Measurement Request: 345/30/20 MPSS on 12, 12.5 or 13” wheel

If anybody has 345/30/20 Michelin pilot super sports installed, could you measure and post the section width / overall width sidewall to sidewall and note the width of the wheel they’re on? Thanks in advance. 👍🏻

Do you mean besides what Tire Rack shows?
Yeah, I think they only show a measurement on a 12” wheel. Not sure if taken from manufacturers specs or a real world measurement.
They don’t grow with respect to the 13.8” which is the width of the thread basically. I have two sets on 12” wide wheels. I like them on the 12” wheels because of the good “cushion” in that measurement. I don’t have to worry about skidding expensive wheel rims when they are laid down on the floor. I have 325’s on 12’s also and don’t like that combo because even with the shown 13” width, they cause the edge of the rim to be in jeopardy if I am not careful handling them.

I don’t see the benefit to more than 12” wide wheels in this application. I own Cup 2’s and PS4S in that size and both are mounted on 12” wide wheels that look and perform great. The incremental benefit of a bit wider wheel, is hard to justify for me.
Great info. Thanks. I found a good deal on some 20x12 BC Forged wheels and contemplated swapping to 13” barrels since I have room on my application if it lays the tire out a bit wider. But, like you, I want that rim protection.

Which run widest of those 3 tires?
