Ok let me get this straight

I have an RS with 14" wheels.<BR>-I just bought 15" wheels from a GS.<BR>-I need new tires for next summer.<BR>-My stock tire size is 185/65/14.<BR>-14" = 355,6mm<BR>-15" = 381mm<BR>-so the total diameter is:<BR> 355,6mm + 2*(0,65*185mm)=596,1mm<BR>-Now I have to get tire that will be the closest diameter from that right?<BR>-If I get 205/55/15<BR> 381mm + 2*(0,55*205mm)=606,5mm<BR>-If I get 205/50/15<BR> 381mm + 2*(0,50*205mm)=586mm<BR>-According to this, I should get 205/50/15 because 586mm is closer to 596,1mm than 606,5mm right.<BR>-I know the stock size for GS is 205/55/15, can somebody explain me all this?<BR>

yeah, you got it...just remember that certain tires run a bit larger/smaller...<P>kinda like shoes...each company is slightly different.

I'm not going to work the math but why don't you try bumping it up to 215
