Khyber - Performance after Complete Engine Overhaul

[pwuser147983858371]

Optimo is good tyre and works nicely till 40-50k kms else get sp sport 490.

Changed all four tyres of my Khyber again. I could have replaced only one tyre, the one having a big bubble but since it was the second tyre with a bubble in six months duration, I went for all four tyres replacement. I had General BG Tempo Plus tyres in my mind but on inspection, I didn't like them much. Also it was not recommended by any shopkeeper.

I checked some Dunlop tyres but they were old, manufactured in 2015. The shopkeeper recommended me to go for Taiwan made Sonar Primax tyres as according to him, hardness wise they lie between Yokohama and BG Tempo Plus. Also the container arrived a day ago and the tyres were fresh. Manufacturing date: April 2017.
Price: Rs. 19,000/- for four. Nozzles and balancing included.
I paid him Rs. 12,000/- after adjusting the old three tyres. The fourth one when opened had a big crack inside which was dangerous.

Six month old Yokos

SONAR PRIMAX

First impressions, they are not as comfortable as Yokos but I guess that is a price you have to pay when you are not selecting super soft tyres.

@hassantahir2 You have mentioned in one of your comments that you have kept these tyres, how do you rate them?

I have used these tyres about 6 year's and around 45k km without any problems and just faced 2 punctures in all these year's.
These were a bit softer than the Dunlop i have ATM also the road noise was minimal.
I wanted to get the same tyres again this time but these were not available in FSD at any tyre shop.

Yesterday got the air pressure checked from a digital meter as ride was bumpy and hard although the steering was very light. The air pressure in all tyres was 35. Brought it back to 30 and now though the steering has become a bit hard but ride is comfortable.

I guess so most of the tyre shop's have inaccurate gauge when i got new tyres according to the tyre shop person he told me that he had filled 28 psi in all four tyres but upon getting the air pressure checked it was around 40 psi in all tyres.
I am keeping the air pressure at 28 psi in all four tyres due to road conditions here.

[pwuser147983858371]

Different gauges different calibration, you get it to 30 psi and check it with other shop it can be 35-40 psi

Yes true. But the tyres feel good at the current tyre pressure and I used to check air pressure from the same gauge/shop when I was having Yokohama tyres.

The SONAR Primax SX-608 tyres have very good road grip.
During the last rain spell, I applied sudden brakes on Islamabad Expressway at 80 Kmph speed and the car didn't skid at all.
These tyres have very low noise as compared to previous Yokohama S707 tyres.

I did not face such issue after engine overhaul, although the car was consuming a lot of oil before overhaul.

[hassantahir2]

What is color of smoke?
White, blue or black.
White indicates coolant/water burning.
Blue indicates oil burning.
Black indicates extra rich air/fuel mixture.

[saboor73]

Silcener must be full of carbon build up before of oil burning before overhaul smoke will vainsh after heat cycles

[pwuser150617443122]

what is heat cycles?
my mechanic asked me that pahly jo ganda oil ta wo cyclencer main hy is wja sy smoke aata hy but after few time thhek ho jayay ga now 300 km running completed but after 300 km i face same issue

[pwuser150617443122]

Carbon jo jama huwa wa hai silencer mai wo garam hokar duha ban jata hai jitni bar garam hoga utni bar duha aae ga gari ko long trips per istamal karein sahi se garam hone dein jaldi saaf ho jai ga ya tou ap kisi silencer walo k pass ja kar yeh bhi karwa sakte hain k pressurized air k sath petrol se safai karwa lein tou ek hi bar mai yeh sab aaf ho jai ga
