Default Swift tire pressure and fixing spare alloy wheel doubt

Hi,

I upgraded my Swift LDi tires to Michelin XM1+ Energy 185/70/R14 mated with Lenso 14" alloy rims. I have a couple of questions connected to this upgrade:

1. What should be the cold tire pressure that I need to maintain for the upsized tires. Tire shop person told me to maintain 30 psi for all the wheels - is this correct or should I keep a few psi extra for the front tires (I think the suggested tire pressure for OE tires is different for front and rear, front being 3 psi higher)

2. Though the spare alloy wheel fits in the spare wheel well in terms of size, I am not able to use the OE screw to fit the spare alloy wheel to the well. When I asked the tire shop person, he said that it should not be a problem to leave the alloy wheel tire in the spare wheel well without screwing it. He also said that I need to go to a lathe to get the screwing mechanism machined for the alloy wheel, if I am very particular to fix the tire to the well. Please advice.

Regards,
SKB.

1. Play around with 30-34 for front and 30-32 for rear, whichever settings you like keep it. Ride around for 1 or 2 days atleast once you change the air pressure.

2. Heard that Accent spare wheel bolt works, its just a hear say and i havent tried.

OR

Take it to a lathe/weld shop and increase the length of the existing nut with a bit in between

Jaggu,

Currently I am using 30 psi for all wheels and find it pretty comfy. But I just want to make sure that I am not creating any issue to the car/suspension with 30 psi all around (especially in front)

Regards,
SKB.

How much did you pay for those Michelin XM1+ Energy 185/70/R14 mated with Lenso 14" alloy rims.
And where did you buy them from

How do i put it, hmm

Even if you run with 28 psi all around, there wouldnt be any major damages to suspension, during normal running maybe a lil more wear, worst case scenario, but nothing like suspension worn out in 20 k kms and all.

Air pressure i would decide, is to take care of my needs of ride quality, tyre wear and FE.

In diesel swift its better to keep higher pressure (2 psi more) on front to take care of the heavier engine and the stiffer suspension upfront.

I got them from Sai Iyengar (CMH Road) and paid a total of 31300 for 5 numbers (Tire+alloy) in exchange for the Swift LDi OE tires. He took the OE JK tires for Rs.1000 each. Quoted full price of Michilin Rs.3450/tire.

Jaggu,

Thanks for the hint. So, I am going to keep 32 psi for front and 30 psi for rear - cold pressure.

i have a Ldi too i used to keep all the 4 tyre pressures at 30 and guess what my FE was only 14kpl with the most sedate driving, so changed it to 33 all tyres now and now its like i have done 200kms and the fuel meter shows quarter tank just need to wait till i finish the tank to note the FE.

by the way i have 195/60-R15 specs tyre and league alloy!

Recommended tyre pressure for DDis with 165/80-14 tyres is 33psi(front) and 36psi (rear).

If u are asking for the Baleno then i would suggest 30psi on all four.
You can definitely try and play around with +/- 2 psi depending upon the ride quality and load.

But when I took the delivery of the car, the person at the Maruti Dealer (who demonstrates the car before delivery) suggested to keep 30-31 psi for all the tires (read OE tires). When I asked him about the company suggested 36/33 combo, he told me that those values are when the car is loaded with 4 or more persons.
