Hehe.. About time for a thread about cars and motoring. Let's keep it rolling with questions and answers. Okay, my car has 15" sports rims which, I think, make it look a lot nicer than it really is. But I was wondering.. what are the pros and cons of larger rims vs. smaller ones? Yeah, my chat with Jeremy and Chai two weeks back got me thinking about it.
LOL!! Seriously... what are the pros and cons? I found 15" rims to look really nice, at least on my Proton Wira... but I think they said that 15" may be pushing it?
ok a noob here. large rims looks nice. small rim looks dull but small rims means more thick tyre so more comfortable compare to very thin tyres.
wat model is ur wira? i think 15" for wira is ok, wont be affect much on the car. having a larger rims on ur car will affect ur FC if the rims is too big for the car, and ur speed meter will affect also, ur actual speed will not b so accurate. and it also affect ur car pick up also, coz when the rims get bigger the weight also get heavier.
yup... tyres with higher sidewalls are able to absorb the bumps better than those with lower sidewalls. 15" on wiras seem to be ok to me. you'll have to live with slightly lower sidewalls and a speedo thats not accurate (not to say they were accurate to begin with anyway)
Hmm.. Affect the fuel consumption? How so? And what effect are we talking about? More fuel consumption or less? Well, I think my sports rims are made from metal alloy so it should be lighter than the standard steel wheels.
Hmm.. Won't tyre pressure affect drive comfort? I'm keeping the pressure relatively low... Hmm.. The speedometer is not accurate? So, the reading will be less.. or more??
hmmm .. thicker tyres are better for comfort.. the tyre preasure must be too low esp. if you are going on long journeys.. low preasure tyres heat up faster if i'm not mistaken usually you need to calibrate the speedometer when your tyre size is different hmm .. i think bigger tyres will show "lower" speed on the speedometer..
Changing rims should not affect the speedometer much if the tyre size remained the same. Heavier rims will affect the performance and the fuel consumption. Bigger rims normally means heavier.
3 piece it that a joke ? or do you mean by 3 spokes ? .. or whatever its called maybe adrian should go lap his rims
Hmm.. The tyre size should be the same. Looks like lots of disadvantages for larger rims. No advantages?
Generally if you maintain the diameter of your rollers, your speedometer reading shouldn't be affected. The rule of thumb is to reduce as much unsprung weight as possible to improve handling dynamics and also to reduce rolling inertia however I'm not sure about the latter. Anyway on the issue of tyre pressure, always keep to the recommended value specified by the manufacturer for effective use of your rubbers and to prolong its life but for me, it's always extra 5PSI for city driving and if outstation trips are involved, I'll reduce the air pressure by 10PSI of the recommended setting to factor in the tyre expansion from the heated air.
The advantages are lower wheel weight and less scewing of the tires when turning at high speed. Thus better high speed performance/handling on paved roads (at the cost of comfort and costlier tires). /Olle
Hmm.. I thought alloy wheels would actually be lighter than standard steel wheels? Even if they have wide rims?
