V60 needs new wheels, 18 inches with all-year tire

Hello together, due to very good experiences with other cars I would like to change my V60 from summer + winter bikes to all-year tires. The look because of 18 inch rims, preferably the Volvo Magni in 8×18. As tires I chose the Vredestein Quatrac 5. The tires are available in 225/40 R18 92Y XL and 235/40 R18 95Y XL. As axle loads I have 1200 and 1050 kg in the vehicle license. With the Magni rims there is a recommendation 235/40, but then I need these steering limiters (I haven’t yet). Can I drive the Magni also with the 225/40s and then do without the steering limiters? Are the 92Y of the 225s enough? Currently 95W are in the vehicle license… What do the steering limiters cost with the V60 with standard drive unit including installation? I look forward to your feedback!
