Tire pressure in Yoko A drive

Subject: Tire pressure in Yoko A drive Sun Dec 04, 2011 1:23 am

Hi guys,

I recently changed my JK tires with the Yokohama A drive tires, inflate them with 30 PSI , since Yoko are softer tires does it require more PSI for better milage?

I guess, need to tinker with the tire pressure and find the right balance, could any one guide me?

Morderators: if this topic has been discussed, kinldy direct me to that thread.

Hi Siddharth,

The best place to know how much tire pressure to maintain, is from the shop where you purchased it.
I am assuming you have got your wheel balanced and aligned after fitting the new tires. The same people can tell you about the tire pressure.

Stock JK Vectra tires come with a recommendation of 29PSI.
When I changed over to BS Turanza, the same person told me to keep it at 32PSI owing to the composition of the tire.

Hope it helps.

Hey Siddharth,

I bought A-drives 3 months ago and i must admit they are the best tires i have ever had. Will tell you what i follow. In general, i put 32psi when i am alone or if there is someone with me. When there are more than 3 people, i put 34psi and it performs better. Thats good for fuel economy as well. Besides grip remains super!!!!

Hi adamkathy23,

Thanks for your reply.

Does the car not bounce after filling in 32 PSI? I am just asking never filled in 32 PSI but shall try definitely, I feel to find the right balance one needs to tinker around till one finds the best output desired. I had asked the tire shop from where I made the purchase, who informed me that 30 PSI would be the best.

Somehow I do not agree with him, To narrate today’s incidence where I had only driven about 20 km while going to a social function ( with the ac set on the second blue dot and the petrol tank fully filled in yesterday, with four ppl in the car) I was shocked to see two bars from the fuel indicator empty .

This got me thinking, was the tank fully filled in , or was it due to Yoko being softer tires it required a higher PSI than 30. I am at a loss to understand 02 bars from the fuel indicator getting empty for just 20 odd km. Must admit that there was traffic on the NH 8 highway due to some police bandobast, but still not justified.

Have you or any one experienced such a scare??

Thanks Surya,

I shall have this done right away, yes you are right Yoko being softer tires would need more pressure, but the fear of a tire burst held me back in filling 32psi.

Yes the composition play a crucial part, JK tyres are hard tyres and depending on the composition of the tyres hence required 29 PSI.

Wheel balancing was done upon the tyre change.

I have just narrated a drastic change in the fuel efficiency in my post may be this has got to do with the 30 psi that I inflated the tyres with. Have also have a post on the difference in breaking that I noticed with the Yoko tyres, suggestions and experience sharing will put one at ease.
