Dear friends,

Please suggest me with options for upgrading the tyres of my HONDA BRIO S MT. Currently it runs on stock tyres which is MRF ZVT (175 / 65 R 14).

What is your preference? There are various options available in the market to suit your requirement.

Performance, comfort, longitivity and so on.

The most popular ones being discussed on this forum are Yoko, XMT and BS.

The Brio is a super hot hatch. With that kind of power on tap, I remember the rubbish MRFs giving up way before the car did.

Please get high-quality rubber in the 185/60 R14 size. Difference is a conservative 1%. It will transform your handling & dynamics.

Hi GTO,

A newbie to the team-BHP forum here and desperately looking for advice . I am planning to purchase a Brio VX (Automatic Variant) next week. Now i was thinking of upgrading the tyres and i had few queries-

1) you mentioned in your post that there will be a increase in handling and dynamics, which i guess can be atributed to the section width increase, but wont there be an impact on the fuel economy ? An issue since the Automatic version seems to have a lower FE than manual to begin with !

2) Am planning to go in for after market alloys and while i looked upon the steel tyres vs alloy debate on the net as well as on team-bhp (
http://www.team-bhp.com/forum/tyre-a...teel-rims.html), am more confused than ever. When it comes to dealing with potholes Some people say the alloys are bad for dealing with it while others say its the steel wheels which are bad. Now i plan to use the car to commute to office and about 40% of the route in on highway road conditions while 60% are your average Indian roads with the occassional bumps/potholes and , once in a blue moon, a monster pothole/bump. So what would you suggest ?

3) Will changing the tyres/rims have any sort of effect on warranty or ,heaven forbid, insurance claim in event of a car crash ?


Please feel free to move my query if this is the wrong place ! And yes i will be posting a big fat owner review once the car is with me


Thanks,
Rollingwheels26

I'm looking for replacement, as you said MRF ones are nearing death, any noiseless ones I can opt ?

While I upgrade to 185, does the tyre pressure recommendation change or stays as suggested by Honda ?

Pressure should go down.

Hi surya I too am getting a Brio AT (Red colour ! Same pinch !) in 2 days and yours is only the 2nd Brio AT i have seen on Team BHP (other than sgiitk's obviously). You had mentioned that you had changed your 'love-o-matic's' (Sorry Honda's tag line is stuck in my head ) shoes to 185/65. And i was thinking of doing the same but was wondering if the increase in sidewall height will affect handling adversely and benefit comfort vis-a-vis potholes. your views ?

No issues buddy.

Stock: MRF ZVTS (175/65 R14);

Upgrade (by Getsurya): Yokohama Earth-1(185/65 R14)

Here all I see is the contact patch has increased so the comfort felt on the move is more than stock and better handling + dynamics. I don't think it should be an issue at all.

Congratulations for the Brio AT.

Anurag you are calculating it incorrectly The 65 means 65% of contact area.

175/65 means contact is 175mm and sidewall height is 65% of 175mm or 0.65*175=113.75mm.

If you change to 185/65 the contact patch is 185mm and sidewall height is 0.65*185=120.25mm.

Approx 7mm increase in sidewall height and 14mm increase in overall diameter.

Thank you will be posting a detailed review soon as well And i realise comfort will be more but if my knowledge of physics is right, it could be wrong , the increase in sidewall width means that there is more rubber mass that could shift if the car makes a turn at a high speed . That's what my worry is about

Approx 7mm increase in sidewall height and 14mm in ijcrea

The increase in side wall width is good for comfort for sure ! But will it have a negative effect on turning at high speeds that might occur due to an evasive maneuver during an emergency ?

Sidewall height will improve ride and since you are going to 185 the grip will also improve. A 7mm increase in sidewall height will not have a negative impact on high speed turning or evasive maneuver. It's really marginal and you will probably feel the difference only on a track.

If you are still not sure you can go to 195/60-14 which helps the handling even more. There are a few members who have gone for this size on the Brio.

If one upsizes to 15 inch alloys then what will it be?

Can one use 185/65 R15?

195 ?? wont that hit fuel efficiency drastically ? Besides isnt this too drastic an upsize for this small a car (engine) ? And while it certainly has a better sidewall size than the 185/65 (117mm against 120mm) IMHO the increased width is an overkill


And as regards to MY Brio- its not meant for fast driving but rather for everyday office/highway trips ! So comfort is a definite bonus. I am strongly considering 185/65 but just want to make sure that i wont make things worse in case of an emergency as compared to the OEM 175/65 or aftermarket 185/60 tyres... Safety first !

Nope cause when you go to 15" the overall diameter will increase by 1" or 25mm. That will mess with the clearances at the front wheel.

The general idea is to keep overall diameter as close to stock as possible. So this is an approx way to do it:

14":
175/65-14 (OE size) OD =583mm
185/60-14 OD = 577mm (Gc will go down but steering will be little sharper)
185/65-14 OD = 596mm (OD goes up quite a bit but depending on car it is usually ok)
195/60-14 = 589.6mm

15"
185/55-15 OD = 584.5mm
195/55-15 OD = 595.5mm
195/50-15 OD = 576mm

Stick to stock 175/65-14 or 185/60-14. 185/65-14 won't look great on the Brio. Too tall and may touch on full lock at the front.

195 will have an impact of FE and steering will get heavier so in your case don't bother with the 195.
