There are random wear bars in B, C & D channels. If you are making contact with the wear bars then they are shot. By the looks of it you only have 2 or 3/32th tread remaining. Time for some new shoes.

Agreed - time for new tires. From the wear pattern it appears you've been running too much pressure in the rear tires. Also, if you are switching to PSS on the rear then you should replace the fronts with PSS as well.

It's not a good idea to mix different types of tires on the front and rear because they'll have different grip and/or handling characteristics which will upset the balance of the car, perhaps even making it unsafe to drive in certain conditions: e.g., the wet. Also, mixing an old tire with a new, different type of tire is only going to make some of these things worse. Why not buy another set of rear tires that match the fronts? Then by the time you wear thru the 2nd set of rears you'll probably have worn out the 1st set of fronts and at that point switch to four new PSS tires.

I would not suggest mixing AD08 tires with PS2s. The two tires have drastically different characteristics and the car will not feel right.

I check AD08, and found they only have
245/35R19 89W Load Index 89 = 1279lbs (580kg) per tire Speed Rating “W” = 168mph (270kph) $262.00 (ea.) 265/35R19 94W Load Index 94 = 1477lbs (670kg) per tire Speed Rating “W” = 168mph (270kph) $297.00 (ea.) my wheel is ZCP , stock tires is 98Y , speed rating "W" is acceptable, i don't think I can drive over 270kph, but how about the load capacity? 245 only 580kg? and 265 only have 670kg? is it enought? how about if my car have 4 people on daily driving? |

You can even go wider if you wanted, with 275/35/19 in the rear. AD08s outperform stock PS2s in the dry
