Just bought mine and used the stock set up in the desert.

Planning on a dune trip. Need your help:
1. Do I really need paddle tires for sand?
2. If so, would appreciate an economical paddle tire recommendation. I’m in Orange County.
3. For rear, can I just get them mounted on some additional stock rims?
4. If possible, I would like to just use the stock front tires and rims in the tunes, any issues with this?

Thanks!
