I would like all season tires on the Octa. If I change the 20 inch all terrain tires on a new Octa with 20 inch all season will it affect the ride or the speed I can go?

 

All seasons will be quieter, have more on-road grip, are more fuel efficient, will ride better, and they almost always carry a higher speed rating than an all-terrain.

If your OCTA was fitted from the factory with the BFG Trail Terrains, your top speed is limited to 130. If it was fitted with the Goodyear Duratracs, it is limited to 99. Putting all-seasons on a car originally fitted with all-terrains will not change the top speed. OCTAs fitted with the 22" all-season from the factory are the fastest with a top speed of 155.
