Hey guys, can anyone tell me what would the advantages and disadvantages of changing from stock 175/65/R14 to 195/55/R15 on a Myvi 1.5?

Planning to get Advanti Storm S1 series rims.

The only thing kinda holding me back is worrying whether the car would feel too heavy after changing.

Thanks for your input

May I know whether it's obviously heavier to get your car to start moving in traffic jam situations?

I daily drive it so I'm often stuck in traffic during rush hour.

My main reasons for wanting to increase to 15" rims are for overall stability and a bit of looks.

In your opinion, the benefits far outweigh the disadvantages?

Benefits: stability, grip, looks

Disadvantages: acceleration, braking, comfort, fuel consumption

Rims are kind of the 'last' mod that I will do to my car. Already did:

Full braking system (steel-braided hose, slotted rotors, performance pads)
Stage 1 UR bars
Full exhaust system mod (extractor, piping, bullet, muffler, tip)
Low-resistance cables
Voltage stabilizer
Stiff rings (front and back)

Planning to put Michelin XM2 on the 15" rims if I'm getting them. Either that or PS3, since the difference is only RM10 per donut.

Currently already using XM2 on my stock 14" rims.

Suspension is definitely in my list but I'll wait until my OEM shocks start to die first.

Even with 195/55/R15 tyres, it won't feel apparent?

The extra contact surface and rolling resistance is kinda offset by the lightweight rims right?

Thanks bro. Now I'm really tempted to change my rims already.

Final decision is just choosing between XM2 or PS3 only. Difference is only RM10 per donut. XM2 is really quiet and lasts super long while providing adequate grip for my type of driving. Tried PS3 in my friend's swift and found it to be really noisy, and probably wears out faster too since it's a performance tyre.

Just a 2012 Myvi 1.5 SE.

Nah, just listed the mods down as I could remember them.

Yup, already went for it. Advanti Storm S1 + Michelin PS3 195/55/R15

Loving them so far despite the sacrifice in comfort.

Yeah actually pretty good. Looks awesome too. I haven't tried the grip properly yet, but I tried it in rainy conditions and it's really really good compared to stock 14" 175 tyres. The steering is heavier now and the road noise is pretty loud compared to my previous XM2. Need to get used to that also.

It was about RM580 nett for me, including installation and GST.

Front set is about RM300, rear set about RM200, then installation around RM50.

Totally worth it IMO. I had a lot of doubts but decided to YOLO and try it anyways.
