How do I know if rims will fit my tires?
You will see a series of letters and numbers that will look like this for example: 205/55R16. This will confirm the size of the tires on your vehicle. Make sure all 4 tires read the same size, as some vehicles come with staggered fitments which means the front and rear wheels and tires can be different sizes.
What does ETRTO 622×19 mean?
The 622×19 spec is what you need to pay attention to. 622 is the diameter of the rim bead seat in mm. 19 is the inner width of the rim in mm. Look at your tires, if they are marked ‘ISO 622’ or ‘ETRTO 622’ or ‘700C’ (an French system label that is the same as ETRTO/ISO 622), then they are 622mm diameter.

Can you change tire size on the same rim?
Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size. That being said, a vehicle with bigger rims will often be able to fit larger tires than other vehicles.

What size is a 622 tire?
In addition to its general size in inches, each tyre has a specific ETRTO number, which always follows the same structure. For instance, an ETRTO size of 37-622 means that the tyre is 37 mm wide and has an inner diameter of 622 mm.
Is 622 same as 700c?
Originally, 700C tyres were quite fat, to get the tyre to 700mm across, so ETRTO 622 and 700C describe the same wheel size but 622mm is the actual measurement of the rim while 700C describes the outer diameter of the tyre.
