Thanks. Would 225/70/16 or 225/65/16 be better? I don't know if there's advantage to having slightly smaller or larger wheel? I don't do off road driving, so am not too concerned about clearance.First: Welcome to the EOC!
Second: IMO, that tire is a little too wide for the stock rim, you will have a ton of buldge and your handling will suffer for sure, 225/65 would be safer, stock is perfect for our stock rims. Choose a tire that kerps you and your passengers safe. The tire would technically fit, but not correctly.
Also, I assume having larger wheels means the mileage counter rolls a little slower than it should, meaning car is being overworked, whereas having smaller wheels runs out the warranty a little sooner.
