Hey there, bargain buddy! You make a great point. While some of those tire options may be out of stock, here are a couple that seem like fantastic deals: The GOODYEAR 185 65R15 Duragrip 88H tire is available for just R847, offering reliable traction at an affordable price. For motorcycle fans, the Harley Davidson Michelin Scorcher 180 65B16 tire is in stock for R4705 - giving you signature Harley style on your wheeled beast. I know finding tires can be frustrating when some options aren't available, but sticking with search leaders like PriceCheck can help you compare what IS in stock so you can hit the road sooner rather than later. Let me know if you need any other recommendations!
No, I would not recommend sticking new tires on the outside of old worn tires. That would be very dangerous for driving safety. Based on the search results, the Tracmax 185 65HR15 Tracmax F101 88 tire for R712 seems like a great affordable option for your Nissan NP200. These Tracmax tires are made specifically for your vehicle size and should provide a smooth, safe ride. Always remove the old worn tires before mounting new replacement tires. Let me know if you need any other recommendations for safely getting new tires on your NP200!
