The BMW iX is the BMW electric flagship SUV — a very large, very heavy EV (over 5,600 lbs) with air suspension and a premium positioning that competes with the Audi e-tron GT-X and Mercedes EQS SUV. Tire selection must handle the exceptional weight, maintain BMW sport dynamics, and prioritize low rolling resistance for the 300+ mile range BMW quotes.
BMW iX tire sizes
The iX xDrive40 and xDrive50 use 235/60R20 on standard 20-inch wheels — a square, non-staggered fitment shared across every trim including M60. The optional 21-inch wheels use 255/50R21, and the optional 22-inch wheels use 275/40R22, both also square rather than staggered.
BMW specifies Pirelli P Zero All Season Plus (in several sizes) and Bridgestone Turanza EV as OEM on the iX. Both are EV-optimized tires with foam acoustic lining. Verify your exact size on the door sticker.
Best tires for the BMW iX
Pirelli P Zero All Season Plus Elect (235/60R20) — one of the OEM choices on the iX. EV-optimized with foam acoustic lining, low rolling resistance, and all-season capability. Specifically tested on BMW EV platforms. Top recommendation for owners who want to stay with the OEM-spec tire choice.
Bridgestone Turanza EV (235/60R20) — the other OEM choice on the iX. Foam acoustic technology, EV weight distribution optimization, and low rolling resistance compound. Available in 235/60R20 and competitive with the Pirelli.
Continental CrossContact LX25 (235/60R20) — the quietest non-EV-specific all-season for the iX. Very low road noise, excellent wet traction, 70,000-mile warranty. A good alternative for owners who do not need the specific EV engineering.
Frequently asked
What tire size does the BMW iX use?
iX xDrive40 and xDrive50 (20-inch, standard): 235/60R20. Optional 21-inch: 255/50R21. Optional 22-inch: 275/40R22 — all square, not staggered. Verify on the driver door sticker.
How much do BMW iX tires cost?
235/60R20: $215 to $320 per tire. 255/50R21: $240 to $360 per tire. A full set of four on standard 20-inch wheels installed runs $860 to $1,280.
Will my tire choice affect the iX's range?
Yes, and on a heavy EV it's meaningful. A tire with high rolling resistance can trim real miles off each charge, while an EV-optimized replacement protects the range BMW quotes. If maximizing miles matters, ask specifically for a low-rolling-resistance option. A shop can point you to the efficient tires in your size.
Do I have to use an EV-specific tire on the iX?
It's the sensible default, since EV-tuned tires are built for the weight and often add an acoustic foam liner for the quiet cabin. If you choose a standard tire, match the load rating for the iX's considerable weight and favor low rolling resistance. A local shop can help you weigh the trade-offs.
Why do EV tires like the iX's cost more?
They're engineered for heavier loads, higher torque, and low noise, often with special compounds and foam lining, and the large diameters add cost on their own. The upside is they're built to last under EV stress and protect your range. A shop can quote your exact size and show you where the value lands.
