I'm looking at Yokohama AVS ES100s to replace my worn RE730s. I currently have 205/50-15s; the Tokico performance kit lowered front and back 1.5", so no wheel gap.

I checked out the ES100 dimensional data, found on page 2 of
http://www.yokohamatire.com/pdf/avses100.pdf

205/50R15 has 6.5" Measuring Rim Width, with 5.5-7.5" Approved Rim Width.

225/50R15 has 7.0" Measuring Rim Width, with 6.0-8.0" Approved Rim Width.

So 225s will technically fit on the stock 15x6 wheels.

Any thoughts on going to the 225s, or should I stick with the 205s?

Thanks!
