would 40 profile tires fit with no rubbing on 18's with an H&R sport drop? thanks!

 

yes, given your wheel offset is correct (if you have after-market wheels).

 

How wide are your rims? What are the offset of those rims. A general rule of thumb is to go at least +45 offset if you have 7.5" rim (with 18" diameter). I'm sure you could go lower but if you have issues with rubbing (ie system in the trunk/carry 3 passengers in the back), then the higher the offset, the better.

BTW, I have a Comptech drop (silver springs) and OEM shocks. My summer setup is: 235/40/18 Toyo Proxies4 on 18x7.5" Volk Racing SE37. I've rubbed maybe 5-10 times (tops) when I had 3 people in the back. I've never rubbed with OEM rims.

 

yeah, i know about the offset fitments... cool, sounds like 40 offset will work then, thanks guys!
