Go here and calculate. When changing sizes, its best to keep within the 3% rule, esp if the new diamater is larger. If its smaller, more than 3% may still be acceptable.

In your case, its larger than 3%, hence, not adviceable.

Depends on what your priorities are

Performance or Comfort.

If you want performance at a Budget, Hankook V12 is a good buy. After that its Goodyear GD5 and if you have the budget Michelin PS3

Comfort are tyres like Goodyear NCT5, Conti Comfort Contact 5, Michelin XM2
