18" and 19" petrol consumption?

[laneza]

hi all bimmers owners! On the subject of petrol consumption between this two size of wheel ( if same manufacture, spec weight etc ) is there any big difference? i'm looking to get new wheels for my e46 and fancy this type wheels ( secret :smokin but wondering either to take 18" or 19" since the petrol consumption also hike now... currently using 19" wheels...e46 look more "gorgeous+smashing" with 19"...i think 18" also nice...haizz don't know which one to choose lar...haiyaaa...

 

[paulpaul2]

actually e46 putting 18 inc its quit nice d, and cheaper tyre then 19 inc.18 inc will be more easy to take care then 19 inc since u know malaysia road condition one la..haha

cheers on ur new buy

hahaha that's why ar..but if i use 18", will go for 235/40/18 and 255/40/18...if 19" will go for 235/35/19 and 265/35/19...aiyoo im in dilemma now...

and one more thing...since many normal e46 standard wheels only 16"...so thats mean our spare wheels/tyres also 16"..if we using big wheels for example 19" or 20".
(normally shop only sell 4) ..if something problem with the tyre pancit on the way travel how lar put 16" as spare...not senget ar? is it orait ar?im still wondering now...

18 inc = front 225/40/18 n rear 255/35/18 depend on the wheel offset

regrading to ur spare tyre question i can answer u that's no problem because the smaller rim with bigger tyre, bigger rim with smaller tyre, cheers dude

so what size of tyre for this 16" spare equal to my 19" 235/35/19? maybe 60 or 70 thickness?

bro,

p/s: changing rims/tyres from stock 16" to bigger ones.......the moral of the story is if you want to PLAY then you have to PAY

 

[mafia]

yeah true.. u wan big wheels.. u pay the price

 

[bluepanther]

.....my e34 is running on 19" rims.....using 235/35/19 tyres....oledi 2 years. Never bothered to calculate the difference if using standard 15" rims (whatfor...difference to small..) Jerman is right again....u wanna play u pay.

In the Fraser's hill Drive...on the way UP....i got a flat front tyre....changed to standard 15" rim + 205/65/15 tyre....went up again and came down straight to KL. NO PROBLEM.

haha i think if 14" to 18" sure got dif because of weight...unless if we use superlight weight CSL alloy wheels..haha..but like syahruln said no noticeable maybe ur car sentiasa makan banyak minyak,...hahaha..ya lah u rite lah bro..i think 18" to 19" no dif lah..and also 17" to 18"...

already decided now may go for 19" wheels...will take all the risk..hahaha

 

[laneza]

wallawei syahruln pakai turbo charged ar? no wonder lah he said no big dif..all the time fast one..

Does it make sense that provided the density remains the same, the greater the mass of the wheel, the greater the fuel consumption?

 

[Jerman]

2cents,
From my personal experience and what I have read, weight plays an important factor in fuel consumption.
1. Try weighing the 215/55R16 tyres vs 235/45R17 and 245/40R18
2. In general, bigger rims means more metal = more weight but of course there are some quality rims which are really light which compensated the increase in rim size.

In the end of the day, it depends on what you want......gaya-mesti-mahu or "being-practical"
