i had potenza giii 205/60r13 on 6j rims in my indica,my observations are-
1.the grip is superb(sideways and straight),the wheels never locked even when the brake pedal pushed to max.
2.this is a considerable upsize so ride with these tyres was considerably better but apollo aceleres (my current pair,same size)are far far more comfortable than potenzas but have a weak grip
3.my potenzas were puncture resistant,only very few of them.
4.wore completely at 40,000kms.

Actually the tyres wobble when the speed is aprox. between 80 - 120 km/h and after that no wobbling at all .......
cant figure out why that happens ?

Check your wheel balancing. This will also tell you whether the rims are bent.

And do it at a good shop since you have 17" spinners, look for an experienced guy who is good at doing it.

I had 165/60R13 73H on 5.5J BSA alloys in my 1999 Zen . While the grip offered was mind blowing, they fouled with the rear right wheel arch. Later I found that the size of the tyres was ok but the rim width should have been restricted to 5j to avoid fouling. Learnt it the hard way. The tyres were also straining the suspension way too much when subjected to high speed cornering. The grip offered never let the car feel out of control even once.
I will always go the GIII way until I try the Yokohama's.

That's too much for a Zen without any mods & will rub in the wheelwells especially if there's load in the back. The Zen does not have much space to mount bigger tyres & best left on 155's at the most, it anyways does not need more than that if the engine is stock.

Ok guys this is the final update of Potenza's. Death of a tire this morning prompted me in writing this review, as they have reached almost end of their life and about 7-8K kms later I will be changing all 4. The fifth one is a Ducaro(Non-directional used as a spare) which has done barely 50kms, but now will be doing full time duty until the new tires come in.
First the killing blow.
Today morning, going to office I start hearing strange noises from one tyre, like tak tak tak, similar to one which you get if you burst a tyre or something.
I get out, look at all 4 and see all of them intact. Then I look again and the rear right tyre reveals a gruesome sight
There is a bolt smack in the middle tread. Hoping its just superficial I try to pull it out with a screwdriver and pliers. It comes out barely 25% or so of its length, and its anything but superficial.

Set out to change the tires, and the almost brand new ducaro comes out, ready to roll. Good thing I regularly maintain air pressure in the spare wheel too.

This bridgestone is almost a goner, and though it may get repaired, it will be used as a spare for the next 5000kms or so after which I will get a 4 tyre set.
This is the first puncture in 40,000kms, which is really nice considering the kind of roads the car's been to. Since the tyre is almost at the end of life, it does not hurt much.
And now for the review.
One world sums it up. Amazing tire. The best set I have got in any of the cars I have driven. Before you jump on me about noise issues with V tread, let me tell you the car is an indica DLS and after driving it for 75000kms I am partially deaf. Add to that Iron Maiden, and trivial things like tire noise does not bother me .
As for the tire itself, its virtues are many, and I have tested it on black ice, deep water high speed, dry tarmac, 50 degree+ temperatures, twisties in the himalayas, and have never come back disappointed.

The Grip offered is phenomenal, and even more phenomenal is the toughness.
Look at the bolt. This is what is needed to kill this tire. On the narrow highways many times I have hit rim bending craters, and have been pushed off road by buses overtaking, but these tyres took everthing in their stride. Except for ice, they work great on any kind of surface.
I am a happy customer and will probably be upgrading to the same tires. My only gripe is the directional bit, but that I worked around by using a non directional spare wheel.

Got the puncture fixed Actually there were two. you can see the small nail right next to the bolt near the sidewall. But surprisingly there was no air leak till they pulled it out. At 50rs/puncture, repair is not exactly cheap, but the tyre did not need to be taken off the rim
. Here's the bolt. If I had slightly lower profile I would have been looking at a busted rim!

Good to hear that the GIIIs have offered great traction and reliability for the 40k odd kms that you covered.

I've just covered 15.5k kms on my GIIIs and the line that runs along the shoulder tread is still intact. No punctures so far "touch wood".

Wolf was using Potenza GIII/G Grid (with wear similar to your tyres) on his Vtec during last years track meet and we were still able to put in some good lap times.

The only thing thats gonna replace the GIIIs on my car.....is a new set of GIIIs.

I was driving at around 60, so didn't see it. Moreover there was a truck in front of me. I did not touch the rim, I checked the length with the sidewall width. As soon as I hit the sound came because it was touching the road with every rotation.
This happened in the morning, and when I went to the puncture shop in the evening, the tyre still had 28psi pressure, I guess bolts are really effective tubeless puncture sealing device

Do you want to write to Limca Book of Records? Perhaps they would create an entry for the longest Bold that ever got embedded in a tyre :-)

Hey tanver, that was a huge bolt maan....I am still failing to understand how it got embedded so perfectly as perpendicular as it can be....also it has no sharp edge, hence failing to understand the physics behind that kinda bolt hiting the tyre so perfectly...

Even I couldn't understand this. I was driving, and then suddenly there was this tak tak sound and vibrations. Guess some things just happen!
