I'm guessing you changed to S-Drives, which are known to make a ride a little more stiff but not as much as you describe it. | |

Balancing has been done. It cannot be balancing problem as it happens only at very high speeds in excess of 170. so maybe the road was not so levelled out. I have filled 30 psi when i was driving so i am guessing it would not have been more than 29 psi. The ride is very stiff. i changed my swift tyres from 165 to 185 and there was world of difference in ride quality. i am guessing the lower profile of the S drive is a problem. i have to depending on the work load as much as 35,000 km a year so... I do drive fast so i cant keeping banging my car in potholes. i need to go over them more smoothly. So I think 195 60 R15 C drive would be better. Any other choice for smooth ride with good grip. | ||

But if you do need to change, the C-Drives would be a good bet, or you can even look at Bridgestone Turanzas which are very tough tires. Again with both of these grip won't be as good as S-drives but you can cruise at relatively high speeds. | |

| ![]() Guys I visited my tyre dealer for Innova Balancing and Alignment. I drove Yoko C-drive for 45K right now and dealer says it will go 20K more :-). Now I asked this guys about Polo left pulling, as per him Apollo stock has design fault, which is curvey on exteriors which is causing left pulling. As per him he changed almost 4-5 Polo tyres to 205/50/R15 continental one and it has removed left pulling. Guys please suggest which one will be best, I just want to overcome left pulling, otherwise I am happy with stock size too. I did went to service station twice for pulling issue they tried their level best and it didn't resolve the issue. But Tyre wala suggestion put a question mark on tyre itself. So please suggest for better upgrade and does continental make sense. |

Distinguished - BHPian ![]() ![]() | ![]() Great thread- was looking to start one myself but will stay aubscribed to this instead. I plan to swap to 205/55R15s after the warranty period of 2 years- the Apollos should have completed around 30-35K km by then, I hope. Was toying with the idea of upgrading to 16 inchers, so if anyone has any first hand experience with these WITHOUT compromising on ride quality, please share. Else it'll stay 15 inches. |

195/60/15 is not a good upsize as the car will feel more "mushy" and bob a bit (feel more SUV-ish) due to the HIGHER sidewall profile. Its ok i guess if RIDE QUALITY is more important than HANDLING. The question i have is HOW DID YOU FEEL THE CAR WAS ON THE STOCK 185/60/15 TYRES? I did feel that the car bobbed a bit on undulating surfaces, nowhere near as much as the new verna, but still noticeable. I have hence booked a Polo as i feel it is a better handler and thats where the fun is for me!! | |

The car's ride quality was better when it was on stock tyre's than the S drive 205/55/15 i have now. It was wobbly on speeds in excess of 175 so maybe the road condition and that this car does not have lot of down force could be the issue, or the tyre pressure, balancing could be the issue . I remember the faster we drove cielo the more it would stick to the ground. Its not that in this case. But the ride quality is very bad in 205/55/15 in S drive. IF i go over big pot hole, the car would bang in it so hard that i am not sure if it will come out fine or not. there are many small speed bumps on the way to Goa, usually six in a row. When we drove in Optra to Goa, if in high speeds we could over em, if we could not slow down. In Vento with 205, the car rattles up its ridiculous. The cornering is amazing. But as these car are not going to be cornered every day, it is better to have a combination of both. So i think 195/60/15 would be good choice as it would be better than stock tyres in every way, comfort and handling. | |

![]() Drive safe buddy- I don't think we have any roads in India that can sustain speeds like that. | |

Yoko S Drives are the best tyres i have ever owned. I had them on my 2003 Accent and they were just brilliant. The car stuck like a leech on wet and dry well surfaced roads. Obviously any performance tyre is not going to feel great on bad roads. You cannot compare the ride of the Optra versus the Vento over speedbumps...just as both cars will feel very different around corners. I am guessing the Vento will rattle and thud just as much with stock tyres over the bumps with stock tyres! I still would say do not change to 195/60 unless you drive on unsurfaced roads everyday (like we have here in Cochin). Maybe what you should look at is a suspension upgrade! Adjustable Bilsteins for example. Then you go from comfort to sports mode at the touch of a button and not worry so much about the tyres! | |

Driving performance tyres on bad roads is not a good idea anyway. The comfort is already low with the thinner sidewalls. The jerks gets amplified by bad roads! | |

Distinguished - BHPian ![]() ![]() | ![]() Wheel upsizing is quite common and is done for a variety of reasons. But some of the reasons that people justify upsizing can be myths in reality. Most of us believe that wider tyres have a higher contact patch and hence provide better grip or stopping ability. In reality the contact patch is a factor of the weight of the car and air pressure inside the tyre only. The contact patch area is the same with a wider or narrow tyre if the weight and tyre pressure is constant. The contact patch on a wider tyre is wider and shorter, whereas on a narrower tyre it is narrower and longer. Wider tyers with shorter sidewalls aide cornering ability as the tyre flex is lower and results in more direct feedback to the driver. Infact a wider tyre is more susceptible to hydroplaning than a narrower tire as it is not as effecient in disbursing water. Wider performance tyres have better gripping compounds which generate more grip and control than standard OE tyres which our car manufactures provide. It is this quality of the tyre that improves grip and not the size per se. Going too low on the profile increases the load on the suspension as the tyre looses its cushioning ability as there is less vertical rubber to flex, and the shock is transferred more directly to the suspension. Which is why many mfrs say that you void the suspension warranty when you upsize. Of course one reality you cant argue with, is that cars really look hot with wide low pro tires. ![]() Last edited by Santoshbhat : 7th August 2011 at 18:20. |
