Iam new to pakwheels guys.i have wierd problem with my Corolla altis.its just 45k KM's done. It will be very smooth with silky smooth roads and it penetrates soo much road noise and thuds even on slightly broken roads.i keep air pressure with 30psi for all tyres. A pair of tyres are new and another are old ones will that create more road noise?...if I have to replace my tyres,which is the best for silent ride for my Corolla altis?and about cabin noise,can the interior pannels be fixed for silent interiors? I need help guys..
