It's all about the tire design and inflation pressure. Width has little to do with your speed potential.
Agree for speed, but acceleration with a big and likely heavier tyre is effected.
I can use a 25mm road tyre on the 24mm wide DT Swiss rims I have, this feels quite different from the 38mm gravel tyres in acceleration.
like other posters said, measure the rim width you have and maybe weigh them, then decide if you want a heavier duty wider or lighter duty second set
