I have replaced the mags on my 1100 Spirit with spoked wheels. I bought new tires for it, Dunlop D404's front and back. The rear tire was installed correctly according to the rotational arrow on the tire but the front was installed backwards according to the sidewall arrow. BUT....the treads, which are the same on both tires, match directionally. Should I get the front tire remounted with the tread going in the opposited direction of the rear or leave it? There's no issues handling, etc. with the tire as is just curious as to why there's the difference if the tread should rotate in the opposite direction for the front.
