Messed up my tyre order, mix of cross climate 3 and cross climate 3 sport!??

​

I have an E class estate with staggered wheel sizes for the rear.

I needed 4 new tyres so went with cross climate 3's they were hard to find for the rears in my size Michelin Cross climate was the only brand that seems to do it in all weather.

I didn't notice when ordering but looks like I ordered and fitted cross climate 3 sport to the fronts but standard cross climate 3's on rear.

I don't think the non sports were available on the fronts and I don't think the sports were available on the rear either so I've obviously just picked the only availability Michelin all weather tyres on the filter.

I know it's fine as they are all matching on the axles but I'm really annoyed at myself as they were not cheap! Luckily I don't have a 4matic E350 just standard RWD

What is the difference in theae tyres? Sport vs non sport
