Wheels & Tires - nittor dr

want to buy chrome z06 18 x 10.5 rims. was eiter deciding on the nittor 285/40ZR18 or 285/35ZR/18. would both these tires fir on those rims. and what is the difference between 40ZR and 35ZR?

the difference is the side wall height ...i would get the 35 for an 18in wheel

the 40 would be way to tall.
a 275/35/18 would be the correct size on a 18 but you have the wider wheel so i say the 285/35

i loved my 285s o my 17s, they are just wide enuf for an aggresive stance. i say go 285 or 295!!!
