Tire question about my B6
 

So im looking at some Michelin tires, the Pilot XGT Z4, and for tire sizes it has P235/45ZR17/LL as a choice.
What the heck does that mean? like the extra letters and stuff.
I looked at tire sizes for my car and it shows 205/65-15, 215/55-16, and 235/45-17
Will the Michelin tires work for me?
Also what do u guys think about that brand and/or that spicific tire?

RE: Tire question about my B6
 

P - p-metric

235 - section width(in millimeters)

45 - aspect ratio of width

ZR - z rated radial tire

17 - rim size

LL - (baffled?)

and yes those tires will work
