I should consider the tyre upgradation only when it will be needed, means after 50000 kms or 5 years, whichever is earlier. No? By the time, warranty period will also be over.
Absolutely... As Surya said, the tyres are fitted after a astute calculations of the car dynamics, weight, shape, cg etc .. SO what you have got is best for your car. When the existing ines wear out, you can go for new ones.
After your valuable suggestion, I made up my mind not to go for tyre upgrade, as yesterday I checked up FE, it gave me 15 kmpl for mix of city & highway driving (with full tank to tank basis) before second servicing. So, why to spoil this FE?
Broader tyres really looks "S$%^" on roads
People who care more about looks then FE Change of tyres is must ...
about 20 cm can be managed without an issue, unless the stock tyre is already at it's limit of girth allowable by the stock rim.
Well, Himanshu, you caught me there. I cannot go back and edit it now!
Yes, with 20 CM extra, it will be looking like a lorry - double tyres all along!
I meant 20 mm. going by that logic 155 mm can accommodate 175 max, assuming the original rim choice was gracious to allow it. Some penny pincher mfr can put a rim that accepts the OEM tyre as maximum width, and you are forced to go with rims update even for routine tyre upgrades, without rim dia change.
according to me, you should upgrade the tyres the very first day you buy your car.
all the tyre dealers in the city and also beat owners complain that beat tyres are too narrow..155 width is too less for that design..that is actually very true..same with the swift...165 is too less for the swift.
if you upgrade carefully with proper advise, there should be no dip in FE. have you already brought the beat??
Sorry I was away on vacatiion. Yes, I have already bought Beat LS on 04-03-10 and already driven approx 4000 kms. And also, I never felt any discomfort because of narrow tyre (may be, because generally I drive the Car at 60-70 kmph, except on some occasion when I touched 80-90 kmph on 4-Lane empty road).
Now, still you advise me for tyre upgradation (keeping in mind my driving habits)?
Neela, carry on with the present tyre setup, you will be fine!
if you dont want to upgrade to alloys, if your not so seen for giving a sporty look to your small car, if you drive around 60km speed always, its not required to upgrade inyour case then...
you can live with these tyres until u clock 40k on the meter ...
I hav booked a Chevrolet Beat Petrol LT i find the 155/70 R14 tyres to be smaller if i change to 175/70 R14 how will it effect the overall performance of the car - in terms of drive , control , braking , fuel consumption pls reply urgent as i would like to get them changed before taking the delivery
Welcome to CarWale Qaid! To start with, check with your dealer if the tyre upsize will affect the warranty. If so, it is better to stick with these tyres during the warranty period. When we come to tyre upsizing, you should not fit 175/70 R14 because its circumference much more than the original tyres. To keep the difference less you should go for 175/65 R14. LT model has 14 x 4.5J steel rims. Rim width of 4.5 is not enough for the broader tyre. You should go for 5" or 5.5" rims. You can also consider 165/65 R14 if that is enough. To give you an idea, 165mm width is used on low end swift models(all except Zxi & Zdi). 175mm width tyres are used in Honda City, Brio etc. When you go for broader tyres, handling will improve which is important for high speed driving, say above 100Kmph. Mileage may reduce by 1 or 2Kmpl. If you go for alloy wheels which are lighter than steel, mileage may even remain the same. Your dealer may not do this for you. It is best for you to get it done from a tyre shop. They will give a good price for the existing tyres if they are driven very less.
thx Sriram for ur valuable info on 4.5j rim
cud u pls tell me how much broader will 165/65 R 14 be than 155/70 ? and will thr be any height difference
The width is in mm, so 165 tyre will be 10mm broader. You can get a feel only if you see some cars with those tyres. That's why I have mentioned the car brands. To understand the tyre size designation you can go through this link. The new tyre is less by 8mm in circumference and 1mm in radius which is very marginal. For tyre size calculation I use one of the 2 calculators mentioned below. You can use them to compare tyres.
thx sri ram for ur response
u seem to own a swift which shows on ur profile
i chose Beat coz i got a very good discount and swift Vxi wud hav cost me 80K more just with the music system without rear wipers n defogger n 60:40 seats , reverse parking sensor n most of the good accessories
so i found Beat excellent VFM
in test drive i found the swift engine gav me about 5-10% more powerful feel over Beat , Beat was quite enough for my use
Still i wud luv to know whts the On-road performance difference between swift n Beat in ur opinion regarding the engine, drive, control n FE ? i hav read the figures but i want to know real world difference
I haven't tried the Beat, but I used to have a Zen before Swift and this much more comfortable from that. Bigger seats(good for tall people), more leg room, better handling, higher speed etc. But these are not the reason why I chose to buy a Swift. I liked everything about my Zen till the time it started breaking down every now and then. I wanted to buy a new Zen, but that model was stopped and only Zen Estilo was available. I couldn't agree to call that as Zen. They were cheating . I looked at WagonR, but didn't want a 4 seater. Looked at Alto, but the power was lesser than Zen. Finally stretched my budget and bought Swift. It is good both for the highway and city. In the first few years of ownership I took it out a lot on highways and it was very enjoyable. It is a Zxi. A great engine with good pickup, good control even at 100+Kmph and decent FE which is great on the highway and ok in the city.
It would be great to know your feed back after trying Beat, I own one and feel that it handles similar to Swift and has similar fun sporty drive feel. I was cruising around 80Kmph and felt very good hold on beat, will try at 100+kmph and checlk how it holds on stock tires. Having used swift you could clearly make out the difference and update any new buyer. I remember reading that Swift LXI and VXI have very poor brakes, It was a very wise decision to have bought the ZXI.
Even I owned a beat recently and my thoughts are similar to yours. Agree Swift is a fabulous car but at almost Sedan price. Beat almost touches Swift engine with a great VFM price. Also one more fact is that if 155mm tire is considered under tyre for beat than 165mm is under tyred for Swift(keeping in mind its wider than beat). Not to forget 205 litre boot to that of 170 ltr boot(not much difference huh).
