i know, i know, i'm a noob, but quick question. if i just buy the tires and not new rims also, how do i get them on the rim when i want to go to the track? i don't have a mounting machine! should i buy two tires and two rims with them and keep them mounted?

 

yes i just bought a set of 4 roatas used for 220 with some beat to **** azinas on them...they look like slicks ...lol

 

if my rim is a 15x7,

will the 225/50/R15 size tire fit my rim?

 

Yes.
