Nominal tire width can narrow the search, but it cannot approve a tire-to-rim combination. Use the chart as a screening estimate only, then confirm the approved rim-width range for the exact tire make, model, size and service description. Vehicle clearance, wheel offset, load rating and local rules still need separate checks. ## Rim-width screening chart These editorial ranges group common passenger-car section widths by J-rim width. They are deliberately labelled as screening estimates: two tires with the same nominal width can have different approved rim ranges. | Rim width | Screening minimum | Screening maximum | | --- | --- | --- | | **5.0J** | 135 mm | 155 mm | | **5.5J** | 145 mm | 175 mm | | **6.0J** | 155 mm | 185 mm | | **6.5J** | 175 mm | 205 mm | | **7.0J** | 185 mm | 215 mm | | **7.5J** | 195 mm | 225 mm | | **8.0J** | 205 mm | 235 mm | | **8.5J** | 215 mm | 245 mm | | **9.0J** | 225 mm | 255 mm | | **9.5J** | 235 mm | 265 mm | | **10.0J** | 245 mm | 275 mm | | **10.5J** | 255 mm | 285 mm | | **11.0J** | 275 mm | 305 mm | ## What makes a rim width approved? Approval belongs to the exact tire specification, not to the section-width number by itself. ETRTO says only approved rim sizes should be used; Michelin likewise directs owners to the manufacturer rim-width range for the tire. The current manufacturer data sheet is therefore the final tire-to-rim reference. ## How to verify a combination - Identify the complete tire specification, including make, model, size, load index and speed symbol. - Find the approved rim-width range in the current tire manufacturer data sheet or fitment tool. - Confirm wheel diameter, bead-seat width, load rating, offset, centre bore and bolt pattern. - Verify strut, brake, fender and full-lock clearance on the exact vehicle and trim; ask a qualified tire professional when documentation is unclear. ## Width within an approved range still changes behavior A rim near the narrow end generally gives a more curved sidewall and slower steering response; a rim near the wide end gives a straighter sidewall and quicker response. The exact section width, ride and protection change depend on the specific tire construction, so TireFitLab does not apply a universal millimetres-per-half-inch correction. ## This chart does not verify - manufacturer approval for a particular tire product or load version; - vehicle, suspension, brake or body clearance; - wheel strength, offset, centre bore or bolt-pattern compatibility; - load/speed suitability, inflation pressure or legal approval. *Safety boundary: a value inside the screening range is not a safe-fit verdict. If the exact tire data sheet does not list the wheel width, do not treat this chart as permission to mount it.* ## Rim-width sources reviewed The approval boundary and verification method were checked against current ETRTO publication material and Michelin manufacturer guidance. The numeric screening table is TireFitLab editorial data, not a reproduction of a current ETRTO or T&RA approval table. - [ETRTO recommendations: use only approved rim sizes](https://www.etrto.org/media/j05fjxrd/etrto-recommendations-edition-2-september-2024.pdf) - [ETRTO Standards Manual catalogue: current tire and rim standards](https://www.etrto.org/Publications/Available/Standards-Manual) - [Michelin FAQ: use the manufacturer rim-width range for the exact tire](https://www.michelinman.com/auto/assistance/michelin-faqs) Checked: 2026-08-21 ## More tools - [Tire size calculator](https://tirefitlab.com/tire-size-calculator/) - [Plus sizing guide](https://tirefitlab.com/learn/plus-sizing/) - [Bolt pattern guide](https://tirefitlab.com/learn/bolt-pattern/) - [Load index chart](https://tirefitlab.com/learn/load-index/) - [Wheel offset guide](https://tirefitlab.com/learn/wheel-offset/) - [Tire sidewall markings decoder](https://tirefitlab.com/learn/tyre-sidewall-markings/) - [Tire & wheel reference guides](https://tirefitlab.com/learn/) ## Detailed reference pages Choose a common value or size to open its calculated data and explanation. - [5.0J](https://tirefitlab.com/learn/rim-width/5j/) - [5.5J](https://tirefitlab.com/learn/rim-width/5-5j/) - [6.0J](https://tirefitlab.com/learn/rim-width/6j/) - [6.5J](https://tirefitlab.com/learn/rim-width/6-5j/) - [7.0J](https://tirefitlab.com/learn/rim-width/7j/) - [7.5J](https://tirefitlab.com/learn/rim-width/7-5j/) - [8.0J](https://tirefitlab.com/learn/rim-width/8j/) - [8.5J](https://tirefitlab.com/learn/rim-width/8-5j/) - [9.0J](https://tirefitlab.com/learn/rim-width/9j/) - [9.5J](https://tirefitlab.com/learn/rim-width/9-5j/) - [10.0J](https://tirefitlab.com/learn/rim-width/10j/) - [10.5J](https://tirefitlab.com/learn/rim-width/10-5j/) - [11.0J](https://tirefitlab.com/learn/rim-width/11j/) [Last reviewed: 2026-08-21](https://tirefitlab.com/methodology/) Seasonal check ## Planning a long summer drive?
