Rear wheel wide with front wheel normal

Any problems running a setup like that?
My TT rear wheel bearings gave up and I put in my road bike wheel. However, that wheel is wider than what my TT wheel was.
Any problem descending? Performance wise is it the same?

Thanks

I wouldn’t see why it would be a problem-a lot of riders use a 23mm up front and a 25 or 26mm rear tire.

Not sure what widths you are talking about but I have ran a 23 on the back and 19 on the front (Hed 3 with Bontrager Aerowing) for years. I think it kind of makes sense, the narrow front wheel is maybe more aero as it hits the wind, and the wider wheel on the back is more shielded from the wind and has lower rolling resistance.

Perfect thanks for the response!
