Sir, how much psi should i have while city driving?

While on Delhi - Manali trip i had 32 psi & the handling was awesome!!
Could easily throw my car on those curves!

[kpzen]

30 psi is recommended but u can try 28psi and 32psi and check out which gives optimum combo of ride comfort and handling. In my zen i maintain 29psi on all four tires.

I feel 32 psi is on the higher side. The ride becomes bouncy.

I have finally changed my car tyres. Went looking for the Turanza's and fitted Michelin XM1 - 145/80 R12. So far the performance has been good (a week now). Less road noise and very little discomfort. Can I continue to maintain a tyre pressure of 28 Psi or should it still be 24 for tubeless ones?

[rohan_fonseca]

Isn't the reccommended pressure for 145/80/r12 24psi? Does it have to be increased for tubeless?

Increase pressure when the load is heavy or you intend to drive very fast on smooth concrete.

[kpzen]

Maintain 24psi for city driving.

Hi Amtak,

Even i am planning to change tires of my Zen Vxi, How much did you paid for Michelin XM1 - 145/80 R12 ? from where you got it changed, even I stays in Borivali ? I am planning to change front two tires ( rear tires seems are in good condition ), will you recommend to go for tubeless tires ? Out of Curiosity wanted to know if Tubeless tires are also going to get puncture why shd I buy them ?

[kpzen]

145/80-12 Michelin XM1 should cost u around 1900 per tyre.

[nicejits]

How about putting new tueless tires on front with Stock Rim and stock Tubeed tires in rear ?

Completed 10000 Km running on Michelin155/65/R13 since Oct'07.
No problem so far, fully satisfied, specially on highways! 120-130 kmph seems like driving at 80kmph.
Many thanks to Kpzen, got the right combo with Esteem rims.

Hello Frenz, great thread for Zen Owner. Excellent and in dept replies from all, thankyou. But is still have some doubts of my own as i'm looking to change my car tyres too.

I am from Bangy and travel around 45 Kms everyday to work from CV Raman Nagar to EC (Please ignore if the details are not reqd) through Hosur Rd and Outer Ring Rd (Both highways and stretch around 16-18kms out of the 45kms). With that in mind my questions are:

1. Can afford alloys and wanted better grip,comfort without affecting FE too much. So thinking for getting Stock Esteem Rims. I wanted to know if it is possible to get used esteem rims ? if yes from where in Bangy?

2. Whats the best tyre size to go for without changing anything in the suspension etc along with the above points?

3. Where is the best area to find good deals in Bangy from your personal experience?

Thanks for your expert comments.

@Mods: Please make this thread a Sticky for Zen Owners

So, i will give my experience with all of them
Description 145/80R12 155/70R12 155/65R13

Km run 53000 29000 1800

Rim size 4j 4j 4.5j

Initial torque normal excellent 5% below normal

Top speed 125km/hr 145km/hr 135km/hr
(incl. odo error)

Handling poor good excellent

Ride good almost good marginally below average

Braking ability average good V.good

FE (Km/ltr) 17.5 16.5 15.5

From the above post, it seems 155/70R12 is a good option (better top speed, braking, torque etc and negligible hit on FE and ride quality)

I used 155/70R12 for about 29000km.
Had to spend on the suspension, strut dampers & now i'll be changing the wheel bearings too as i do not want to ruin michelins.

From this post, it seems i should stay away from it.

I have a Zen LX 2003 (stock tyres/rims, 145/80 R12). Now a days, when i drive, there is a pull to the left and the mechanic has adviced me to change the tyres.

My driving is mostly in the city. Top speed is not imp for me coz i hardly cross 80 km/hr. FE, ride quality, braking, pick up are imp.

1. Should i stick to 145/80 R12 or try 155/70 R12 ??

2. Should i go for BridgeStone Turanza ER60 or the Michelin XM1? I would prefer Michelin (coz of the good reviews here).

On the Michelin website, I dont see XM1 for 145/80 R12. Is it available?

TIA

Replaced 5 yr old JK tyres today. Got 4 Michelin XM1+. Thanks to kpzen for his expert advice.

First impressions:

The car is Zen LX, so no power steering. Thats was the only thing missing for me in the car. After installing the Michelin's, the steering has become sooo smooth, its unbelievable! I absolutely feels like PS

The pull to the left has stopped about 90%. I also happen to drive a swift often, which goes absolutely straight. The Zen is still not 100% steady, now it sometimes goes to left/right if i let go the steering wheel. It very minute, but still noticeable.

The guy who replaced my tyres told me to get the steering wheel bush replaced, that might solve the problem completely.

Nways, the tyres cost me Rs. 2000/- per piece. Got Rs. 600/- off for my rear tyres.

Here are some pics of the installation ...
