Kiario04 1st Gear February 13, 2010 Share February 13, 2010 (edited) Use this calculator ... v chun :) http://www.carbibles.com/tyre_size_calculators.html dont need to crack head, etc ... just choose ur options :) yes, 225 vs 215 with other equal, 225 is slightly "bigger" in diameter. Hence, as i tend to mention - change tyres profile if u wanna save some $$$ over coilover ... reason being, change into coilover or etc, u may also change tyres. change tyres, if dont like can change back & sell tyres ... cheaper of the two devils ...

Jchuacl Clutched February 14, 2010 Share February 14, 2010 Tyres will be heavier and hence it'll affect your pick up a little. Your speedo will slightly slower. by about 1+% . Other than that, you'll have more lateral grip. You need to ask yourself why you want to do that? The last time I did that is when the tyre that I wanted is no longer available and I used the 225/45/R17 as a stop gap solution until the newer replacement tyres arrive. My stock tire profile is 215/45/R17.. what is the effect if i upgrade to 225/45/R17? Will there be any negative consequences? Link to post Share on other sites More sharing options...

Power of Koup nothing to shout about, just looking around for grippier tires as the stock tires are nothing to shout about either. haha.. Link to post Share on other sites More sharing options...
Furrynadz 5th Gear February 15, 2010 Share February 15, 2010 225 will not necessarily grip better than 215 a wider tyre does not equate to wider contact patch a grippier 215 will still be better Link to post Share on other sites More sharing options...
Jchuacl Clutched February 15, 2010 Share February 15, 2010 There are many choices of grippy tyres under the 215/45/R17 category, you don't need to stick to just a particular model or brand. yea was jus considering Hankook RS3s but apparently only avail in 225s...hence the question.

Lucaswh 1st Gear February 16, 2010 Author Share February 16, 2010 ic..for me it's strictly for street use. anyone can recommend grippy street tires but with decent noise level? Not expecting quiet since i expect it to be grippy. but not expecting RE070 type of grip and noise. Link to post Share on other sites More sharing options...

Bluecar Neutral Newbie February 17, 2010 Share February 17, 2010 Have read many good reviews of the F1 Asym. Even for the China made ones are thumbs up. $150 for a 17" I dun think there is anything else to pick on. Link to post Share on other sites More sharing options...

JeRrRKKKK Neutral Newbie February 18, 2010 Share February 18, 2010 kia koup can't run, why bother to upgrade the tires at all? it'd make more sense to upgrade the tires on a colt or a lancer gt but upgrade on koup = serious waste of money ++ you wanna increase the width of the tires? you trying to achieve 0 - 100 in 13s is it?

Ivan0507 Neutral Newbie February 19, 2010 Share February 19, 2010 i would suggest used 225 over 215 for 17" rim. if you used 215 for 17" when hit kerb your wheel/rim will hit first,and also your car look taller if you used 225 for 17" when hit kerb your wheel will protected by the tyre rubber. so your rim will be safe.and your car look lower and nicer.

Furrynadz 5th Gear February 19, 2010 Share February 19, 2010 "look" cos the gap is less best is to fit according to rim width 7 inch width 215 7.5 inch width 225 oversize 225 on 7 inch will cause more sidewall flex as the top part of the sidewall is pulled inwards to the rim lip using 215 is fine as long as the rubber has rim protector flanges most uhp tyres do, so no issue with kerb rash Link to post Share on other sites More sharing options...
Lucaswh 1st Gear February 19, 2010 Author Share February 19, 2010 oic. looks like better stick to 215..cos Koup's rim width is 6.5. Link to post Share on other sites More sharing options...
