Changing our stock size 195/60/R15 to 195/55/R15 is a big no no. Main reason is the size difference exceeded 3% guideline of tyre diameter size difference that might cause failure to your braking system. Practically all tyre experts advise against it. But some still goes for it....if nothing happens, then all its goods but the risk of failure supposedly increased exponentially once exceeded this limit....unless they mod their braking system as well.

I assume you're satisfied with current size (for me it has the perfect balance of comfort and good non aggressive performance) on stock suspension. If yes, I would advise using back the same tyre size albeit having very limited choice in tyres. Also anything above 55 is considered non performance tyre, so my initial choice of PS3, V12, Neuton etc all can baling longkang liao. If want those good tyres....change the size....205/55/R15 will be a good bet at 1.4% difference if you want to stay on 15"...

Do note lowering the height 60 to 55 will decrease the comfort level, more bumpiness. Grip will be better due to wider tyres but more makan minyak since more road contact.

I'm leaning towards Yokohama C-Drive 2 for stock size although it has louder noise issue in its later life but wet and drive performance has no complain so far by the users. Michelin XM2 is ok but pricey tho. CC5......not so great nowadays compared with the other 2. So thats abt the only good choice you have if you stay with stock.

Actually that is not the best reason to give him on putting new tyres at back.

Have explained b4 thats its for safety reason. Front old tyres less grip, less feeling of new tyres BUT we can control thru steering if lose grip. Rear tyres if lose grip, can buang wan....unless you're an expert driver with split second drive skills response, then can recover.

Having new good grip in front will cause false "feeling" of better grip while IGNORING the fact that the old rear tyres does not have as good a grip as the front new tyres, you will tend to corner faster, run faster and end up tail will buang at times....

Do note front less grip also can buang but we can still control steering to readjust back, rear buang.....there is no control at all. So new tyres goest to rear, old tyres goes to front as recommended BY ALL reputable tyres manufacturer.
