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.
