My wheels will be here soon, and I got the right offsets I needed, but I'm not really sure what size tires I should get. the front it 18X8.5 and the rear is 18X10. Anyone wanna clue me in on tire sizes. I'm not gonna lie, but I know know cars, but I don't kow jack about tires. all I know is that I want a 40 series tire. Any help would be great guys.

What are you driving? 18x10 (for example) is not an easy fit on the rear of an IS300...

If it's a GS or SC, typically guys are doing 245/40-18 and 275/35-18
Another option would be 235/40-18 and 265/35-18 - but the 265 is pretty narrow for an 18x10, and will appear a bit 'stretched.'

I would guarantee the 235/40 18 and 265/35 18 to fit with the correct offset wheels on a 93 SC300, I think there are guys here who have gone a little more aggressive though.
