One of my front tyre prematurely 'botak' cos of some shock absorber issue (which was rectified) Question is that will there be any problem, if I only change the two front tyres which will be of different made/brand from that of the back? The reason for not changing the back tyres cos the threads are still good for maybe another 10k km at least. My original was Continental PremiumContact while I plan to change my front ones to Michelin Pilot Preceda 2. Views?
