Got a set of 17x7 IS300 wheels and am trying to decide on tires for 1993 SC300. Stock wheel on a 1993 is 15x6.5 with 215/60 tires which look way too small for wheel wells. I used a tire size calculator which shows the 225/45/17 to be a near perfect fit to stock 93 tires, but they would be even smaller diameter. Will the much wider diameter 235/50/17 fit without any problems with handling and braking? Stock tire for 1995 SC300 is 225/55/16, and tire calculator states 235/50/17 are a close fit to the 95 stock tire? Seems like moving up to 235/50/17 wouldn't be a problem. . . . one last thing, tire calculator stated minimum wheel width for 225/45/17 tire is 7 inches but minimum width for 235/50/17 tire is 6.5 inches -- is this true? seems wierd.

Thanks to any of you tire pros for taking the time to read and respond to this long request.

Right your supposed to go down to 245/45/17. 50s may not look like they will rub, but anybody or anything in your trunk may make your car scrub. Not to mention it will throw your speedometer off.

Right but isn't the 245 tire too wide for a 7" rim? This is the reason I when with the 17" GS wheel, for the 8" width with 245 tires.

225/45 17 is the correct size if you have a 17 x 7 inch wheel on that car. 235/50 17 is 1 inch taller then the original equip. OD.
