That test was just for touring mid range tires where it only included Primacy 4. If you include PS3/4, they would be much superior in aquaplaning resistance, especially PS3. Check various comparison tests of UHP category tires and you'll see PS4 often are in the top 5 or 3 in most tests. The other thing about Michelin PS series is how Michelin able to balance out between superior dry and wet performance with relatively excellent durability and good nvh too.

Slight corrections, ps4 is available from size 16 onwards.

But you see, eventhough PS4 didn't top any of the wet tests but it's still on average in the top half of the wet results meaning it is still performing pretty well. Furthermore you cannot just take 1 test then draw a conclusion. Need to see several others and see on average how were the results.

Well you started bashing Michelin using irrelevant examples too which were tests for Primacy 4 and PS4 which are not even available for TS size in 15'! So if you really want to go back to TS question, so what's your suggestion for TS size then?? Falken Ecorun? I suggest PS3 cuz I had used it before and I know how good it was in aquaplanning, beating all tires that I had used aside from maybe GY F1A3 and CSC5 which were not available too in 15'. Do you know if Ecorun is really better than PS3?

As for Nexen, it may beat Michelin in comfort in 1 or 2 tests but is it reliable enough? I've seen several times Nexen got bulging issues before. Does it excel in other criteria too, meaning overall well balanced performance across the board? How often a Nexen tires tops the ranking or within the top 5 in various tire tests by reputable reviewers?

I am not saying Michelin is the absolute best all the time too. To me I even think Goodyear now has better overall line up and value for money, but doesn't mean any other cheaper brands can also easily upstage Michelin in overall criteria across the board. Heck Continental and Pirelli are even often more expensive than Michelin yet often beaten too by Michelin or others.

Then if wrong usage cannot blame the tires. The only real problem I see with Michelin is the chipping issue but that's not major. Nexen I've seen several times bulging despite proper usage. The bulging can be very slight almost not noticeable by eyes but when you touch the surface or drive it, then can feel it. So far only Hankook is really good for Korean brands, I personally wouldn't use those others like Kumho or Nexen.

Agree, stay 15 and use PS3 if want Michelin.

Yes
