So is it manageable or no? What are the effects if this other than minor error in milage? (I am not interested in changing the tires again because of extra cost)

Experts please advice. I am going to replace the stock rims with alloys by next week.

Unfortunately 185/65 R14 is staggeringly off by 3.82% from stock tyre's diameter (165/80 R14). It is widely acknowledged that error percentage must not exceed 3% since it may lead to higher risk of suspension damage or even brake failure. 185/65 also brings down ground clearance by almost 12mm (half of almost 24 mm diameter difference between stock) 185/65 R15 is more within tolerance limit.

If I were you, I would, without any delay, get them replaced by 185/70 R14, the correct upsize. If you have not driven them more than 300-400 KM, the dealer should adjust their full value while exchanging them for 185/70 R14 and price difference between 65 and 70 should be so minimal as to not warrant any cost concern. Minor cost difference shouldn't be a concern when safety is at stake. In fact a sensible dealer shouldn't have given 185/65 R14 in the first place.

Thank you for the information. I have spoken to the dealer and blasted him. He is now suggesting 195/70/14 is that correct? Please reply ASAP.

Yeah, you can fit 195/70 R14. But what tyres?

Bhai, 195/65/R14 is the correct upsize and so is 185/70/R14.Anything else just negate.

I would say stick to 185/70/R14.More than enough for the swift and since you are gonna fix them on stock rims anything more than 185's cant be fixed.

Not true. 185/70 R14 is the best. then 195/70-R14 and then 195/65 R-14. 205-65-R14 is better than even 185-70-R14.

Guys thank you all for the information. I still am running the 185/65 R14 continentals. I went to the dealer and tried 185/70 JK's and 185/70 Bridgestones also tried 195/65 and 195/70 (Qualis) goodyears , the ride on either one was not as good as my current 185/65 continentals. I guess I am going to retain them and do with the 3.x % error and reduced ground clearance of 5mm. Anyways my car is hardly loaded with more than 2 people.

There were two other swifts there which were being fitted by the same tires. One of them was replacing newly installed JK's. I tried warning them but... well I say I have company lol.

@gsbhatia: I want to know how can these tires result in break failure?

If you go to the tire size calculator, and enter stock size as 165/70R14 and upsize as 185/65R14, you'll get a pop-up with the brake failure disclaimer/warning. I also don't know the physics behind it, but this and this(Plus Sizing section) have an explanation.

Default Does swift 17incher requires suspension work

OT: my friend is planning to buy a second hand Swift vxi at chennai tvs and would like to get a confirmation on the following.

The Swift has 17inch alloy wheels and one of the mechanic who went with my friend has said that this could have involved suspension adjustments and may not be a good buy.

Please clarify if the upsize needs a suspension work and what could be the potential problems with this after buying.

ps: since alloys and tyres for Swift were being discussed, thought let me post it here.

Fitting a 17" wheel on the swift does not involve any suspension work. Your friends mechanic does not know what he is talking about.

The only after effect of fitting a 17" wheel is that the ride is bumpier and the suspension goes through a little more wear & tear. That being said the wear & tear also depends on how the car was used by its previous owner.

From where I understand from article and the links given by you the pop up saying break failure is like going a little overboard. What the 2nd link says is that the Discs my heat up as there will be more revs on the disc to stop the car over the same distance/speed. The suggestion is to keep a check on the break pads and the break fluid at all time (Which I anyways do).

I can upgrade the break pads if needed (I had done that on my palio) for better breaking. As of now I have done highway runs and city runs after tyre change and have felt no difference at all in breaking.

The gurus on the site please put some light on this.

Just follow the manufacturer's specifications and you should be happy.

But there are no manufacturer specs for a swift shod with 195s
