Couldn't locate the parts for 2013 Civic Si Sedan. Front struts are an Anomaly found them at Capital autoparts. Great service and great parts. Shipping by CanPar sucked however

Great customer service. I placed an order for wheels and tires and it was an easy transaction. Make sure you read the expected lead times for delivery however. I misread that part, but the order did arrive in the correct timeframe stated. The Hostile rims and Hercules tires look great. Thank you

Frequently Asked Questions — Tectonic THTWSTPCR45100
What vehicles does the Tectonic THTWSTPCR45100 fit?
The Tectonic THTWSTPCR45100 fits 50 vehicle applications including 1991-1994 Audi 100, 1992-1994 Audi 100 Quattro, 1989-1991 Audi 200, 1989-1991 Audi 200 Quattro, 1984-1988 Audi 5000 and 45 more. Check the full fitment list above to confirm your vehicle.
What size is the Tectonic THTWSTPCR45100?
The Tectonic THTWSTPCR45100 is a 225/45R18 tire. The three numbers are section width in millimetres, aspect ratio (sidewall height as a percentage of width) and rim diameter in inches. Check the size printed on your current tire sidewall or door-jamb placard before ordering.
What do the load index and speed rating of the Tectonic THTWSTPCR45100 mean?
For the Tectonic THTWSTPCR45100, a load index of 95 means each tire is rated to carry up to 690 kg, and a speed rating of T means it is rated for sustained speeds up to 190 km/h. Choose a tire whose load index and speed rating meet or exceed your vehicle manufacturer's specification.
Is the Tectonic THTWSTPCR45100 an all-season or winter tire?
It is listed as Winter.
What is the bolt pattern of the Tectonic THTWSTPCR45100?
The Tectonic THTWSTPCR45100 has a 5X112 bolt pattern (number of lugs by the diameter of the circle they sit on). It must match your vehicle's bolt pattern exactly.
What offset does the Tectonic THTWSTPCR45100 have?
The Tectonic THTWSTPCR45100 has an offset of 45. Offset is the distance from the wheel's mounting surface to its centreline; a lower or negative offset pushes the wheel outward, a higher offset tucks it inward, which affects suspension and fender clearance.
What is the center bore of the Tectonic THTWSTPCR45100, and do I need hub-centric rings?
The Tectonic THTWSTPCR45100 has a 66.6 center bore. If your vehicle's hub is smaller than the wheel's bore, hub-centric rings fill the gap so the wheel centres on the hub rather than on the lug nuts; if the hub is larger than the bore, the wheel will not fit. Hub rings are sold separately unless the listing says otherwise.
What are the shipping options for the Tectonic THTWSTPCR45100?
Shipping options for the Tectonic THTWSTPCR45100 are shown during checkout and may vary by item, address, and availability. Eligible orders over $99 may qualify for free shipping, with some exceptions. Call 1-866-461-2787 if you need help confirming shipping or pickup before ordering.

Is the 225/45R18 Tectonic Winter Tire & Steel Wheel Bundle for 2015-2026 Mercedes-Benz C300 (4Matic, Base) a direct fit replacement?
