We’re purchasing a used 2009 Infinity G37 Coupe. The manufacturer sold it with a staggered setup, front 18x8 w/ 225/50/18 and rear 18x8.5 w/ 245/45/18. It has new tires but they are all 245/45/18’s. Reviewing the tire manufacture’s specs both the 8 and 8.5s are within range. The tire brand/model is not sold in the 225/50/18 size.
So the options are:
- Drive it with 245’s all around (low cost)
- Purchase to new front 225s of a different brand/model. (medium cost)
- Purchase 4 new tires 225s/245s of all the same brand/model (high cost)
Is it safe to drive w/ the same tires all around? The sidewall deflection will different between F/R.
I’m assuming the 8s should go up front, so there is more deflection on the fronts to promote understeer.
