I have my Xb dropped two inches. I have a set of 18" rims. I wanna know what size tire I can go with. The roads around here suck and am looking to go with something with some side wall on it. Maybe 40 series or 45 series. Please help I am going to get new tires tomorrow

 

I posted a topic here about running 40s on a NF210 drop kit:

Bad roads and 18s don't really mix. Best you could do is go with some 215/40 tires instead without too much rubbing on full lock turns.
