Maximum TIRE(Rubber) fitment thread

[dorkidori_s13]

So ive picked up a set of Super Advan Generation 2s that are 17x8.5 +30 and 17x9.5 +38.



question 1: ive never run wider wheels with higher offsets (without running 25mm spacers). im thinking the rears will clear the coils, but the fronts im pretty sure are going to wind up rubbing the springs. anyone have experience with these sizes/offsets? im currently running Fortune Auto V4 coils that have the eccentric adapters on the top holes of the brackets.

question 2: im not going for the hella flush look, but if i do add spacers, i would like to push the wheels out just a bit so they sit flush with the fenders (not super low). im thinking 15mm bolt on spacers, i want to keep a good amount of tire on these with minimum stretch. any input on good tire sizes to run. i was planning on 225/40R17 upfront and 245/40/R17 out back. my rear fenders are rolled and not pulled. front fenders are untouched.

please no flaming, im new to the proper fitting tire world and i need to get the tires ordered next week as the wheels are showing late next week i believe. any positive input would be appreciated

I have a set of Panasport G7 C5C2's that are similar sizes

17x8.5 +38 Front 245/40/17 Added a 30mm spacer (effective +8)
17x9.5 +40 Rear 255/40/17 Added a 20mm spacer (effective +20)

Wheels sat perfect in my opinion. Front fenders are rolled flat and the rears have a slight pull. Front camber at -3.2, rear camber at -1.2

Back in 2006, I had the following on my S13 with nothing more than a roll. The fronts were VERY close to hitting the coil, but they DID clear... you will obviously have an additional 2mm of clearance up front. I did not have the car near as low as I do now though:

18×8.5 +32 245/40
18×10 +44 275/35

i was definitely using your car as a point of reference for what tire size to run for sure! i think initially im going to try 235 up front and 255 out back to see how that works. i need the wheels to get here first though to check clearance and all that jazz. cant move forward with tires until that happens ive seen various people say that Fortunes have clearance issues with anything under +25, but none of them have messed with the eccentric adapters in their upper mounts yet sooooooo... wont know til the wheels are here and on the car.
