Most modern rims now have an internal rim width in the range of 23 to 25mm that work better with wider tires. Are you happy with your current rims?

Buying another set of wheels gives you more options. To improve overall on what you have already & if something happens/breakdowns, you won't have any down time because you now have a spare.
