I purchased 235/70-18 Michelin CrossClimate 2 XL tires for my 2017 Acura RDX Tech package. They are not in stock right now and they asked if I want to substitute 245/70-18 tires which are in stock. The 235's are h rated and the 245's are V rated as well as being 10 mm wider. Do you think the 245's would be noticeable stiffer riding? Sincde they are wider and V rated. I suspect they would be and I want a smooth riding tire.
