so i just got some gsr blades for my civic, and i wondered if the tire size is the same as si wheels?(like throwing off speedometer and such). they have 195/55/15 on them now, and was wondering if this was a good size. thanks

 

That'll be just fine.

 

imo the tires are too tall and fat i rather go with 195/50 i think 50 series are perfect for any 15in rim...
