I don't know jack about tires. I had 245-40-17's all around awhile back and the fronts rubbed my struts. I really liked how the back felt so I decided to keep that size. It's time for new tires and I currently have 215's on the front and I want to go to a larger size to fill in the space in the fenders. I think 225's will do but could I get 235's on the front without them rubbing my struts. I don't have rolled fenders either.

 

i have some z wheels with 225's all the way around and the front rub pretty bad so i had to put spacers...but im also 5 lug but they shouldnt rub with stock se wheels

 

Cool, thanks man!

 

hmm not sure about s13's but on my s14 im running 350z track wheels with 235 up front and 285 in the rear no rubbing

 

wheel specs? did you try spacers with the 245 tires?

 

Its all about wheel spacing, sizing, and offsets. You could run a 315 up front without hitting the struts assuming you had the right offset (and body mods). A 325 is not a problem, but would will need a proper sized wheel, something in the 8" wide + range and a proper offset such at +30 or lower.
