New tires - size up!

I went into to RADIAL TIRES of SACRAMENTO this morning after researching sizes this past weekend.

Background:
THe 02 Q45 Sport came from the factory w/245/45/18 (26.5 inch diameter)on 18x7.5 alloy rims.
At 60k miles I went to a 255/45/18 (27.0" diameter)

The base of the Strut tower on the front is the limiting factor to how tall a tire can be without using 30mm spacers( BAD)


We tried a 245/50/18 and there is an 1/8 inch gap!!!

THe diameter is 27.7 inches.
The tire weighs 31lb and the current size weighs 30 lbs.

They ordered them today and will install tomorrow.
