For the most versatile set up on stock suspension, we would recommend 255/65R17 (30x10R17) to give you an upgrade from stock, with minimal chance of rubbing.
The addition of any size lift kit will increase your clearance for larger tires. Please check with your installer to see what other tires sizes you may be able to fit with your set up.
Note: Our shop vehicles are a JK Wrangler Rubicon and a JL Wrangler with stock suspension. Tire size we chose was 295/70/17. This is the maximum size for street and there was very slight rubbing on the trails. We would recommend a lift kit or modified fenders if you want to use this configuration for serious offroading.
