Discussion of Infiniti's amazing (and underrated) sport-luxury crossovers, the EX35 and EX37. For 2014, the EX series will be renamed QX50, in line with Ininfiit's new naming conventions.

Installing 2003 Infiniti G35 Coupe Rims/Tires on 2008 Infiniti EX35

Postby Silverfox555 » Thu Mar 14, 2019 12:05 pm

Hoping you guys/gals can share some insight. I was hoping to put my old 2003 Infiniti G35 coupe rims and tires on my 2008 Infiniti EX35. Prior to owning my EX35, I had actually put the G35 rims and tires on my 2008 Infiniti G37 coupe and it fit fine without scraping calipers or anything. Here's some info:

2003 Infiniti G35 OEM rim sizes:
- Bolt Pattern: 5x114.3
- Front Rims: 17x 7.5"
- Rear Rims: 17x8.0"
- Front Tire Size: 225/50R17
- Rear Tire Size: 235/50R17

2008 Infiniti EX35 OEM rim sizes (17" tires):
- Bolt Pattern: 5x114.3
- Front and Rear Rims: 17x 7.5"
- Front and Rear Tires: 225/55R18 97V

Of course, the G35 rims are staggered. The EX35 has enough clearance for 18" tires (currently it has 18" tires). Do you guys/gals foresee this working? Are there other specifications I need to consider to see if it'll work?

I know some of you might say it'll throw the odometer off a bit. I am okay with this. Also, in what instance would I require spacers?

Besides the specs you've listed and the shape of the wheel itself, offset is the key determining factor of whether the wheel will clear the brake caliper and other suspension components, or whether you'd need spacers. In this case, the G35 wheels have different offsets from the EX35 wheels (I assume you are referring to the 18" EX wheels since you mentioned the tire size as 225/55-18, and not the 17"). The G35 offsets are 30mm (at least the fronts are), while the 18" EX35 wheels have a 45mm offset. What this means is that the G35 wheels will sit further away from the wheel hub by 15mm, and stick out a bit more than the EX wheels. Not necessarily a bad thing looks and performance-wise, though it adds a slight bit more stress on the wheel bearings since the wheels are farther outboard (how much added stress is hard to say). Most aftermarket options for the EX seem to stick with around 35-38mm of offset (at least from a quick search on Tire Rack).

You can visualize all of this on

The diameter difference between 225/50-17 and 225/55-18 is about an inch (~4%) so the speedo error won't be too bad, but it will be about 3mph as you get towards highway speeds.

Is your EX35 AWD or RWD? If it's AWD, I'd recommend that you get tires with matching diameters for the front and rear wheels. If it's RWD, it probably wouldn't be as much as an issue, but the difference in tire diameter might just be enough to cause issues with the ABS/Stability control system in certain situations. There's a forum member here EX-KAT-35 who I beleive is running on staggered wheels with no issues, but I don't recall the details of her setup. I think her tires were pretty close in diameter though.

By the way, the OEM tire specs for the EX35 on 17" wheels is 225/60R17 98V.
