RTX Wheels: Alloy & Steel Wheels

No vehicle fitment is attached to the RTX Wheels listings on this page. Each wheel is described by its measurements instead, so the page is most useful when you already know the figures your car, SUV or truck needs. Every RTX title spells them out. Take 17x7.5 5x127 +35mm: a 17-inch diameter, a 7.5-inch width, five studs on a 127 mm circle, and a +35mm offset.

Here is what each figure decides. Diameter and width set which tires will mount and how the sidewall sits on the rim. The bolt pattern has to be identical to your hub; 5x114.3, 5x127 and 4x100 are all different, and none of them will cross over. Offset is the distance from the wheel's centreline to its mounting face. A higher positive number, such as +45mm, tucks the wheel further into the arch; a lower one, such as +35mm, pushes it out toward the fender.

To find your own numbers, look at the size cast or stamped on the back of your current wheels and check the bolt pattern and offset in your vehicle's specifications. If you are moving to a wider wheel, keep the offset close to the original unless you have measured clearance at the strut, the brake caliper and the fender lip. RTX sizes include small wheels such as 14x5.5 4x100 as well as 17-inch sizes such as 17x7 5x114.3.

To fine-tune where a wheel sits without changing it, see wheel spacers and adapters, or browse wheels and tires for other brands. Because these wheels carry no vehicle list, match them by the figures in the title rather than by vehicle. Priced in Canadian dollars and shipped across Canada.
