. The thing is that I used both PS3 and Primacy3 on the same car. Roughly 40k on both... hence why Im wondering how on earth did some of you get double my mileage...

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.

Agree to what zeng mention. It could be your alignment issue and your tyre pressure could be on lower side,
but again it is about the feeling - IMHO, the factory recommended air pressure is the minimum, and when coast, can you feel your car wanna slow down or maintain the speed is the key; if it wanna slow down then your air pressure is low.

Secondly, do you fetch a lot of weigh in your car such as boot full of equipment, always full load and etc?
Meantime can you describe how your tyre when it is fully used? It is eating a side (the side nearer to car body or facing outside) of the tyre or as a whole?

If as a whole, still most likely air pressure / high load, if a side then you have some other problems.

If my tyres are eating one side, do you think it would last 40k?

The tyres pressure is one of the reason I guess. I disliked the bouncy feeling if I were to pump 35PSI or above, hence I lowered it for comfort and also felt better when cornering.

most of my different brand tyres last 80-100k... i change not because really botak but after so long got bored wanna try something new

secret to my long lasting tyres... smooth driving style, camber and toe alignment for highway driving, tyre selection and pressure

on pressure, different cars, tyres and sizes need different pressure for optimal contact/wear... my cars i pump them all differently based on how the tyre sits and how it wears...

if your tyre eat one side despite proper toe alignment, most likely problem is camber... if camber is also good, then you most likely have a chasis or torque drive problem...

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.

i forgot to say... don't under inflate too much... can be vey dangerous... 1-2 psi probably ok...

some random yt fyi... plenty more you can search yourself...
