I want to switch to a squared setup for both Summer and Winter - I don't track this car and I live in the city in the Midwest. After the P Zeros wear out I'll switch to something more economical, but here's my plan until then and it should set me up to save money on tires in the long run. I just need to know, does it work?

Summer Setup
Front: 19x9.5 - Pirelli P275/40ZR19 P Zero - 5mm spacer
Back: 19x9.5 - Pirelli P275/40ZR19 P Zero - no spacer

Winter Setup
Front: 19x9 - BRIDGESTONE BLIZZAK LM-32 P245/40R19 98V XL - No spacer
Back: 19x9 - BRIDGESTONE BLIZZAK LM-32 P245/40R19 98V XL - No spacer

Is a 5mm spacer enough clearance? I've seen conflicting reports on multiple forums.

10mm spacers

Regardless of spacer size, do I need new studs? I don't know anything about studs, so if I need them are there that are good out of the box?

Another forum member started talking about knurling and lost me'

The knurl is the part of the stud that goes through the hub. It has sharp grooves to keep from spinning when tightening the lug nuts.
