After reaching manipal, we checked into hostel no 17 and took rest till 5.
When we went out to explore the campus, the first thing we noticed was that our car had a flat tyre.
In order to simplify things let me denote the tyres on the car as a,b (on front wheels), x,y (on back wheels) and z the spare one.
Tyres a,b were new (6 months old). Tyres x,y,z were the ones that came in with the car 8 years ago! ( did I not mention indifferently maintained car?

)
Tyre x was flat. And in the blistering rain I changed the tyres with the result now I had tyres a,b in front and z,y in the back and tyre x as spare (after a visit to the local puncturewala)
There is a method into the madness of labeling the tyres. This is to understand the saga yet to come.
Since the same route for the return trip was out of question, I invested 3 hours in a local browsing center. The options that were emerged were -
route 1 hubli - nh 63 - gadag - koppal - gangavati - sindhnoor
route 2 hubli - bijapur - nh218 - gulbarga - humnabad - nh9 - hyderabad
In one of the posts at BHP, it was mentioned that there is a 25km bad stretch near gangavati... that ruled out route no 1.
for the second route, comments were made about heavy traffic on nh9 and it was inadvisable to use the same. That was a no brainer for me. Exta kms extra traffic were welcome than lunar topography as an excuse for roads. And so route 2 it was.. nh17 - nh218 -nh9.
we started early morning from manipal after saying bye to the kid at 530 (the fact that she woke up at that time itself was remarkable) and were soon buzzing along nh17. After a short distance of travel, I noticed a strange vibration afflicting the car when the speed touched 100. Below 100, it would be quiet. I reasoned that this was probably due to the spare tyre z now in use. Maybe tyres x and y were more compatible than z and y.
I would cruise at 90 and overtake at 100. The vibration got real bad if I exceeded 100. After crossing Bhatkal, I noticed a fine sound coming from the tyres. It was as if something had got stuck in the tyre. The same sound that comes when a branch or a twig gets stuck in the tyre and gives a rhythmic fine sound (swish swish type).
I decided to investigate. It was tyre y. Closer inspection revealed that some fine steel wires were protruding from the tyre. The question now was - were the steel wires external (meaning wires lying on road getting embedded into the tyre) or internal (steel belts of radials getting exposed). I could not see any major chipping of the tread.
In order to be prudent, I pulled over at the next tyre chap and asked him for his opinion. He said the steel wires were internal (shucks!) and it happens when tyre gets old. As per his reckoning it was not a major problem. He cut the exposed wires. Checked tyre pressures (vibration was due to low tyre pressure according to him) and off we went.
The car behaved a little better. Vibration was still evident but was noticeably less. We cruised the NH17 and entered NH63 at Ankola (balegulli crossing).
The ghats were crossed and we were cruising at a comfortable speed when suddenly the fine swish swish noise became an ominous thump thump noise. I stopped the car and noticed that the tread had come off in a particular section. A portion of the tread was sticking out and hitting the tyre guards / car undercarriage causing the rhythmic thumping noise.
There was a small forest road up ahead. I pulled into that and changed the car tyre. Now I had tyres x and z in the back. Tyre y was dead (life was over) but was in the boot. The condition was precarious since a puncture would now mean that we were stranded in the forest.
Hubli was reached at 3 without cause for concern. Wife was pestering me to buy a new tyre. The tyre shop which I found had a tyre but could not fit it since there was no power for last 5 hours. Since we had 4 more daylight hours, I decided to head for Bijapur. Take a night halt there and get a new tyre.
We took a little time navigating the Hubli one ways and by the time we were on to the Bijapur road it was 4 pm. We must have proceeded about 4 kms when wife said that her intuition says not to go further. She said we will halt at Hubli. That means a long Bijapur - gulbarga - humnabad - hyderabad stretch for next day. I became grumpy but agreed.
We checked in at the same place (got the last available room). The tyre shop was also nearby and we got a new Bridgestone tyre for 3950. I asked the chap to put the new tyre on to the spare wheel.
We started next day early (0500) and hit the Bijapur road. The road was excellent, traffic was sparse and the car has going a merry 120 between villages. In villages, we had to negotiate, himalaya mountain ranges disguised as speed breakers.
10 kms after crossing Navalgund, the car noise became very ominous and I realised I had a tyre problem again. Tyre x was shredded and the last few meters were run on metal strength. Steam was fuming from the wheel.
Another tyre change meant that now I had tyres a,b in front, new tyre j and vintage tyre z on back wheels. Tyre x was dead. Bijapur was 100+ kms ahead and I did not have a spare. We were back to the same situation as yesterday. And I thanked my stars that i yielded to feminine intuition yesterday.
The car became very smooth to run and soon I was clipping 120 regularly. Our plan was to reach Bijapur by 930 have breakfast till 1030 and get another tyre when shops open at that time. However since I had increased the speed, we reached earlier. There was town bypass and before we knew it we had skipped the town and were on the way to Gulbarga (another 150 kms). A flat now would render us immobile but it was broad daylight and morning hours. So the risk was taken and we proceeded to Gulbarga at good speed.
We reached Gulbarga at 12. There was a computerized wheel balance and tyre shop on the ring road and we could locate it after mild difficulty. Another 3950 changed hands. This time I asked the new tyre to be installed at the back wheel instead of old tyre z. SO now I had new tyres a,b in front and brand new tyres j,k in the back, Tyre z was made the spare wheel.
The talkative owner said tyre life is 4 years (in shop) and 4 years (in running). Tyres x,y,z were actually 8 years old. No wonder they had their last journey.
Gulbarga - humnabad - hyderabad just flew. Instead of reaching hyderabad at 7 as estimated we reached at 4 and surprised our son.
Hyderabad to Hubli is a dream run on nh7 - humnabad - nh218 - gulbarga - bijapur - hubli. Excellent roads and sparse traffic on nh 218. traffic on nh7 is tolerable and will not dent your speed. I could see a BMW clipping 150 on that section.
