I am getting 17X7 wheels and I am wondering what is the fattest (widest) tire I can put on a 1993 240SX SE with 40 offset and 5 1/2 backsetting?  Also, what tire and wheel combo gives the optimal performance for this car?
Thanks.

240/45/17 is the widest I'd run on a 7" wide tire. You might be able to run a little bigger but it might look and  handle funny.

I do not think I've seen a 240/45/17 size tire before, is it uncommon?  If I cannot find that would a 235/45/17 work?

Also is this tire the best for optimal performance?

215/45/17 would be the overal best for the size of the rim. I figured you asked for the widest.

I just got some 16x7.5" rims. Should I get 205/50/16, 225/45/16, or bigger? Application will be street and AutoX...Kuhmo ECSTA 712 (there aren't any 215 with the right sidewall for this tire).

I was wrong about the 240/45/17 :\ The 235/45/17 would probly be it for the 7" wide rim.

7" wide can start with a 195 width. the sidewall will roll tworad the middle of the tread "/"
A 205 width will be more flush but still rolling tworad the center of the tread.

A215 will be straight flush with the rim lip "|"

A225 would be a MAX width for a 7" wide rim, and the sidewall will begin to lean out away from the center of the tread"\"

cornering wise a 205 or a 215 is best for minimal sidewall deflection.
A 225 width will make the driving more vuage and the sidewall will take alot of abuse and scruff.

wav399 · 06-22-2001, 09:43 PM

Sorry but what were those last couple of lines?  And would that mean a 235 might even pop off the rim on hard cornering?

Mr Rose · 06-22-2001, 11:13 PM

205 or a 215 widht is best
225 is for looks, not handling. 195 is too narrow, but some times needed to clear suspension parts.

so a 215 tire would fit perfect, clearing the suspension parts and not rubbing at all?<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>
