will 18x9.5 rims fit on stock 18" 245 tires?

 

It's a stretch and it won't look right, but it will work.

 

i had the same question. obviously the 275 is reccomended, but i just ahd my wheels put on today using stock tire sizes. does not even looked stretched, looks perfectly normal. when these tires are bald i will upgrade to wider tires, but it does not look abnormal at all

 

it probably looks normal because the tires are 45 series.
