An Infiniti's tire needs come down to what kind of vehicle it actually is underneath the badge: the QX80 is a heavy body-on-frame SUV built on the Nissan Patrol platform, the Q60 is a sport coupe that runs a staggered performance fitment on its quickest trim, and the QX60 and Q70 both stick to simpler, square setups. Infiniti doesn't publish a tire-approval marking the way some German luxury brands do, so match the size and load index on your door sticker rather than hunting for a code.
Infiniti splits into crossovers, a heavy SUV, and a sport coupe
The QX60 is a three-row luxury crossover built around ride comfort, and the QX80 is a genuinely different animal: a body-on-frame SUV based on the Nissan Patrol platform, weighing over 5,600 lbs fully loaded and used as a family hauler and tow vehicle. The Q60 sport coupe and its Q70 sedan sibling share the twin-turbo V6 platform but wear it differently — the Q60 leans into performance handling, while the Q70 stays closer to conventional luxury touring.
That range means the right tire for one Infiniti says almost nothing about the right tire for another. A QX80 owner is thinking about load capacity and towing. A Q60 owner is thinking about grip and whether they've got the staggered Red Sport fitment.
Infiniti doesn't run an OEM tire-approval program
Audi has AO. Mercedes has MO, MO1, and MOE. Porsche runs N0 through N3. Infiniti has no equivalent public marking — no special code stamped into a sidewall meaning "Infiniti-approved." Infiniti specs a size, a load index, and often a specific OEM tire model by trim and generation instead, and that information lives on the door jamb placard. There's no letter grade to chase on a replacement tire; matching the size and load rating on your sticker is what actually matters.

Staggered fitments are real on the Q60, not on the Q70
It's worth being precise here, because the two cars get lumped together and they aren't the same. The Q60 Red Sport 400 runs a genuine staggered performance fitment, 255/35R20 up front and a wider 275/30R20 in the rear, built to optimize the rear-drive-biased handling the way a performance coupe should. Standard Q60 trims run a square 245/40R19 or 255/40R19. The Q70, on the other hand, sticks to square sizing across its lineup, 245/50R18 standard with an optional 245/40R20 — no staggered setup. If you're shopping tires for a Q70, you only need one number per axle. If you're on a Red Sport Q60, you need front and rear sizes separately, and they can't be rotated with each other.
QX60 vs QX80: crossover weight vs body-on-frame weight
The QX60 is the lighter of the two SUVs, and its tire story is mostly about wheel size: the current L51 generation runs 255/60R18 on the base Pure trim and steps down to a lower-profile 255/50R20 on Luxe, Sensory, and Autograph, a sidewall short enough that pothole damage becomes a real concern worth planning for. The QX80's story is about raw weight — at over 5,600 lbs fully loaded on the Patrol-based body-on-frame platform, load index compliance isn't optional. Never install a QX80 replacement with a lower load index than what's on the door sticker, especially if you tow.
What to check before you buy, and the door jamb sticker
Confirm your QX60's generation before shopping, since the size changed meaningfully between the L50 (2013–2021) and L51 (2022+) platforms, and trim determines wheel size on the newer car. On a Q60, confirm whether you're on a standard trim or the Red Sport 400's staggered setup before you buy just one size. On a QX80, load index and towing needs come first. Whatever you drive, the tire and loading placard on the driver's door jamb is the final word — it lists the exact size, load index, and pressure Infiniti certified for your build, and it overrides any general guidance here.
Infiniti models covered in this hub — OEM sizes and what changes by trim
| Model | Generation / years | Common OEM sizes | What it changes |
|---|---|---|---|
| Infiniti QX60 | 2013–2021 L50 gen; 2022–current L51 gen | L50: 235/65R18 (235/55R20 optional). L51: Pure 255/60R18, Luxe/Sensory/Autograph 255/50R20 | 20-inch L51 trims run a low-profile sidewall with elevated pothole risk |
| Infiniti QX80 | 2014–current | 275/60R20 (standard on most trims), 275/50R22 (higher trims) | Body-on-frame, Nissan Patrol platform — over 5,600 lbs fully loaded, load index is critical |
| Infiniti Q60 | current generation | 245/40R19 or 255/40R19 (standard, square); 255/35R20 front / 275/30R20 rear (Red Sport 400, staggered) | Red Sport 400 runs a genuine staggered fitment — cannot rotate front to rear |
| Infiniti Q70 | discontinued 2019 | 245/50R18 (standard), 245/40R20 (optional, 3.7/5.6 trims) | Square fitment across the lineup — no staggered sizing, unlike the Q60 Red Sport |
Frequently asked
What tire size does my Infiniti need?
It depends on the model, generation, and trim. The QX60 ranges from 235/65R18 to 255/50R20 depending on year, the QX80 typically runs 275/60R20 or 275/50R22, and the Q60 uses either a square 19-inch fitment or a staggered 20-inch setup on the Red Sport 400. Check the tire and loading placard on your driver's door jamb for your exact build.
Does Infiniti have an OEM tire-approval marking like BMW or Mercedes?
No. Infiniti doesn't run a public tire-approval program with a special sidewall code the way Audi (AO) or Mercedes (MO) do. Infiniti specs a size, load index, and often a specific OEM tire model per trim on the door jamb sticker instead, with no equivalent marking to look for on a replacement.
Does my Infiniti have a staggered tire fitment?
Only if you're on a Q60 Red Sport 400 — that trim runs a genuine staggered setup, wider in the rear than the front. Standard Q60 trims and the Q70 both use square sizing, the same size on all four corners. Check your door sticker if you're not sure, since the difference determines whether you need two sizes or one.
Why does the QX80 need a specific load index?
The QX80 is a genuinely heavy body-on-frame SUV, over 5,600 lbs fully loaded, built on the same platform as the Nissan Patrol. Its towing and payload capability only holds up with tires rated to match. Dropping to a lower load index than the door sticker specifies risks overheating and failure under a real load.
Should I worry about pothole damage on my QX60?
More so on the Luxe, Sensory, and Autograph trims, which run a lower-profile 255/50R20 tire with less sidewall to absorb an impact. The base Pure's 255/60R18 has more cushion. Either way, check tire pressure monthly and consider road hazard coverage if you're on the 20-inch package and drive rough roads regularly.
Where can I get Infiniti tires installed near me in West Georgia?
We match you with local shops in Carrollton and the wider West Georgia area that stock or can order your Infiniti's size, whether that's a common QX60 fitment or the Q60 Red Sport's staggered performance set.
