Im asking what size tire to put on my Chrome Rx330 wheels for my lowered 02 GS430. I also want a good looking LOW profile tire with the curb protector. Summer tires/not too expensive. I bought two 245/40/18 Nitto NT555s last summer for my GS4 for these wheels and they have more of the Fat look than the low profile.. Now with the drop i want to go with a low profile looking tire maybe like 235/40/18?? Any info would be greatly appreciated.. Thanks, Jay
