Will there be any negative consequences? your tyres become wider . by 1 cm only, and the overall diameter increase. the only consequences i can think of is, when u corner, u might bruse against your fencers, when u fully turn your front wheel, u might hit the inside. when u carry max load, the tyres might hit also, due to clearance is smaller. but if u can give more details like, what car?? and u got change coilover?, we can have more discussion .

I thought it will oni be wider at the side view? by the way, am driving the Kia Koup and the suspension is stock, think about 3 fingers spacing between tyre and fender.

Abit off topic but if you are really changing your tires, can you sell me your old tires? Willing to take over at the same price that the shop offers to take in.

The diameter does not increase point to point as you correctly said. It will be wider . so there will be more contact on road. more grip , more stability, higher consumption. beregond is talking about the space allowance (interior of fender) when you turn the steering. not about the height between tyre and fender.

Beregond Supersonic February 11, 2010 Share February 11, 2010 215.45.17 and 225.45.17. the (45) means 45% of 215, and 45% of 225 ( can any pro tell me if i am wrong thanks ) 45% of 215/225 is the thickness or the profile of the tyres so a 215.45.17 tyres will have a profile of 96.75 thickness rubber . and 225.45.17 = 101.25 thickness rubber. so thats y a 225.45.17 tyres is bigger in diameter then a 215,45,17 tyres . ( not counting in its wider also ) ( pls correct me if i am wrong ) lol Link to post Share on other sites More sharing options...
Billcoke 2nd Gear February 11, 2010 Share February 11, 2010 (edited) 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? More fuel consumption. Imagine a racer bicycle with thin profile tyre and a mountain bike with wide tyre, which is more difficult to peddal? Benefit? better grip, especially if your car is RWD. If your car is FWD, then you will feel that your steering is slightly heavier. Edited February 11, 2010 by Billcoke Link to post Share on other sites More sharing options...

Throttle2 Supersonic February 11, 2010 Share February 11, 2010 I stand corrected. however, the distance between the tyre and the fender edge is usually not the problem as there is usually at least 3 fingers allowance for stock. the problem is the width as beregond rightfully mentioned, that may rub the insides when turning Link to post Share on other sites More sharing options...
Eugn86 3rd Gear February 12, 2010 Share February 12, 2010 Only negative consequences i can think of is higher fuel consumption, heavier steering and less feedback from steering wheel. Don't need to worry about rubbing against fenders etc... it won't. So much space and allowance there for stock. Even if you lower the car, no problem.

Woonyang Clutched February 13, 2010 Share February 13, 2010 given the power of the koup, or perhaps the lack of it.. upsizing your rims might cause acceleration to suffer, if you remain stock. ↡ Advertisement Link to post Share on other sites More sharing options...
