I just purchased a set of 2006 17" GS 10 spoke chrome rims through ebay from OEMRIMS for my 2004 GS300. I was wondering what size tires I should get 225/50-17 standard size for 2006 or 235/45-17 standard size for 2004. The original 16" tires on my car were 225/55-16.

225/55-16=25.74 outside dia. 80.82 circ.
225/50-17=25.86 outside dia. 81.20 circ.
235/45-17=25.33 outside dia. 79.52 circ.

The math says go with the 225/50-17. Does this make sense?

I could be wrong on your tire size but doesn't the 300 come with 215/60R16?

*225/55R16 V-rated tires* with 16x7.5 JJ aluminum wheels (GS 400 only)
-215/60R16 V-rated tires with 16x7.5 JJ aluminum wheels (GS 300 only)

I'll go with what you put, sorry it didn't paste very well.

But I would go 245/45R17. You would get a little more meat on the ground.

One more thing. Before you decide on what size, price them all, one might be cheaper.
