if the wheels fit on the gs430 with no fender mods, it should fit on 350 as well. just the tires need to be changed

Thanks guys! I went ahead and ordered 235/35/20 tires for the fronts to keep the rolling diameter close to 275/30/20 for the rear. I learned PLENTY from this thread about tire sizing and risks for not making the rites match on an AWD.

Now....if i could only understand how offsets are calculated....

here's a start. and as to how to get good offset info say for the 3gs, then it's a lot of references, calculations, experience, and trials

you'll never find 2 the exact same. tire heights are all based of percentages. the 2nd number is the percentage of the first number. ie, 245mm wide and the side wall height is 30% of 245mm's.

ok so what is the widest tire I can run on a 06 GS300 awd cause when I redid the size with a 285/25 its more spot on then the 275/25
