bout to buy some rims 22's. reccomended tire size is 275 45. back spacing is 6.14" with 30mm offset. can i mount my 305 40's without problems?? also, purchasing 2 18's reccomended size is 285 55. back spacing is 5.15" with 10mm offset. could i mount the nitto 555r's at 305 45?

 

edit: nevermind. i called and they said they were sold out. where can i find some cheap wheels just to mound some drag radials too? also looking for a new set of 22's for the street but they have to be able to mount a 305/40 tire
