I currently have 235/45/17 on my 1995 Lexus SC 400 however, i would like to increase the height by 2 sizes; ?what do your recommend
The overall tire height doesn't change as the aspect ratio (sidewalls) get smaller like 225x55x16's , 235x45x17's, or 255x35x18's are all about 28" tall. And the sidewalls get smaller by inch by inch. Discount Tire Co. is good with plus sizes & custom wheels. They have charts & formulas for this. Check with them in person or online to see if 18's or bigger will fit.
