I mainly ride on the street but I like to go off the road on trails from time to time, could I use

this on the front Michelin Pilot Street 2 (Front/Rear 70/90-17) https://www.cyclegear.com/tires/michelin-pilot-street-2-tires?sku_id=10042555

and

this on the back Michelin City Extra (Front/Rear 80/90-17) https://www.cyclegear.com/tires/michelin-city-extra-scooter-tires?sku_id=10144184

or should I just do 2 Pilot Street 2s with a (70/90-17) on the front and a (80/90-17) on the rear?

or are there any other recommendations for tires?
