Well, Spent more than half a day at a tire shop and another half for alloys. here are my conclusions,
1. Rim width of i10 steel wheels is 4B -- So tires with 175/70 R13 wont fit. Due to drag, chances of tire coming out on highways -- A strict NO NO
2. For better match on i10 175/70 R13 seems right choice.
3. For added advantage like looks and reducing unsprung weight alloys are better -- Wanted to avoid though.
3. Have to go for alloys and that too of width 5.5J 13"
4. Tires -- Michelin XM1+ finalized
5. Alloys -- still hunting (Need a decent 5 spoke design -- you guys help me out)
Total cost of tires plus alloys will go upto approx 35000 INR ( All five )
