Valve Stem and TPMS

The N70 uses rubber valve stems from the factory. Aftermarket wheels require compatible metal valve stems. If the original valve stem is metal, it may be reused. Before installation, confirm compatibility with the wheel valve hole and the tire pressure monitoring sensor.

Wheel Load Requirement

The factory wheels do not display a load rating. MAKSTTON therefore estimates the minimum wheel load rating using a 1.2 safety factor based on the 3,049 kg gross vehicle weight rating:

3,049 kg ÷ 4 × 1.2 = 914.7 kg

MAKSTTON recommends a minimum load rating of 915 kg per wheel.

Before selecting a wheel, also verify the manufacturer's published load rating, mounting method, and the vehicle's actual fully loaded condition.

Measured Wheel-to-Fender Clearance

Measurements were taken with the air suspension at its lowest setting. Values are in mm.

Measurement Front left Front right Rear left Rear right
Fender lip to wheel edge 34 30 38 34
Fender lip to tire sidewall 24 20 28 24
Suspension height 50 45 68 70

Front inner tire sidewall-to-suspension clearance is approximately 1.5 fingers. Vehicle assembly tolerances may cause differences between the left and right sides.

MAKSTTON Custom Fitment Recommendation

The following configurations are based on factory tires or the corresponding wider tire options. In each configuration, the wheel edge sits inside the fender:

Configuration Tire Specification Front Wheel Rear Wheel Wheel-Edge Position
19-inch, factory tire 245/55R19 19×8.0J ET27 19×8.0J ET27 Approx. 10–14 mm inside
19-inch, factory tire 245/55R19 19×8.5J ET33 19×8.5J ET33 Approx. 10–14 mm inside
21-inch, factory tire 255/45R21 21×8.5J ET27 21×8.5J ET27 Approx. 4–8 mm inside
21-inch, wider tire 275/45R21 21×9.0J ET33 21×9.0J ET33 Approx. 4–8 mm inside

Frequently Asked Questions

What are the Xiaomi N70 bolt pattern and center bore?

The Xiaomi N70 uses a 5×120 bolt pattern (PCD). The published center bore is 64.5 mm. The measured wheel center bore is 64.634 mm, and the measured hub diameter is 64.52 mm. MAKSTTON recommends a custom wheel center bore of 64.55 mm for this vehicle.

What are the factory Xiaomi N70 wheel and tire specifications?

The measured vehicle uses 19×7.5J ET41 wheels and 245/55R19 tires at both the front and rear.

Can 19-inch aftermarket wheels use the factory tires?

Yes. The guide lists 19×8.0J ET27 and 19×8.5J ET33 configurations for the factory 245/55R19 tires. Review the final fitment table, and confirm wheel load ratings and actual vehicle clearance before installation.

Can the Xiaomi N70 be upgraded to 21-inch wheels?

Yes, provided the wheel width and tire specification are matched correctly. This guide lists 21×8.5J ET27 / 255/45R21 and 21×9.0J ET33 / 275/45R21. A documented vehicle runs 21×9J ET35 / 275/45R21. Confirm brake, suspension, wheel-arch, and dynamic steering clearance before installation.

What minimum wheel load rating does the Xiaomi N70 require?

Using the 3,049 kg gross vehicle weight rating and a 1.2 safety factor, the calculated load per wheel is 914.7 kg. MAKSTTON recommends a wheel load rating of at least 915 kg per wheel. Also verify the wheel manufacturer's published rating and the vehicle's actual fully loaded condition.

How should the factory fender clearance measurements be interpreted?

Measurements were taken with the air suspension at its lowest setting. Fender lip-to-wheel edge clearance was 34 / 30 mm at the front and 38 / 34 mm at the rear. Fender lip-to-tire sidewall clearance was 24 / 20 mm at the front and 28 / 24 mm at the rear. These measurements indicate available inward or outward adjustment but do not replace final clearance checks on the assembled vehicle.

Can the factory bolts, valve stems, and TPMS be reused?

The factory wheel bolts are M14×1.5, with 31.4 mm thread length, a 60° conical seat, strength grade 10, and a 21 mm hex. They may be reused only when the new wheel's seat type and thread engagement match. The factory rubber valve stems should not be reused with aftermarket wheels. Tire pressure monitoring sensors require compatible valve stems and mounting seats.
