Need help with 18 inch tyres and alloys

[dharmana]

I am looking for 215/45 R18 or 225/45 R18 size to upgrade the tyres on my SX4. I can't seem to find these in my city. Are these sizes available in India? Have to upgrade my rims to 18 inches as well. I am worried about the increase in unspring weight due to the bigger alloys. Can anyone suggest a good brand which makes light but strong rims? I came across some brands like Lenso, Hijoin, etc but they are all taiwan/chinese imports. They are quite affordable but what about the quality? I don't want to bet on some cheap chinese stuff to save my life when I am going at 150kmph on the highway.

Tire Calculator

this is the tyre upsize calculator this should give you the details of the appropriate other sizes if you want to check them!
do you think you will do well with that kind of harsh ride quality? rethink what you are opting for, for a moment at least.

well if you want good alloys then i suggest, you come to hyderabad, there are many shops here which can source those for you! even your choice of the brand you want!. but be prepared to face very harsh ride quality!

i suggest you get the 17" alloys with 225/50-R17 instead but at the end its entirely your choice!

there is a shop named ashoka wheels in ranigunj minister road hyderabad he is a very versatile stocker of many brands! so i think you should be able to find it here, he can source wht ever your size brand needs are!

Hi Dharmana

I honestly think 18 inchers will be overkill for the SX4. Nevertheless, we already have a member running these on his SX4 : Check this thread (MY SX4 with 18 inch rims) out.

The only size available would be 225/40/R18

[dharmana]

Stock size is 205/60 R16. But the SX4 has got such a huge wheel well gap that any wheel combination with a diameter less than the stock size will only make the gap bigger and uglier. Hence, my concern for a 215/45 R18 or 225/45 R18 tyres.

You are right autopsyche, I think the only combination we get here are 225/40 R18. But its sure gonna increase the wheel well gap more than the stock tyres.

Rider, I think that 225/50 R17 size is ok but it won't have much less rubber than the stock size and I really want low profile to make the alloys look bigger! I will definitely try out that shop in hyderabad.

Yeah, I think the ride quality will suffer but I am ready to ditch that for more bling bling! I am more concerned about the increase in weight due to the bigger rims and the inevitable drop in acceleration as a result of more unsprung weight.

Another option I am considering is to lower the car and then maybe 17 inchers will do just fine. I am sure there are some lowering springs out for the SX4 atleast in the international market but I don't want to mess up my stock shocks/struts. Problem is that replacing the springs and the shocks will be a much more expensive affair(1000$) than just changing the springs(200$). But it will improve handling and ride quality too i believe.

Is there anyone who has lowered their SX4 yet?
