Yea, thats correct. As satya had driven both the upsizes the one he has and the goldie's car!!..

satya, would be better if you can tell abt the ride quality and whateva things that need to be taken care.

Satya, since you have driven both, I think you should be able to tell us more about the ride quality. Was there too much of a difference? Will he need to be careful while going over pot-holes\speed-breakers etc? Also were his tyres Hankook Ventus? The only other tyre I have seen of this size is Toyo but it was sourced from the US.

Also, I checked the upsize using the tyre-calculator available at http://www.chris-longhurst.com/carbi...yre_bible.html and it is well within the recommended upsize in terms of overall rolling dia.


2 cars here have r14's ...even iceman's e-zen had 14 inchers ...another b-zen from mumbai which won the recent drag race beating even turbo city's has 185/55r13 ...

amitoj is using 24 psi ...and he says the ride is wokay ......i was soo excited about driving his car ...that i forgot to switch on the lights and also to close the bonnet properly ...

yeah those are hankook's...

about speed breakers ...i cannot say much ..... as teh supension has been stiffened and it has been raised in teh rear....

but i feel for eveyday use 165/60 will be more than enough ...

about pot holes ...i think he might have to be careful as i have lost 4 of my 60 profile tires due to potholes and stones..as the 195/45 tires will have about 88mm side wall while the 165/60 tires have 99mm side wall

the OE 145/80r12 has 116 mm side wall

So being in safer side by getting 165/60 would be a good thinking... rather going for some high upsizing and facing unwanted issues later on.. coz messing up with rims and tyre is not allways gud!!

Also keepin an eyes on what you said about pat holes and stones, coz leaving main roads in blore, all otha roads are in so damn freaked out condition!!

And like satya said, getting 13-14 in blore city driving is a pretty gud FE.. what was the FE that ur car was giving b4 u gone for the upsize!.

i've jus pfilled ma car with full tank, need to see how gud is ma engine on FE..

Actually, these days i am using 28 and ride quality is still quite good. In fact, it was the recent drive to Hyderabad that i realised that potholes need to be a lot bigger and wider now for me to feel them
But anyways, my car had gone in not just for a tyre upgrade but a whoolllle lotta other stuff.
So, if people are looking to just upgrade their tyres on zen, then stick to 13 inchers max.

Cheers

Amitoj, is there a criteria for changing tyre-pressure when you upsize or is it just trial and error to get the perfect ride quality and feel? Also what was the impact on mileage, better rim protection etc., when you went up from 24 to 28?

Its more of a trial and error, Santhosh... at least for me.
Mileage slightly improved but i dont watch my mileage with a magnifying glass anyways... so dont quote me on that
Pickup improves a bit and so does handling.
Lower tyre pressure was primarily for absorbing the bumps on the roads. But now that they have resurfaced Bannerghatta road to a laaarge extent, i dont need to worry about them much.
Going from 24 to 28 on my tires ideally should result in better pickup, improved FE and better handling, but a slightly harsher ride at very low speeds.
But the improvements will need to be measured to be sure... which i havent done.

hei guys .. was out for a lil while ... read through the post and i see how you guys have made ma thread active. Things all of you discussing helps me a lot too in selecting my tyre and upsize. I'll be able to do that only after 3 or 4 months once i get back to india.

hei Sush, nicely maintaned car..

why dont you tune up your car once. psycho would be the rite choice for this. Also as satya said 145 doesnt require suspension, as i run on the same in bangalore. but it's allways good to tune up coz ya know the bumps and ptholes in bangalore road.

About the heightening part.. satya what you say? ... i too wanna knw abt this..
