Continental ContiProContact, 225/45 R17 91H SL: articles 15496030000 and 03522590000. This range applies to these exact products; it does not approve another 225 mm tire or a vehicle. Check the full size, article number, wheel and vehicle requirements.

The same nominal size can describe different products: published weights are 20.7 and 24.9 lb, and UTQG grades are 500 AA A and 400 AA A. Both list a 25-inch diameter and 8.9-inch section width on a 7.5-inch measuring rim. Nominal geometry gives 634.3 mm diameter; the published rounded 25 inches converts to 635 mm. These are manufacturer specifications, not our measurements or proof of a calculator error.

How to use this range

Rim width compatibility is a first-pass check, not the whole fitment decision. A tire can be inside the section-width range and still fail because of vehicle clearance, load rating, speed rating, offset, centre bore or local approval rules.

For a final decision, match the tire maker's approved rim range, the vehicle placard and the wheel specification. Wider or narrower rims can change sidewall shape, steering feel and rim protection even when the tire mounts physically.
