Heyya guys. Just need to ask noob question here. Is it okay to use different ratio tyres from what I'm currently using ? For example. Currently I'm on 235/45R17 but this ratio has very limited choices in the market but 225/45R17 can find lots of choices from diff makers. Is it advisable to use diff ratio then what is the default in use ?
Can still use just that not ideal. 225/45/is about 6mm thinner sidewall height than 235/45 profile which means:
1. Your actual meters (speed and distance) will be less than indicated on the dash (speedo/odometer are overstated).
2. Your ride comfort will be reduced as you will feel more of the road irregularities from less cushioning of the thinner tires.
3. Less traction as the tire is narrower by 1 cm.
4. Car height drops by 6mm and fender gaps increased by the same hence will look uglier.
On the plus side though, your FC and pick up might improve just a bit, and of course the tires should be cheaper.

How about from a 245 to 225? Is this drastic?
You'd sacrifice a lot more in traction. Still possible as long as your rims is not wider than 8.5jj but not recommended. If your rims is 9jj already then you cannot use 225 anymore but should stay with 245.
