So I think I have realized my mistake. I should have stuck to the OEM tyre size of 175/65 R14.

The Brio has OEM 14" 5J width alloy wheels and the 185/65 R14 Michelin XM2 tyre tends to bulge out its sidewall when installed on OEM Brio alloy rims. These are better suited for 5.5J width alloy rims.

This unusual sidewall bulge made cornering and handling at higher speeds a wee bit scary as now there was a pronounced body roll. The stock OEM 175/65 R14s didn't roll as much.

Since I also have an older gen city (with 14", 5.5J rims), I swapped the City's Yokohama tyres with my Brio's Michelins. Even though the Yokohama are the same size as the Michelins (185/65 R14) they have a stiffer sidewall as compared to the softer sidewall Michelins.

The Brio immediately handled better. Steering was more precise, that 'lofty' feeling of the Michelin tyres has gone. I haven't taken it on the highway yet, but I'm sure it'll be all good.

My tyre pressures are 29 psi front and 27 psi at the back with a single passenger (me)

That 'Thump' is probably the sidewall compressing under load. I too used to experience it but never bothered.
The Brio has soft springs upfront. The Michelins makes the ride softer. While this might work well in the city at slow speeds, highway dynamics are ruined.

I maintain a tyre pressure of 29 psi (both front and rear) in the city and bump it up to 32 psi before heading out into the highway. I haven't noticed any prominent increase in body roll on highways with this pressure.

Understood. Two questions then:

1. Does that mean the pressure on the side walls is too much then - since its bulging out more?

2. Should I maintain a higher tyre pressure - say 33 (front) and 29 (rear) - to compensate the bulge?

No not necessarily...its the tyre wall which is made softer to compress easier which in turn provides a plush ride.
I really donít think increasing tyre pressure is going to help. I tried it but the handling got affected. Lower pressure reduced the roll but might take a toll on tyre life. Letís see. What size are you running?
I still feel the earlier Yokohamas worked better on the city. For the Brio, the Michelin in stock size will make a better tyre.
The thing is we can upsize tyres but the OE Brio suspension and OE rims are not designed to offer a firm ride. Thatís how itís made!

Getting back to suspension, does anyone here know of any aftermarket struts for the City/ Brio. If so please share any details available
Thanks!

bilstien b14 made for the jazz or fit i think should do the job, considering getting a set for my brio as well.

BTW been a lurker too long, Have been running 195/60/r14 S drives on the stock wheels.
Pros
1.ride quality
2.high speed stability
3.better cornering ability and confidence
4.vastly improved braking
Cons
1.tyre bulge on the 5j wheel, causes vagueness and excessive tyre movement (lateral)
2.extremely noisy, trademark Sdrive.
3.abou 10%drop in FE
4.lower rate of acceleration

planning to upgrade to 15" lightweight forged alloys and new Amaze front suspension.

The Amaze front end strut( McPherson) should be similar/ same to the on one the Brio.

The Amaze diesel's front struts might be a better option considering it'll be stiffer than the petrol variant's front struts.

I am planning to change the Brio's front end suspension as well. Would be nice to know if the Amaze has better struts.

Hi Everyone,

Background:
My 2013 model Brio is about 28K KMS done (used very sparingly) and I've been facing the issue with reduction of air pressure consistently (about 3- 5 psi in a span of 10 days). Im believe this is due to a slight bend in the alloys in one wheel in which I'm losing 6 -8 psi per week (I had swapped the tyre in this wheel and after some rubbing / cleaning of alloy sidewalls last year this was temporarily fixed).

Query:
After more than 6 years with the car, I'm planning to pamper my car a little and want to start with the wheels.
1) In my case, please suggest if I should be going with a change in alloys (I like the current ones and if the problem with pressure loss can be fixed with tyre change alone I would be happy with it.
2) If alloy change is required, please suggest options.
3) I went through the recommendations for tyre upgrade in this thread. Looks like 185/ 65 seems to be the common consensus. Anyone who has changed it to 185/ 65, please let us know your thoughts. Any suggestions on the brand is welcome. (Consider me a noob when it comes to tyres )
4) Slightly off topic but pertaining to Brio: My car AC performance is quite weak, cooling on a hot and sunny day is not adequate/ fast and my wife complains of foul smell (although I'm not able to notice). What is the recommended work for this? I've got the AC cleaned a couple of times before this.

Thanks you all in advance.
Keep safe and drive safe.
