I have recentl bought a second hand WagonR Vxi car 2007 model. Two months back when I bought this car it was perfect. In december its service was due. Before servicin two front tyres were new. In servicing I changed two rear tyres also. By mistake car was having wrong configuration front tyre and so looking at that I also changed the same wrong configuration. I saw in autocar book that wagonR vxi car should have tyres 155/65 71rt whereas my car has now all four tyres 145/70
71rt. Now the problem I feel is that in plane hihgway car runs smoothly but after running few kilometers on highway when I drive on rough ro ad steering makes a rough noise which seems to be related with tyres, wheel alignment etc. I feel that now steering or front tyre will simply be broken out. This problem started only after the servicing. What should I do, please answer.
