Ok, if you go with these wheels, your stuck with 15s. All of their 16 and above sizes do not come in the proper offsets or bolt patterens. Also, a 15x8 wheel with -18 mm will not even be close to fitting on the front, so again, your stuck with the 15x7 -5mm wheel, which will fit fine, and be just a tad more then flush with the edge of the flare. Your only options are whether or not you go with the 15x8 wheel on the rear with -18mm offset or the -5 15x7 wheel. The only decent and readily available size in 15 inch appropriate for a supra is 225/50-15. Tons of selection available, but you look for anything else close to that (wider, skinnier, 55 profile etc) and theres nothing. There is one 245/50-15 tire available (Dunlop SP8000) but it would be a poor match to a 7 inch rim (rim isn't wide enough) and it will very likely rub on the rear if you mount it to a 15x8 -18mm offset rim. The -18 rim on the rear with a 225 tire will be perfectly flush with the flare and will not rub, and with the -5 15x7 wheel in the rear and a 225 tire it will look much better then stock but will still look like it could come out another 15mms or so. BTW, our bolt pateren is 4x4.5 in muscle car terminology :wink:
Mike, eagles are heavy, I have a full set of old eagle 15x7 5 spokes and they weigh 22 pounds each! Very noticable difference when they were on the supra.
