On what car are these?? See, if you cannot afford properly good tires for your rim size, don't use such big rims in the first place! Use big rims for what, showing off only??    Even if you think the width provide extra grip but in fact better tires at smaller sizes may still outperform shit wide tires at the limit, especially their controllability. Note also wider tires will be easier to aquaplane, hence now you're thinking to use tires which is already noted as having shit aquaplaning resistance too at such wide sizes, so go figure how they will perform in the wet!    Actually IMHO shit tires like this is only suitable for people who has mad driving skills with lighting reflexes and very high sensitivity to sense the tires at the limit, in other words a professional/race driver. Normal drivers like us need better tires to compensate for our normal driving skill to keep us safer. So unless you're a pro driver, better avoid shit tires like this!
