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

Bro,

-If u wan upgrade, then no fuel economy
-If u wan fuel economy, then no upgrade.

Pick your poison.


Then there's : If u wan fuel economy, then no grip.

=D

What i said above being what i said,

175/65 R14 is TOO THIN for anything above 90km/h,
hence your fuel economy.

By upgrade i assume you're looking at at least 185 tyre width?

The most eco of 185/xx Rxx will not be more eco than a 175 tyre width,
so you have to decide to drop the eco and get better tyres, or just stick to the speed limit and enjoy your eco (^-^)

185/55/R15
Toyo NanoEnergy 3
Yokohama BlueEarth AE01

Based on you eco requirements, the below is good,
but dont axpect to be more eco than your current 175 width tyres:

-Michelin Energy XM2
-Toyo nanoenergy3
-Bridgestone EP150 or EP200
-Goodyear duraplus
-continental CCC6

If you follow the law of physics, it is contrary to most people believe that wider tire has more surface contact. Actually, it does not matter if the tire is wider or narrower, same car on same tire pressure will produce same contact surface area size

if only affect very little on fuel consumption (un-noticeable) then is fine..

seriously? 15" rim?

this is new... You saying that 155/70r12 tyre has the same contact patch as 245/35R18 if the pressure is the same.... I must had slept during my form 4 physics class...

I need to work the math or find article to prove it

Lol, probably did the same thing as you bro, TOTALLY dozed off! =D

Should be a little only, maybe 20 -30km less than stock

195/50/15 michelin ps3

Sarcasm aside:
1. if the new size has the SAME OR LARGER circumference, then with wider tyres, confirmed more contact patch.
2. if the new size has SMALLER circumference, then wider tyres does not necessary mean more contact patch.

But since we're talking about compatible replacements, so it would be within 2% speed (hence circumference) , hence circumference difference between any compatible size would be negligible, then hence point 1 above.

He wants eco bro

Obviously, with increased contact patch, if it's too much, your vehicle weight may NOT be enough to push it down in the event speeding through a puddle of water on the highway, and you'll aquaplane.

The golden question: How much contact patch is too much? =D

Can’t imagine bezza with 15”.. must be underpower?!

remember

grip good = noisy

grip so so = quite

grip good = expensive

grip so so = cheap

long lasting = no grip

EP200 ad discontinued. Now EP300
Dude, people ask for 14...

185 / 55 /15 make your car take corner easily and very confident. I always drive on MEX, seriously stock tyre setup wont dare take corner, as it feel want to turtle and it is more for straight line.

there are ppl change to 16", but more for stance style. Up to you la, for me 15" better hence a lot bezza owner looking for Alza rim.

15" rim need to be 36 or 38 offset with 6.5 or 7 jj. My car rim on P1 Buddy club offset 35 and 7jj. Ngam ngam not kena fender
