How to choose tires for the 2008 infiniti G35

The 2008 Infiniti G35 ships from the factory on 225/55R17 tires mounted on R17 wheels. 3 approved fitments are documented for this model year, allowing some flexibility between performance, comfort, and winter compounds. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.

Tire choice on the Infiniti G35 comes down to three trade-offs that matter more than brand loyalty: load index (must equal or exceed the OEM number), speed rating (must match or exceed the placard), and UTQG treadwear (higher means longer life, lower usually means stickier rubber). Owners replacing factory tires with the same compound class, for example all-season for all-season, generally see no change in ride characteristics or fuel economy. Switching categories (performance summer to all-season touring, for example) is where the trade-offs show up at the contact patch.

For 2008 Infiniti G35 owners considering a plus-size upgrade, the safer option is a Plus-1 step (one rim size up with a 10-point aspect drop and ~10 mm of additional section width). Plus-2 is technically viable on this chassis if the alternative-sizes table lists a Plus-2 candidate within tolerance, but expect a meaningful ride-harshness penalty and a tire-cost premium of 30–60% per tire relative to the OEM fitment. For winter use the recommended pattern is one width step down (e.g. from a 235 to a 225) with the aspect ratio bumped up to preserve overall diameter; narrower tires apply higher contact pressure per square inch on snow, which translates directly into shorter braking distances. The plus-size calculator evaluates any specific rim step against this OEM size.

Before purchasing, verify the tire size on the driver-door placard of your specific 2008 Infiniti G35, since trim levels and option packages can shift the original fitment from what is documented here. The placard reading is the authoritative source per FMVSS 110, and dealers will reference the placard rather than aftermarket catalogs when validating warranty claims.

DT*: THE CONTACT STATED THE FRONT DRIVER SIDE TIRE HAD A BULGE PRESENT. FURTHER EXAMINATION SHOWED A CRACK ON THE SIDEWALL TIRE CAUSED IT TO FAIL. THE VEHICLE WAS TAKEN TO A TIRE SHOP, WHO DETERMINED THE PROBLEM WAS DUE TO HITTING A POTHOLE AND NOT A MANUFACTURER DEFECT. THE CONTACT VIEWED MANY SIMILAR COMPLAINTS VIA THE NHTSA WEBSITE ABOUT THIS ISSUE. NO REPAIRS HAD BEEN MADE. THIS WAS A GOODYEAR EAGLE, SIZE: 245/35R19.

NHTSA complaint 600556 · 2005 vehicle

LOW TIRE PRESSURE MONITORING SYSTEMS MUST BE REPROGRAMMED BY THE DEALER IF WHEELS ARE ROTATED, IF A FULL SIZE SPARE TIRE REPLACES A WHEEL THE REPROGRAMMING IS AT CONSUMER'S COST. THIS FORCES CONSUMERS TO HAVE TO GO BACK TO THE DEALERSHIP FOR SOMETHING WHICH USED TO BE DONE AT HOME. I BLAME NHTSA FOR PUSHING TIRE PRESSURE MONITORING SYSTEMS, WITHOUT ENFORCING MANUFACTURERS MAKING IT POSSIBLE FOR CONSUMERS TO SET THEIR OWN TIRE PRESSURES, AND THIS ADDED UNNECESSARY COST TO REGULAR MAINTENANCE WHICH USED TO BE FREE.

Frequently asked questions

What size tires fit a 2008 Infiniti G35?
The OEM tire size for the 2008 Infiniti G35 is 225/55R17 mounted on R17 wheels.. Trim levels and option packages can shift the original fitment; confirm against your specific vehicle's driver-door placard before purchase.
Can I run a different tire size on my 2008 Infiniti G35?
Plus-sizing (larger rim, lower aspect) is possible within ±3% of the OEM overall diameter per the ETRTO safe-fit standard. The Compatible alternative sizes table on this page lists every safe option for the OEM size. Always confirm with the manufacturer or a qualified tire shop before deviating from the placard.
Where can I buy tires for my 2008 Infiniti G35?
Online tire retailers in our affiliate network carry every size documented for this vehicle. Use the Shop online buttons above to compare prices across them; variance of $20–$40 per tire is common between merchants. The <a href="/tools/tire-install-cost-calculator/">install cost calculator</a> estimates the out-the-door including mount, balance, TPMS, and disposal by state.
What is the recommended tire pressure for the 2008 Infiniti G35?
The cold-inflation pressure is printed on the driver-door placard of your specific vehicle and varies by trim, tire size, and loaded vs unloaded condition. Typical OEM front and rear pressures fall between 30 and 36 psi for passenger trims and 32–40 psi for SUV/truck variants, but the placard is the authoritative source.
Can I fit winter tires in a different size on my 2008 Infiniti G35?
Yes; the standard winter-tire fitment pattern is one width step narrower than OEM (e.g. 225 → 215) with the aspect ratio bumped up to preserve overall diameter. Narrower tires increase contact pressure on snow for better traction. The Compatible alternative sizes table includes any winter-friendly options that fall within ±3% OD for this vehicle.
How often should I rotate the tires on my 2008 Infiniti G35?
Every 5,000–7,500 miles is the typical OEM recommendation for passenger vehicles. AWD vehicles and high-torque trucks benefit from the shorter interval. Documented rotation history is also a tire-warranty prerequisite; most manufacturer treadwear claims require rotation receipts at the warranty inspection.

For broader tire questions; replacement timing, UTQG, EV-specific tires, winter swaps; see the tire FAQ.
