So I got a new set of wheels from a member of a nissan infiniti Facebook group I am in. The fronts are 245 35zr19 and the rears are 285 35zr20. Fronts are 9 inches wide and rear are 10.5. The fronts are spinning 784 revs per mile and the rears at 724. The difference of 60 is definitley over the 3% I've seen through my research. This i think is leading to basically every braking/traction related light on my dash illuminating after a bit of driving. I cant seem to wrap my head around this concept well enough to figure out what size tires I need to change to. The offsets are +35 btw, and I have had to trim the bumper bracket and wheel well liner to save from scraping, and that seems to have fixed that problem..Can someone possibly lend me some brain power so I can sleep at night?

 

Would 255 40 19 possibly get it close enough? 3.04% is still over, but is the system still going to freak out? I think it may help loose some of the front wheel gap

 

Put a 245/40/19 in front and you & your G will be happiest!

 

Luckily I had one of my rears from the take offs and a used shop had a cheap one for me to test it with tonight, works perfect now, and wheel gap is significantly lower! Thank you! Now to go pick up a new set for all 4 and an alignment!
