Go with the A03's 255/35 and 285/30. I sent you an e-mail. These will be close, but it will be worth it. Any rubbing (which I doubt) will be fixable with an alignment and a screwdriver. Sound funny, but I will elaborate if needed (after you install the tires).

Steve,
I just ordered the exact set-up for my 98 tt project car.
The Wheels thru Dennis at Wheel Kenitics[Blitz 03's 18's best prices!] and the Tires[pole position 03's best prices for me!] thru Toyota Tire Dealers.
Now for the BIG question?????
What is the recomended alignment spec's frt and rear for this set-up??
I have the TRD spring/Strut{bilstein}/sway bar combo.
Should i just go out of my factory service manuel????
I tried the SEARCH feature but no luck.
Thanks to anyone with any info.
