Here is a little comparison of Supra-L 15x6 wheels vs 1978 Celica GT alloy wheels and Celica GTS/Supra 14x7 alloy wheels.

The Supra-L wheels have some sort of paint or powder coat that makes them less glossy.

Finally, some tires mounted on the infamous Supra wheels!

Bridgestone RE71 195/50-15 I am definitely pleased with the results. These tires offer about an inch more tread than my old Pirelli P6 tires (yet have the same cross section). On these wheels there is good clearance around the fenders (no rolling of lips needed) and about 1/2 inch clearance to the strut tower. 205/50 might fit equally well (it will certainly fit, but might rub the rear fender lip on big bumps).
