"PERFECT" Tyre Upsize for Alto Vxi

[SLK]

Ok guys, Stock tyres for my Alto have lived their live, its time for a slightly better set of tyres.
The 145s are out rightly inadequate to handle even the tiny car’s 62bhp.
Here’s the complexity in this tyre upgrade…
1) No alloys >> the rims remain stock 12” or at most 13” steel from the wagonR.
2) Are a 4.5J rims good enough for 165s?
3) Does the WagonR’s rims have same PCD as Alto?

According to calculations the perfect up sizes are 155/75 R12 and then 165/70 R12.
Or
If I get the WagonR 13” rims the perfect up size is 155/65 R13.
(The 165/60 R13 is about 1cm small in diameter therefore ruled out)

After this went looking for the sizes in 12” available….
155/75 R12… NO
165/70 R12… Only KUMHO! & another funny brand

Now please suggest me
1) What brand to go for (preferable tubeless)?
2) And where in South Delhi do I get the odd sizes?

I am inclined towards 165/70 R12 & I have seen people use this size in Goodyear-tubeless … so it’s got to be available but WHERE?

I am inclined towards 165/70 R12

with stock 4J steel rims No never try those ...

What brand to go for (preferable tubeless)?

Try to avoid tubeless with steel rims....can cause problem in case of bent rims...

Are a 4.5J rims good enough for 165s?

Still working on that....

And where in South Delhi do I get the odd sizes?

Its 4.5J... and as far as I have read on the net, 165mm is the absolute maximum you can put on 4.5J.
I went to this tyre shop at Ajit Arcade (near Kailash Colony)... the guy doesn't have 165mm says put 175mm.... on 4.5J rims..... people put that on 800s its no problem. (I'm like, go to hell!)

Right .. alto's rims are not very well built anyways, but then I thought, its a 12" rim and about 11cms of rubber guarding the rims edges. What say?

Also I have tubeless on my wagonR with steel rims... although had one air blowout already ... but it was too severe an impact to be blamed on tubeless tyres.

Its 4.5J.

Are u sure????
To my knowledge the alto has 145/80-12 rubber with 12x4J rims.....

I Dont believe these tyrewallas....they suckk big time ....decide the size before going n dont take their opinion....

U never know when u gonna crash into a pothole unless u drive around India gate most of the time.....Even an impact at 60kph is enough to spoil the rim with 80 profile tyres...

Just checked!!... ITS ... 4Bx12... ***!

I had actually checked WagonR yesterday as 4.5J .. so assumed since both cars come stock with 145s.. both must be 4.5..

So basically .. rims are USELESS!!

Doesn't zen also come with same rims!

So probably it concludes this thread!... if you got to stick to stock rims .. no upsize for your Alto...

Now, I think.. I'll get the same 145/80 R12 with tube... and drive it like an 800cc Alto.

Thanks kpzen...
