What is the max size RIM for Saga FLX SE ?
Thinking of changing to bigger RIM for better stability

u can ask ur question here as many ppl will give u a good review of which is better..

Saga BLM Club

Since you're looking for stability, I gather you won't be looking for anything thinner than 195 width, so your options are

195/50/16
205/40/17

Bear in mind the Saga has tiny wheel wells, so the above sizes may cause you to scrub the mudguard (I changed to to 195/55/15 and I'm already scrubbing the mudguards occasionally when steering is fully turned).

The size will also affect the speedo readings and for the 205 width you may need to use spacers to avoid scrubbing the inside of the wheel well.

Not many choice for 195/50/16 & 205/40/17 tyre size..choose 205/45/16 better

id run 185/55r15

185----sufficient grip plus low fuel consumption FC
/55---- ~100mm/4in tyre wall thickness, stable but stil comfortable on our kidney torturing local roa ds
r15----- lightweight/ low FC +affordable----e.g match it w/ a light advanti storm wheels

---perfect

dont follow others, set teh standards

15" rim - Tyre size: 195/50/15 or 185/55/15
16" rim - Tyre size: 205/45/16
17" rim - Tyre size: 205/40/17

use 205/45/16 tyre on saga flx se also here, pretty good on the road

but no need to ketuk2 mudguard, i only use stock spring

by the way, it's R3 rims

What if 5 adults in the car? will the tyre hit the fender?

Can use tyre 165/65/r13 or 155/65/r13 for saga flx se?

Just use michelin pilot sport 3 with the stock size 195/50R15. You will not be disappointed.

You could I guess, but it's much better to put on 175/70/R13 since the change in diameter is much smaller compared to the two sizes you mentioned.

Changing to a bigger rim will only improve the dry handling performance, but you will compromise the wet handling performance.
