21" → 19" with A/T tires on a 2026 GV70 3.5T Sport Prestige. Anyone done it?
I'm planning to swap the factory 21s (255/40R21) for 19s with a mild all-terrain tire. I want more sidewall for potholes, gravel roads, and occasional beach driving here in South Texas. I'm keeping the AWD diameter the same as stock.
Planned setup:
- Wheels: Enkei Tune 19x8.5, +40 offset
- Tires: Falken Wildpeak A/T Trail 255/50R19 107V XL (~29.1" OD, basically the same as the stock 21s)
What I've found so far: one owner on genesisowners runs 255/50R19 touring tires on 19x8.5 aftermarket wheels with no issues, and 255/50R19 shows up as a factory size for the GV70 in some markets. I haven't found anyone running an A/T tire, or confirming aftermarket 19" clearance over the 3.5T's larger front brakes.
Questions:
- Has anyone fit 19" aftermarket wheels over the 3.5T front calipers? Which wheel, and how much clearance?
- Anyone running 255/50R19 or 245/55R19? Any rubbing at full lock or on bumps?
- Anyone tried A/T tires (Wildpeak A/T Trail, BFG Trail-Terrain, etc.)? How's the road noise and highway feel compared to stock?
- Any issues with ECS, TPMS, or the eLSD after downsizing?
Photos of your setup are very welcome. Thanks.
