What is your rim spec?

Only 1 Model/Brand for this size? (175/60R15)

currently using Assurance triplemax 185/55/15 with et38, 6.5jj rim

i saw comment from youtube car review channel

FL ori 15' rim size is 5JJ, only can fit 175/60/15, but this tire rare found in the market and the price higher than 185

but still need more info about this rim 

after weeks of driving on new rim/tyre 195/55/15, yes - it does rub the rear fender when fetch 2 big sizer, or 3 medium sizer at the rear seats. however, if solo hardly will rub; unless go thru very uneven or wavy road with certain speed (i assume like 70-80kmh).

however, it is very nice ride with this profile.. very steady and comfortable.. fuel consumption very slightly increase with same driving pattern.

Hi Sifu, rub the rear fender because of the tyre size? Can i use tyre 185/55/15 for ET38 15 6.5J? Will it rub the rear fender as well using narrower tyres?
Thanks.

Min 185, for what car? The offset seems ok. Stock spring/absorbers?

185/55/R15 with 15 x 6.5JJ + ET38 > this would be PERFECT setup

Thats right. The next best size will be 195/50R15.

Original stock tyre = 175/65/R14 (14 x5J ET45)

What you guys recommended for upgrade but still maintaining the fuel efficiency. Any opinion please?

Based on few review and experience collected from various posts, it can be concluded that:

195/50/R15 with 15 x 6.5JJ + ET35
195/55/R15 with 15 x 6.5JJ + ET38 > will rub fender when overload at rear
185/55/R15 with 15 x 6.5JJ + ET38 > this would be perfect setup

Spec: 15 inch 6 JJ
PCD: 4/100
ET: 50

6JJ - The best is still use back 185 size.
You want better performance in term of what? If want better in cornering or high speed search for UHP/Performance tires, if comfort search for touring tires. There are tires which is same size but different design/material for different purpose. If normal ride without much modification, you only see more negatives if change to bigger wider tires.

Thanks for the info. I will get 185 tyres then. Should I get 185 55 or 185 50? Any recommendation on tyres? Saw ppl recommending Dunlop D06. Thanks.

Just use back original size if everything is original. If not mistaken yours original should be using 185 55 R15

Dunlop D06 is consider as local budget tires, I did not got good experience for Dunlop budget tires.
For me would better to top up a bit go up to at least Falken or direct up to premium level like Michelin, Goodyear or Bridgestone.
