Is this size of tires a good match??????

[jaime1980]

I have a 91 240sx and I just bought some rims they are 18x7.5 and 18x8.5 I just need some tires. Im thinking of going with 225/40/18 and 245/40/18 in the rear. Any body knows if thats a good set up for a daily driver?? Because on my old wheels I had some 35's on profile and they were not all that for daily driver.........

That sounds about right. Maybe a 45 or 50 sidewall if you want a better ride. Depends more on the look you're going for though.

kinda looks like z32 sizes.50mm side walls have to look like crap on a 18s. Stick with the 40s plz.

The side wall number reflects the % of the width of the tire, not the sidewall in mm's.

What's the stock tire, to compare the overall diameter.
