im in the uk and i am in the finishing process off my ek4 b18 turbo, it will be running around 550 bhp and im hoping for a high 10. i am soo confsued about drag tyres, the car currently has 205-45-16 tyres on, can i buy drag tyres for these rims or do i have to buy different alloys? whats the maximum size tyre i can go for in an ek? Also i have found a supplier in the uk for sells hoosier drag tyres but i do not understand the measurements they use (not the brightest person when it comes to things like this so any help would be great. here is a few things from the website

this completely confuses me so any help would be much appreciated, which tyre would i need for my rim??

 

Looks like that is a chart for RWD cars widest front tire is 5" wide. The slicks all start off too big for what you have. and none of those are listed as a 16" wheel

 

from doing a bit of research and looking at cars who run slicks they all have really small alloys at the front with a huge tyre so i think i need to buy smaller alloys??? when it comes to tyres and drag racing i have no idea what im looking at so any more help would be great

 

24.5 on a 13" wheel
