Q: What are the best 18-inch wheels for a Model Y overlanding build?

For adventure duty you want a smaller diameter with lots of sidewall and real strength, which is why an 18 is the go-to. This UP-05 package pairs forged 18×9 wheels with all-terrain tire options like the BFGoodrich Trail-Terrain T/A and Yokohama Geolandar A/T G015, and offers a more aggressive 18×9 +20 stance for extra track width. The taller sidewall soaks up trail hits, and the forged wheel with a 900 kg load rating takes the abuse.
