I bought new 2022 with 22in rims. Being new to this, I bought the Defender with 22. I don't want change the rims. I changed the tires to Toyo AT III. I was wondering if I can change my rims to 20inch without any modifications. Also If I can change tires to 275/50r22 tires. My sales rep told me I can but Landrover told me I shouldn't. Can anyone help me on this.
