Dear Indian_Mustang: Bharuch is a difficult place to look out for Alto rims. You will have to go till Vadodara which is barely an hour away from you place. You will get the rims here (may have to put an advance order on phone):
15, Sun Enclave,
Opp Jalaram Mandir
Alternatively, you can also order the rims online at http://www.mgp.co.in
All the best.
