Will these fit

[hondadroid]

Hey gius, I found a great deal on a set of winter rims and tires from an infinity q50.
The rims are 18x8 with a +40 offset and a 245 45 18 tire. I understand they are a bit taller then stock and I am ok with that.
My car is a 2017 si
Let me know. Thanks

Rims will fit as the centerbore is 2mm larger on Nissan. However that tire is just way too tall at 26.7" diameter compared to OEM 25.3". I vote no on the tire but the rim will work.

Use 245/40/18 instead

Probably will fit but keep in mind your speedo will be off by a few mph.

Will they fit...yes. Will they rub at full lock or susp travel? Possibly. I wouldn't risk it and damage to your fenders. I would advise if you're that concerned about the wheels/tires to just pick up a set of 17's. Some 245/45/17's would be fine or even 235/45/17's as well would have a half in more sidewall than their 18" counterparts with the same overall diameter tire.

I wouldn't run it personally and I DO currently run a 245/40/18.

People have gotten better about understanding tire sizes and what the numbers mean but I still find that there are people out there who don't know

245 (width)
40 (sidewall height as percentage of width)
18 (rim diameter)
