Fitting Cadillac XLRV wheels? This page gives the 2006 Cadillac XLRV bolt pattern (5x120.65), centre bore, factory rim size and the offset range for aftermarket and forged Cadillac XLRV rims: the same spec sheet ANKUSI uses when machining forged wheels for this car.
Quick answer: The 2006 Cadillac XLRV uses a 5x120.65 bolt pattern with a 70.3 mm centre bore and M12x1.5 lug nuts. Factory wheels: F: 19x8.5J R: 19x9J. For aftermarket wheels, 20x9J ET40 front / 20x10J ET45 rear sits flush and 20x9.5J ET35 front / 20x10.5J ET40 rear is the most aggressive fit.
Forged wheels for the 2006 Cadillac XLRV — drilled 5x120.65 with a 70.3 mm centre bore, built to the offset you choose. From $220 per wheel, made to order in about 25 days.

| Configuration | Wheel Size & Offset |
|---|---|
| Factory (OE) | F: 19x8.5J R: 19x9J |
| Flush Fitment | F 20x9J ET40 / R 20x10J ET45 |
| Maximum Aggressive | F 20x9.5J ET35 / R 20x10.5J ET40 |
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
With less structural stiffness from the missing roof, a convertible's suspension tuning leans more heavily on unsprung mass control. Forged construction keeps wheel weight down at the same strength rating, which is one less variable working against the Cadillac XLRV's chassis.
The Cadillac XLRV runs a 5x120.65 bolt pattern, 70.3mm center bore, and a F: 19x8.5J wheel from the factory. Our Flush Fitment reference is F 20x9J ET40 / R 20x10J ET45, which tucks the tire under the fender lip on a stock-height Cadillac XLRV. Our Maximum Aggressive reference is F 20x9.5J ET35 / R 20x10.5J ET40 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
The 2006 Cadillac XLRV (Roadster) uses a 5x120.65 bolt pattern with a 70.3mm center bore. Factory wheels are F: 19x8.5J R: 19x9J.
Why the factory spec works for most owners:
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Cadillac XLRV (2006) we drill the 5x120.65 pattern and cut the centre bore to 70.3mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

For a flush look with minimal rubbing, F 20x9J ET40 / R 20x10J ET45 is the recommended starting point on a stock or mildly lowered Cadillac XLRV.
F 20x9.5J ET35 / R 20x10.5J ET40 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.
Case 1: Daily Driver (Factory-Style)
Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: F 19x8.5J ET46 / R 19x9.0J ET46
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: F 20x9.0J ET40 / R 20x10.0J ET45
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: F 20x9.5J ET35 / R 20x10.5J ET40
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Cadillac spec, or want a wheel built to a custom offset for your Cadillac XLRV? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 5x120.65 pattern and the 70.3mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
We do not hold 5x120.65 wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.
In our database, 63 other vehicle entries from 6 makes use exactly the same 5x120.65 bolt pattern and 70.3 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x120.65 is used by 1.6% of the vehicle pages in our English fitment guide (101 of 6,503); 63.4% of those also use a 70.3 mm center bore.
A wheel with a center bore larger than 70.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.5 mm | 70.5 → 70.3 mm |
| 71.6 mm | 71.6 → 70.3 mm |
| 72.6 mm | 72.6 → 70.3 mm |
| 73.1 mm | 73.1 → 70.3 mm |
ANKUSI forged wheels are bored to exactly 70.3 mm for this vehicle, so no ring is needed.
