Piston Slap: Tyre Size Minus 1 or Minus 2?

Dear Sajeev:

I have a Gen 7 Toyota Camry V6 and I am getting close to replacement of the factory 225/45/18 low profile tyres. The selection of long wearing low profile all season tyres in 45 series is pretty slim. The four cylinder version of my Camry has 215/55/17 tyres on 7×17 inch rims and the selection of long wearing 55 series touring tyres is much better. My question is, since I am not really a ‘sport driving type’, would it be better for me to find a nice set of wrecking yard alloys and downgrade to the smaller rim/taller sidewall size tyres? Is the difference in performance between 45 series and 55 series noticeable or should I stay with the original low profile tyres.

Finally, Discount Tire seems to really push their ‘tire certificates’, a road hazard protection plan for $20/tyre. Is Road Hazard really necessary on a vehicle equipped with TPMS?

Cheers,

Gavin
