Which 4 measurements decide if a wheel fits?

Match diameter, PCD, center bore and offset (ET). Send your car model or the numbers from your current wheels - fitment is confirmed within 24 hours before any payment.

Can I mix sizes or PCDs in one container?

Yes. Mixed 18-inch fitments ship in one 20ft/40ft container - most wholesale customers combine 2-4 PCD groups per shipment.

Do you ship small trial orders?

Yes. Sample sets of 4 pcs and pallet quantities are available, payable by PayPal or card. Container orders run on T/T 30/70.

Do you export 18-inch wheels to Dubai and Saudi Arabia?

Yes. UAE and Saudi Arabia are our busiest GCC lanes - mixed containers sail to Jebel Ali and Dammam weekly, with SASO certificate and commercial invoice documents issued per shipment.

How are your alloy wheel prices calculated for wholesale buyers?

Pricing is FOB Ningbo per SKU and scales with quantity per model - mixed PCDs and finishes can share one container with no minimum per design. Send your SKU list for a same-day FOB quote.

Do you stock 15, 16 or 17 inch wheels?

Our warehouse program concentrates on 18 inch - the global volume size with the fastest turnover. 15 to 26 inch designs from 4,600+ molds are available on production orders; ask which sizes suit your market.

Can I become a HAIJI wheels distributor?

Yes. We work with importers, dealers and fleet programs on dealer pricing tiers, area protection and sample-set trials before the first container.

FAQ — Porsche 911 wheels

Why is 5×130 hard to source?

Porsche’s pattern is shared with almost no other brand, so most aftermarket makers skip it. We machine 5×130 forged to order – CB71.2 exact, center-lock or 5-bolt.

Center-lock or 5-bolt for my 992?

Base Carrera uses 5 bolts; GTS/Turbo/S use center-lock. Send your axle spec – we build to the exact hub.

MOQ and lead time?

1 set = 4 pcs. 3D CAD clearance drawing in 24 h, production 15-20 days, door-to-door courier worldwide.

How is fitment confirmed before I pay?

Send your car model, year and (if known) your current wheel specs. We return a written fitment confirmation — PCD, bore, offset, load rating and brake clearance — within 24 hours, before any payment.

Can I mix this fitment with other PCDs in one container?

Yes — mixed-PCD loading is our standard: combine 2-4 fitment groups per 20GP (~300 pcs) or 40HQ (~720 pcs), one B/L, one inspection certificate.
