I am trying to find some good track tires for my 18" track wheels, i realy want the advan a048 but they dont come in the right size, its either 265's which are to small or 285's which are to big. What is a good track tire that comes in a 245 front and a 275 rear? I have a lot of power so i can't get anything small. Thanks for the help.

 

Not sure if you mean your stock 18" wheels. If they are than they are only 8" wide and you can only fit a max of 255's on them.
Now if you have a different wheel that is 9" or greater, than you are good to go with 275's.
Now when you say track - what do you mean? Drag, AutoX, or Road. They all have a different tire spec.
Drag - I have no Idea
AutoX - Kuhmo V710's (Don't drive these on the street as they wear very very fast)
Road - Toyo RA1 or Michelins Pilot Sport Cups (You can drive these on the street, but they still will wear very fast, most people put these on at the track)

 

when i say track i am refering to road course. I need R rated dot tires.
